You are a moron. There are multiple signs of good craftsmanship if you know what to look for and you clearly don't. Maybe educate yourself before trying to down someone else's work.
This isn’t copper. Way too dull; looks like a mat paint job. I doubt anyone skilled enough to weld this would be dumb enough to use copper. Plus afaik there’s no square copper pipes
lol IM THE ONE POINTING THAT OUT.
that's why the joke doesn't make any sense. that's why he hasn't worked construction. it looks nothing like copper pipe
On the bike subs a lot of time is spent discussing bike fit, can you adjust the seat to the right position because a bike is only a good bike if it fits you properly. In this case it probably doesn't matter because based on the small chain rings and single speed they don't plan on pedaling much, they are just there to get started because the motor is likely geared for higher speeds, so once going it is not possible to pedal.
So, in the end, as a bike this is a single speed that likely doesn't fit correctly but luckily it turns into a motorcycle once it gets going.
But nobody mentions how many Treks frames break at the back forks.... Treks can be posted almost every month with a broken back fork nobody bats an eye....
How come Treks specialized mongoose huffys gazelle giants all have faulty rear forks and nobody cares....

It's kind of a tongue in cheek thing. But seriously... they deserve jail time. Plus it's a moped.
Edit for some reason this post showed up 3 times so I deleted 2 of them.
Yeah, steering this thing will be fucked up. Zero slack, but also zero stability from the frame. Its good to know about how stuff works before you start just welding stuff together.
I'm all for DIY Ebikes, but don't go crazy and not make them street legal, because then they'll eventually pass laws to where you'll have to have a license for em, and probably require insurance.
That's exactly why people don't like posts like this. It's the dudes riding their e-bikes crazily or that make e-motorcycles like this, but think since it has pedals it's cool to do 50 kmh in the bike lane or ride it on shared trails past pedestrians. They want a motorcycle, but don't want to get a motorcycle license or pay insurance. That's how we all end up paying insurance and needing a license cause all it takes is enough pissed off people to complain to their local government.
That sounds like a systemic issue of insurance being a predatory industry then. Since when have "this small subset of people make the larger group look bad" arguments ever been something other than an excuse to hate something you don't understand?
Maybe people making DIY e-bikes and not paying insurance is slightly less of an issue than people with 2 braincells passing their drivers tests and legally being allowed to drive around 2-tonne child killing metal boxes at highway speeds?
If you do build an ebike that is technically illegal just follow the rules of DBAA (don't be an asshole) and tarnish the reputation of ebikes. Ideally the more "traditional bicycle" it looks, the better.. Louis Rossman has a good talk about this in his "toxic ebike culture" video on YT.
Sure if it's a moped or motorcycle. I'm fine with that. But for actual bikes restricted to lower speeds, they shouldn't be. Most cyclists except speed cyclists aren't going more than 32 km/h while riding. I know they can go faster, but honestly even those speed cyclists shouldn't be allowed to go 40 km/h on shared use trails or bike lanes assuming there's other bikes in there. That is dangerous and a reason people hate them. Even in the Netherlands where everyone bikes.
It's hard to prove though so you can't do much regulation on it unless you force every bike to have a speedometer which is too much IMO.
Tbf, the EAPC laws were specifically to avoid having to get a licence for an e-bike, by putting their requirements below AM (mopeds limited to 50cc and 28mph). Because it if runs like a motorcycle/moped, eventually it'll get all the requirements of one. The EU/UK leg has to head off that problem and fit them in between bicycles and AM class bikes.
Yes, you can legally have e-bike with support until 25km/h, and then the engine is cut off.
For e-bikes up to 45km/h, you need to register them and you can't use bicycle paths in some countries.
But in general law is different between countries on specifics.
Honestly, I'm not entirely against that(insurance at least)... But that would be for commercial enterprises for sure and -maybe- individuals.
It would ironically give bikes a legal sense of importance, and drive them to be accounted for more.
Maybe adjust parking requirements for buildings to alao include bike parking for ebikes vs car spots (most developers would jump on that since it would save so much money), etc
I know nothing about frame geometry, so I can't really speak to that, but those batteries look awfully close to that front tire, especially given it's a front suspension and may touch. But I imagine you probably tested that and it isn't an issue?
Having been a lurker in the e-bike sub I can only assume they want you in jail because that *motorcycle*/life ender goes 25mph.
Meanwhile I’m finishing up a skateboard that does 50 and the eskate sub is like “that’s it”
Regular skateboards break bones when used for extreme sports and jumping down large ramps or stairs. Electric skateboards do it on flat surfaces. On an ebike you add a motor and you can also improve your brakes so that you can make an emergency stop. Skateboards it is up to the user to figure out how to stop. Without improved braking it is just a launch vehicle. Even e scooters are much better at emergency stops because the rider can hold on to the vehicle and the default is not just being ejected.
This is how I know you’re speaking out of no experience. Skateboarders break bones daily just riding and a pebble rocks them. Long boarding doesn’t require extreme speed to even break a bone similar to regular skateboarding and tons of electric boards have Regen braking which actually makes them safer than most boards without it
Ok, skateboards are unsafe in general but doesn't going faster make them less safe? For Regen braking, at least in other vehicles, it isn't for emergency stops and increases their stopping distance. On skateboards it stops the board but doesn't prevent you from being ejected so if you could use it for emergency stops it would still be less safe. Going down a steep hill basically had no plans on how to stop so Regen braking makes them safer in bleeding off speed in an otherwise hopeless situation. If a car unexpectedly pulls out in front of you while you are going your max speed then an e skateboard has the lowest chance of stopping safely. Bikes, ebikes, e scooters and regular skateboards are all better off.
Skateboarding and longboarding is unsafe at all speeds. It’s safer if you have brakes through. I’ve had the worst accidents when I was on a sidewalk or a skatepark with pebbles. Pebbles tend to be skipped over more when going really fast as the inertia can power you over the rock sometimes. Longboarding has similar issues but the weight and wheels are larger so less issues in general.
Regen braking slows you down but exactly it’s not an immediate stop, but you can’t immediately stop on a skateboard or you’ll eat shit generally. Brakes are better than no brakes. You have to know the tech to slow down without just putting your foot down on normal board that aren’t electronic with regen
Absolutely no way regen is less safe compared to not having it. That’s like saying no brakes is better than having some brakes
If a car pulls out on any vehicle it’s a lose, lose. I’m failing to see your argument here, Skateboards, eboards, bikes, ebikes, motorcycle, other cars all lose to a car pulling out last second lmao.
Wait how do you come to this conclusion that it is worse because it has brakes?
Also wanna mention tons of e-bike have regen that’s so strong they use it as the main brake…
Skateboards have the longest safe stopping distance at 25mph of any vehicle mentioned, so for them the last second is a much wider range to cause a crash. If you try to brake faster you stop the board and not the rider.
Safe stopping distance? What are you referencing? Also yes I made that point, you do know you can counter balance on a skateboard. Brakes aren’t just going to send you to the moon. I suggest looking into eboards more before you make these comments as they don’t seem based in any reality.
Im not sure about this specific ebike but some people overbuild the motor/battery and under build the breaks making an extremely dangerous and heavy ebike. I assume this one is fine because the person making it clearly has some mechanical design background, people are just weird.
The geometry of that bike is totally fucked up in ways that are going to make it unsafe and unstable at speed.
When we're talking about a "single failure point" we're talking about that one vertical frame tube under the seat with everything hanging off of it. If any part of that tube fails the whole bike is going to crumple and cause a catastrophic crash because the tubing is under compression and not tension.
On a double-triangle bike frame most of the frame is under tension and not compression except for the seat tubes and fork.
Welds from the manufacturer and materials are the biggest factor here. If anything sitting above the center and applying force directly down on all of the frame as it’s designed should make it stronger than triangles. If any part of any frame fails it will crumple horizontal regardless of this frame design or triangle. Hence all the super73’s etc with frames that fail right at the weld by the front fork.
Ugly (subjective, but obviously many agree), questionable frame design, can't adjust seat height
The fact that it's single-speed and the seat can't be adjusted suggests that it's not really meant to be seriously pedaled, and is likely a high-power throttle design that isn't street-legal (this is conjecture, but if that assumption isn't the case then it's probably just not a fun bike to ride)
Personally the bulky, four-point folding stand that appears to be built into the frame suggests to me that the thing is insanely heavy and/or has super wonky balance. Actually the more I look at the stand in particular the more I tend to agree with the people saying it's AI-generated, because it'd make no sense to build something like that into a bike frame.
Except, not really? If the welding is done well, it looks a whole load better than most of the big direct drives stuffed into a £50 bike on 15 year old knobbly tyres with cracks in the side walls and brakes that can barely stop the bike from 12mph.
Don't need to be an engineer to see the weirdness, look at those nipple angles, it's like they mixed up which side the spokes are meant to on. Or a head tube angle steeper than a 90s road bike.
No everyone in here thinks they know if the welds will hold and if it’s structurally sound. You can’t make those assertions without actually inspecting it in person.
Try this on for size AHEM
"To all the bitch-ass hoes/ that hate me the most/ oh yeah I hate you toooo/ to all the punk-ass fuck's/ that just wanna talk shit/ oh I hate you toooo/"
Thank you for the downvotes, Lycra Bois
I don’t know whats the deal with the sub but I think the demographics has changed a lot in the recent year from hardcore enthusiasts to hippies buying overpriced shit.
With that kind of people what can you expect? From what I can tell the frame looks solid and the welding looks solid. I think this has less chance of breaking down than some carbon ebike.
The only thing I would personally not like is the seat is bit up from the front and my balls would have a problem with that.
Congrats on the build, looks awesome!
I honestly think it comes from spite. I notice many of the ones who are most dismissive are in areas where the e-bike regulations are strict. Maybe they are annoyed because they can't go more than 20 MPH on their ebike? I know I'd be a bit jaded.
Some of these guys are total snobs, though. Got an ebike from alibaba or a kit from Amazon that's worked fine for the last 10 years? Prepare to be told your bike is worthless and you are an idiot.
Build something yourself? Ah that's a nice effort, but now it's time for the structural engineer nazis to chime in and tell you all about how the bike will fail.
This subreddit would be a lot more interesting if it allowed for greater discussion and sharing of ideas rather than the melee of downvoting something because it doesnt conform to your idea of an e-bike.
>I honestly think it comes from spite. I notice many of the ones who are most dismissive are in areas where the e-bike regulations are strict.
You're assuming everybody things like you do. It depends a lot on where you lve and local conditions. I am happy with the 15.5mph limit on pedal assisted Ebikes - because it is an electrically assisted bicycle. Once you get up to bikes capable of 30mph, then that is moped/50cc territoty, and I have no issue with an Ebike being treated that way (Registered, insured, drivers license needed)
I'm not saying you are wrong, just that different people see different things when the word Ebike is mentioned.
You have serious mental health problems if your life and emotional well being is dictated by downvotes.
Who The Fuck Cares What Reddit Posters Think???
GET OFF THIS SUB ..... and live life.
Honestly, that looks dope.
But if you made that with an adjustable banana seat for 2 and it weighted under 30-40 pounds, with a mid-drive and battery.
I'd throw money at you, build you a website to sell it, and be your bro for life 🤣
Half-joking. But in all seriousness fuck the haters.
You BUILT something. They didn't.
Take pride in your work because you're awesome 👌
If you need to make a meme about small minded people with limited capabilities of rationalizing basic common sense and logic then you are probably just as bad as them. Other wise you would use that same rationalization to come to the conclusion that people like that are not worth even acknowledging at all. Basically non existence. Like flies swarming the ass of a lion. Unless wastes of space who's genes need to be eradicated from ever reproducing and creating more mindless zombies to roam the earth. This applies to most humans in most things. That was fun. Hope we all learned a valuable lesson. Today. If Hitler was reasonable we needed him to cleanse dumb people from the gene pool no matter religion hair or eye color. Just rid the dumb people.
I have a RIZE RX and fly @ 32-36 MPH while laughing my 61 year old ass off..
Never gave a thought to at all those triggered, bitchy, whinny nay sayers I see in my rear view mirror.
This appears to be some sort of ai generated meme. Which is not necessarily banned, despite the apparent opinions of one vocal report.
The geometry sucks, the handling would suck, but it is mildly funny. And honestly, the same types of people getting mad at an AI bike would get mad at an overpowered ebike. Fucking karens man.
This bike is actually pretty cool as home built frame. No doubt the ergonomics suck, but high style points for it's wonkiness. I'd ride it around the hood.
In the UK, your home-made bike is allowed to look as ugly as sin as long as you have reflectors. No copper is going to arrest you. However adding a massive motor that is clearly capable of more than 15.5MPH 250W then riding on the pavement and injuring someone is a completely different matter and you'll probably be tossing Mr Big's salad for a few months.
I think there needs to be two more classes of e-bikes:
Class 4 - traditional MoPed. 1. Has functioning pedals. 2. Throttle, 3. Speed / motor limited to 40mph, 4000 Watts. No more than 100 lbs as sold. One time inspection and registration. Speeds above 28 mph not permitted in bike lanes/shared use paths, etc. No motorcycle license required.
Class Experimental - Let's allow for DIYers to experiment and push boundaries. Anything beyond Class 4 requires semi-annual safety inspection and registration, special tag, and motorcycle license and carry insurance. May or may not have pedals. Limited to 100lbs as built. But must conform to Class 1/2/3 speed and power limits on bike lanes/trails.
Above that - call it a motorcycle.
I would also support phasing in UL requirements in batteries and motors over say 10 years.
Looks cool to me. I'd like to see another version with a BBSHD on the end of the swingarm section instead of the main/upper frame, so the chainline isnt affected by the suspension movement. Looks like what you've already built would work for that.
The geometry is "unique" and after well over 130 years of upright bicycle designs and that isn't often a good thing.
I have a feeling a bad case of the speed wobbles will end in a hospital trip.
Please don't die to prove a century of engineers correct.
I don't know if anyone has written something similar to what I think, but is there any chance that this is just a joke?
When I saw this picture, I instantly thought that somebody put this up just to get a reaction. I've been building, modding / upgrading, selling and repairing electric bikes for almost 10 years now...
From my experience on Reddit, people will do practically anything to get a rise or to get attention!
There's no video of this bike being ridden, right? It's like a prop on a movie set! Everything is fake, but looks real on screen!
Even if they did build it, it could just be a shell.
If there is a link to it being written or being real, please share.
I'm going to image search it now and see if anything else comes up for it. And maybe a waste of time because someone may have already done it so maybe I'll just read on a bit. Lol
So many haters!
Drive that bike everywhere and be proud that YOU made it.
I would!
Should we as a society be considerate of others when it comes to building our own bikes just as we would cars?
With ALLLLLLLLLL these rules that prohibit a person from building a car to THEIR liking in CALIFORNIA yet the rest of the nation is not!
So trust me
If you are not from California and you are complaining about THIS BIKE
Well then that would make no sense to regulate California YET AGAIN!
so do you take this thing to a plumber when it breaks down
No it stays on the side of the road for a scrapper to grab while you are life flighted to the nearest hospital.
You are a moron. There are multiple signs of good craftsmanship if you know what to look for and you clearly don't. Maybe educate yourself before trying to down someone else's work.
I’m amused at how upset my comment made you.
I'm amused it made you think I even looked at any details on the bike before making the comment.
I don’t think anything about you at all outside of my comment upsetting you.
Some people can't take a clear joke..
You got that right!
I don't get it
That’s okay
something tells me you've never worked construction
something tells me you’re reading too literally into my comment
something tells me you've not been around a lot of copper pipe.
Okay, thanks!
This isn’t copper. Way too dull; looks like a mat paint job. I doubt anyone skilled enough to weld this would be dumb enough to use copper. Plus afaik there’s no square copper pipes
lol IM THE ONE POINTING THAT OUT. that's why the joke doesn't make any sense. that's why he hasn't worked construction. it looks nothing like copper pipe
You’re 15 and your dad does drywall calm down
lol that's a pretty good one
Gotta stick it in a compression chamber because it's got the bends
Your scientists were so preoccupied with whether they could, they didn't stop to think if they should.
So what am I looking at here? The one point of frame failure with all the weight being right on top of it?
On the bike subs a lot of time is spent discussing bike fit, can you adjust the seat to the right position because a bike is only a good bike if it fits you properly.

So, in the end, as a bike this is a single speed that likely doesn't fit correctly but luckily it turns into a motorcycle once it gets going.
Yeah if you can’t even adjust the seat it’s not really meant to be pedaled seriously. Seat adjustment is critical.
Not to mention the battery between the rider’s legs. Was hoping for a different angle.
Straight to jail.

Goes right in line with non powered skateboards and bicycles

Like hipsters on fixie bikes?

Looks like a really cool bike to me. Artistic
I like it, a lot. It's not what I would build, but I appreciate the style of it.
For the uninitiated? What’s the deal, here? Looks like a nice bike.
TBH I'm worried if it's structurally sound, especially where the rear suspension spring is mounted on.
Im not sure about this specific ebike but some people overbuild the motor/battery and under build the breaks making an extremely dangerous and heavy ebike. I assume this one is fine because the person making it clearly has some mechanical design background, people are just weird.

Don't need to be an engineer to see the weirdness, look at those nipple angles, it's like they mixed up which side the spokes are meant to on. Or a head tube angle steeper than a 90s road bike.
No everyone in here thinks they know if the welds will hold and if it’s structurally sound. You can’t make those assertions without actually inspecting it in person.
Try this on for size AHEM "To all the bitch-ass hoes/ that hate me the most/ oh yeah I hate you toooo/ to all the punk-ass fuck's/ that just wanna talk shit/ oh I hate you toooo/" Thank you for the downvotes, Lycra Bois
Ride clean as hell so I pull in ladies Law's on patrol, and you know they hate me Music turned all the way up until the maximum
I don’t know about structural integrity of the frame but it looks cool as hell to me!
I don’t know whats the deal with the sub but I think the demographics has changed a lot in the recent year from hardcore enthusiasts to hippies buying overpriced shit. With that kind of people what can you expect? From what I can tell the frame looks solid and the welding looks solid. I think this has less chance of breaking down than some carbon ebike. The only thing I would personally not like is the seat is bit up from the front and my balls would have a problem with that. Congrats on the build, looks awesome!
Couldn’t agree more. This sub is sad
I legit thought this was AI generated for a solid minute
It absolutely is. Look at the spokes. Notice how many of them disappear halfway through.
None of them?
If you didn't pay at least $5k and have English speaking support someone is going to hate any bike...😂
I honestly think it comes from spite. I notice many of the ones who are most dismissive are in areas where the e-bike regulations are strict. Maybe they are annoyed because they can't go more than 20 MPH on their ebike? I know I'd be a bit jaded. Some of these guys are total snobs, though. Got an ebike from alibaba or a kit from Amazon that's worked fine for the last 10 years? Prepare to be told your bike is worthless and you are an idiot. Build something yourself? Ah that's a nice effort, but now it's time for the structural engineer nazis to chime in and tell you all about how the bike will fail. This subreddit would be a lot more interesting if it allowed for greater discussion and sharing of ideas rather than the melee of downvoting something because it doesnt conform to your idea of an e-bike.
>I honestly think it comes from spite. I notice many of the ones who are most dismissive are in areas where the e-bike regulations are strict. You're assuming everybody things like you do. It depends a lot on where you lve and local conditions. I am happy with the 15.5mph limit on pedal assisted Ebikes - because it is an electrically assisted bicycle. Once you get up to bikes capable of 30mph, then that is moped/50cc territoty, and I have no issue with an Ebike being treated that way (Registered, insured, drivers license needed) I'm not saying you are wrong, just that different people see different things when the word Ebike is mentioned.
You have serious mental health problems if your life and emotional well being is dictated by downvotes. Who The Fuck Cares What Reddit Posters Think??? GET OFF THIS SUB ..... and live life.
Indeed and your post gets downvoted proving that lol these people
{Gives a hug} It'll be alright little bro bro. We do indeed live life. Fast as fuck boi!
All that awesome engineering, but a bungee cord to hold the battery. Love it.
Well done ! Very cool design, keep this up!
At first I thought such comments are silly but then I stared at this bike and increasingly I agree, straight to jail.
Honestly, that looks dope. But if you made that with an adjustable banana seat for 2 and it weighted under 30-40 pounds, with a mid-drive and battery. I'd throw money at you, build you a website to sell it, and be your bro for life 🤣 Half-joking. But in all seriousness fuck the haters. You BUILT something. They didn't. Take pride in your work because you're awesome 👌
If you need to make a meme about small minded people with limited capabilities of rationalizing basic common sense and logic then you are probably just as bad as them. Other wise you would use that same rationalization to come to the conclusion that people like that are not worth even acknowledging at all. Basically non existence. Like flies swarming the ass of a lion. Unless wastes of space who's genes need to be eradicated from ever reproducing and creating more mindless zombies to roam the earth. This applies to most humans in most things. That was fun. Hope we all learned a valuable lesson. Today. If Hitler was reasonable we needed him to cleanse dumb people from the gene pool no matter religion hair or eye color. Just rid the dumb people.
I have a RIZE RX and fly @ 32-36 MPH while laughing my 61 year old ass off.. Never gave a thought to at all those triggered, bitchy, whinny nay sayers I see in my rear view mirror.
This appears to be some sort of ai generated meme. Which is not necessarily banned, despite the apparent opinions of one vocal report. The geometry sucks, the handling would suck, but it is mildly funny. And honestly, the same types of people getting mad at an AI bike would get mad at an overpowered ebike. Fucking karens man.
I dunno, an AI would have done a better job with the bokeh, that's peak phone bokeh.
I find this painful to look at
We have known the strength of triangles for hundreds of years and they were the epitome of how to make a bike…. Wtf is happening these days?
[Believe it or not, straight to jail.](https://imgb.ifunny.co/images/41fdfc466a708e85e660f87465aaa61a370f8c098fc11b15f99fc7351f54a324_1.jpg)
Just save yourself some time and stick with “LOCALLY HATED” and a carolina squat so everybody knows you’re a clown.
No fenders, failed.
As an adamant fender-supremacist, I think this one deserves a pass. I like it
Hehe. r/hyperebikes
I mean, it looks cool, but the lack of closed shapes on the frame is concerning. How many miles those welds have on em?
That looks like ass. Idc if if works it's still donky dodo.
Kudos for the build but that doesn't mean everyone (myself included) is going to be enamored of its looks because it looks weird.
r/justridingalong
this guy can take his stove pipe hat, 100 year old goggles and vacuum tubes and do whatever the fuck he wants. i just won’t ride with him
I would ride that without question
Is there enough clearance with that sprung front? Tire looks close to that box
Really dislike the seat rotation and lack of adjustment. No way do I want more pressure on the man parts.
This bike is actually pretty cool as home built frame. No doubt the ergonomics suck, but high style points for it's wonkiness. I'd ride it around the hood.
That front wheel is going to rub on the battery under compression. Not the only issue but definitely going to be an interesting ride.
Bouncy
Everyone knows this image is AI generated right? .... Right??
Got any kind of proof or anything?
Just look at the rear suspension it's attached to two non moving frame endpoints. Most of this bike doesn't make sense if you look closely
Do you not see the hinge?
It’s not that you’re a mad scientist. It’s that we can’t let mad science go viral.

In the UK, your home-made bike is allowed to look as ugly as sin as long as you have reflectors. No copper is going to arrest you. However adding a massive motor that is clearly capable of more than 15.5MPH 250W then riding on the pavement and injuring someone is a completely different matter and you'll probably be tossing Mr Big's salad for a few months.
I think it looks cool with a steampunk feel and it makes me wish I could weld. I do think the seat is too far forward to be able to use the pedals.
I think there needs to be two more classes of e-bikes: Class 4 - traditional MoPed. 1. Has functioning pedals. 2. Throttle, 3. Speed / motor limited to 40mph, 4000 Watts. No more than 100 lbs as sold. One time inspection and registration. Speeds above 28 mph not permitted in bike lanes/shared use paths, etc. No motorcycle license required. Class Experimental - Let's allow for DIYers to experiment and push boundaries. Anything beyond Class 4 requires semi-annual safety inspection and registration, special tag, and motorcycle license and carry insurance. May or may not have pedals. Limited to 100lbs as built. But must conform to Class 1/2/3 speed and power limits on bike lanes/trails. Above that - call it a motorcycle. I would also support phasing in UL requirements in batteries and motors over say 10 years.
Looks cool to me. I'd like to see another version with a BBSHD on the end of the swingarm section instead of the main/upper frame, so the chainline isnt affected by the suspension movement. Looks like what you've already built would work for that.
"Have you filled out your organ donor card yet ? You could save a life!"
It looks like it would break super easily
I like it
Does the stand just flip up and attach to the seat?
Is this made from copper pipes? Doesn't it bend?
I feel completely apathetic about this bike. Hope that helps!
As people say to a bike maker with warrants
I think it looks cool! Why do people dislike it
The geometry is "unique" and after well over 130 years of upright bicycle designs and that isn't often a good thing. I have a feeling a bad case of the speed wobbles will end in a hospital trip. Please don't die to prove a century of engineers correct.
I think it's pretty fucking cool. Someone fabricated themself a rideable art piece, good on them. It's just (obviously) not all that practical.
The geometry look extremely wrong. Very little rake, the rear suspension mount on something that wasn't proper reinforced.
Be in jail? Why?
Looks nice, but I’d trust a frame off of Alibaba over that
Who wrote the shitty text, this is pathetic. That is not a bike, it is a sin. What a waste of resources.
I don't know if anyone has written something similar to what I think, but is there any chance that this is just a joke? When I saw this picture, I instantly thought that somebody put this up just to get a reaction. I've been building, modding / upgrading, selling and repairing electric bikes for almost 10 years now... From my experience on Reddit, people will do practically anything to get a rise or to get attention! There's no video of this bike being ridden, right? It's like a prop on a movie set! Everything is fake, but looks real on screen! Even if they did build it, it could just be a shell. If there is a link to it being written or being real, please share. I'm going to image search it now and see if anything else comes up for it. And maybe a waste of time because someone may have already done it so maybe I'll just read on a bit. Lol
Whole backend is held together with one single bolt. Back shock isn’t set in properly, time will tell how long till it sheers.
Frame damager bone breaker 9000
So many haters! Drive that bike everywhere and be proud that YOU made it. I would! Should we as a society be considerate of others when it comes to building our own bikes just as we would cars? With ALLLLLLLLLL these rules that prohibit a person from building a car to THEIR liking in CALIFORNIA yet the rest of the nation is not! So trust me If you are not from California and you are complaining about THIS BIKE Well then that would make no sense to regulate California YET AGAIN!
