hi dude, well i can give you a few good ideas, perhaps if you change the front wheel for one more bigger your project colud be look stupidless, and the second the back wheel could be close the star and from this way you don't use a chain o the breaks too like the olds bikes with the pedals think that bro cyaa, and good luck.............
this is really cool but, it seems there's no neutral (like a regular bike). like if you are going down a hill and the pedals keep spinning with the rpm's.beat your legs off trying to stop it.
The pedals are too low to the ground. Also you can't fix the puncture in a rear wheel off the tyre. Why would I need a hubless wheel on my pedal cycle (I commute 52 miles a day on my bike), and therefore I disapprove of this design...
The problem is they are very inefficient and look like they always will be. Bikes, by design, are highly efficient with chain and crank. I don't see this overcoming that mechanical advantage.
@beerman1957 Yes the diamond frame cycle is the most ergonomically efficient means of travelling between two points under human power and anything which competes with it has a very long way to go. This hubless trash doesn't even come close.
@rodmantion Because it's 'compact' nature is it's only saleable asset. People can argue the hubless technology is crap but they can't argue that it will fit into the boot/trunk of a car.
@MrDichotomies it would never reach a high speed and if it did that hubless wheel would erupt into pieces. This is why you only ever see them demonstrated at walking pace
@MrDichotomies Not sure exactly what anyone is referring to any more - we seem to have drifted from the hubless compact to recumbents and semi recumbants. I would say this hubless thing is worse than useless because it will be a very expensive useless thing that will break down in no time at all. Although I am no fan of recumbants or semis I wouldn't go so far as to say they are useless but merely that they have very limited uses. If you live on flat windless ground then maybe they are for you.
@CompactJam I was referring to the useless hubless design. I like recumbents. Thought about getting one to use as a touring bike. But I like to go fast downhill...
I don't know why people like these so much, there is ten time the friction of a normal hub, and they look like shit. And it's a bitch to change a tire. And it weighs ten times as much.
You really should work on a folding commuter bike with this rear wheel you have all the space needed to totally fold into. I could see it really get into production as there is less new tech here than most folding bikes!
@sanddragon99 Thank you. You have proven my point very well. You don't care if it works or not as long as it looks good but you wouldn't even want one if everyone else had one. In other words it's made and designed for idiots that want to strut around posing on a piece of engineering crap. I was a professional cycle courier for years and this junk wouldn't last five minutes on the road. Even it did the geometry of it is inherently dangerous. It would only ever be good for American vain morons
@CompactJam hank you, that's exactly the problem. If it's not exactly like what you're used to it's scary and unfamiliar.
I don't think it would handle like your current bike or last as long in hard service. It's essentially a compact bike with a large rear wheel, and no compact bike will handle well or hold up to hard use. That's not what they're for.
Personally, I have trouble folding a courier bike and strapping it to the motorcycle for trips. I might have different needs.
@Hikikomori013 It's nothing to do with strange and unfamiliar or being compact. It's to do with it costing a hundred times more and serving utterly no function other than to make it more expensive and not withstand impact. If you have different needs then you obviously want a wheel that costs more to buy and service, is inherently unstable and breaks whenever you hit an obstacle. Motoring advances mostly come from the Gran Prix and cycling advances come from Tour de France and no one uses this.
@CompactJam What a wonderful coincidence. A Tour de France bike would be totally useless and impractical for what I need a bike for.
Most of the technology developed for the Tour seems intended to shave a fraction of a second at the expense of making the bike more fragile and expensive to operate.
@Hikikomori013 You're either very stupid or just trying hard. You don't drive an F1 car either or a moto GP bike but your machines benefit from their developments as they trickle down into mainstream technology. TdF bikes are not as you think built only built to shave seconds. They are built to be rugged and reliable in all weathers and over a variety of surfaces and to have smooth changes and safe geometry. These benefits are to be found in the steel horse I rode as a courier.
@CompactJam I did a survey of my bike. The frame and wheels are old commuter technology from the days when high wheelers were the choice for speed. The pneumatic tires were built for commuting comfort on cobblestone roads. In fact the only specifically racing technology I found was the derailleurs, which are fragile maintenance hogs. Hub gears are much more reliable for my use. No good for racing, though.
@Hikikomori013 All of that is correct. Hub gears are far more durable and weatherproof although they do require specialist servicing. Quite what that has to do with hubless technology is beyond me though but thanks for the info about your bike. Small wheels like the one above, and especially front ones, are treacherous on sweeping bends. Also when you hit obstacles they tend to cause you to pitch forward and 'take a header' This is why the diamond or 'safety' frame is universally known as best
@CompactJam I think recumbents are safer, but not allowed in racing. They won too many races when they started competing, so they were banned as not being proper bicycles.
@Hikikomori013 Don't even start me on recumbants. They too are inherently unsafe because of their small wheels and low wheel base. They are deadly in traffic because many drivers can't see them up close. Their weight is centred too far back so they can't climb steep hills without the front wheels taking off. You can't track stand or balance on them and have to shoe out when you stop. Yes UCI banned them although they did win a very few specific type of race. Good on flat ground or velodromes.
@Hikikomori013 You can only ride them with cleated shoes because your feet would simply fall off the pedals otherwise. The ones with a full housing are banned from road in this country because they obscure vision. They are vulnerable to cross winds and only operate better in ideal conditions. I have done many long distance rides over hilly terrain and overtaken them all day and never been overtaken by one. They are also immensely heavier for hill climbing and have problems with the long chains.
@CompactJam I'm doing it wrong. I've always worn street shoes, never fell off the pedals, and I never track stand anyway so it hasn't been a problem. The chain hasn't given any trouble. It's also immune to pitching forward in emergencies.
But I can't recommend them. Or a folder, a compact, or anything else outside of your use, regardless of how well they work for anyone else's purpose. All worthless, all outside approved orthodoxy..
@Hikikomori013 God you're trying hard aren't you? Your chain probably hasn't stretched yet because you don't use it much. When it does it will cost you eight times a normal chain because it is eight chains stuck together. Recumbents pitch backwards on hills not forwards so I assume you don't ride steep inclines. Hill climbing of course stretches and wears chains much quicker too. If you're not using cleats it must be a semi recumbent. Very hard to view behind you too without mirrors.
@CompactJam Twice as long, and I had to cut the second chain down.
I haven't found any hills steep enough to lift the front wheel, but then on really steep hills I've always walked, even on the diamond frames. Let someone else play macho.
If it makes you feel better, I did pitch over forward once. I was on a racing style 10 speed and hit the brakes. Ended up running down the road with the bike flipping over behind me.
@Hikikomori013 I love you Hiki - you're a real trier. I'll give you that. Erm hang on. No you get off and walk up hills. Alright skip the trying part. And no I don't take any pleasure from you face planting. I've had more knocks than a brothel's front door from cycling so I know what they are like. Fact remains this hubless thingy is complete poop. It is a technological dead end except for posing at low speed.
@CompactJam The disadvantage of the hubless wheel is the precision machining required and that they haven't developed the seals for extended use yet. It can be difficult to connect the drive. The technology is new and undeveloped.
The advantages are the larger diameter reducing side loads from the leverage of the wheel against the bearings and reduced weight and windage.
Whether the advantages outweigh the limits will have to wait until they're developed and in the market.
@Hikikomori013 No - there are only disadvantages and they are almost endless. The friction is a hundred times more, you have to disassemble the frame to change a tyre, they attract dirt, they weigh a hundred times more than a real wheel, any litter like a carrier bag feeding into it will kill it, any impact at all with break it because all shock is directed through the fragile drive system, they would always cost more - it's a technological DEAD END. Go and buy one and then tell me!!
@CompactJam Well, since you know more than the engineers who work on it I'll have to take your word on it, but 100 times? Is this as precise as your 12 chain claim? Do they really weigh 50 to 100 pounds?
But I agree that they are probably a dead end. Reactionaries won't touch anything noticably new. They'll make up all sorts of reasons why it must be bad and stick to antique technology until a professional racer rides it. They all want to pretend to be the racer dude.
@Hikikomori013 That's why my 400cc single cylinder scooter has no noticeable flywheel. Without a proper flywheel my low end torque is gone, it idles rough and I get poor gas mileage. But the racing bikes don't have the flywheel so they can shift faster at Laguna Seca.
I have an auto tranny. I don't shift, and I'm not going to race a scooter professionally. But racers have ultra light flywheels, so I have one, too. Fashion is more important than function on 2 wheelers.
@CompactJam I have good news for you. While the hubless has only been around since about 1990, and still hasn't been fully developed, it will still enter the market as a competitor, not a replacement. It will succeed or fail on its own merits, regardless of your hyperbolic attacks.
But you won't be forced to have one. You're safe.
@CompactJam Thank you far that lucid and rationally argued rebuttal. Let's pretend like you didn't have this outburst, shall we?
In the end it's just a technology. It works or it doesn't based on its own merits, and even if it doesn't work in the end it could start something that makes a real improvement in the technology you use now..
@Hikikomori013 And yes I probably do know more than the engineers who entertained this waste of money because it's fairly obvious none of them have ever spent ten hours a day in the saddle or done roadside repairs.
@CompactJam Another advantage of the hubless wheel: Since the hub is almost the same size as the rim a single side rear end can be built with a fraction of the torsion load, so the rear tire can be changed without removing the wheel.
Sbarro uses them for his performance sport cars. He doesn't know they don't work.
I also like center-hub steering, although it doesn't look like the current race bikes.
@CompactJam I would like to hear your opinion on the CruzBike which is a recumbant with a front wheel drive. I have no recumbant experience but to me this solutions seems a lot more sensible?
@nilo2209 The CruzBike is not a true recumbent but a semi recumbant somewhat reminiscent of the eBike which failed due to breaking up. They have clearly sought to overcome some of the design problems I spoke about. A higher wheelbase and a shorter drive chain less prone to stretching. The front wheel drive will limit the turning arc a bit but generally they appear to have done a fair job of reducing weight. It is however a hybrid and will not give you the low profile advantages of a true rec.
@nilo2209 The advantages of it though are that you can use fairly standard equipment and parts. You will also be reasonably safe in traffic as others can see you. (I would still fix a long bouncy pendant flag though) On the downside it is still heavier than a road bike and you cannot climb out of the saddle on hills and 'ride the rivet.' The frame size appears to be very particular too as you can only adjust the leg length and not the saddle position or height.
@nilo2209 You're welcome sir. It's only my opinion based on about thirty years of cycling, including as a pro rider. But it is unbiased. I'm not shop staff trying to sell you anything and I don't work for any producer.
@nilo2209 The CruzBike is a regular mountain bike with a standard drive train mounted on the front fork, and swinging with the steering. There's even a conversion kit you can mount on your mountain bike.There's a steep learning curve, but anyone can develop the technique, then you can ride no-hands.
The compact long wheel base is another option. They're fairly small and easy to learn. The Sun EZ1 is a good machine.
@Hikikomori013 However commuter bikes still have evolved from racing technology although all cycling technology (except the materials) is basically of the nineteenth century. Drive chains and cables etc. tubular frames and cams. Even the old penny farthings were raced competitively back in the day. Derailluers are fragile which is why couriers ride single speed. The larger track guage chains make them even tougher. There are no servo assisted wireless gear changes too.
That just not cool!... I myself have a few Lowrider Bicycles andmaybe some interesting dangerious riggs....they are safe as long as the operator knows how to pilot them well and accknolege the engineering limits....Also I find it pretty bad a trend that people are shying away from eye catchers and exotics....The Sad and Boring type of Americans that are no longer willing to try bold things!
Everything else is deemed for clowns, mad scientists, and nuts!
@sanddragon99 You're talking drivel. If you want a bike designed for looks instead of function then go stick a sombrero on it. I personally don't care what you look like and I laugh at lowriders when they pedal past at walking pace. As an engineering project the hubless wheel is a dud. It's utterly pointless. Hardly works, costs a hundred times more, collects dirt and can't withstand impact. Go and pose somewhere you idiot. We still have a long way to go before beating the wheel as an invention
@sanddragon99 I have a compact recumbent with a 20"/16" wheel combo and a 3x7 rear hub (freewheel on an internal geared hub). You won't see those on the velodrome either, but it works really well for local commuting.
I'm sure that it sucks to not be able to win international events, but I don't race anyway.
the hubless wheel is a typical example of needlessly reinventing the wheel. It challenges a tried and and tested beautifully working system like the wheel and makes it heavier, more complex, open to dirt and basically useless. Even the front wheel on this bike is too small to bank safely into corners. A complete waste of time all round really.
Lower BB height (@2:00) makes for pedal strike on kerbs and in turns, doesn't it? Steering looks very twitchy. Like the out of the box thinking but don't think its going anywhere fast...
My Vespa that goes 75 mph. has 12-in tires. Yes the larger wheel covers more ground thus it goes faster, but only when you supply the power, and larger wheels makes it harder to climb hills which is a biggie in riding bikes. Your set-up would not climb hills well. Smaller wheels with low gears is how you climb hills. People who put electric motors on wheels have had that figured out a while now.
@dkw12002 Yeah, or big wheels with even lower gears. Wheel size makes no difference, you change the gearing to match, dummie. Bigger wheels are overall better, because they add stability, something neither your vespa or the bike in this video has much of.
@SpeedyCheeze Not true. If you have wheels that are too large and you attempt to compensate for this by very low gears, you get to a point quickly where the rpms you need to pedal becomes a problem and your bike slows down so much, that you lose stability when climbing hills. At that point, you are better off just walking the bike up the hill. 20' wheels are about ideal for hill climbing using pedal power and gears.
@dkw12002 gearing can be whatever you want. A bike with a 26in wheel at 2/1 ratio gearing and a bike with a 10in wheel at 5/1 gearing would both go 9mph at 60rpm at the pedals. If you changed to a "lower gear" of 1/1 for 26in and 5/2 for the 10in wheel you now go 4.5mph at the same 60rpm at pedals at the same difficulty. As long as the pedals aren't connected the the wheel directly, wheel size makes no difference.
@SpeedyCheeze By the time you got the gear ratio low enough to pedal that bike up a hill, the rpms your feet would have to pedal would be so high, and the bike moving so slowly that you would be better off walking it up a steep hill. That was my point. The limitation here is human pedal power. Of course, on the straight and downhill, the bigger wheels perform more efficiently and go faster. Again my point was HILLS, but then hills are a biggie around where I live in Texas Hill Country.
@dkw12002 If you need a gear so low that you have to pedal really fast it doesnt matter how big your wheel is. Since a small wheel as a smaller circumference, it has to rotate faster to match the speed of the big wheel. Look back to my example, you could scale the speed down but with the correct gearing the pedals would spin the same speed to push the big or small wheel to cover the same area. We are talking about bicycles with gears, or the bike in the video with compound gears, not a tricycle
Stay with it, hopefully one day youll be laughing all the way to the bank, and critical lameasses on here will still be on here in Mom's basement! Music does suck tho!
Worldusicrevolution you said it all, good work d00gal! It is something different and was well worth the build to find out if it could be done and to take it to where you have, this also lets you find out if it could be expanded or modified. I see that it has lots of room in the back hub for an electric motor and possibly batteries with a very low center of gravity, or for cargo. Would love to see it as a recumbent/electric sport version!
the weight of the bike is riding on the sprocket and the wheel is just rotating, it would monumentally fuck up if you were to jump a kerb or ride down some stairs..you could achieve the same thing with an overdriven small wheel the same size as the sprocket - sorry but crap
Fuckin sick man!!! I fool around with gadgets of the sort and i'd like to say that this is very promising! I mean its a prototype people need to get a life and accomplish something other than a youtube comment smh. Would love to know what they do in their spare time!
@thomasstunts his pedals are connected to the back wheel.. since the back wheel is the one moving the bike forward the size of the front wheel wont matter.... stupid ass!
Maybe it's the song, or the bike ride. But I don't know how this reminds me of when I used to live at my old house and go on bike rides with my friends from the same neighborhood. i fucking miss being a teenager. I'm 24 and loving it. But fuck I miss that shit.
Sweet. OK so I'm not an engineer but the first thing I would have done is to place the chain/cogwheel assembly upward and right under the rider and not so close to the ground where sticks, dirt and rocks would demolish these moving mechanical parts in short order.
if you had a front wheel that looked the same as the back one, but with the drive function, it would look like a really nice futuristic bike, and if the whole frame was made out of that flat metal.
form... semi-success..!! function FAIL..!! Twice the friction, waste of KW. You guys should try using your time more constructively...try trolling. Or maybe something you can handle, like a paper route.
hi dude, well i can give you a few good ideas, perhaps if you change the front wheel for one more bigger your project colud be look stupidless, and the second the back wheel could be close the star and from this way you don't use a chain o the breaks too like the olds bikes with the pedals think that bro cyaa, and good luck.............

@Hikikomori013 I love you Hiki - you're a real trier. I'll give you that. Erm hang on. No you get off and walk up hills. Alright skip the trying part. And no I don't take any pleasure from you face planting. I've had more knocks than a brothel's front door from cycling so I know what they are like. Fact remains this hubless thingy is complete poop. It is a technological dead end except for posing at low speed.
CompactJam 5 days ago
@CompactJam The disadvantage of the hubless wheel is the precision machining required and that they haven't developed the seals for extended use yet. It can be difficult to connect the drive. The technology is new and undeveloped.
The advantages are the larger diameter reducing side loads from the leverage of the wheel against the bearings and reduced weight and windage.
Whether the advantages outweigh the limits will have to wait until they're developed and in the market.
Hikikomori013 5 days ago
@Hikikomori013 No - there are only disadvantages and they are almost endless. The friction is a hundred times more, you have to disassemble the frame to change a tyre, they attract dirt, they weigh a hundred times more than a real wheel, any litter like a carrier bag feeding into it will kill it, any impact at all with break it because all shock is directed through the fragile drive system, they would always cost more - it's a technological DEAD END. Go and buy one and then tell me!!
CompactJam 4 days ago
@CompactJam Well, since you know more than the engineers who work on it I'll have to take your word on it, but 100 times? Is this as precise as your 12 chain claim? Do they really weigh 50 to 100 pounds?
But I agree that they are probably a dead end. Reactionaries won't touch anything noticably new. They'll make up all sorts of reasons why it must be bad and stick to antique technology until a professional racer rides it. They all want to pretend to be the racer dude.
Hikikomori013 3 days ago
@Hikikomori013 That's why my 400cc single cylinder scooter has no noticeable flywheel. Without a proper flywheel my low end torque is gone, it idles rough and I get poor gas mileage. But the racing bikes don't have the flywheel so they can shift faster at Laguna Seca.
I have an auto tranny. I don't shift, and I'm not going to race a scooter professionally. But racers have ultra light flywheels, so I have one, too. Fashion is more important than function on 2 wheelers.

@CompactJam I have good news for you. While the hubless has only been around since about 1990, and still hasn't been fully developed, it will still enter the market as a competitor, not a replacement. It will succeed or fail on its own merits, regardless of your hyperbolic attacks.
But you won't be forced to have one. You're safe.

@CompactJam Thank you far that lucid and rationally argued rebuttal. Let's pretend like you didn't have this outburst, shall we?
In the end it's just a technology. It works or it doesn't based on its own merits, and even if it doesn't work in the end it could start something that makes a real improvement in the technology you use now..
Even failures can lead to new successes.

@Hikikomori013 And yes I probably do know more than the engineers who entertained this waste of money because it's fairly obvious none of them have ever spent ten hours a day in the saddle or done roadside repairs.
CompactJam 2 days ago
@CompactJam Another advantage of the hubless wheel: Since the hub is almost the same size as the rim a single side rear end can be built with a fraction of the torsion load, so the rear tire can be changed without removing the wheel.
Sbarro uses them for his performance sport cars. He doesn't know they don't work.
I also like center-hub steering, although it doesn't look like the current race bikes.

@CompactJam I would like to hear your opinion on the CruzBike which is a recumbant with a front wheel drive. I have no recumbant experience but to me this solutions seems a lot more sensible?
nilo2209 6 days ago
@nilo2209 The CruzBike is not a true recumbent but a semi recumbant somewhat reminiscent of the eBike which failed due to breaking up. They have clearly sought to overcome some of the design problems I spoke about. A higher wheelbase and a shorter drive chain less prone to stretching. The front wheel drive will limit the turning arc a bit but generally they appear to have done a fair job of reducing weight. It is however a hybrid and will not give you the low profile advantages of a true rec.
CompactJam 6 days ago
@nilo2209 The advantages of it though are that you can use fairly standard equipment and parts. You will also be reasonably safe in traffic as others can see you. (I would still fix a long bouncy pendant flag though) On the downside it is still heavier than a road bike and you cannot climb out of the saddle on hills and 'ride the rivet.' The frame size appears to be very particular too as you can only adjust the leg length and not the saddle position or height.

@CompactJam thanks

@nilo2209 You're welcome sir. It's only my opinion based on about thirty years of cycling, including as a pro rider. But it is unbiased. I'm not shop staff trying to sell you anything and I don't work for any producer.
CompactJam 5 days ago
@nilo2209 The CruzBike is a regular mountain bike with a standard drive train mounted on the front fork, and swinging with the steering. There's even a conversion kit you can mount on your mountain bike.There's a steep learning curve, but anyone can develop the technique, then you can ride no-hands.
The compact long wheel base is another option. They're fairly small and easy to learn. The Sun EZ1 is a good machine.
Hikikomori013 5 days ago
@Hikikomori013 However commuter bikes still have evolved from racing technology although all cycling technology (except the materials) is basically of the nineteenth century. Drive chains and cables etc. tubular frames and cams. Even the old penny farthings were raced competitively back in the day. Derailluers are fragile which is why couriers ride single speed. The larger track guage chains make them even tougher. There are no servo assisted wireless gear changes too.

@sanddragon99 You're talking drivel. If you want a bike designed for looks instead of function then go stick a sombrero on it. I personally don't care what you look like and I laugh at lowriders when they pedal past at walking pace. As an engineering project the hubless wheel is a dud. It's utterly pointless. Hardly works, costs a hundred times more, collects dirt and can't withstand impact. Go and pose somewhere you idiot. We still have a long way to go before beating the wheel as an invention
CompactJam 1 week ago
@sanddragon99 I have a compact recumbent with a 20"/16" wheel combo and a 3x7 rear hub (freewheel on an internal geared hub). You won't see those on the velodrome either, but it works really well for local commuting.
I'm sure that it sucks to not be able to win international events, but I don't race anyway.
Hikikomori013 1 week ago
the hubless wheel is a typical example of needlessly reinventing the wheel. It challenges a tried and and tested beautifully working system like the wheel and makes it heavier, more complex, open to dirt and basically useless. Even the front wheel on this bike is too small to bank safely into corners. A complete waste of time all round really.

My Vespa that goes 75 mph. has 12-in tires. Yes the larger wheel covers more ground thus it goes faster, but only when you supply the power, and larger wheels makes it harder to climb hills which is a biggie in riding bikes. Your set-up would not climb hills well. Smaller wheels with low gears is how you climb hills. People who put electric motors on wheels have had that figured out a while now.
dkw12002 1 week ago
@dkw12002 Yeah, or big wheels with even lower gears. Wheel size makes no difference, you change the gearing to match, dummie. Bigger wheels are overall better, because they add stability, something neither your vespa or the bike in this video has much of.
SpeedyCheeze 1 week ago
@SpeedyCheeze Not true. If you have wheels that are too large and you attempt to compensate for this by very low gears, you get to a point quickly where the rpms you need to pedal becomes a problem and your bike slows down so much, that you lose stability when climbing hills. At that point, you are better off just walking the bike up the hill. 20' wheels are about ideal for hill climbing using pedal power and gears.
dkw12002 1 week ago
@dkw12002 gearing can be whatever you want. A bike with a 26in wheel at 2/1 ratio gearing and a bike with a 10in wheel at 5/1 gearing would both go 9mph at 60rpm at the pedals. If you changed to a "lower gear" of 1/1 for 26in and 5/2 for the 10in wheel you now go 4.5mph at the same 60rpm at pedals at the same difficulty. As long as the pedals aren't connected the the wheel directly, wheel size makes no difference.
SpeedyCheeze 1 week ago
@SpeedyCheeze By the time you got the gear ratio low enough to pedal that bike up a hill, the rpms your feet would have to pedal would be so high, and the bike moving so slowly that you would be better off walking it up a steep hill. That was my point. The limitation here is human pedal power. Of course, on the straight and downhill, the bigger wheels perform more efficiently and go faster. Again my point was HILLS, but then hills are a biggie around where I live in Texas Hill Country.
dkw12002 1 week ago
@dkw12002 If you need a gear so low that you have to pedal really fast it doesnt matter how big your wheel is. Since a small wheel as a smaller circumference, it has to rotate faster to match the speed of the big wheel. Look back to my example, you could scale the speed down but with the correct gearing the pedals would spin the same speed to push the big or small wheel to cover the same area. We are talking about bicycles with gears, or the bike in the video with compound gears, not a tricycle

Worldusicrevolution you said it all, good work d00gal! It is something different and was well worth the build to find out if it could be done and to take it to where you have, this also lets you find out if it could be expanded or modified. I see that it has lots of room in the back hub for an electric motor and possibly batteries with a very low center of gravity, or for cargo. Would love to see it as a recumbent/electric sport version!
