Alt Bike Culture - What is this called???

I saw this on craigslist today...

289471

Anyone know what those are called, how they work, or what they are worth? I've never seen anything like it... but then again, I haven't seen everything...

'Preciate it.

It looks like homemade 4-wheel scooters? Can't tell much from the picture.

A normal bicycle wheel is made to be supported from both sides. If you make a 4-wheeler using those wheels and axles, you'll need some kind of support on both sides if it's homemade- and that's the bars that loop over the wheels. If it was factory-made, they'd have a stronger axle and just support it from one side.

My guess: Someone lived next to a long hill and made these up so the kids could coast down it.

Looks kinda like theyre designed to flex torsionally to steer.

Sorry I am so late hopefully you look here now and then :) It is made by the guy that own Quadcoaster He makes many models of 4W push scooters some with Electric Motor Here a link to his Youtube channel http://www.youtube.com/watch?v=oAvXD4sci04&list=UUFDTrVT88UMskws-8FMAppA http://www.youtube.com/user/Quadcoaster?feature=watch The old ones had a very odd steering but maybe the most recent ones are more conventional.

Very cool, Weakling, thanks for hunting that up!

Cool, I'd totally go for one with a little motor... thanks for the info!
