Gravity Bike

"This Gravity Bike built by Jeff Tiedeken can reach high speeds when going downhill due to its lightweight design and lack of features like a chain and pedals. The seat is fitted over the rear wheel, and the bike has a low profile, allowing the rider to position themselves like they would on a motorbike.

The minimalistic design features elegant curves, 26-inch Crossmax Lefty wheels, Avid Elixr hydraulic disc brakes and motorbike-style footpeg struts. The bike has reached speeds of 50 mph and is said to have the potential to achieve up to 70 mph.” - PSFK
