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 right over the rear wheel and the bike has a low profile, allowing the rider to position themselves like they would on a motorbike.
