Since shaft-drives require gear hubs for shifting, they gain the benefit that gears can be shifted while the bicycle is at a complete stop or moving in reverse, but internal hub geared bikes typically have a more restricted gear range than comparable derailleur-equipped bikes. A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel.

Maria Dermentzi 4 months ago. Well, if this isn’t the most gratifying thing Looks a bit tricky for getting close ratio gearing.
A fundamental issue with bicycle shaft-drive systems is the requirement to transmit the torque of the rider through bevel gears with much smaller radii than typical bicycle sprockets.

Hopefully Ted Cruz stays off Twitter today 1 shares Nov 07, CeramicSpeed has unveiled a prototype of a chainless bike. Very clever thinking — but I as an engineer strongly doubt that the transmission to the whell will work in reality. Most of the advantages bucycle for a shaft drive can be realized by using a fully enclosed chain case. The drive shaft is often mated to a hub gear which is an internal gear system housed inside the rear hub.
Admittedly, it’s not really solving any major problems with the current way chain drive systems work on a bicycle — having to constantly clean and lubricate — chajnless dang, it looks cool.
