This prototype chainless bike may be the future of cycling

CeramicSpeed Driven Chainless Bike Drive

The future of cycling may just have been revealed at Eurobike, an annual cycling trade show that is taking place right now in Germany. At the event, a company called CeramicSpeed took the wraps off a prototype bike that looks like something straight out of a science-fiction movie, complete with a revolutionary new chainless drive system that promises to be a revelation for riders, improving speed and efficiency without an increase in power.

CeramicSpeed developed its new DrivEn system in conjunction with the University of Colorado’s mechanical engineering department. The innovative crankset does away with the traditional chain drive, replacing it with a system that uses 21 ceramic bearings to transfer power generated from the pedals through front- and rear-mounted pinions instead. This cuts down on the number of moving parts involved with the drivetrain considerably.

All the torque appears to be on one individual sprocket tooth. On a chain drive the torque is shared with many more sprocket teeth.

   I still have this, @truth_seeker  Raleigh Super Course, 1968. It's to uncomfortable for this old man to ride anymore. So I stole some dark skinned person's mountain bike in Houston a few years ago. (He was trying to break into my van).

@corbe
Very little difference at all, from mine, design and equipment-wise .

Wow! The stupid Germans invented shaft drive technology from 1899! Geniuses!

   My last Motorbike, the Yamaha Virago 920 had shaft drive, it sucked too.
