Inverted-tooth-type-chain cycle with adjustable saddle

摘要

Field: mechanics, transport. In a conventional cycle, the force is only fully utilised if the pedal lever is horizontal. In the inverted-tooth-type-chain cycle, on the one hand, unused forces acting counter to the pedal axle are avoided and on the other hand the weight of the leg is utilised. Together with the up-hill saddle, it is superior to a conventional cycle by virtue of the performance and even more so when going up hills.
