A Rohloff Speedhub hub gear A Shimano XT rear derailleur on a mountain bike A bicycle gearbox with chain tensioner. Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns.
Given this simplified equation, one can calculate some values of interest. For example, assuming no wind, one gets the following results for power delivered to the pedals (watts): 175 W for a 90 kg bike + rider to go 9 m/s (32 km/h or 20 mph) on the flat (76% of effort to overcome aerodynamic drag), or 2.6 m/s (9.4 km/h or 5.8 mph) on a 7% ...
Another reason ebikes are popular is the low cost to charge, such as this e-bike which costs 10 cents to charge and able to provide 30 miles of range at 20 MPH. E-bike usage worldwide has experienced rapid growth since 1998. [27] China is the world's leading producer of e-bikes.

Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very high or heavy gearing around 125 gear inches (10 m). As in a car, low gearing is for going up hills and high gearing is for going fast.
Bike geometry parameters: wheelbase, steering axis angle, fork offset, and trail Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration.
