Abstract: A telescoping bicycle handlebar assembly is disclosed wherein a crossbar adapted to provide support for a rider's hands during a bicycle ride is attached to a downbar extending substantially perpendicularly therefrom. A hollow tube adjacent to the front wheel of the bicycle and displaced from the bicycle's centerline is adapted to receive various lengths of the downbar depending on the height at which the handlebars are to be placed. A securing device is attached to the hollow tube and adapted to selectively secure the downbar in place inside the tube.

Abstract: A unidirectional rotating assembly, a bicycle powering mechanism, and a bicycle using the same are disclosed. The unidirectional rotating assembly allows a chainring to rotate while the crank and axle remains still. The bicycling powering mechanism combines the unidirectional rotating assembly with a powering device. The powering device is coupled to the unidirectional rotating assembly through a drive ring. This allows the powering device to drive the unidirectional assembly, thereby driving the chainring. When the bicycling power mechanism is part of a bike, the chainring is connected to the rear wheel of the bike through a chain and rear sprockets. Because of this, the bicycling powering mechanism can propel the bike while the cranks are stationary. Additionally, a person using a bike having this configuration is still able to shift gears. Thus, the bicycling power mechanism need not be designed with gearing.
