Green bike, wheel and generator thereof

Abstract

A green bike comprises a frame, two wheels, a first internal-gear module and a second internal-gear module and a transmission element. The frame has a pedal, a front supporting unit, a rear supporting unit, and a seat unit. The two wheels are attached to the front supporting unit and the rear supporting unit, respectively. The transmission element is disposed in the frame or a tube shield linking to the frame. The first internal-gear module and the second internal-gear module are coupled with the pedal and at least one of the wheels. The transmission element links the first and the second internal-gear modules for delivering power to the at least one of the wheels.

Description

technical field [0001] The invention relates to a bicycle, in particular to an environment-friendly bicycle that can achieve better environmental protection goals and reduce carbon emissions. Background technique [0002] A bicycle is a pedal-driven, manpower-driven or mixed-driven vehicle tool, which has two tires connected to a vehicle frame. Since the advent of bicycles, bicycles have experienced continuous improvement and progress. With the advent of modern materials and computer-aided design, bicycle innovation continues. Many commuter or city bikes (eg US or European city bikes) are equipped with a 15 to 21 stage external gear module including sprockets and derailleurs which require relatively expensive and complicated regular maintenance. However, when considering future environmental technologies, many disadvantages still exist in the current manufacturing process of bicycles. In view of the global trend of "the greener the better" value, many new and creative bic...

AI Technical Summary

Problems solved by technology

[0010] In the above patent, an electric motor must be installed on a frame of a bicycle, and the electric motor is coupled to a wheel through a gear or a transmission, which will result in high cost and increased weight

In addition, although the electric motor can be installed in the hub of the bicycle, the spokes of the bicycle must be re-fixed to the hub one by one to rejoin, resulting in a lot of time required for assembly

Thus, the aforementioned motors are bulky, have low range and are not convenient for commuter, urban or outdoor riding applications
