A bicycle has multiple electrical devices and a front and rear wheel assembly, each having a fork with two tines and a wheel with an inner support structure. Moreover, at least one generator is mounted on the wheel assemblies. Each generator has multiple coil devices and multiple permanent magnets. The coil devices are mounted on the tines of at least one fork. The permanent magnets are mounted on the inner support structure of at least one wheel, correspond to and align with the coil devices and generate an electrical current in the coil devices when the wheel rotate. Since no frictional forces are required to drive the generator, the efficiency is higher, and the operation of the bicycle does not interfered by the generator.
