Editing Electric generator (section)

====Bicycles====
Bicycles require energy to power running lights and other equipment. There are two common kinds of generator in use on bicycles: [[bottle dynamo]]s which engage the bicycle's tire on an as-needed basis, and [[hub dynamo]]s which are directly attached to the bicycle's drive train. The name is conventional as they are small permanent-magnet alternators, not self-excited DC machines as are [[dynamo]]s. Some [[electric bicycles]] are capable of [[regenerative braking]], where the drive motor is used as a generator to recover some energy during braking.
