Bicycle dynamo device with tachometer similar components, comprises a follower that is rotated by bicycle wheel spokes to energize a dynamo and generate power

摘要

Bicycle dynamo device has a rotating drive wheel (11) with an integral follower (12) that is placed between two wheel spokes (13) of a bicycle wheel (1) so that it drives a drive wheel (14) with a flexible shaft (3) that is connected to a dynamo (4) for power production.
