ABSTRACT:
A battery and generator operated electro-mechanical device looks like an engine and emits engine sounds. The engine attaches to a bicycle frame giving the bicycle the appearance of being a motor bike. The engine makes an authentic idle sound when first started up and sounds like an engine accelerating to full throttle as the bike is pedalled. In a second embodiment, a fully mechanical engine sound is produced whenever the bike is in motion. Both embodiments are housed in an authentic looking engine housing.
