Designed by aircraft engineer Jim Bede, the vehicle initially was known as the Litestar Autocycle, but the the name changed to Pulse Autocycle after Bede sold out to the Owosso Motor Car Company. Owosso built the vehicles from 1984 to 1990. A few hundred are said to have been built.
The rocket-shaped fiberglass body is built around motorcycle mechanicals. Yamaha 400cc and Honda 450cc engines were commonly used.

The two-seat tandem interior is accessed via a sliding canopy. It's equipped with a stereo and air-conditioning.
