Folding E-Bike 20" (Possibly Smaller) With A Modular Power System

Good evening,

The owner of the company operates Crashproof Solutions, LLC, which is a technology company, for 6 years. The company was started on 2/12/2002.

This is a wish list generated by a market study with potential customers. We do not want to reinvent the wheel and would like to work with a manufacturer who has a similar model in production ready for US safety certification.

We are prepared to become the #1 distributor in USA.

Sincerely,

Leonid S. Knyshov, CEO
