The Lightweight Vivax Assist Bicycle Motor Kit Gives Your Bike a Secret Boost

This bicycle motor kit allows you to have a tiny and secretive electric motor on your bike. The Vivax Assist 4 lb motor is so small, no one will be able to see it as you whiz by them. The lightweight device retrofits into a bicycle's seat post.

Manufactured by Gruber Antrieb GmbH & Co. in Austria, the Vivax Assist makes the bike you already own look better and helps with stability. The battery can hang under the seat, in a saddlebag or in an option that looks like a normal water bottle attached to the frame. A hidden button on the handlebars turns the motor on and off, making the bicycle motor kit even more discrete.

This product is intended for experienced riders looking for a smaller boost than a standard e-bike.
