VIVAX Assist System

The lightest electric bike motor system on the market!

Lightweight & barely visible.
The auxiliary drive retains the look and almost the weight of your bike.

This system is unique. This system retains the authentic riding feel and technical characteristics of a high-quality bike.
Your training performance is increased or boosted as the e-assist is only switched on when required, e.g. on a steep climb.

We maintain the joy of non-motorised cycling for you and provide invisible, clever e-assistance from time to time, if necessary.

The basic structure always consists of

Motor gear unit
Pinion mounting sleeve
Freewheel unit
Battery with saddlebag and charger
Analogue button (1-stage)
Speed sensor
Fastening material (screws, ...)
Installation is only possible via a specialist workshop with special tools and a suitable basic bike.
