The Sport-tuned vivax assist can't really be compared with traditional electric bikes or pedelecs. It represents a completely new kind of drive. Unlike front and rear hub motors and mid-mounted motors, the vivax assist drive fits neatly inside the seat tube and adds very little extra weight. It also appeals to a new target group, bridging the gap between the sports bicycle and the electric bike.
No other motor combines the ability of sports cycling with the convenience of motorised support as well as the new vivax assist. Elegantly hidden in the seat tube, it produces considerable extra power to the crank, up to a maximum of 200 watts, at the mere touch of a button. Switching "on" and "off" while riding is easy. When the motor is off, the bike works normally and without any extra resistance. Thanks to its retrofit nature, it will fit a huge variety of bicycle brands.
