With vivax's 2-in-1 principle all kinds of training in any type of terrain is possible. One Bicycle - two functions. Means you can easily mix active sports cycling with assited riding. The basic function of the bicycle remains because of the low weight and the perfect position of the motor in the seat tube. No limits, and training is fun!
The lighweight seat tube motor balances out the performance difference between riding partners in a way other systems can't. With the E-Mountainbike you maintain an authentic feeling ride and longer day rides are possible. Weighing only 1.8 kg (including battery) it is the world's lightest E-Bike kit.
