twion – push boundaries

In today‘s world, one thing matters more than anything: mobility. Therefore, we want transporting devices that are adapted  to this dynamic lifestyle: efficient, smart and fun to drive.

With twion it is possible to expand possibilities and to reach the highest level of independence. The state of the art electric motors equipped with the most modern software and electronics and provide enough extra power with each push on the rim to comfortably overcome longer stretches or to easily surmount slopes. The driving  sensor, positioned on the push rim, continuously and precisely determines the correct amount of assistance. This way the wheelchair driver remains active while comfortably reaching the desired destination.

Feel the speed – faster and further than ever before

Modern lithium batteries in the wheel hubs provide the twion with sufficient energy to push your driving speed up to 10 km/h and to reach longer distances without strain. This way you can enjoy maximum flexibility in every day life.


“Going up and down slopes is lots of fun, even when they are steep.”

Martin S. from Stuttgart
