The Topstone Neo SL is a pedal-assisted gravel bicycle equipped with a Mahle X35 EBikeMotion motor and an integrated 250 Wh battery.

The fact of having a hub motor, equipped with a torque sensor*, allows for pedaling as free from friction as possible.

Therefore you will not feel the engine cutting above 25 km/h and you will use the engine assistance mostly uphill.

For this reason it is still possible to have a greater autonomy (even by many km) than 80 km despite having an integrated 250 Wh battery.

The bicycle is also lighter than the parallel model with the central engine.

*The torque sensor has the task of sensing the cyclist's effort and transmitting to the control unit how much power to deliver.
