On private routes, the maximum speed limit can be unlocked and it is even possible to exceed 45 km/h depending on the transmission ratio used.

The engine mounts crowns with a standard 5-hole pitch with a 110 mm bolt circle, this allows the user to easily replace the crown, it is in fact possible to mount a 34-tooth crown up to a 52-tooth one. In the particular case of installation on a bike used for very steep climbs, it is even possible to mount a 26-tooth chainring (applied directly to the engine). The crown supplied with this motor is 42 teeth if a different crown is required please contact us.

Thanks to the latest generation torque technology, the motor works intelligently following the user's pedalling, the pressure sensor modulates the force applied to the pedal and multiplies it at the transmission output with variable intensity based on the level of assistance selected.

The motor is easy to install, it does not need brake levers with motor detachment sensor as the torque system interrupts the assistance simply by not pressing the pedal, allowing for an optimal feeling with the user.
