Selling because the child received a cross bike as a gift.

Advantages:
Torque Sensor (Torque Sensor Mivice S200) – the motor reacts to how hard you pedal. The ride is much more natural, smoother, and easier to control.
High torque – about 50 Nm. Although the nominal power is only 250 W, the bike has good traction on inclines and when starting from a standstill.
Hydraulic disc brakes – better and more precise braking than the mechanical brakes of the older M1 Pro version.
Newer electronics and control system – smoother motor power delivery.
More efficient energy use – the 250 W system combined with the torque sensor can use the battery more economically.
EU specification – factory 250 W nominal rating and 25 km/h pedal assist limit adapted for the European market.
Modern riding feel – instead of the simple "I pedal, the motor turns on" principle, the assistance adjusts proportionally to your pedaling force.

Why the new 250 W version is better than the 500 W
The most important difference is the Torque Sensor. The new 250 W version uses the Mivice S200 torque sensor, so the assistance changes depending on how much force is applied to the pedals. The 500 W version, which Fiido currently sells in some other markets, specifies a simpler 12-magnet speed sensor.
