The Fiido M21 Pro is an improved version of the powerful Fiido M1 Pro fat tyre folding e-bike. It has a new torque sensor for perfectly smooth pedal assistance. This enables more precise and natural control of the motor power. The M21 is powered by a strong 500W motor paired with a 7-speed gear set. It can reach speeds of up to 25mph and is capable of taking on any terrain. The 20x4inch wheels have ultra-wide rims with all-terrain fat tires.

The M21 has full suspension for a smooth riding experience whether on a dirt track or a rocky trail. The removable 48V battery of this bike enables rapid acceleration and a maximum range of 80miles on a single charge (in pedal-assist mode). This means you can ride long distances without worrying about the battery level. A full charge from empty takes 9 hours.

Free Mudguards Included
