Conquer Any Terrain: Unleash Power and Range with the Ultimate Fat-Tire E-Bike
The 500W motor (up to 860W at peak) helps you climb hills easily and reach speeds of 15.5 mph (25 kph), with the ability to go up to 25 mph (40 kph) when unlocked.
Big 20” × 4.0” tyres easily handle city streets, beach sand, snow, mud, and forest paths, giving you grip and control wherever you ride.

The colour screen shows your speed, battery life, and distance, plus lets you choose from 5 different power levels to match how you want to ride.
Double the Power, Double the Fun: Two Battery System
The Fafrees FF20 Polar comes with two 48V 10.4Ah batteries that work together or separately. One fits inside the frame, while the other sits on the down tube. You can use just one battery for shorter trips or for long adventures.
The special battery system spreads out the power use, making the batteries last longer overall. The strong 500W motor helps you climb hills with a 25-degree slope without breaking a sweat and gives you smooth power.




Total Comfort: Built for All-Day Riding
Riding the Fafrees FF20 Polar feels good even on rough ground. The front suspension fork (40 mm travel) works with the fat tyres to soak up bumps and holes in the road. The wide, cushioned seat keeps you comfortable even on long rides.
The bike has strong disc brakes front and back with 160mm rotors that stop you quickly and safely, even on loose dirt or gravel. The bright colour display is easy to read in the sunlight and shows you everything you need to know while riding. You can also use the walk assist mode when you push the bike alongside you.
Easy to Use, Easy to Store
The Fafrees FF20 Polar is built from strong aluminium but weighs 75 lbs (34 kg), making it manageable compared to many electric bikes. It can carry riders up to 330 lbs (150 kg) without any problem.
The step-through frame makes getting on and off easy, even if you have trouble lifting your leg high. Riders from 5'3” to 6'5” (160-195 cm) can use this bike comfortably. When you need to put it in your car or store it at home, the bike folds quickly to save space.
You can change between full electric power (using just the throttle), pedal assist (where the motor helps while you pedal), or regular biking mode whenever you want.




Seven Speeds, Total Control
The Fafrees FF20 Polar comes with a 7-speed Shimano gear system that lets you find the perfect assistance level for any situation. On flat ground, you can shift to a higher gear for speed. When climbing hills, shift to a lower gear for easier pedalling.
Combined with the five levels of electric assist, you have complete control over how much work you do and how much the motor helps. The twist throttle gives you instant power when you need it, perfect for starting from a stop or getting a quick boost without changing gears.
All-Weather Ready: Ride Rain or Shine
The Fafrees FF20 Polar is built to handle all kinds of weather. The electrical components are protected against rain and splashes, while the mechanical parts are designed to work reliably in both hot and cold conditions (-10°C to 45°C).
The bright LED headlight helps you see and be seen in the dark or bad weather. The fat tyres provide excellent grip even on wet surfaces, giving you the confidence to ride year-round. The fenders keep mud and water away from splashing on you.
