The Fafrees FF20 Polar Dual Battery Electric Bike is a folding fat-tyre e-bike with a 48V dual-battery system, 500W rear hub motor and 20×4.0-inch tyres.
With approximately 998Wh total battery capacity, 65Nm of torque, front suspension and Shimano 7-speed gearing, the FF20 Polar is built for extended leisure rides, commuting and mixed terrain where range matters.
UK road-use note: This configuration exceeds the standard UK EAPC 250W continuous-power limit. Public-road use is subject to applicable vehicle approval, registration, tax, insurance, licensing and motorcycle-helmet requirements.
Range and performance figures are manufacturer estimates. Actual results vary with rider weight, terrain, weather, tyre pressure, load and assistance level.

Check rider measurements and sizing before you order.
Fit guidance: Folding step-through frame with a low 42 cm standover.
Sizes are a guide. Rider proportions, footwear and setup can affect fit.
Despite its substantial 20 × 4.0-inch tyres and 35 kg weight, both the main frame and handlebars fold. This makes storage and vehicle transport easier than with a fixed-frame high-speed fat bike.
FAFREES classifies the Polar HS as an EU L1e-B type-approved vehicle, capable of speeds up to 45 km/h rather than the 25 km/h limit of a standard pedelec.
The FF20 Polar HS uses a dual-battery configuration totalling 24Ah or 26.8Ah, providing up to 1152Wh or 1286.4Wh of energy and a manufacturer-listed range extending as high as 130 km depending on version.
