The Fafrees F20 Max Folding Fat Tyre Electric Bike pairs a 48V 22.5Ah Samsung battery with a 500W rear hub motor and wide 20×4.0-inch tyres for long-distance, mixed-surface riding.
Its folding frame, CST fat tyres, front suspension and Shimano 7-speed drivetrain make the F20 Max a strong choice for riders who want extra battery capacity and fat-tyre stability in a portable format.
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.
