Two 1344Wh batteries set the Frey EX FAT apart from Frey's other fat tire builds, extending range for hunting, fishing, and multi-day trips into the backcountry. A Bafang M620 motor and full suspension carry that range across rugged, unpredictable terrain.
At the heart of the EX FAT is a Bafang M620 mid-drive motor system with 160Nm of torque, paired with a dual 48V 28Ah (1344Wh) battery setup for extended range, plus its own throttle for added riding control alongside ECO and SPORT pedal-assist modes and a 6km/h walk mode. The inverted fat bike air suspension fork and RockShox Monarch air suspension rear shock with 140-150mm of front and rear travel work together to absorb impact and keep the ride smooth and controlled over rough, technical ground.
Built on a 6061 alloy fat bike frame with trail geometry and full bearings, the EX FAT rolls on 26" double-wall alloy rims fitted with 26" x 4.8" fat tires for traction and float across snow, sand, and mud. Tektro HD E730 4-piston hydraulic disc brakes with 203/203mm rotors provide confident, reliable stopping power, and the Shimano Alivio 9-speed drivetrain ensures smooth, dependable shifting across variable terrain.
Available in Black and Army Green. Sizes M, L, XL.
