This Fat Tire Bike is designed to get you through any condition whether it's snow, sand or even the mud. When creating this monster Surface604 decided to connect with some of the best manufacturers in the industry and design a topend product with a valuable price for consumers.

  • Low-Profile Battery Placement, Boar's aluminum has been completed customized and designed  for maximum stiffness and minimum weight with clean lines. A ­36V 13.3Ah / 478Wh Samsung Lithium Ion in-frame battery integrated into the downtube for a low center of gravity and sleek look. This with the short wheelbase allows for an fat bike that will rides like a Ducati motorcycle. 
  • An Ultra-quiet, High Torque Bafang Geared Hub Motor (350w). Users will get a next gen geared hub motor 350w that's incredibly silent, weighs less and if so low profile then anything on the market that you won't know it electric! This motor has high torque which makes it resistant to overheating when running at lower RPM's.
  • The Torque Sensing Battery Management System (BMS) will apply pressure on the pedals to give you more power when you want it and less when you just need more of a natural ride. The power going to the motor is instantly reduced when you reduce the torque and turns off completty when you stop pedaling. This alllows for increased battery range and life.
  • SRAM’s 1x10 transmission requiries no front derailleur, allowing for simplified shifting, a cleaner looking handlebar and great gearing for a rider.
  • Tektro hydraulic disc brakes allows for users to be safe with the stopping power and safety needed, even when carrying heavy loads. It performs well in temperatures down to -25 C (-15 F), users will be prepared even in the winter. 
  • RST and RockShox suspension fork compatibility making any trail accessible.
