The Boar’s aluminum frame has been completely custom designed in Canada by Surface 604. It’s been designed for maximum stiffness and minimum weight with clean, sexy lines. Most importantly, we’ve placed the battery (discreetly) in the down tube, keeping the centre of gravity low – lower than any other fat e-bike on the market. Add to that the short wheelbase and you’ve got an electric fat bike that rides like a Ducati motorcycle.

Equipped with Bafang’s next generation geared hub motor 350w. These new motors are incredibly silent compared with anything else on the market, weigh less and are so low-profile it’s hard to tell it’s electric. Geared hub motors have the advantage over direct drive motors in that they deliver high torque and are resistant to overheating when running at lower RPM’s. This is well-suited to carrying heavy loads up hills at slower speeds.

Comes standard with a SRAM 10 speed transmission (also known as a “1 x 10”), providing ample range of gearing by one of the most respected names in bike components. The 1 x 10 transmission requires no front derailleur, making shifting even more simple and also eliminating the left hand shifter. The result is a cleaner looking handlebar that provides all the gearing a rider needs for steep hills.

Power delivery to the motor is regulated by a torque sensor in the dropout hanger that senses how much torque you apply to the pedals; the harder you pedal, the more power the electric motor provides. The result is smooth power delivery and a natural ride much like a regular bike. The torque sensor has the added benefit of acting like a Battery Management System (BMS). The power going to the motor is instantly reduced when you reduce the torque and turns off completely when you stop pedalling. The effect is greatly reduced power consumption, longer range and longer battery life.

The Boar has been designed to be compatible with some fat tire suspension forks (RST and RockShox) for increased comfort and improved traction and handling in rough
