Pedal assist is a technology that uses multiple sensors to intelligently engage (and disengage) the electric drive system based upon rider preferences and tendencies, all with an overriding factor of rider safety.

For your McQueen 750, the main sensor that communicates between the rider and the controller/motor is called a cadence sensor. It is mounted in the bottom bracket and is a 12 magnet sensor. A cadence sensor does just what it sounds like it does, it measures the rider’s pedaling cadence and communicates the pedaling speed to the controller. The controller, in turn, draws power from the battery and sends it to the motor based upon how much power is necessary to compliment the cadence being applied by the rider. The rider determines what level of power he/she wants to be utilized via the up and down buttons on the left handlebar. When pedaling slow the motor will produce more power and as the rider pedals more, less power is supplied from the motor.

When you first start pedaling it will take approximately 1/2 rotation of the pedals before the system engages. For this reason many people start motion with the throttle, then begin pedaling to ensure smooth transition. We suggest starting on pedal assist level 1 and adjusting up from there depending on your desired speed and incline.

Just as the motor engages when you begin pedaling, it will disengage when you stop pedaling. If you start pedaling again it will kick back in.

As a safety precaution, your hydraulic brake system is outfitted with two state of the art motor inhibitor sensors, which signal the controller to immediately disengage power to the motor when the brake lever is depressed. Any time you are uncomfortable with the speed just lightly tap the brake and it will disengage the motor immediately. Brake as you would normally brake if you want to stop or slow down.


  • Start motion with the bike in first gear, gently using the throttle to propel you forward

  • Pedal assist will kick in after 1/2 rotation of the pedals

  • Increase the pedal assist level depending on the incline and speed desired

  • GEARING, GEARING, GEARING!!! - Start off in a low gear and use your right thumb to increase gear just like riding a traditional bike. Always climb hills in a low gear, first or second, shifting up as you gain momentum.

  • Feather the brakes to stop power to the motor; To stop or slow down, brake normally

  • As you gain comfort with the bike, be more aggressive with shifting, pedal assist levels, throttling, and braking

  • Always remember - The motor is on the bike to help the rider, not replace the rider.
