This article is a supplement to All About Your Belt, the main resource for all belt-related topics. In this article, we explain how to adjust the belt on the Roadsterdster V2 with the removable lollypop-style tensioners. If you have a different version please refer to the links below. As with all ebikes, pay special attention when working around the rear wheel not to damage the motor cable exiting the hub. Damage done to this cable by the rider is not covered under warranty.

Gravel Edition Single bolt Dropout Adjustment

Gravel Edition Two bolt Dropout Adjustment


Tools Required

  • 4mm allen wrench
  • 18mm wrench 

Getting Started

  1. Disconnect the motor cable and cut only the zip tie(s) nearest the motor. 
    • Note: the zip ties in front of the plug should stay on. Verify they are preventing the cable from touching the crank wheel and the tire of the bike. 
  2. Carefully loosen the 18mm axle nuts on either side of the rear wheel. Be careful not to damage when doing this. 
  3. Remove the nuts far enough that the torque spacers/washer and their tab can slide away from the frame.
  4. Adjust the 4mm tensioner bolts evenly on both sides to adjust the belt tension as described in All About Your Belt
  5. Tighten the Axle nuts to 60Nm when done.

Removing the Rear Wheel

  1. Follow steps 1-3 above
  2. Completely back off the two 4mm adjusters
  3. Slide the wheel/axle forward in the dropouts. 
  4. Now the belt can be lifted off the rear wheel cog and set on top of the belt on the frame above the rear wheel. 
  5. Open the brake caliper using the small lever located where the cable enters the brake caliper. By flipping the small black lever up it will separate the brake pads and allow the wheel to pass through. Depending on how tight the brakes are adjusted, the tire may have to be slightly or completely deflated to achieve this.
  6. Remove the rear wheel by sliding it backward out of the dropouts. The axle has two flat sides on it. Important: note the orientation of these flats for easy reinstallation.
  7. Tighten the Axle nuts to 60Nm when done.

How to Change the Belt

To replace a belt, follow the steps above to loosen the belt and then: 

  1. Loosen both 5mm frame bolts and remove the bolt and backing nut. 
  2. Spread the frame with your fingers and thumb as shown to remove the belt. This step is easier with the wheel removed.
  3. Insert a new belt into the frame, and reinstall 5mm frame bolts and backers. Tighten to 10Nm
  4. Reinstall the rear wheel.  
  5. Establish proper tension using techniques demonstrated in All About Your Belt
  6. Tighten the Axle nuts to 60Nm when done.
