What's the need for 2 torque arms?
My bike is made of aluminum, and this is a soft metal when compared to a steel axle. If I did not use a torque arm, the nut that tightens down the axle could become loose due to the torque of the motor, thus causing the axle (not the wheel) to spin within the dropout and grinding the surrounding aluminum dropout--this scenario would be a disaster for several reasons:
1. The motor's wiring could be destroyed from the spinning of the axle
2. The exposed wiring could short out the controller
3. While you're riding, you could fall to the ground when the rear wheel separates from your bike
4. The dropout would be destroyed rendering your frame useless
What does a torque arm do?
The torque arm locks the axle in place, so that it cannot spin within the dropout. It is usually a thick piece of steel that is drilled to perfectly fit the axle and attaches to another point of contact to prevent the axle from spinning within the dropout.
Modified Crystalyte Torque Arms
My bike has a recessed rear dropout, so the original arms would not fit. I modified two Crystalyte Torque Arms for each side of my bike. I wanted to use a preexisting screw hole to secure the torque arm, so all I had to do was cut the torque arm until it fit in the recessed area and drill a hole to fit a screw. This method worked for me because the rear dropout was flat and had an existing screw hole.
Tools used:
Drill
Dremel
Vice
Cardboard (to mockup the cut)
