Step 7The chain and finishing touches
Chain:
Once everything is together the chain can be broken down and sized to fit. Chain tension is very important or the chain pops off whenever you try to turn.
This was the most difficult part of the whole project. A lot of trial and error was used to get the tension correct. I tried several ways to keep the tension even including using springs and rollers but in the end found it was easiest to just keep the chain short and tight.
When measuring the chain to take out links you have to stand on the deck because the weight of the rider pushes down on the support bar and moves the motor closer to the sprocket.
Finishing up:
I used zip ties to keep all of the wires neat and put the battery wires inside the Velcro for the foot strap to keep everything out of the way. I also put a furniture cap on the end of the support bar to cover the sharp edges.
