Step 8Gears, Sprockets
This step can a little tricky. You need to calculate some things to try and determine the best arrangement of teeth on the two sprockets - one on the motor (the Drive sprocket) and one on the rear wheel (the Driven sprocket). The performance of the bike will be greatly affected by slight differences in gear-teeth number, so we used a gear calculator, like this great one provided by Make Magazine.
