My moped uses bicycle forks and wheels. It has a 4 speed Honda motor, so you know it is plenty fast.
I have 2400 miles on it with no trouble.
I have a 48 spoke rear wheel laced cross 3 only because I was too lazy to make cross 4 spokes for it. The 48 spoke wheel is 33 % stronger than a 36 hole wheel. I like Alex DM24 wheels. I recently found Alex DX32 rims. They are 32 mm wide and fit 2.75x16 or 3.25x16 tires.
The forks are Downhill bicycle. They are much better than ANY moped forks I have ever seen.
