Default Drive Roller: Noob Help

I just finished my motorized bike (electric) recently, and the drive roller I used was a polyurethane skateboard wheel with the steel nut epoxied in with 2 part epoxy, the nut came with the motor (reversed threads).

Anyway the bike worked outstanding (20.2 mph tops). But sadly the epoxy started to give away and the wheel was barely hanging on.

So, I am just asking if someone can direct me to a site with well made (cheap) drive rollers, preferably metal with deep grooves so it won’t slip in wet conditions.

Here are the specks of my motor axel,
Total shaft length - 1" (back 1/2" circular, and front 1/2" reversed threaded w/ flat side)
Shaft diameter- 1/4"
Skateboard wheel diameter - 2 1/8"

***I cannot go any larger or smaller with the roller diameter… the motor is not adjustable.***(presure of the roller on the tire is just perfect)
