Help with wheel pully ratio.

Hello
I have evolve wheels 97mm and 15 tooth motor drive pulley,
Will 36 tooth pully wheels be OK, been told 32 is best but dickio only sells 36. Comes out to 29mph, which is fine not interested in breaking land speed record.
Thanks

Can you give us more details about your build? Particularly the motors and the discharge of your battery?

Sorry 12s9p battery so plenty of current available, and 190kv motors

If most of your commute is in an urban environment, then go for the 32. Otherwise I’d strongly recommend the 36 if not higher

As a general rule, always go with the larger wheel pulley. Reasons:

  • it’s easy to increase the motor pulley size if it’s got too much torque, but hard to do the opposite
  • it’s more likely people move to a bigger wheel size later as opposed to a smaller one

If you don’t like it, increase the motor pulley teeth later. That’s easier and cheaper than finding new wheel pulleys.

Can I ask what battery type
30q

well i have 1 44t pulley wheel ordered by mistake, didnt really know what i was ordering, should i order up another 44t pulley wheel, and play about with the motor pully wheels?

a 15 tooth motor wheel and 44t pulley wheel gives 26 mph plenty and probly lots of tourque.

and order up 2, 23 tooth motor wheels for later ?

I’m using 36T pulleys with 97mm wheels and they work fine,
like @b264 said it’s easier to play with the ratios with bigger wheel pulleys.
I’d go for 36T/40T pulleys for 97mm wheels and 40T/44T for 110mm.
