Hello all,

I have just picked up a new onroad toy, and i need to find out what pinion gear i need. It currently has an 84t 48p spur, and i want to marry it up to my 7700Kv motor.

Im not planning on racing it, or anything like that, just want it to cruise down the road, but still be able to handle it if i give it full throttle!

I know absolutely jack about electrics btw.


Thanks

A good starting point is the old 4:1 ratio....84/21 will be a good starting point....temps will help with the rest

7700kv is going to push hard....take a GoPro with you....

It was wrongly supplied by castle, it was supposed to be a 4600, but something went screwy in their system! And I cbf sending it back or buying a new one.

Thanks for the info guys.
