I am building a motorized Chinese wheelbarrow.
I'm using a 48" wooden carriage wheel.
View this link for a basic photo idea.

2π x radius = 150.8" circumference of a 48" diameter wheel.
14 tooth freewheel cog on motor
What size tooth gear sprocket for the 48" wheel?
I purchased a 3000w 72v Cyclone motor/system.
Specs on the Cyclone 3000 watt, rpms, etc:

https://www.electricbike.com/taking-...n-ebike-brute/ gives this info:
"The drive gear has 11-teeth, and the output ring gear has 54-teeth.
The 11:54 reduction means the motor spins 4.9 times for every time the output shaft drives the freewheel.
But of course, this is for a 26" wheel. Does the gear sprocket need to be larger or smaller, when a 48" wheel is used?
Thank you,
Darin
