The bmsbattery website has the measurements of the hub , this can be compared with the trike , There are 3 different speeds available . 201 is the one used most by 26" plus wheel sizes and 328rpm on the smaller wheels , this is because the 328 has less torque.
The C version denotes the cassette hub version . We use the Q100 328 in our 20" builds , there is also a mid rated motor available on their website.
Next stage is strip the old kit off , so far it looks miserable outside.and today's enthusiasm has not been delivered .
Short term l will use the 2nd battery off my 20/20 until my funds build back up and I order a 36v 15ah bottle battery , that will give over 35miles range.
The X type has spent my "this months money " on a pas/water pump assembly.
Updates later with new photos as something happens, just heard a rattle at the door , could that be the enthusiasm being delivered.?
