When I received the 63/74 I was rather deflated by the small size and weight. Can this thing really hold a candle to the big old Unite motor?

Thanks for the heads up! There is a high speed option 70,000 ERPM for an extra $50.Thud wrote:Kelly's 40k is E-rpm....you will need to divide that by the pole pairs in your motor (7) for a maximum rpm of 5715 (30% short of your motors potential)

So this motor will go to 8krpm? Wow, I'll definitely have to play with my gearing...

I didn't find a spec on ERPM for the Lyen either... Keep in mind that I ultimately see myself with an 80/100 (or bigger) in the future, so I want a controller with plenty of 'balls' in reserve...
Are the Lyen controllers hard to program? The Kelly's a have a nice and simple menu system.
@gogo The scooter runs 10in tyres, so I should be able to get desirable gearing with a single stage reduction...
The answer is always 'more power, fcuk the question!'gwhy! wrote:How much power do you want in your scooter?
