This is basically the exact same motor I have on my Luyuan Condor E-Bike from Mobility Unlimited in Toronto. Putting a 60 volt controller in a 48v system will do absolutly nothing till you increase the battery voltage. Also if your E-Bike has a DC to DC converter you may have to replace that with another unit that can handle the higher voltage.

Thanks,
Ken Finch

My recommendation based on 100's of applications is to do the following on your ride.
1) Add a 72v hi-amp controller
2) Replace 48v DC converter with 75v
3) Add a 16v Li-ion battery pac to raise your voltage to 64v
4) Use your 60v charger

See my other post on what you can expect from this upgrade on a 500w motor
