Installing a controller with a higher than 30 Amp output is possible, however, it is not recommended. The MX350 and MX400 motors are designed to run with a 30 Amp controller so installing a controller with an output higher than 30 Amps could possibly overheat the motor under demanding conditions such as climbing steep hills and riding through sand or mud.
Please let us know if you have any questions.
Thank you very much. I placed the order.
Order was shipped and received promptly. Thank you! Installation was simple except the controller mount holes did not line up. Will make an adapter later but for now one screw and a cable tie are sufficing. It is working just as I hoped. Love the variable control and I am thinking this should be less destructive to the free hub. Thanks again for all the help.
You are welcome. We now include a large double sided foam mounting tape square with each kit to make mounting the controller easier.
Great to hear that you got it working with the new parts. Having variable speed control should be much easier on all of the power transmission components including the freewheel. Thanks for letting us know how everything worked out.
