I was just wondering if anybody has any experience with upgrading the controller for the radrunner Max. I live in a pretty hilly area and I use this bike to take my little guy to school in the warmer months and so I just was looking for a little extra power and help on the big Hills. I did purchase one from a company that said it would work but then when we got it the plugs didn't match up. When we reached out to said company, they responded saying that we had to cut the connectors off and splice the wires together which we didn't want to do. So wondering if anybody has any leads or experience with this. Thanks
