Yes, we can. However… we will not!
Please do not ask us to overvolt or otherwise modify your eBike to exceed 20 mph. First off, we have yet to have a customer who has (on their own) overvolted their electric bike to go above 25 mph and avoided a hospital visit within their first 6 months of doing so.
That’s right, every customer we know who has broken the speed requirement for their eBike has injured themselves. Secondly, if we did the modification and someone injured themselves, they might sue us, and it simply isn’t worth losing our eBike shop for a few dollars.
