So I was looking into getting either the happy run g60 or the ridstar q20 48v 20 ah.. Now I’ve been looking endlessly on how I can mod either or to get Atleast 35+ mph out of them whether I buy a 60v 30ah battery not sure but, I need some recommendations I’m new to this scene and I don’t know where to start, what to buy in addition to whats given stock. I would build my own bike but I don’t have any equipment and working with some what of a budget
