Hi, everybody. I'm hoping to be able to build my own E-bike this year. Currently I have a 21 speed GT mountain bike that I'd like to convert using a rear hub motor kit. My concerns are that most of the kits include brake levers that cut off the electric power and they have a twist throttle on the right hand grip - well my GT has Shimano "trigger" shifters with the brake levers integrated with the body of the shifter so I'm trying to figure out if it's even possible to make this work with one of these kits. I'm hoping that someone else may have been in a similar situation and wondering how they got around it. Thanks in advance!
