So as a total ebike newb, I have started looking at what I have to change, over and above what was supplied with my conversion kit. One of the first things that is staring me in the face, is the brake levers. My current MTB has Shimano TZ30 combo brake lever and shifter. In order for me to have the cutout switches, I have to install the levers that came with my hub motor. My question is, where can I get plain shifters that will work with my TZ50 7speed derailleur. Does Shimano have an interchangeability guide somewhere on the web or is there some other brand that would work with my cheapy gear set? I thought about removing the brake levers from the existing setup but when I put the new levers on, the old shifters get pushed toward the centre and out of reach of my thumb, without moving my hands off the grip. This might have already been discussed but my search didn't reveal anything specific.
Thanks
