im really happy with my GSM mid drive convertion. It's been a revelation and I love using my bike. The only downside is the weight. The bike and kit is really heavy. I want to convert a second bike, is there a lighter alternative?
you should start with a very lightweight bike then we'll look into what kits are available for it.
My bike is 16kgs all in. It's possible to shave about 1kg from it if the battery is a 10S3P instead of a full fat 15AH that's on it.
