I have a 2012 GEM E6 that is not currently working. It worked the first year I owned it but then started having problems with keeping acceleration so I have replaced the motor controller, pedal and installed new Lithium Ion batteries. I took it into the shop and they couldn’t figure out the problem either. Everything fires up but will not go into gear or move forward or backwards.
I don’t have the knowledge or time to keep moving with the project. I have over $10k invested and would like to get $5k. I will upload pictures when I get it back from the shop. Please reach out if you have any questions.
