Trike Sun ev3 with petal Assist no battery!
We found a Trike Sun EV3 with petal Assist. The battery is missing. I have done my research and found that the battery has been discontinued. I was wondering how to go about getting a replacement or upgrade for that battery. I can find other individuals that have converted there other bikes with discontinues batteries to a lithium ion battery but can not figure out what to do for my bike, my husband is a mechanic and I think he can figure it out if I get himt he correct parts and in the right direction. Please help!
