Wife has m/s and uses a Segway. She needs to change due to balance and agility issues as she approached 65. She needs: Range, a couple of miles - slowly. Bought her a Terratrike Rover. She can't get it going from a start, she can't do the hill home after walking the dog. I'm a wrench and can fix anything. Can one of you hold my hand and cut thru all research. Hub or mid drive? Who's got the kit? Something that makes me think instead of throwing cashish at it preferred. I know, it's all here in the forum, I know.
