hi everyone, i'm new on the forum. i have a currie e-ride. it's quite old i believe, not sure because i'm borrowing it from my brother for a while, to get to and from work mostly. well i work at 4 tomorrow, and suddenly the battery won't lock to the frame. it almost feels like i'm trying to twist a stripped screw when i try to lock it in. i was hoping someone might have an effective short term fix for this, as i need the bike to get to work. also, how difficult is it to replace just that little lock? the part on the frame looks fine to me, though i don't much know what to look for. any help you could offer would be super appreciated. thanks!
