Hi everyone,
I’ve always wanted a Cowboy e-bike, and I might finally have the chance to get one. It’s a Cowboy C3 with only about 500 km (310 miles) on it, and the seller is asking €400.
The catch is that the battery doesn’t work anymore because the bike has been sitting unused for a long time. According to the seller, everything else is in great condition.
I’m wondering if this is still a good deal. Has anyone here had experience reviving or repairing a Cowboy battery after long-term storage? Is it usually repairable, or would I most likely need to buy a new battery?
Would you take the risk at this price, or should I pass?
