Also GoTrax claims it has a 2-year warranty. It might be worth it to see if they’ll send you a new battery for it.
Yeah, maybe someone can explain to me how this isn’t a vehicle at this point. Sure, it’s smaller, but having a 1000 pound vehicle using bike paths and multi-use paths seems dangerous. This feels like someone trying to pass off a small car as a bike in order to circumvent safety standards more than being a real form of micro mobility.
