Looking @ Purchasing a Relay and have kind of accepted the fact the Fazua motor may have issues. My next concern is battery charging. Looking @ my current bike the down tube always has either a layer of dirt so every battery removal will require some amount of cleaning. Now my real concern is wear and tear on the battery mount & connection - am I overthinking this? I read somewhere it is a flimsy setup. My buddies emtb has a rubber plugged charge port that is easy peasy.
