Want to buy an x-class but am worried about support for it in 3-5 years. If the battery connector to the controller is a standard one then I could find the battery on Amazon or eBay if anything ever happened to Ariel Rider. But if it is proprietary like RAD Power Bikes then it would be very difficult to find a replacement battery in the future. So many e-bike companies stop selling products and accessories for their bikes. Anyone with an x-class know if the battery connector to the controller is standard such as this one?
