HappyRun G100 Pro Replacement Battery

A genuine replacement battery pack for the HappyRun G100 Pro electric bike. Capacity drops as a pack ages, so a replacement restores the range the bike had when it was new rather than simply getting it running again. The G100 Pro runs a 72V dual battery setup: an 18Ah pack on top and a 15Ah pack below. They are not interchangeable, and the top pack also comes in yellow or black to match the bike. Packs are not interchangeable between models, and several bikes use different top and bottom packs. Pick the option that matches your exact model before ordering, since parts are not shared across the whole HappyRun range. If you are not sure which version you have, send Adventure Motion support a photo of the original part and we will confirm it.
