Replacement inner tubes for HappyRun e-bikes and dirt bikes. Worth keeping a spare with the bike: a tube is the cheapest part on the bike and the one most likely to end a ride.

All of HappyRun's 20 x 4 in fat tire models share one tube, so a single spare covers the G50, G60, G60 Pro, G70, G100 and G100 Pro. The dirt bikes take size-specific tubes, listed separately by model and by front or rear. 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.
