Keep your 20 inch e-bike rolling

This 20 inch e-bike fat tire inner tube gives you a ready spare for the rides that end with a soft wheel and a slow walk home. It's made to fit fat tires on models like QS7, S20, H20Pro, G23, A5, S21,, and S8, so you can swap in a new tube without guessing.

Built for wider rubber

The thicker rubber has that slightly matte feel you want when you're handling a fat tire inner tube replacement. It seats cleanly inside the tire and holds its shape while you work. A practical pick for 20 inch e-bike accessories.

Worth packing with tools

Keep one with your pump, levers, and patch kit. It's one of those e-bike fat tire essentials you don't think about until a curb pinch or thorn makes itself known. Then it matters.
