A heavy-duty butyl rubber inner tube from Green Line for 14" tires (10" rim) on e-bikes, electric dirt bikes, and small-wheel pit bikes. The 45-degree angled Schrader valve clears hub motors, spokes, and brake discs where a straight stem won't reach, making inflation straightforward in tight wheel assemblies. Thicker-than-stock wall construction resists pinch flats and punctures.
