Beach Cruiser Bike Inner Tube

Beach bikes run on soft sand, so tires need to be wide and soft with low air pressure to increase surface contact. However, low pressure can bend the tube and cause cracks. This beach cruiser bike inner tube is designed to handle that challenge. Available in 20×4.0 and 26×4.0 sizes, with a wall thickness of 1.2–1.5 mm-much thicker than standard tubes-the joint area is reinforced to prevent cracking under low-pressure riding.

Recommended air pressure is 15–30 PSI, providing sufficient support to prevent sinking in sand. Valves are AV32 mm. Our factory holds 53 patents, including joint reinforcement for wide tubes. Dynamic fatigue tests using our own equipment show a pass rate over 99%. Monthly production capacity is 1 million units, with orders shipping in one month. The MOQ is 10,000 pieces, and sizes can be mixed. OEM is supported. Free samples are available, and custom samples take one week.

Quality follows national standards, with a full check before packing. Third-party inspections are allowed. Warranty is 3 months. Payment terms are 30% in advance and 70% before shipment, accepting USD. We ship DDP to your warehouse. Designed specifically for low-pressure riding, this tube is ideal for beach bike rentals, seaside resorts, and specialty bike shops. Its durability keeps your customers coming back.
