Glad they came in a. 2 pack I accidentally ripped the first try ### ⭐⭐⭐⭐⭐ Correct Sizing *by P***I on 8 August 2024* Two arrived in the box and both are the sizing I requested. I cannot tell the difference between these and others...feel like the same material and I cannot discern if these are any less or better quality. That said, I got my kid's bike repaired and its been 3 months without issues. It's either the tube or the face that my kid hasn't run over something that can puncture it. Time will tell. ## Frequently Bought Together - Helonge 2 Pack 12 inch/12.5 inch Bicycle Tube, 12 1/2x1.75-2 1/4 Tire Tube, 32 mm Schrader Valves, Compatible with 12 1/2 x 1.90,12 x 2.00/ 2.10 Bike Tire, Heavy Duty Cycle Tyre Inner Tube Replacement - 16'' x 1.5/1.75/1.95/2.125 Back Wheel Replacement Inner Tubes (2-Pack) Compatible with Graco Click/Go Jogging/BoB Revolution SE/Pro/Flex/SU - Made from BPA/Latex Free Butyl Rubber - CALPALMY (2 Pack) 12"/14"/16"/18"/20"/22"/24"/26"/28" Kids Bike Inner Tubes Butyl Rubber Fit 1.75-2.125 with Schrader Valve - Compatible with Titan Racing Junior Range Kids Bike, Road/Mountain Bike --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/389567213-2-pack-12-inch-12-5-inch-bicycle-tube-12](https://www.desertcart.tn/products/389567213-2-pack-12-inch-12-5-inch-bicycle-tube-12) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
