Feature:
【GOOD CHOICE】: Can be used normally for more than 100 days after inflating, and it is the most commonly used inner tube material. More importantly, equipped with a bent valve, it will never let your electric bicycle go flat with a replacement inner tube tire on hand.
【GREAT WORKMANSHIP】: The rubber inner tube has excellent air tightness, good resistance to cold and heat and aging resistance.
【SAFE FOR RIDING】: The rubber tire inner tube can absorb the vibration of uneven roads, quite comfortable and safe for driving.
【SAVING TIME】: The Bike Inner Tubes is simple for installation, which can be easily replaced within a few minutes, more time‑saving and efficient.

How to Use:
1. Carefully remove the tires.
2. Remove the tire from the rim.
3. Remove the old inner tube, check the tire damage, find out and eliminate any objects that may cause air leakage.
4. Insert the inner tube valve into the small hole of the steel ring, and put it into the outer tube completely.
5. Assemble the tire on the steel rim.
Note: Avoid clamping the inner tube between the steel rim and the tire lip or tool.
6. After ensuring that the inner and outer tires and steel rims are installed correctly, use manual or foot‑operated inflator to inflate slowly. If there is any abnormality, please deflate and reassemble before inflating.
