Electric Bike / Scooter Tire & Tube Set -- Size 14 X 2.125

5 out of 5 stars

Electric Bike / Scooter Tire & Tube Set — Size 14 X 2.125
Got this Tire and Tube set for my Electric Bike Scooter that has 14 X 2.125 tires. The tire is of a good tread thickness and compatible to the tire that was originally on my bike. The tube has the angled valve stem which makes it much easier to fill on tires that have a center motor. Definitely will order this set again when in need of tire and tube replacement.

    I purchased these inner tubes for my 14" Engwe T14 electric bike, which I keep in Europe. I won’t be able to actually install or test them until March, but my first impression is quite positive. The material feels strong and well-made—thick enough to inspire confidence without being overly stiff.

    My bike originally came with tubeless tires, but after experiencing a sudden loss of air in the front tire during a ride (with no visible puncture), I decided it would be safer to add tubes for extra reliability. These seem like the right choice for that purpose.

    The price is reasonable for the quality, and everything arrived in good condition. I’m giving four stars for now, mainly because I haven’t tested them on the road yet, but based on build quality alone, they look like a solid and dependable option.

Product Summary: 14×2.125 Bike Inner Tube,14 Inch E-Bike Tubes with Angled Valve Stem for Electric Bicycle, E-Bike and Electric Scooters

From Molibisty
Included：2pcs 14 inch bike tube with 90° CR202 Angled Valve Stem，which is used to replace 14×2.125 / 57-254 Electric bike Tire tube.Pls check the information of our bike tube to make sure it’s correct model.
Butyl Rubber: 14 x 2.125 inner tube is made of butyl rubber, which has airtightness, elastic damping, anti-aging performance, and high heat resistance.Furthermore, compared to ordinary rubber, butyl rubber has a longer service life.
20% Thicker：Compared to ordinary inner tubes, MOLIBISTY inner tubes are 20% thicker, which better absorbs shocks caused by bumps, providing a comfortable riding experience and excellent handling performance.
Excellent Shock Absorption and Airtightness:The 14×2.125 inner tube ensures airtightness and shock absorption, with 8 times better air retention than natural rubber. The sealing system consists of a 90° valve stem and a valve core cap. The black sliding valve core cap creates a unique sealing environment, preventing air leaks from the inner tube.
Tips:Before installation, please clean the inside of the outer tire to remove any sand, pebbles, or sharp debris that could puncture the inner tube. Check the valve position to ensure correct alignment during installation.
