2Pcs 14x2.125 Bike Inner Tube with CR202 Valve Stem

Fattbao 14x2.125 inner tubes are a two-piece kit of heavy-duty butyl tubes with CR202 valve stems, reflective stickers and tire levers for reliable inflation and safer night visibility.

These two 14-inch inner tubes are engineered for bikes, e-bikes, scooters and small dirt machines that use 14x1.90–2.25 tires. Built from high-quality butyl rubber and fitted with CR202 valve stems, the set includes accessories—two valve caps, two plastic tire levers and 47 reflective stickers—so you get ready-to-install tubes plus small safety and repair items in one package. This product fits most 14-inch tires by overall dimensions, but it is not compatible with 14" rims specifically labelled otherwise; check tire markings before purchase.

Will these inner tubes fit my 14-inch bike or electric scooter?

These tubes are sized for 14 x 2.125 tires and cover a range of 14-inch widths from 1.90 to 2.25. They work with many children's bikes, compact e-bikes, scooters and small dirt bikes that use the listed tire dimensions. They are not suitable if your wheel or rim requires a different inner diameter or rim-specific tube type.

• Compatible tire widths: 1.90"–2.25" (14x1.90 to 14x2.25)
• Designed for 14x2.125 tire profiles
• Not compatible with 14" rims that require special tube types
• Check tire sidewall for size markings before installing

How durable and airtight are these butyl rubber tubes?

The tubes are molded from high-quality butyl rubber for improved airtightness and longer service life compared with basic rubber blends. Butyl resists gradual air loss and is commonly used where reliability and longer inflation intervals matter. Regular inspection and proper installation will further extend tube longevity.

• Made from high-grade butyl rubber for better seal and wear resistance
• Reduced permeability for slower air loss over days and weeks
• Standard thickness for everyday riding and light off-road use
• Replace if repeatedly patched or if sidewall damage occurs

What does the CR202 valve stem do, and how easy is inflation?

The CR202 valve stem offers a sturdy, easy-to-access inflation point that pairs with most bike pumps and air compressors. Its wider base improves sealing against the rim and reduces the chance of leaks around the valve hole. The kit includes valve caps to help keep dirt out when the wheel is in use.

• CR202 valve stem for convenient pump attachment
• Better sealing at the valve base to minimize leaks
• Includes two valve caps to protect the valve from grime
• Works with common bike pumps and portable inflators

How do the 47 reflective stickers and tire levers help me?

The 47 silver reflective stickers increase visibility when light hits them at night, helping other road users notice you more easily in low-light conditions. They do not glow by themselves but reflect strong light sources like headlights. The two plastic tire levers simplify tube removal and installation for quick roadside repairs.

• 47 silver reflective stickers for increased night reflectivity
• Stickers improve visibility but are not self-luminous
• Two plastic tire levers included for safer tire changes
• Compact accessories fit in a saddlebag or toolbox

Who this kit is for: Cyclists, parents, scooter owners and light off-road riders who need a dependable replacement inner tube with practical accessories. It’s suited to anyone with 14-inch tires in the 1.90–2.25 width range who wants a ready-to-install, long-lasting butyl tube and visibility-enhancing stickers for safer low-light rides. Confirm your tire sidewall reads a compatible 14x dimension before buying.
