## Long description

The Bicycle Inner Tube Presta Valve Fisher-Price 85121 is a replacement inner tube designed for 12" bicycle wheels. It features a Presta valve compatible with presta-equipped rims and a durable black rubber construction intended to provide reliable air retention and basic puncture resistance for children's bikes and small wheeled cycles. Each pack contains one inner tube sized to fit 12" wheels and intended as a direct replacement to restore rideability after a puncture or during routine maintenance.
Advantages
This inner tube offers a standard Presta valve that is commonly used on narrow rims, allowing straightforward inflation with compatible pumps or adapters. The black rubber material balances flexibility and strength for typical low to moderate pressure applications on 12" wheels. Supplied as a single unit, it provides a simple one-for-one replacement that reduces downtime and is suitable for quick roadside or workshop repairs.
Suitable for
12" children's bicycles and balance bikes with Presta valve rims
Replacement inner tube for scooters or small trailers that use 12" bicycle tubes
Maintenance kits for schools, daycares, or bike rental services with small wheel fleets
Key specifications
Wheel diameter: 12 inches
Valve type: Presta (narrow threaded valve)
Material: black rubber inner tube
Pack quantity: 1 inner tube
Designed pressure range: suitable for low to moderate tyre pressures typical of 12" wheels
How to use
Remove the wheel from the bicycle and deflate the tyre completely before separating the tyre bead from the rim. Inspect the tyre and rim for sharp objects or damage, then insert the inner tube through the tyre opening, aligning the Presta valve with the rim valve hole. Seat the tyre bead back onto the rim evenly, ensuring the inner tube is not pinched between the tyre and rim. Partially inflate the inner tube to check seating, then fully inflate to the recommended pressure for the tyre. Reinstall the wheel on the bicycle and perform a final pressure check and visual inspection before riding.
Usage recommendations
Use a compatible pump or an adapter for Presta valves. Regularly inspect tyres for embedded debris and avoid overinflation beyond the tyre manufacturer’s recommended pressure. Keep a spare inner tube and basic repair tools on hand for faster roadside repairs.
