Replace your Schwinn trike's old pneumatic tubes with this great 26"x2" bicycle inner Tube for the Meridian 26" 3-wheeler. This compatible replacement tube sports a straight Schrader valve, and it's from Sunlite Cycling, a respected name in aftermarket bike parts and accessories.
Inner tubes are the most commonly replaced bike (and adult trike) parts, and these tubes will get you rolling right along.
Note: When inflating a bike tube, please use your best judgment. The recommended PSI for an inner tube can vary depending on elevation and air pressure, and should not be taken as absolute.
