WOOM bikes originally have Schwalbe inner tubes, but WOOM 4 ORIGINAL and OFF (AIR) 4 gen A also fit a. MAXXIS 20X1.5/2.5 AV 48mm Weight 125g or 20g lighter. 0.8mm thick. b. TUBOLITO TUBO-BMX 20x1.5/2.5 AV 40mm 67g, which is almost half the weight and 2x more durable in tests. Thermoplastic.

Schwalbe's main advantage over them is the silver threaded aluminum valve, i.e. the overall picture + the possibility of locking the valve with a bolt.
