Schwalbe Air Plus:
IDEAL FOR E-BIKES AND CARGO-BIKES: Schwalbe Air Plus bike tubes are made for all cyclists that want to pump less and ride more. Thanks to its characteristics, this tube is especially well-suited for bike types and uses where a high burden is expected – such as with e-bikes or cargo-bikes.
HIGHER AIR RETENTION: Thanks to the higher level of pure rubber, Schwalbe’s Air Plus tubes holds air significantly longer than normal bicycle tubes. So you don’t have to re-pump as often.
MORE PUNCTURE PROTECTION Thanks to its ~70% stronger wall thickness, the Schwalbe Air Plus tube is especially robust – so it has extra protection against punctures and damage.
