- Schwalbe Marathon Racer 20 x 1.50: Road tires, mainly for asphalt. Very low rolling resistance due to negative profile and good visibility thanks to reflective strips. Idea for the city.
- Schwalbe Durano 20 x 1.10: Road tires, mainly for asphalt. Narrow folding tire with very low weight for maximum speed.
- Schwalbe Little Joe 20 x 1.40: All-round tire, ideal for asphalt and paved paths. Narrow, very light tire with very good rolling properties.
- Schwalbe Little Joe 20 x 2.0: Very wide MTB tire for off-road and unpaved paths. great grip
