Tire 20" Schwalbe Big Apple 20x2.0 (50-406)

AIR SUSPENSION BUILT-IN. The Big Apple started off the Balloonbike trend more than ten years ago: Comfort without using complicated technology! Air cushion tires are used as natural suspension. Inflated to around 2 Bar a Balloonbike rolls really easily and with a full suspension effect. A normal tire with a width of 37 mm must be inflated to a rockhard 4 bar, in order to roll similarly well.
