| Air suspension built-in. The Big Apple started off the Balloonbike trend ten years ago: Comfortable cycling 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 rock-hard 4 bar, in order to roll similarly well.  | BIG APPLE PLUS. Now enjoy Balloonbike comfort with extra safe 3 mm GreenGuard puncture protection. | |
