With the Big Apple, the trend for Balloonbikes began over ten years ago: comfortable cycling without complicated technology. The air cushion of the tires is used as natural suspension. At around 2 Bar, a Balloon tire rolls wonderfully lightly and with full suspension effect. A normal tire with a width of 37 mm must be inflated to a hard 4 Bar to roll similarly well. An additional rubber coating on the side protects against cuts and allows for even coloring. It leaves no dark marks on gym floors. It lasts significantly longer than a gray wheelchair compound. The protective insert is reinforced with Kevlar fibers. This is the protection standard for all tires in the Active Line. E-bike compatibility: without manufacturer recommendation. Delivery includes: single unit. Maximum load capacity: 55 kg. Puncture protection. Dense carcass fabric: 50 TPI. Pressure: 2 Bar - 4 Bar. Pressure: 30 - 55 psi. Tread: HS430.
