The Big Apple started off the Balloonbike trend more than 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.Specifications:- Execution: K-Guard- Compound: SBC- Weight: 340 g- Skin: Lite- Bar: 2.0-4.0- Psi: 30-55- EPI: 50- Load: 60 kgTechnology:Dynamo:- With dynamo ribbing.E-Bike ready 25:- In standard pedelecs that have motor assist up to 25 km/h, there is no legal requirement for a special tire. But even with these bikes, loads and average speeds are higher than in regular bikes, therefore we recommend only certain tires as ?E-Bike Ready 25?.Balloonbikes:- Air suspension built-in.Performance Line:- Excellent quality for intensive use.- These are the best value for money tires.Active Line:- The basis for all Active Line tires is the high-quality 50 EPI carcass. SCHWALBE no longer produces tires with a coarse 20 or 24 EPI carcass. In addition, K-Guard provides effective puncture protection for Active Line tires.
