The safest Energizer. Outstanding GreenGuard 3mm punctureprotection. Specially made for E-Bikes. The high-quality compound has a low rolling friction and above all very good grip. That means security - also in fast cornering. All Energizers have the ECE-R75 mark and are thus certified for use on faster E-Bikes up to 50 km/h. This ECE regulation is valid European-wide. Certificates of conformity from the tire manufacturer or indemnities are therefore no longer necessary.
