Mavic E-Speedcity 650B Rear Wheel The new Mavic E-Speedcity rear wheel is made to last and endure, on an e-bike or a muscular bike, because Mavic know there is nothing worse than being stopped by a mechanical issue on your way to or from your destination. Their maximum load capacity is 25% higher than the usual Mavic road wheels to take into consideration the extra weight and loads involved by daily commutes. Offered in 2 different diameters (700 and 650B), they will fit most bikes. Key Technologies The aluminum used to manufacture those rims is made of 90% of recycled aluminum The wheels are entirely made in Europe with 100% of their components either produced directly by Mavic in France or sourced from European suppliers The 650B version features 30mm wide rims which are adapted by the new "SUV" style of e-bikes Pinch Flat Protection (PFP) sidewall: Is an ebike specific innovation to significantly reduce the risk of tyre cuts and punctures The very high-quality hubs used are directly derived from our high-end wheels. Rolling on super smooth bearings to reduce the rider's effort Built with sturdy j-bend spokes, they are easy to maintain Whilst looking discreet to avoid thieves' interest, they do glow at night to keep you visible and safe, thanks to their unique black reflective decals For longevity of the wheel, Mavic recommends that the total weight supported by the wheels doesn't exceed 180kg, Ebike included
