E-bike power race wanes as quiet motors become a survival requirement

Riders who have spent time on electric bicycles quickly learn that high output alone does not define the experience, with silence playing a key role. Bafang, one of the world’s largest e-bike motor makers, has long focused on reducing noise. It separates electromagnetic and mechanical sources, using simulations, materials, structural rigidity, gear design, balancing and low-noise bearings. Bafang also runs an acoustic lab and remote testing to analyse frequency effects under varied conditions.
