The Bafang BBS is a universal electric crankset motor renowned for its reliability, power and ease of installation. Designed to convert almost any bike into an electrically-assisted bicycle, it integrates into the crankset, replacing the standard bottom bracket.
Available in several versions (BBS01, BBS02 and BBSHD), it offers smooth, natural assistance, perfectly suited to road, mountain bike, trekking or urban commuting.
