Overview
OneUp's E-Chainguide is a 45 g, motor-mounted chain guide for Bosch e-bikes that fits 32–38T rings. It is listed on the US store only; no EU price.
The E-Chainguide is OneUp's chain guide for e-bikes with Bosch motors. It bolts directly to the motor, installs without removing the cranks, and needs a single 4 mm hex key for fitting and adjustment. The upper guide flips open without tools for chain cleaning.
It fits 32T to 38T chainrings, offers up to 6 mm chainline adjustment with spacers and weighs a claimed 45 g. The back plate is 7075 aluminium. A black top guide is included and six other colours are sold separately. OneUp lists several frames and the 2025 Performance Line CX (BDU384Y) as incompatible.
