Compatibility

Compatible with all Bosch Smart System (BES3) motors: BDU3142, 3143, 3144, 3145, 3320, 3340, 3360, 3741, 3741 CX, 3761 CX Race, 3840 CX. Your handlebar must be 31.8 mm at the clamp area Ñ measure before ordering, or see the 35.0 mm retrofit kit if yours is larger.

31.8 mm Or 35.0 mm?

Most road and trekking e-bikes use 31.8 mm handlebars; many modern eMTBs use 35.0 mm for added stiffness. The mounting diameter must match your bar exactly Ñ the clamp will not flex to accommodate a different size. If unsure, measure your handlebar with callipers or send upVolt a photo.

Professional Install Recommended

Bosch recommends retrofitting be done by an authorised dealer Ñ the Smart System requires diagnostic pairing to register the new display. upVolt can install for customers near our workshop, or we'll recommend a partner dealer near you. Genuine Bosch OE with full warranty.
