Bosch Performance Line CX Gen4 Motor Overview
The Bosch Performance Line CX Gen4 Motor is a genuine BDU450CX drive unit for Bosch eBike System 2 bikes. These motors are unused OEM stock with 0km use. However, they are Grade C units with external damage and are sold strictly for spares or repair. They are not compatible with the Bosch Smart System, and no returns are accepted.
The damage varies between individual units. Therefore, the motors shown in the images are examples only. Some units may be in better cosmetic condition, while others may have heavier marks, scratches, chips or damaged mounting points.
Although the internal motor is unused, the outer casing may require replacement before installation. In many cases, buyers may need to fit a new housing or transfer the casing from their existing compatible motor.
Software is already installed. As a result, the motor may work as a plug-and-play replacement when the existing bike settings match. However, it may need programming to the exact bike specification through Bosch diagnostic software.
We can put buyers in contact with a registered Bosch service centre after purchase. The service centre can assist with programming, inspection or repair. Please confirm that your bike uses a BDU450CX motor before ordering.

Bosch Performance Line CX Gen4 Motor Performance & Use
The Bosch Performance Line CX Gen4 Motor provides strong support for compatible electric mountain bikes. Because it delivers up to 85Nm of torque, it offers powerful assistance on climbs and demanding terrain.
In addition, the compact Gen4 design keeps the motor weight to approximately 2.9kg. As a result, it provides strong support without adding unnecessary bulk to the bike.
However, these Grade C units must be inspected before use. External damage may affect the casing or mounting points. Therefore, casing replacement or professional repair may be required before installation.
The installed software may already match some compatible bikes. In that case, plug-and-play operation may be possible. However, Bosch drive units are normally configured to the specific bike through Bosch service software.
For this reason, professional inspection and installation are strongly recommended. A registered Bosch service centre can check the housing, mounting points, software and bike pairing before the motor is used.
