Cargo Line is the motor Bosch built for cargo bikes, so it’s tuned for starting off and climbing with a load, whether that’s kids, groceries or deliveries. It responds the same way loaded or empty, so the bike feels predictable. For the 2021 model year a software update raised the System 2 Cargo Line to 85 Nm of torque and gave it stronger support at low cadence, so you get going from a stop more easily.

Today’s Cargo Line runs on the Bosch Smart System (2022 and later). The 4th-generation Smart System Cargo Line stays at 85 Nm. The 5th-generation Cargo Line (drive unit BDU384Y, 2025) can get Bosch’s free Performance Upgrade through the eBike Flow app, which raises it to 100 Nm and 750 W, once your bike’s manufacturer releases it for that model.
