Bosch Performance Line CX Generation 5 – Smart System

The Performance Line CX (BDU384Y) takes riding dynamics and agility to a whole new level. It is powerful, lightweight and quiet. Bosch’s focus: the ultimate uphill flow.

The Performance Line CX (BDU384Y) offers you, as standard, the perfect balance of performance and riding enjoyment in relation to wear and range, with performance figures of 85 Nm, 600 watts and 340% assistance – for a natural riding experience. New – Available from mid-July 2025: Choose for yourself and boost your drive unit’s performance figures: more power, higher torque, increased support factor.

• 100 Nm max. torque
• 750 W max. motor power
• 400% max. assistance factor
• 2.8 kg motor weight (100 g lighter than its predecessor)

The Performance Line CX responds more sensitively than ever before to your input.

Bosch has reinterpreted and improved the signals from the sensors.

The cadence sensor measures how fast the cranks are turning.

The torque sensor measures how much force is being applied to the pedals.

Acceleration and position sensors detect how the e-bike is moving.

The Drive Unit does exactly what you want it to – responsively, precisely and directly.

All the possibilities. Your choice
The higher torque ensures stronger acceleration. The increased maximum power makes record times possible. The enhanced assistance quadruples your own effort.

eMTB+ mode
With the built-in ‘Dynamic Control’, you ride with full control, even when you’ve increased your performance settings. On steep, bumpy terrain, you’ll enjoy confident propulsion, whilst on loose or wet surfaces it acts like traction control.

eMTB mode and Extended Boost
eMTB mode responds progressively to your input and instantly detects, based on your pedal pressure, how much power you want – dynamically, with maximum traction and always in a controlled manner. With the integrated Extended Boost, a targeted push on the pedal is all it takes for the drive unit to propel you effortlessly over steps and stones.

Push Assist and Hill Start Assist
With the push assist, you can push your eMTB easily, whilst the drive unit automatically adjusts the pushing speed to the gradient and terrain. In addition, the hill start assist enables a controlled start with strong traction, even on steep terrain. In both cases, Hill Hold is active: your eMTB stays in place and doesn’t roll back unexpectedly.

Bosch eBike ABS Pro
ABS Pro is ideal for professional eBikers: designed for fast, sporty downhill riding and braking. You can make full use of your braking skills whilst still feeling how the system enhances performance.

eShift with TRP
You can choose whether eShift with TRP should change gears automatically for you, or whether you’d prefer to change gears yourself with quick manoeuvres on varied terrain – simply at the touch of a button. With eShift, gear changes are efficient and precise.

PowerMore 250
Compact and weighing just 1.5 kilograms, the range extender can be easily attached to the water bottle cage. It is compatible with all batteries in the smart system. Please check in advance whether you can use the range extender with your e-bike.

Customisable riding modes
Your trail, your riding experience, your mode: using four parameters, you can easily tailor the riding modes to your needs via a slider in the eBike Flow app. Assistance, dynamics, maximum torque and maximum speed – you decide what you need.

Powder-coated. Robust right down to the tips

• The housing is made of magnesium – robust, corrosion-resistant and hard.
• The sealing design prevents water spray from entering.
• Bosch has managed to reduce the noise generated by the gearbox.
• The Performance Line CX motor is quiet. It strikes a balance between power delivery and noise levels
