BOSCH DRIVE SYSTEM

GERMAN ENGINEERING

Since the launch of our 2014 range, we have used drive systems from our premium supplier Bosch. Drive units from Bosch eBike Systems give you a unique riding sensation. Three sensors measure the rider's pedal power, cadence and speed over 1,000 times per second. This facilitates an organic interplay between you and your e-bike. The drive unit of the smart system, the new system generation of Bosch eBike Systems, ensures a unique e-bike experience. The smart system combines sophisticated high-quality e-bike components with digital functions, is fully connected and always up-to-date thanks to regular updates over-the-air.

PERFORMANCE LINE CX (BDU384Y...)


The Performance Line CX (BDU384Y) is more responsive than ever to your input. We have reinterpreted and improved the sensor signals. The drive unit does exactly what you want it to do – it is responsive, controlled, and direct. That is a natural riding experience.

Uphill in the flow and downhill in tranquillity: The Performance Line CX (BDU384Y) is quiet. It strikes a balance between power delivery and noise.

The housing can withstand the toughest conditions. It is made of magnesium – robust, corrosionresistant and hard. The sealing concept prevents splash water from entering.

The Performance Line CX (BDU384Y) is about 100 grams lighter than its predecessor.

Power: precise and controlled.

The Performance Line CX (BDU384Y) takes riding dynamics and agility to a whole new level. It is powerful, light and quiet. Ten years of experience and countless trail rides all over the world have gone into its further development.

The Performance Line CX combines power, dynamics, efficiency and altitude. 85-600-340: These values represent the ideal balance between performance and riding fun in relation to wear and range.

PERFORMANCE LINE CX


Powerful: The torque of up to 85 Nm has a noticeable effect on riding behaviour. This accelerates faster, particularly at low cadences, and makes uphill starts much easier. You therefore have more power available in difficult gears.

Impressive performance on the trail: Extended Boost is the unrivalled function for negotiating exposed roots, steps and stones with ease, even uphill. This function enables you to manoeuvre with greater agility and ease on even the most technically demanding trails.

Ready for every challenge: The advanced e-MTB mode ensures even better control on the trail, without having to switch riding modes. The motor responds much more sensitively to the rider's effort, especially in low gears, enabling an extremely sensitive start.

Choosing a sporty riding style can take you further with Tour+ mode. The riding mode rewards your slightly increased power input with greater energy efficiency: The harder you pedal, the more the drive will support you. If, on the other hand, the going is fairly easy, you'll receive less assistance. This means that the battery is discharged more slowly. This will extend your ride, as well as your riding enjoyment.

Finely modulated support: The powerful 32-bit processor enables sensor signals to be processed at high speeds. Performance can be controlled more precisely, offering you optimal support in all riding situations.

The drive unit has highly efficient thermal stability thanks to the modern and innovative electric motor. This ensures high performance even under heavy loads.

Smart and powerful for Uphill Flow

Ride with the ultimate flow with the Performance Line CX motor. Experience intuitive handling and a unique riding sensation with this powerful and dynamic drive unit. With the smart system the drive unit is fully networked with the other components on your e-bike - and with the eBike Flow app you can access digital features such as activity tracking and the e-bike Lock, as well as easily keeping your e-bike constantly up-to-date.

Over-the-air updates

The Performance Line CX is fully networked in the smart system, so it remains up-to-date even after purchase.

Powerful 85 Nm

With a maximum torque of 85 Nm, you really feel the difference in how your eBike handles.

Wireless speed sensor

Keep your eBike looking sleek with a wireless speed sensor, available as part of the smart system.

PERFORMANCE LINE SX


Pedal faster, pick up speed even faster: The Performance Line SX works at least as hard as you do. When riding in a sporty style with a high cadence, it supports you disproportionately to your performance with peaks of up to 600 watts of motor power. With its sensitive and reactive response behaviour, it is ideal for all those who ride in sporty style with electric support and are looking for a training effect.

A significantly reduced pedal resistance of more than 50 percent, the use of narrower cranks and an almost silent motor – the Performance Line SX convinces in many respects. Its direct and sensitive response conveys the natural feel of cycling and enhances it with the ease and fun of e-biking.

Around 2 kilograms: The Performance Line SX is Bosch lightest drive with the highest power density. The Performance Line SX reduces the total weight of your e-bike, delivers greater agility and is ideal for fans of a sporty riding style. In addition, the compact drive unit disappears elegantly into the crank area of your e-bike – so it looks like a conventional bike.

You're looking for a sporting challenge on the trail, on technically demanding passages and when riding uphill? Installed in sporty light E-MTBs, the Performance Line SX is the optimal piece of training equipment for you. You want to ride dynamically on the road with minimalist, agile E-City bikes? Here, too, the Performance Line SX is the right choice.

Sporty lightness

When muscle power and electric support work in conjunction and you get top performance exactly when you need it: With the Performance Line SX, Bosch is launching a sporty drive unit that is lighter and more compact than anything we have developed so far.

PERFORMANCE LINE


Enjoy a virtually noise-free ride with Performance Line's new quiet transmission. Feel at one with nature on long bike rides with a motor that's barely audible.

Get immediate and powerful support in any riding conditions - regardless of how fast or slow you're pedalling. Powering your ride with up to 75 Nm, Performance Line is designed to provide a natural riding sensation. Adjusting intuitively to your riding style, the drive unit makes handling easier and enhances road safety.

Make your e-bike ride even more pleasant with Auto mode. Performance Line automatically switches between Tour and Turbo modes in line with the riding conditions. You don't have to worry about switching modes manually – or working nearly as hard. This leaves you free to focus on the road ahead and to enjoy your ride to the fullest.

You can always rely on the high-quality design of Performance Line. The robust drive unit is built for heavy use - without the need for additional maintenance. It has the durability to withstand extreme weather and challenging ground conditions. This makes it the ideal choice for longer trekking tours.

CARGO LINE


Transport your loads effortlessly to their destination. Whether you're tackling a steep hill or pedalling on the flat, 85 Nm of torque and a perfectly tuned transmission provide powerful yet natural support.

Navigate difficult riding conditions with ease. The multi-sensor concept and sophisticated software enable consistent acceleration and give you a smooth, safe riding sensation. The new Auto mode senses the riding conditions and automatically adjusts the level of support. With no need to switch riding modes, you can concentrate fully on the road ahead.

Specially designed for the Cargo Line, Cargo mode lets you get maximum support from your e-bike, namely 400% of your own pedal power. In addition, Cargo mode optimises start-up behaviour. Despite the high level of support and torque, your e-cargo bike starts smoothly and pleasantly. Prefer different dynamics or torque? Simply use the slide control in the eBike Flow app to adjust Cargo mode to suit.

When you need to get off and push, Cargo Line Walk Assist eases the burden. Press and hold the minus button to activate. As soon as you start to push your e-cargo bike, motor support kicks in. At the same time, the integrated Hill Hold function stops your bike from rolling backwards or downhill. Safety is never an issue, even on the steepest of climbs and setting off on your bike again is effortless.

Save battery power and increase your range: When you cycle faster than 25 km/h, the electric motor and gearbox automatically decouple. This results in minimal pedal resistance and exceptionally smooth handling. Cargo Line is also compatible with shorter pedal cranks. This means better ground clearance and an even safer ride.

Keep your eBike cool, no matter how hard it's working. When pushed to perform, or on hot days, the cooling fins of the Cargo Line keep the heat at bay. With no need to worry about the drive unit overheating, you can push yourself to the limit, even on long summer rides. Cargo Line's compact dimensions and magnesium housing reduce the weight of the drive unit to just 2.9 kilograms. This makes your e-bike even lighter and easier to handle.

The smart alternative to the car

The Cargo Line is now part of Bosch's smart system. Take advantage of continuous component updates over-the-air, or customise your riding modes on the eBike Flow app. Whatever the conditions, Cargo Line is a constant support: Moving heavy loads up steep inclines becomes a breeze.

Robust Cargo mode

Cargo mode is specially designed to support the unique requirements of eCargo bikes. You get maximum performance and 400% support – four times your own pedal power.

85 Nm of torque

There is power of up to 85 Nm behind your eCargo bike, so you can move heavy loads and climb hills effortlessly.

Smart walk assist and Hill Hold

Walk Assist and automatic Hill Hold ensure you're always in control, even when out of the saddle.

ACTIVE LINE PLUS


Together with the Active Line, the Active Line Plus is the quietest drive unit from Bosch eBike Systems – perfect for relaxed rides without annoying background noise.

Natural and dynamic starting is ensured by the Active Line Plus with its sensitive sensor concept, including software. It responds sensitively to your riding behaviour and supports you with up to 50 Newton metres of torque, even if you have to pedal faster or tackle unexpected climbs. This makes it suitable not only for rides in the city, but also for longer tours in urban environments.

Being on the road with the eBike becomes even more pleasant and relaxed thanks to the Auto mode. Headwinds or uphill inclines never catch you off guard again, because the auto mode automatically varies the support depending on the riding situation. You don't have to exert more effort or switch the riding mode yourself. This means you can fully focus on the road ahead and enjoy your ride to the fullest.

If you decide on an e-bike with a hub gear system, you have the option of selecting a backpedal brake with the Active Line Plus. It gives you a safer feeling and increases comfort when braking because you can, for example, give hand signals and brake at the same time.

The Active Line Plus is based on a gearbox that is characterised by particular durability and robustness. This ensures that your riding fun lasts for many years. You don't have to worry about the weather or dirt. Just enjoy your daily rides and leisure tours, because that's exactly what the Active Line Plus was designed for.

Mobility for everyday life

Experience something new: The Active Line Plus is the ideal companion for commuting to work and for excursions within and outside the city. The drive unit ensures smooth, agile acceleration and enables easy handling. The barely perceptible pedal resistance above 25 km/h or in Off mode increases the fun factor when exploring and on every ride.

PERFORMANCE LINE SPEED


Experience the robust support of the high-performance motor - even at high cadences. The finely tuned transmission enables dynamic riding and rapid sprints. You can smash your daily fitness goals on the way to work.

Save battery power and relax while riding in an e-bike group – in Limit mode, the support provided by your S-pedelec ends at 25 km/h instead of 45 km/h. To ensure that you don’t slow down on climbs or in strong headwinds, this riding mode automatically adapts the level of support – without you having to pedal harder or switch riding modes.

Make light work of uphill journeys: Smart walk assist helps you tackle steep climbs. As soon as you start to push your e-bike, motor support kicks in. The handy hill hold function stops your bike from rolling backwards or downhill.
