The new Bosch Performance Line SX Smart System motor

When muscle power and electric assistance work in tandem, delivering peak performance exactly when you need it: with the Performance Line SX, we’re launching a sporty drive unit that’s lighter and more compact than any we’ve developed to date. For light eMTBs, eGravel and eUrban bikes.

Features

Get ahead with a quick start
Whether it’s a Light eMTB or an eGravel bike: a high cadence is rewarded. On rugged terrain or from traffic light to traffic light on your eUrban bike.

A new way of e-cycling
Start pedalling. Feel the assistance: responsive, quiet, direct. A natural riding experience combined with the benefits of an e-bike.

Stylish and unobtrusive
Light, sleek, beautiful e-bikes: the compact Performance Line SX drive unit is concealed within the frames of Light eMTBs, e-gravel or e-urban bikes.

Lightweight and powerful
The Performance Line SX is extremely light and remarkably quiet. When you ride at a sporty pace, it propels you unobtrusively but with noticeable power.

• Up to 600 watts: maximum power in the smallest of spaces
• Approx. 2 kilograms: The lightest drive unit, discreetly integrated
• Max. 60 Newton-metres: Pedal fast, enjoy powerful assistance
• Sprint mode: For sporty e-gravel and e-urban riding

Optimal setup for light and sleek e-bikes

For sporty riding
Pedal faster, pick up speed even quicker: the Performance Line SX works at least as hard as you do. When riding in a sporty style with a high cadence, it provides you with assistance that far exceeds your own effort – with peaks of up to 600 watts of motor power. With its characteristics and sensitive, responsive behaviour, it is ideal for anyone who wants to ride sportily with electric assistance and reap the training benefits.

Lightness – almost natural
A reduction in pedalling resistance of more than 50 per cent compared to the Performance Line CX, a slimmer crank design and an almost silent motor – the Performance Line SX impresses in many ways. Its direct yet responsive handling conveys the feel of conventional cycling whilst adding the ease and enjoyment of e-biking.

Light, compact, agile
Around 2 kilograms: the Performance Line SX is our lightest drive system with the highest power density. Take dynamic corners on your eGravel bike and carry your eUrban bike right up to the fourth floor: The Performance Line SX reduces the overall weight of your e-bike, offers greater agility and is ideal for fans of a sporty riding style. What’s more, the compact drive unit blends discreetly into your e-bike – giving it the look of a conventional bicycle.

Versatile: sporty riding
Are you looking for a sporting challenge on the trail, on technically demanding sections and when riding uphill? The Performance Line SX, fitted to sporty Light eMTBs, is the perfect training machine for you. But even if you’re dreaming of long-distance adventures and don’t yet know exactly what terrain lies ahead, the drive unit is ideally suited as a powertrain for eGravel bikes. Do you want to ride dynamically on the road with minimalist, agile eCity bikes? Here too, the Performance Line SX is the right choice.

Sprint mode
Dynamic assistance that increases with cadence – for fast sprints and steep climbs.

• Dynamic assistance of up to 280 per cent of your own power – the faster you pedal, the more assistance the drive provides
• For sprints, steep climbs or fast commuting
• ideal for eGravel and eUrban bikes
• Customisable via the eBike Flow app

eBike Flow app

The eBike Flow app is the centrepiece of our smart system and enables you to enjoy a better, connected riding experience: safer, more personalised and more comfortable.

eBike Lock – Free additional protection against theft

The perfect complement – park your eBike. Enjoy some downtime.
eBike Lock is free for all eBikes with the smart system. When you switch on your eBike, it automatically checks whether your smartphone is nearby to act as a digital key. Only then is motor assistance activated and your eBike unlocked.

Display as a key – use your Kiox 300 or Kiox 500 as a key
It’s as intuitive as it sounds: simply remove the display from its mount and stow it away. This gives your eBike an extra layer of protection in no time. Reattach the display to activate the motor assistance and set off.

Unlock via smartphone – manually unlock your e-bike using your smartphone
Instead of automatic unlocking, you can also unlock your e-bike manually via your smartphone using a button on the home screen.

Battery Lock – Digitally lock the battery

Additional protection – protect a valuable component of your e-bike
With Battery Lock, you can provide additional digital protection for your e-bike battery: this feature ensures that your battery can no longer be used if it is stolen.

Digital keys – Flexibility with a digital key
You can use several digital keys at the same time for Battery Lock: your smartphone with the eBike Flow app, as well as your Kiox 300 or Kiox 500.

Flow+ – Premium service with Flow+
Battery Lock is available as a premium service from Flow+. You can try Flow+ for free – for 12 months with the ConnectModule. Without the ConnectModule, you get one month free.

Protect your eBike – eBike Alarm

Park with peace of mind – valuable location and status information
Whether you’re just parking your eBike for a short while or will be away for longer, you stay connected and relaxed via your smartphone.

Two-stage alarm – Audible and visual alarm
Your eBike will alert you with audible signals and flashing LEDs if it detects movement or is being moved. You’ll also receive a notification on your smartphone.

Tracking functions – Helpful location tracking
If your e-bike is moved significantly, you can track its location using the tracking function.

eBike Pass – All your data always to hand
With the eBike Pass, you can keep track of important information about your eBike. Data relating to your eBike is stored here. You can add details manually – even independently of eBike Alarm.

Theft Report – Quick Assistance in the Event of Theft
If your eBike is stolen, you can create a document containing all the key information about the incident for the police, based on the data from the eBike Pass – and add a live tracking link.

Navigation – Exploring means experiencing

Route planning – Plan according to your needs
Choose the route profile and map details that suit your ride. Plan your own routes with waypoints or import existing ones from komoot.

On-screen navigation – Navigate precisely using your display
The navigation function for the Kiox 300, Kiox 400C and Kiox 500 guides you precisely to your destination – with turn-by-turn directions and clear route guidance. If you’ve subscribed to Flow+, you’ll get even more map detail on your display.

Ride Screen – Turn your smartphone into an e-bike display
With the SmartphoneGrip, you can use the Ride Screen. It not only shows you all the important ride data, but also offers full navigation with 3D map views – even in portrait mode.

Activity Tracking – Automatically record and analyse your ride data
The eBike Flow app records your ride data as soon as you set off. In the statistics, you’ll find valuable insights into your ride and fitness data – to analyse and share. If you wish, all data is also automatically synchronised with Apple Health.

koomot and Strava – Connect the eBike Flow app to your favourite apps
Transfer your routes from komoot to the eBike Flow app, synchronise your activities with Strava and share your achievements with your friends or your community.

Personalise your eBike – as unique as you are

Display configuration
Configure your Kiox 300, Kiox 400C or Kiox 500 display to suit your needs. Create new screens with your preferred information. Choose from over 30 display options and arrange them as you wish.

Custom riding modes – fine-tune and adapt
Assist, Dynamic, maximum torque and maximum speed – you decide what you need. You can also put together your favourite riding modes. Choose from all the riding modes available for your e-bike.

Performance Upgrade 2.0 – Performance redefined
Unleash more power for your e-bike. The Performance Upgrade 2.0 delivers not only better acceleration but also stronger assistance. Thanks to software optimisations, you’ll enjoy more powerful propulsion and maintain speed for longer – whilst retaining even more precise control. Maximum torque of up to 120 Nm via update. Variations may apply depending on the type of gear system. Higher performance settings may lead to increased wear and reduced range. The e-bike manufacturer may limit the maximum torque at the factory. In the eBike Flow app, therefore, only the maximum value authorised by the manufacturer can be set.

CO₂ savings

Trick Check – More skills. More fun.
Improve your skills and analyse your performance: Trick Check automatically recognises and records the type of trick you’ve performed, whether it’s jumps, stoppies, manuals or wheelies. To help you improve your riding technique, you’ll receive immediate feedback on the display and via an audible signal. Whilst riding, you’ll see the distance, duration, height or angle on your display for eight seconds. After your ride, you’ll find your best results in the eBike Flow app. This feature is enabled by default on your Kiox 400C and Purion 400. For all other displays, you can activate this feature at any time in the display settings, as well as switch the audible alert on and off. The sensors are calibrated to respond only to distinct tricks.

Trick Check works with the Performance Line CX (BDU384Y), Performance Line CX-R (BDU384Y), Performance Line CX Race (BDU374Y), Performance Line CX (BDU374Y) and Performance Line SX (BDU314Y), and on the following displays: Kiox 300, Kiox 400C, Kiox 500, Purion 200, Purion 400.

Bosch System Controller

Minimalist, robust control unit
The System Controller is a control unit for eBikes with the smart system, stripped back to the essentials.

Connected via the smart system
The System Controller makes your e-bike smart and acts as the interface for software updates.

Fitted in the top tube
The System Controller is barely noticeable; it is made from robust material and is therefore protected against knocks and scratches.
