The Active Line Plus is 25% smaller than previous Bosch drive systems and hence integrates optimally into the bicycle frame. The reduced weight and low centre of gravity enable safe handling. It is extremely quiet and offers only minimal running resistance, which is crucial, especially at speeds above 25 km/h. With more than 1,000 measurements per second, the intelligent 3-sensor concept ensures extremely harmonious performance.


Quiet and longer-lasting - Specially adapted to the performance requirements of an e-bike, Gates engineers have developed a new, remarkably durable and maintenance-free system. It's 20% lighter and lasts up to 10 times longer than a well-maintained steel chain.


The SD3's Bosch PowerTube is a modern lithium-ion battery with an integrated battery management system and 500 Wh energy capacity. As an Intube battery, it disappears discreetly in the frame of the SD3. It can be easily installed and removed and, optionally, also charged directly on the bike.

erhältlich mit zwei Lichtanlagen

Im äußerst kompakten Design der Supernova MINI 2 kommt die einzigartige Terralux 3 Linse zum Einsatz. Die Helligkeit beträgt nun 235 Lumen.

Der eingebaute Überspannungsschutz in Kombination mit einem Softstart beim Einschalten sorgt für eine lange Lebensdauer der MINI 2. Durch eine ausgeklügelte Lichtlenkung bringt die Terraflux Linse 90 % des Lichts dahin, wo es am dringendsten gebraucht wird: auf die Straße.

The M99 MINI Pro 25 is the first approved headlight with high beam and low beam to comply with the new European Road Traffic Licensing Regulations. A high beam is essential, especially in off-road use, because it significantly improves the illumination of the trail. As it illuminates the entire environment, safety is massively increased. So after a sporty night ride, the integrated low beam can ease your drive home – without dazzling oncoming traffic.

Erhältlich mit folgenden Kommandozentralen

We install the Bosch Purion compact display as standard on the SD3. It combines remote control and display element in one housing. The position on the left handlebar grip is less susceptible to damage in the event of a fall, and it also leaves space in the centre of the handlebar for attaching a smartphone. Two large, multi-functional plus and minus buttons call up essential trip data such as total mileage, range and distance. The standard display provides information on the current speed, battery level and support level.

Einfache, intuitive und sichere Bedienung an der separaten Bedieneinheit zeichnen das Intuvia aus, welches für das SD3 optional erhältlich ist.

Nicht nur das Schalten zwischen den fünf Fahrmodi plus Schiebehilfe, auch das Abrufen von Informationen wie Geschwindigkeit, Ladezustand, Distanz und vielem mehr könnte nicht einfacher sein. Darüber hinaus zeigt die Schaltempfehlung mittels einer Pfeilanzeige den optimalen Moment, einen anderen Gang einzulegen.

BOSCH SmartphoneHub, available as an option, turns your pedelec into a fully networked e-bike to be part of your digital life: Combined with your smartphone and the COBI.Bike app, SmartphoneHub turns into an intelligent control centre that navigates, records activities and connects with other services and apps. But even without a smartphone, the integrated display shows all essential ride parameters. This gives you maximum flexibility at all times – no matter where your route takes you.

Small, well-connected and trend-setting: Kiox gives sporty, ambitious eBikers access to the digital world via the eBike Connect smartphone app; it even navigates you to your destination. With the robust colour display, you always have an eye on your route and your riding data – and with the separate control unit, you have full control of your e-bike. Kiox records your trip and sends all relevant data, and, using your Bluetooth-connected smartphone, sends it to the eBike Connect online portal. Moreover, you can optimize your workout by connecting it to a heart rate monitor via Bluetooth. This makes Kiox your perfect companion for sporty tours and the Connected Biking adventure.

Nyon connects to the smartphone via the eBike Connect app and exchanges data on routes and activities. As an intelligent guide, the colour display supports you when exploring previously unknown places and, with fitness data, acts as a personal trainer. The all-in-one onboard computer can be operated intuitively and easily via the touchscreen. While driving, it is controlled via a separate control unit. Whether for extended tours or short everyday rides: the robust and perfectly viewable display is ideally equipped for all requirements and all weather conditions.
