BOSCH PERFORMANCE POWER

PERFORMANCE LINE

With its sporty 65 Nm of torque and plenty of power, the drive unit always delivers the right support at the right moment, even in the mountains. Das Fahrgefühl bleibt natürlich, im Off-Modus und über 25 km/h fast ohne Tretwiderstand. The five driving modes make every ride a pleasure. And all of this is virtually noiseless thanks to the innovative noise-optimised transmission, making the Performance Line one of the quietest powertrains in its class.

GATES CARBON DRIVE

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.

POWERTUBE 500 WH

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.

Your gear box

Today, enviolo from Fallbrook Technologies is set to become the standard in continuously variable gears for bicycles and e-bikes. With a wide transmission ratio of up to 380%, the enviolo TR offers ideal comfort for every driving style and terrain.

In line with HNF-Nicolai’s philosophy, the enviolo is entirely maintenance-free. Unlike conventional gear hubs, it can also be shifted under load or at standstill.

available with two lighting systems

The exceptionally compact design of the Supernova MINI 2 features the unique Terralux 3 lens. The brightness is a total 235 lumens.

The built-in overvoltage protection combined with a soft start upon switch-on ensures a long lifespan for the MINI 2. Thanks to sophisticated light guiding, the Terraflux lens directs 90 % of the light to where it is needed most: the road.

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.

Available with the following command centers

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.

The Intuvia, optionally available for the SD3, offers simple, intuitive and safe operation on the separate control unit.

Not only is it easy to switch between the five riding modes plus push assist, but also to call up information such as speed, charging status, distance and much more. In addition, the gearshift recommendation shows the optimal moment to shift into another gear using an arrow display.

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.

Uncompromising quality

A timeless and reduced design has always been at the heart of our robust and high-quality bikes. Today, HNF stands as a symbol for the pioneering achievements that drive our advanced drivetrain concept: We preferably combine the powerful and indestructible Bosch motors with a durable belt drive and a continuously variable transmission. This combination, which we first introduced in 2015 with the XD series, is today considered the gold standard for maintenance-free operation across all manufacturers. Since 2022, we have also been adding high-quality chain drives and gears to our product range, enabling us to serve broader market segments.

ROCKSHOX PARAGON

The RockShox Paragon stands for perfect technology down to the smallest detail. Large suspension travel, individual adjustment and low weight offer excellent performance in urban areas and on demanding trails.

CLARKS M2

The M2's dual-piston calipers provide excellent braking performance in all conditions. Supported by a slim and compact lever design, this braking system offers exceptional and consistent reliability in both dry and wet driving conditions.
