power and endurance

Going to work and into the field every day? You’re welcome! The XD3 is virtually maintenance-free and technically up-to-date with a carbon belt instead of a chain, a continuously variable transmission instead of a gear shift. With huge energy reserves and the most powerful BOSCH motor of all time.

A slim Supernova lighting system and the modern mudguard luggage rack underline the minimalist design signature of the XD3. Pure understatement from HNF-NICOLAI. Also available as a speed pedelec, i.e. up to 45 km/h.

Bosch Performance CX motor

BOSCH's strongest motor with 85 nm torque

No chain

The GATES CDX carbon belt lasts 10 times longer. It is oil-free and clean, maintenance-free and whisper-quiet.

Stepless transmission

Variable control instead of switching - with up to 380 % transmission range. Fully encapsulated, efficient and 100% maintenance-free.

up to 1125 Wh onboard

Bosch 625 Wh Intube battery with 1126 Wh DualBattery option - endurance for even most extreme adventures.

Available with two motors

With a mere 2.9 kg and a 48 % reduction in size, the current Bosch CX motor is the undisputed benchmark for mid-mounted motors. It accelerates with exceptional power, reacts without delay and now assists with up to 340 % of the pedal force used. Its new transmission concept reduces pedalling resistance to a minimum, providing a natural riding experience even at speeds above 25 km/h or with the engine switched off.

The new Bosch Performance Speed supports up to 45 km/h while being 48% smaller than its predecessor. The low weight of only 2.9 kg and the strong acceleration with 85 Nm torque make it the ideal motor for anyone who needs a little more speed or who is a commuter looking for a replacement for their previous mobility solution.


We install the Intuvia Display from BOSCH as standard on the XD3. Simple, intuitive and safe operation on the separate control unit and a large display make this on-board computer stand out.

Switching between the five riding modes plus push assist, as well as retrieving information such as speed, charging status, distance and much more could not be easier. In addition, the shift recommendation indicates the optimal moment to change gear thanks to an arrow display.

The SmartphoneHub turns your pedelec into a fully connected e-bike – and thus into a part of your digital life: even without a smartphone, the SmartphoneHub offers all the essential functions of a regular on-board computer. The integrated display always shows the most relevant riding data. With a smartphone and COBI.Bike app, however, the SmartphoneHub becomes an intelligent control center with (off-road) navigation, fitness tracker, alarm system, light control, multimedia entertainment and much more. What’s special about this is that all these functions on the mobile phone are operated intuitively with the left thumb, with no need to take the hands off the handlebars. App available for iOS and Android.

Kiox offers all the functions a sports-oriented rider needs. The slim, scratch-resistant colour display is controlled by a separate control unit with tangible pressure points. It provides riding data on speed, personal performance, heart rate, battery charge and much more. With Kiox, you have the essential information at your fingertips.

Connected via Bluetooth with an optional chest strap, you are always informed about your current heart rate and can thus exercise at your best. The Bluetooth Low Energy interface also allows you to download software updates to your onboard computer without a cable connection.

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.


No road too far: the DualBattery option is perfect for touring bikers and long-distance commuters. The combination of two Bosch batteries delivers up to 1,125 Wh and intelligently switches between the two batteries when charging and discharging.


The new Bosch PowerTubes that HNF-NICOLAI installs in the XD3 store a total of 625 Wh of energy. As an Intube battery, they disappear discreetly in the frame of the XD3, where they are safely housed. They are easy to install and remove and can also be charged directly on the bike.


enviolo from Fallbrook Technologies is the standard in continuously variable gear systems for e-bikes.  With a wide gear ratio of up to 380%, the enviolo TR offers ideal comfort for every riding style and terrain.

Matching the philosophy of HNF-Nicolai, the enviolo is completely maintenance-free. Unlike conventional gear hubs, it can also be shifted under load or when at standstill. With these advantages, the enviolo TR is a perfect choice for most e-bike riders. On the XD3 All Terrain, we therefore install the enviolo TR as standard, unless another gearbox is desired.

The maintenance-free, continuously variable high-end automatic transmission enviolo AutomatiQ ensures a ride that is as smooth and comfortable as never before. You choose your pedalling speed and the technology takes care of the rest. So you always cruise along in a constant flow, regardless of the hills or the wind.

Just set your preferred cadence on your Bosch display or via the enviolo app, and the transmission is controlled automatically. If your bike is at a standstill, the starting gear is automatically selected. This way, you always have the optimal gear ratio for maximum acceleration when starting. The optimal gear ratio also extends the range of your e-bike battery.

Speedhub 500 by Rohloff is the gearbox for e-bike pilots with special requirements. The Rohloff Speedhub 500 offers, among other things:

  • the widest gear ratio (526%) – equally suitable for the steepest climbs and the fastest descents
  • the highest efficiency of all gear hubs in the world,
  • a lifespan equal to the mileage of several circumnavigations of the globe, and
  • 14 extremely evenly graduated gears in a hermetically sealed housing.

We install the Rohloff Speedhub 500 as an option on customer request. It is always equipped with the electronic e14 control, which comfortably changes gears within an incredible 180 milliseconds – including motor synchronisation. Even skipping several gears is no problem. And when you stop at the traffic lights, the Rohloff Speedhub 500 automatically switches back to the starting gear.


The RockShox Recon is the ideal suspension fork for the XD3 Premium e-bike: It combines low weight with a highly stiff chassis. The particularly firm RockShox steel uprights allow for a significant suspension travel of 120mm. Thanks to the Motion Control ™ RL damping, the RECON is the new reference for ultimate driving pleasure.


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.


Quiet, maintenance-free and long-lasting. E-bikes with extremely powerful central motors place special demands on their drive system; you can literally watch them wear and tear on conventional chains. Gates has optimized the Carbon Drive CDX specifically for the performance requirements of the e-bike and thus 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. And best of all: unlike the chain, the belt does not elongate with time. No need for re-tensioning.

Available with two lighting systems

The extremely compact housing of the Supernova MINI 2 features the unique Terralux3 lens. The brightness is a full 235 lumens.

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

Not available for the 45 km/h speed pedelec.

The M99 MINI PRO 25 is the first approved headlight with high beam and low beam following 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 the drive home – without dazzling oncoming traffic.

Not available for the speed pedelec with 45 km/h., where the Supernova M99 MINI PRO 45 is fitted as standard.
