SD3 Urban

from € 3.790,-


The puristic design E-Bike

The SD3 Urban is the sporty urban e-bike that will take you to your destination with ease and elegance. The Bosch Gen 3 motor makes it almost silent and very comfortable, and the powerful 500 Wh battery is discreetly housed in the down tube. The suspension fork and pleasant touring tyres ensure increased comfort and optimum damping.

The stepless Enviolo hub gear, the silent Gates Carbon Drive belt drive and the powerful Magura MT4 disc brakes underline the high quality of this special vehicle. The Wingee mudguard/baggage carrier and the daylight Supernova Mini 2 lighting ensure maximum everyday suitability.

The Bosch active Line Plus

Quiet and comfortable.

The new Active Line Plus is 25% smaller than previous Bosch drive systems and is therefore optimally integrated into the bike frame. The reduced weight and the low centre of gravity ensure safe handling. It is extremely quiet and provides only minimal rolling resistance at speeds over 25 km/h. The intelligent 3-sensor concept provides more than 1,000 measurements per second for an extremely harmonious performance.

Choose your on-board-computer

Design meets functionality: Purion is the minimalist on-board computer for everyone wishing to have a neat look on the handlebar, be it for use in the city or the countryside. You get all important information conveniently at the touch of a button during the ride, with both hands remaining on the handlebar. Five different riding modes give you the correct support in every situation.

Simple, intuitive and safe operation on the separate control unit is the hallmark of this on-board computer.

Not only switching between the five driving modes plus pushing aid, but also retrieving information such as speed, state of charge, distance and much more couldn’t be easier. In addition, the shift recommendation shows the optimum moment to change gear by means of an arrow display.

Kiox offers all the functions a sporty driver needs. The small, scratch-resistant colour display is controlled by the separate control unit with noticeable pressure points. It provides driving data on speed, power, heart rate, battery charge and much more. With Kiox, you have all the essential information at a glance.

Networked via Bluetooth with an optional chest strap, you are always informed about your current pulse range and can therefore train optimally. The Bluetooth Low Energy interface also offers the option of downloading software updates to your on-board computer without a cable connection.

Nyon is connected to the smartphone via the eBike Connect app and exchanges data on routes and activities. The color display acts as an intelligent guide when exploring previously unknown places and with fitness data as a personal trainer. The all-in-one on-board computer can be operated intuitively and easily via the touch screen, while driving it is controlled via the separate control unit. Whether on extended tours or short everyday trips: the robust and optimally readable display is well equipped for all requirements and all weather conditions.

The SmartphoneHub turns the pedelec into a fully networked eBike and part of digital life: Thanks to the Smartphone and COBI.Bike App, the SmartphoneHub becomes an intelligent control center that can navigate, record activities and be connected to other services and apps. The eBike can also be started and controlled without a smartphone, because the display integrated into the SmartphoneHub shows you the most important travel data. So you can stay flexible no matter where your route takes you.

Magura MT4

Magura's MT4 hydraulic disc brake with its precisely amplified braking effect ensures safe riding performance. The adjustable lever width adjustment and ergonomically tuned two-finger brake lever allow precise control of braking performance


Bosch Powerpacks, which HNF-NICOLAI uses for its e-bikes, are lithium-ion batteries with a 500 Wh energy reserve. They are easy to install and remove, and can be mounted directly on the bike as a frame battery. As an intube battery, they disappear discreetly and safely within the frame of the SD2.

Your gear

Enviolo CT

Elegant, reliable, smooth

Enviolo from Fallbrook Technologies is the standard when it comes to continuously variable gears for the e-bike. The Enviolo CT with a wide transmission ratio of up to 330% offers ideal comfort for urban terrain.

In keeping with HNF-Nicolai’s philosophy, the Enviolo is completely maintenance-free. Unlike conventional transmission hubs, it can also be operated under load or when stationary.

Gates Carbon Drive

Silent and longer-lasting – designed specifically for the performance requirements of an e-bike, Gates’ engineers have developed a extremely durable and maintenance-free system. It is 20% lighter and lasts 4 times longer than a well-maintained steel chain. In order to meet the special requirements of human pedal force, an optimal belt drive performance with 11 mm pitch was designed. A polyurethane coating guarantees absolute rust-resistance. The patented system thus ensures interference-free and smooth intermeshing of the teeth with proven Gates durability.

RockShox Paragon

The RockShox Paragon represents perfect technology right down to the very last detail. Generous travel, individual adaptation and a low weight offer excellent performance in the urban area and on challenging trails.

choose your lightning

The new Terralux3 lens is used in the extremely compact design of the Supernova Mini 2. The brightness has been increased to over 15% and is now 235 lumens.

The built-in overvoltage protection in combination with a soft start when switched on ensures a long service life for the Mini 2. Thanks to ingenious light control, the Terraflux lens directs 90% of the light to where it is most needed: on the road.

The M99 MINI Pro 25 is the first approved headlamp with high and low beam according to the new StVZO. High beam is especially essential for off-road use because it improves the illumination of the trail considerably. As the entire environment is illuminated, safety is greatly increased. And after the sporty evening lap, the journey home can be rung in relaxed with the integrated dipped beam – without dazzling oncoming traffic.
