NICOLAI has completely revised the chassis for the 2022 EBOXX. For the elaborate frame construction, the manufacturer traditionally uses 7020-T6 aluminum, which has an approximately 30% higher tensile strength and an approximately 20% higher elastic limit compared to the 6061-T6 alloy commonly used in bicycle construction. The argument of sustainability in terms of recycling and the goal of a complete circular economy are also important arguments for the manufacturer. Production of the NICOLAI EBOXX series takes place entirely in the company’s own factory at its German site in Mehle, Lower Saxony.
A brand new feature for the EBOXX is a completely CNC-milled head tube, in which the internal cable ports are integrated. Compared to the turned and butted head tube of the previous model benefits significant weight savings and gains in stiffness and aesthetics. The down tube, an extruded multi-chamber profile with the battery opening underneath, has also received a redesign to accommodate the larger 750Wh battery. The previous extrusion is also updated with a lighter design. The rear end has also been redesigned: the ‘Hollow-Milled’ component is now used as the compression strut yoke, again combining weight savings with stiffness gains.
Hollow-Mill is a technology NICOLAI uses in the construction of highly stressed, complex and voluminous components to achieve maximum durability with minimum weight. Hollow-Milled parts are manufactured by NICOLAI on state-of-the-art 5-axis CNC machines and are hollow milled from the inside. During design, NICOLAI uses FEM software (Finite Element Method) to simulate the loads occurring in real-world use to optimize the shape (topology) of these components. Topology optimization makes critical stress areas of the design visible. These can be strengthened by adding material, while unnecessary material can be saved in low stress areas.
These redesigns of the 2022 EBOXX frame have resulted in a weight saving of over 500g compared with the previous model. This effectively compensates for the additional weight of the larger 750Wh BOSCH Smart System battery. When using the 625Wh battery on the EBOXX models with a 4th generation BOSCH Performance Line CX drive combined with the electronic ROHLOFF E14 shifting system, the total bike weight can be reduced by half a kilo.
The new frame has clearance for 203mm brake discs. NICOLAI has revised the rear for this purpose and designed new sliding dropouts for tensioning the Carbon Drive belt, whose integrated brake mount has been reinforced with a torque support to compensate for higher braking forces.
NICOLAI points out the outstanding durability and extreme load capacity of its EBOXX models by granting a 5-year warranty against material failure: frame breakage even for competitive use, under the toughest riding conditions and with a total weight limit of 130kg. NICOLAI further backs its frame up to 150kg, however, the suppliers of most components do not follow suit.
2022 EBOXX Models at a Glance
With the introduction of the new 5th generation BOSCH drive, the Performance Line CX Smart System, e-bike manufacturers like NICOLAI, who have relied on the electronically controlled ROHLOFF E14 hub gears until now, will be faced with an ultimatum because the 2022 BOSCH Smart System does not support the E14 software at this time. Choose between the latest BOSCH technology in combination with a mechanically controlled ROHLOFF hub – or the electronic E14 Speedhub with the compatible 4th Gen. Performance Line CX drive? NICOLAI replies with a clear: “Both and!”
The 2022 EBOXX is offered in four variants, each with the 5th Gen. BOSCH Performance Line CX Smart System drive installed and equipped either with a derailleur or a mechanically shifted ROHLOFF Speedhub. Two EBOXX variants, on the other hand, are equipped with the 4th Gen. BOSCH Performance Line CX drive and a compatible electric E14 Speedhub.

G1 EBOXX QLF
GT1 EBOXX QLF
The suffix in the model name indicates which drivetrain is used. E14 stands for the electronically switched ROHLOFF hub gears in combination with a 4th Gen. BOSCH drive. The EBOXX models with the addition MR14 are equipped with the mechanically shifted ROHLOFF 14 Speedhub. The addition QLF stands for the variants with derailleur gears. The MR14 and QLF models are offered by NICOLAI with the 5th Gen.BOSCH drive.
The beginning of the model designation G1 or GT1 indicates the geometry and the focus of use. G1 stands for the radical Geolution geometry on which the human powered NICOLAI competition enduros are also based. GT1 stands for Geolution Tour, a more comfortable touring geometry. We will go into more detail about the different geometry concepts and their characteristics right after this overview.
The 4th generation BOSCH Performance Line CX drive and the 5th generation BOSCH Smart System drive use the same motor with the same performance parameters. The differences between the two systems are mainly in the periphery, i.e. the controls, the interfaces and the battery. We examine these aspects in detail below and present the new features of the Smart System.
G1 EBOXX – Geolution, Exclusive Enduro Competition Geometry. Geolution is a unique geometry concept developed by NICOLAI in cooperation with Chris Porter from the English brand GEOMETRON. Based on the idea that a longer wheelbase, a slacker steering angle and a steeper seat angle make the bike safer, faster, smoother and easier to climb. Climbing characteristics are improved because the steep seat angle and long front end position the rider centrally preventing front wheel lift on steep climbs.
The long wheelbase and a slack steering angle, on the other hand, allow for high downhill and cornering speeds and prevent an ‘over the handlebars’ feeling on steep downhills. The central seating position and center of gravity ensures optimum load distribution between front and rear wheels. This improves control in dynamic riding situations and overall handling.
GT1 – Geolution Tour, Enduro Geometry Tuned for Touring.
NICOLAI explicitly emphasizes that its Geolution models are perfectly suitable for beginners, but also takes into account that not everyone likes a sporty and forward riding position on the bike or wants to compete. The Geolution Tour geometry is precisely intended to appeal to this clientele. With a significantly longer head tube and a steeper steering angle, the geometry becomes more moderate and comfortable. The seated position becomes more upright, the bike reacts with more agility and is easier to handle. With the Geolution Tour concept NICOLAI wants to offer a universally usable bike that can climb well, masters every trail and has a strong downhill potential, but also on long tours, everyday use or as a commuter provides a comfortable position and relaxed rides.
The NICOLAI models G1 EBOXX MR14, GT1 EBOXX MR14, G1 EBOXX QLF and GT1 EBOXX QLF are equipped with the BOSCH Performance Line CX Smart System, which has been completely revised in its 5th generation. The base of this system was designed for future expansion and is formed by all the BOSCH modules installed on the NICOLAI EBOXX: The 5th Gen. Performance Line CX motor, a new Connect standard for charging socket and charger, the 750Wh battery, the new BOSCH LED remote control unit and a completely newly developed Kiox 300 display.
The performance parameters of the motor have not changed. With its 85Nm of torque, it remains the most powerful drive in the BOSCH line-up and supplements up to 340% in addition to human power. This provides strong torque in all riding situations and maximum power, especially at low cadence, which makes mastering technical passages and standing starts on steep sections noticeably easier. Now with 750Wh compared to 625Wh at the 4th Gen. Drive, this 20% gain in battery capacity increases the range accordingly.
For a longer range, the EBOXX models with the 4th Gen. BOSCH Performance Line drive a secondary 625Wh battery which can be carried with NICOLAI’s optional custom quick mount on the top tube. For the 5th Gen. BOSCH models, however, this option does not exist due to the longer 750Wh battery.
The 2022 BOSCH Performance Line CX Smart System establishes a new standard with its components designed for modularity and renounces downward compatibility. Smaller batteries, previous chargers or the Niox display can no longer be used here. However, an expanded range of BOSCH components can be expected in the near future.
All EBOXX models are available either as a frame kit or complete bike with various features and options. For example, you can also choose ‘SUV’ tires, if the bike is to be used mainly for touring on paved roads but also occasionally off them. The SCHWALBE Jonny Watts tires have been developed specifically for this purpose. On hard surfaces they roll particularly easily and quietly, but also still offer very good grip when it goes off-road.
For those who want to expand the range of use of their EBOXX bike, for example, to use it for commuting, as an adventure bike or daily ride, NICOLAI offers an “Explorer Kit”, which consists of mudguards, luggage rack and lighting system. This makes the bike more suitable for everyday use and complies with the requirements of the StVZO. The Explorer Kit is optimally adapted for use on NICOLAI EBOXX bikes and consists of high-quality, perfectly fitting add-on parts. It is available as a complete set or in the form of individual components and can be assembled in advance or ordered for retrofitting.
Exclusively for EBOXX complete bikes with Rohloff gears and Explorer kit, there is also an S-pedelec option that allows motor assistance up to 45 km/h. This variant is subject to registration and therefore does not allow any deviation from the equipment listed in the vehicle registration document.
For a complete overview of all EBOXX variants and options, the current equipment lists are attached to this PM.
Geolution was developed by us in cooperation with Chris Porter from the English brand GEOMETRON. The concept is based on the idea that a longer wheelbase, a flatter steering angle and a steeper seat angle make the bike faster, smoother, easier to climb and safer. Climbing characteristics are improved because the steep seat angle and long front end position the rider to prevent the front wheel from rising on steep climbs.
The long wheelbase and a flat steering angle, on the other hand, allow for high downhill and cornering speeds and prevent a rollover feeling on steep downhill sections. The central seating position and the central center of gravity also ensure optimum load distribution between the front wheel and rear wheel. This increases the rider’s control in dynamic riding situations and improves the bike’s overall handling.
Geolution models are ridden with the shortest possible stem. This gives the rider a moderate, sporty riding position despite the long reach and allows optimum grip on the front wheel.
