TRAIL BIKE IN PERFECTION
The ION-G13 was our first 29er Trailbike with GEOLUTION geometry – downhill as well as uphill more confident than anything ever before. With the ION-G13 GPI, which is new for 2018, we have added to that. The perfect integration of the Pinion transmission into the frame and the Gates CDXTM belt not only makes the Fully the ultimate carefree trail bike, where maintenance costs are virtually zero. At the same time, the centralized mass distribution also optimizes handling and suspension performance. Less unsprung mass ensures more sensitive and better suspension. The ION-G13 GPI is still a trail bike, with which you can heat over your home trails and enjoy long trail & adventure tours… but that’s only part of the truth. With the incredible transmission ratio bandwidth of 600% in the Pinion P1.12 transmission (optionally also P1.18) and the powerful GEOLUTION geometry, you can push the limits of mobility uphill. Downhill, the high running smoothness and solid ground position ensure unparalleled safety even in the trickiest passages. The ION-G13 GPI is the ultimate trail bike technology in perfection.

For each model and each frame size we have designed its own welding device, a so-called frame gauge. Here, the pipe sets and the turned and milled parts fit together precisely, in order to be tacked by our welders at precisely defined points and in exact sequence, and then welded in several passes by TIG (tungsten inert gas) in order to minimize distortion and distortion. Our evenly flat scaled welds are produced by a very slow welding speed and, unlike with applied seams, cause a deep fusion of the material.
ANGULAR CONTACT BEARINGS
The rear triangle of a full suspension bike is not a statically rigid component and is exposed to extreme loads during driving. Critical points are the ball bearings, which ensure low breakaway torque and optimum response of the chassis. In order to extend the maintenance intervals of the frame, Nicolai products rely exclusively on full complement, double-sealed ball bearings.
TOPOLOGY OPTIMIZED STRUCTURE
A bicycle frame and its components are exposed to extreme forces during use. In order to develop a durable, robust but also lightweight bicycle frame, all components are designed at NICOLAI GmbH using topology optimization.
So that you can hit every lane on the trail, we mount a form-fit sliding, exchangeable dropout for track and camber adjustment on all frames. Due to the differently milled, right dropouts for adjusting the lintel, the rear only needs to be slightly readjusted after installation. This takes the strain off the material. The respective lintel height is milled into the RADO with the digits 0, 1, 2 or -1 and -2. After the toe and camber have been set, the RADO is fixed ex works with a pin. This makes the original setting easily reproducible during replacement. This is the only way we can guarantee that NICOLAI products work precisely on the track.
With the ET-Key, the range of application of the frame can be adjusted in a few easy steps. The ET-KEY changes the kinematically active length of the compression strut. With the models ION-G13, ION-G15 and ION-G19 you can adjust the steering angle and the bottom bracket height, e.g. for a visit to the bike park or a steeper trail. With an ION-G16, the shock absorber length can be adjusted via the ET KEY and thus the spring travel can be changed. The damper length/stroke can be changed from 216x63mm to 222x70mm. As a customer you can fully rely on the performance of your Nicolai frame. In the depth of the technology we do our homework and with the introduction of the ET-KEYS we have introduced a robust and simple adjustment technology.
The MUTATOR is a newly developed component on the rear swing arm, which combines many functions in a single component: The mutators are available in different lengths. In this way, only by replacing a mutator can the length of the swingarm “grow with” the frame height according to our GEOLUTION concept. The rear suspension length of the EBOXX E-MTB can also be varied according to customer preference.
Only if the welds are welded deep into the root and have no notches, a bike frame can withstand the impacts from the ground for many years without breaking. Precise riding characteristics are achieved when the rear wheel is precisely straight to the front wheel and even a layman notices that an oblique bike rides strangely (but usually he thinks it’s because of his riding ability).
“GEOLUTION is the geometry concept on which all current Nicolai models are based. In the last 3 years GEOLUTION was developed by NICOLAI and the suspension specialist Chris Porter. The concept is based on the realization that a longer wheelbase, a flatter steering angle and a steeper seat angle make the bike faster, smoother, more climbing and safer. The geometric relationship between wheels, steering angle, and weight distribution between wheels are the decisive factors for good handling. The relationship between saddle, crank and rear wheel axle are the decisive factors for a good climbing behaviour of a bike. The GEOLUTION concept combines perfect handling with optimum climbing behaviour. The rider is integrated into the bike through the long reach, the steep seat angle and the long wheelbase, so that the centre of gravity lies optimally between front and rear wheel axle. All GEOMETRON models are driven with short stems, so that the driver has a relaxed, sporty sitting position despite the long top tube.
10 YEARS SPARE PARTS AVAILABILITY
If after a few years of hard work a bearing on a Nicolai frame needs to be replaced, a RADO needs to be replaced due to a fall or a frame needs a new coating, the NICOLAI service staff is the right contact. Since we at NICOLAI manufacture all small parts on our machines, we can also produce spare parts for older models if required. We therefore guarantee spare parts availability of at least 10 years for all Nicolai products.
This product is produced by order , please contact our customer service for details and lead-time. Under normal circumstances, the lead-time takes about 180 days.
