S14 GPI
THE RADICAL GEARBOX DRIVEN TRAIL BIKE
NICOLAI’s interpretation of a radical gearbox driven trail bike is called the S14 GPI. The S14 GPI inspires the rider with its modern and balanced GEOLUTION TRAIL geometry on home trails, in the bike park or crossing the Alps. Agile, smooth running, easy to climb and low maintenance describe this bike best in four ways. You can say goodbye to going ‘over the bars,’ a wandering front wheel on climbs and daily maintenance. The S14 GPI does exactly what a trail bike should do. Two possible wheel sizes, PINION & GATES CarbonDrive (GPI) and plenty of room for water bottles, it is the most versatile gearbox-driven NICOLAI we have ever built.
REINFORCED TUBESET + GUSSETS
NOW EVEN TOUGHER WITH THE ST UPGRADE
We offer the S14 in two versions. The S14 with the suffix ST (SUPER TRAIL) is manufactured with a reinforced tube set and extra gussets. This gives the bike clearance for forks with a length of up to 570mm A2C and a stanchion diameter of 36mm. The standard S14 GPI is not approved for bike park use and the fork length A2C is limited to 550mm. The frame weight increases by about 300gr depending on the frame size for the ST version.
#GEOLUTION trail
MORE SPEED, MORE FUN
The roots of the Geolution concept lie in enduro racing, and even if trends in frame geometries are slowly approaching a similar concept, Geolution can still be seen as a radical design in which performance is top priority. But not all of our customers also put the emphasis here or strive for the top steps at enduro races. They are more interested in a well-rounded bike that can climb well, master any trail and has strong downhill potential.
WHEEL SIZES & SUSPENSION TRAVEL
ONE FRAME, TWO WHEEL SIZES
27.5”, 29”, both? Thanks to the Mutator chips located on the seat stay and 13mm deep (available from RESET RACING or CANE CREEK) lower headset cups to change the stack height, one NICOLAI S14 GPI frame can be configured anyway you choose. Big wheels for big riders, small wheels for smaller riders or a hybrid mix for those who want the best of both worlds: huge front wheel grip, fast speed generation from pumping the terrain and unparalleled cornering response on unknown trails.
TENSION-BAR
ABSORBS LOADS AND REDUCES FORCES
NICOLAI has always been good for the other solution. The tension bar increases the fatigue strength of the frame without increasing the weight.
WELDING TECHNOLOGY
A NICOLAI IS ALWAYS RECOGNIZABLE BY ITS WELDS.
We design a unique jig for every model and frame size. The tubes and machined components are turned and milled as necessary and then mounted in the jig, fitting perfectly together. Then, these parts are tacked together by spot welding. The frame is then welded in several passes by TIG (tungsten inert gas) to reduce distortion. By reducing the distortion as much as possible it improves the alignment of the frame. Our flat, fish-scale welds are time-consuming but ensure that the material is properly fused, improving strength.
Bottle Cage
BACKPACK, HIPPACK OR CLASSIC BOTTLE CAGE?
The decision is yours. The S14 offers space in all frame sizes from size S to size XXL for an easily accessible and protected bottle holder in the main frame triangle.
FRAME SIZE AND TAILORMADE
WE MANUFACTURE YOUR CUSTOM-MADE FRAME
The S14 GPI is manufactured in 5x frame sizes and offers a suitable option for the majority of mountain bikers ranging from 160cm to 205cm.
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.
PINION GEAR
CONTROLLED PERFORMANCE
Many NICOLAI models can be equipped with a Pinion GmbH gearbox on request. The transmission is low-maintenance and optimally integrated into the bicycle frame. The central centre of gravity and the lighter rear wheel bring noticeable advantages in handling, driving dynamics and rear-end performance. The transmission reacts to shift commands at lightning speed.
ANGULAR CONTACT BEARINGS
4 WAY SEALED
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.
Rado
Rear Aligning Dropout
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.
MANUFACTURING QUALITY
Made in Germany
The manufacturing quality itself is not yet an added value for a customer. The following two added values “durability & precise driving characteristics”result from production quality. 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).
7020-T6 Aluminium
ALUMINIUM IS NOT ALUMINIUM
We at Nicolai exclusively use the alloy 7020-T6 (AlZn4,5Mg1) for our frames. Compared to our competitors, who mostly use aluminium 6061-T6, this grade has much better strength values.

BIKE KONFIGURATOR
The S14 GPI can be individually specified as a complete bike in the configurator. Components from manufacturers FOX, ROCK SHOX, INTEND, HOPE, MAGURA, TUNE, CONTINENTAL, SRAM, and LEVELNINE are available.
TRADE AND DISTRIBUTION
NICOLAI frame kits and complete bikes are offered in Germany through our direct sales channel. We offer off the shelf models, or completely customized dream builds with a wide choice of components via our online configurator. Personal discussions and direct contact with customers are our top priority. Abroad, selected partners are available for sales. With our large test bike fleet, we regularly visit bike parks and trail centers around central Europe. Here, potential NICOLAI riders can extensively test our bikes after prior registration and receive individual advice. At the NICOLAI factory we have set up a showroom where all current models are on display. Here, you can also make appointments for personal consultations, test rides, buy bikes directly or pick up pre-ordered bikes.
