Custom-built mountain bikes hold a special fascination because they are far more than just pieces of sports equipment. They reflect their owner’s character, preferences and aspirations. Every component chosen tells a story – of uncompromising performance, technical sophistication or a love of detail.
It is precisely this combination of function, craftsmanship and personal expression that makes custom bikes the hidden stars of every bike show. At Eurobike, too, we kept our eyes peeled for some truly special dream builds.
For a hobby project undertaken by three friends, the Unchained prototype looks absolutely brilliant. The bike combines a high-pivot four-bar rear suspension with a Pinion gearbox and a low-maintenance Gates belt drive.
The frame, made from 7075 aluminium, looks particularly stylish; its tubes and sleeves are not only bonded but also bolted together using fine-pitch threads.
With 170 to 175 millimetres of suspension travel, variable rear-end stiffness and a geometry designed for long descents, this bike is aimed at enduro riders who prefer low-maintenance aluminium bikes.
The young brand Stabelead was already turning heads at last year’s Eurobike. The company is a spin-off from the photography and film industry. Through this brand, the Chinese technology group Tilta is applying its expertise in the manufacture of camera systems to bring its technologies to mountain bikes.
The entire bike has been completely reimagined: from the frame, through the upside-down suspension fork and the carbon shock absorber, right through to the disc brakes and accessories, Stabelead has developed its own designs. All the components on display are still at the prototype stage – they are not yet available in shops. The
Asa Vermette is regarded as the undisputed rising star of downhill cycling. At the TRP stand, fans were able to catch a glimpse of his personal training bike. It is a custom build based on the much-talked-about Frameworks frame.
In theory, even ordinary folk can buy the aluminium frameset for €3,568.95. However, it is currently sold out. The pro-spec build includes: a Fox Factory suspension fork, Enve carbon wheels, TRP Evo Pro brakes and a TRP Downhill drivetrain with exceptional titanium cranks from 5DEV. Vermette also uses an O-Chain system and components from Burgtec.
SB Projects is renowned for its unique custom bikes. On YouTube, their dream builds regularly captivate thousands of viewers. The carbon chassis is a bespoke design for the Mahle M40 motor. This little powerhouse delivers up to 105 Newton metres of torque and 850 watts of assist power.
The motor is said to weigh 2.5 kilos and draws its power from an 850-watt-hour battery. A special paint finish has been applied to the frame for SB Projects. The build is rounded off with a Fox Factory suspension system and Shimano XTR brakes. The mullet bike, with 160 millimetres of front suspension travel and 150 millimetres at the rear, is said to weigh in at around 21 kilos.
Hope is best known for its intricately machined aluminium components. With the new HB912, however, the British company has impressively demonstrated that it has also mastered carbon fibre. The trail bike offers 120 millimetres of rear suspension travel and 130 millimetres at the front.
Thanks to an adjustable headset, the steering angle can be set between 65 and 66 degrees to suit your preference. The frameset is available for 3,950 British pounds, whilst the complete bike starts at 7,950 British pounds.
The in-house design team were given free rein to let their creativity run wild on the show bike on display. The transparent carbon finish is particularly eye-catching, creating a striking contrast to the polished, CNC-machined components in classic Racing Green.
