As the worlds biggest cycling trade show, Eurobike is a chance for brands to show off their stock bikes and parts. But one of the joys of wandering the shows massive and many halls is discovering bikes you'll struggle to see elsewhere.These include bikes from bespoke builders, unreleased models from big brands and race bikes professional riders have specced out to their hearts (and sponsors) content.While Euorbike 2024 has drawn to a close, we thought wed bring you four of our favourite custom bikes from the show, to give you a taste of what was on display.Amapola Cycles technicolour race bikeThe Amapola Cycles race bike at Eurobike 2024. - Jack Luke / Our MediaWhatever your feelings about custom-painted components, theres no denying that this Amapola Cycles race bike makes a strong case for a matching cockpit.Its hard to imagine a technicolour paint scheme like this not spilling over the bar and stem.The Deda stem and handlebar are painted to match the frame. - Jack Luke / Our MediaAmapola Cycles bikes are handmade in the Netherlands. This steel bike is fillet brazed and uses a mix of Dedacci, Reynolds and Columbus tubes for a superlight build.The frame is completed with a carbon fibre fork from Columbus, which like the frame routes everything internally.Elsewhere, there is an integrated headset and a T47 bottom bracket, completing this modern steel road bike.The technicolour steel bike is complete with Shimano wheels and Continental tyres. - Jack Luke / Our MediaThe build is completed by components from a range of brands. The painted stem and bar are from Deda. The bike has Shimanos Ultegra groupset and C60 wheels wrapped in Continental tyres. The seatpost is supplied by Thomson, and the saddle and handlebar tape are from SQ Lab.Giants prototype Trinity TT bikeThe latest Giant Trinity broke cover at this year's Tour de Romandie. - Jack Luke / Our MediaEurobike can often feel like a treasure hunt. Buried in its labyrinthine halls are yet-to-be-released groupsets, wheels and bikes, all waiting to be photographed and written about or at least thats our view. The brands may have a different opinion.One example of an unreleased bike that wasnt exactly hiding at Eurobike 2024 was Giants prototype Trinity time trial bike, dressed in custom colours for Jayco AlUla.This new Trinity isnt the biggest secret in cycling Jayco AlUlas Luke Plapp raced it at the Tour de Romandie in April but its certainly a latecomer to road cyclings disc-brake era.The new Trinity has deep, aero forks. - Jack Luke / Our MediaWith time trial bikes being updated less frequently than racing road bikes, the Trinity was one of the last existing models from a big brand to have rim brakes.There are different ways of looking at this switch to disc brakes. The debates around the aerodynamics of disc brakes may have been put to bed. Developments in bike tech, such as disc-brake specific groupsets and wheels, could have forced Giants hand. Or maybe the improved braking and cornering that come with disc brakes are just too valuable when racing against the clock.Whatever the explanation, the Trinity was getting old and this new version brings it up to date. Well have to wait for the official release to find out more.A Sturdy Cilla with 3D-printed titanium partsSturdy uses 3D-printed titanium across the Cilla gravel bike. - Jack Luke / Our MediaSturdy says its new Cilla is an adventure-focused gravel bike, sharing its DNA with the brands Fiadh but with extra clearance, accepting tyres up to 50mm wide.The bike is named after founder Toms late mother and is a tribute to her curiosity for the great British countryside and love of the natural world.The bike has 3D-printed cranks. - Jack Luke / Our MediaLike all of Sturdys bikes, the Cilla uses titanium tubing and 3D-printed titanium parts. The 3D-printed parts include the fork, bar, seatpost and cranks. But look closer and youll spot more even the rotor lockrings are printed titanium.The bike is covered in neat details, including the titanium thru-axle and the brand name on the chainstay. - Jack Luke / Our MediaThe advantage of building a titanium gravel bike such as this is the geometry of every Cilla is customisable.While its billed as a titanium gravel bike, Sturdy says the geometry can be tweaked to suit any riding style and that you can also think of the Cilla as an all-road, cyclocross or touring bike.Anne Terpstras Ghost LectorThis is the Ghost Lector Anne Terpstra raced to victory at the Cape Epic. - Jack Luke / Our MediaAlongside teammate Nicole Koller, Anne Terpstra won the 2024 Cape Epic racing this custom Ghost Lector.As you might expect from a bike ridden at the Cape Epic, Terpstras Lector has a top-spec build.Terpstra's bike is fitted with Bike Ahead Composites' six-spoke, monocoque wheels. - Jack Luke / Our MediaThe cross-country mountain bike has RockShox Flight Attendant throughout, including the front fork, rear shock and dropper post.The Lector also has SRAMs top-spec XX Eagle AXS transmission with a power meter crankset thrown in for good measure.There is a smaller bottle mounted under the top tube to fit in the small frame. - Jack Luke / Our MediaThere are also SRAM Level Ultimate Stealth brakes, whose silver bodies are nestled next to Terpstras custom grips emblazoned with her name. One of the most eye-catching features of Terpstras bike is the Bike Ahead Composites six-spoke, monocoque wheels. These appear to be the Biturbo RS wheels, which are made in Germany and cost just over 3,000.The bike still has Terpstra's Cape Epic race number. - Jack Luke / Our MediaAs is a bit of a trend for pro bikes at Eurobike, the bike hadnt been cleaned. Instead, it had all the dust and muck of racing on show. It still had Terpstras bottles in place, too, including a smaller top-tube mounted bottle to fit inside the small frame.
