Quirk Cycles: London Steel Bikes Shaped by Distance, Fit and Terrain
Quirk Cycles builds handmade steel bicycles in Hackney, London, with a range that separates fast road riding, versatile all-road use and gravel adventure. Its appeal lies in the connection between the framebuilder’s experience and the rider’s choices: geometry, components and finish all matter alongside the intended route.

A framebuilder’s perspective on long-distance riding
Rob Quirk has designed and built bicycles in Hackney since 2015. His background in art and architecture informs his interest in materials, objects and how people relate to them. According to Quirk’s own account, ultra-distance events including the Transcontinental, Silk Road Mountain Race and Atlas Mountain Race also helped shape the business. Different routes called for different frames, creating a practical foundation for continued development.
The resulting identity combines traditional frame material with contemporary construction details. Quirk’s current range overview identifies selected Columbus tubing, 3D-printed components, UDH dropouts and a hidden wedge seatpost clamp. Those details give buyers something more concrete to examine than paint alone: how the frame is assembled, how components integrate and which riding purpose the design serves.
Three models with distinct priorities
Choose by surface and riding ambition
The Durmitor is Quirk’s race-road offering. The manufacturer describes geometry centred on fast road riding and lists clearance for 35c tyres. It is the logical starting point within the range for riders whose priorities are hard road efforts and fast group rides.
The Mamtor broadens the road brief. Quirk specifies relaxed geometry, 40c maximum tyre clearance and integrated mudguard mounts, positioning it for long days and roads that vary between smooth tarmac and rougher surfaces. Compared with the Durmitor, its stated emphasis gives riders more scope to prioritise mixed-road versatility.
The Kegety moves into gravel racing, adventure and loaded routes. Its listed 50c clearance, dedicated 1x drivetrain layout and mudguard mounts distinguish it from the two road models. For buyers comparing these families, tyre room and drivetrain compatibility are useful first filters before considering colour or build level.
Personalisation starts with fit
Quirk offers six standard sizes alongside custom geometry. Its customisation guidance recommends using a trusted bike fitter to help decide which approach suits the rider. Standard colours and custom finishes provide further choice. The useful buying question is therefore how closely an existing size meets your fit requirements, followed by which model best matches the surfaces you regularly ride.
