Mamtor
A versatile road bike for demanding rides.
The Mamtor is the modern definition of a road bike. Built for long days and mixed roads. A club run, a long day in the hills or an unfamiliar road - because not every ride needs a finish line.

Modern road, more capable
Mamtor takes a road bike and adds the clearance and versatility needed for real world riding. Designed for fast group rides as well as long days in the saddle over roads that sit somewhere between smooth tarmac and gravel. It’s not a gravel bike pretending to be fast, and not a road bike that becomes nervous when the surface gets worse.

Speed with versatility
Mamtor shifts the balance. Add tyre clearance, more comfort and adaptability; it is the bike for riders who want a versatile road bike for demanding rides without feeling compromised in any one direction.

ENVE All-Road In-Route fork
Each Mamtor is paired with the ENVE All-Road In-Route fork, chosen to match the frame’s balance of speed and tyre clearance needed for real-world riding. The result is a road bike that can move beyond the tarmac without losing its road-bike character.

Slim, wide-set seatstays
Mamtor uses slim, wide-set seatstays to give tyre clearance while maintaining a double-diamond construction. It’s a simple detail that balances clearance, comfort and stiffness, while giving the bike a distinctive rear profile.

Integrated mudguard mounts
Low-profile mudguard mounts are integrated into the dropouts and fork, giving Mamtor year-round practicality without cluttering the frame. When guards are not fitted, the mounts stay quiet and discreet.

Relaxed geometry and generous tyre clearance bring speed and control together. Carefully selected Columbus steel and 3D-printed details give the Mamtor a considered balance of weight, strength and versatility. It’s a bike built around the simple pleasures of riding. Fast when you want it, and holds steady when the surface doesn’t.
