Tested. Certified.
Verifiable.

EU Product Safety: Bikes
EN ISO 4210-1 / 4210-3 : 2023The international bicycle safety standard: frame impact tests, fork fatigue tests, braking and structural requirements. It's the same standard applied to every bike legally sold in the European Union. whatever the brand.
Verify this certificate ↗EU Safety: Electric Bikes
EN 15194 : 2017 + A1 : 2023The European EPAC standard for e-bikes: electrical safety, motor assistance limits, EMC and mechanical integrity. covering our full electric line (EM5, EM6, EM8, EM10, EM19, EC1 and more).
Verify this certificate ↗Factory Quality System
ISO 9001 : 2015Our factory's quality management system is independently audited. design, production and sale of bicycles. with surveillance audits at regular intervals to keep the certificate alive.
Verify via official registry ↗"Direct from factory" doesn't mean "unregulated". It means you get the bike that passed the same tests. without paying for the dealer network on top.
Inside the Testing Center.
Straight from the factory floor. where your frame is built and beaten before it ships.
The material itself.
Our frames use Toray T800 / T1000 / T1K high-modulus carbon. the same fiber classes engineered for aviation-grade structures, laminated for stiffness where you sprint and compliance where you sit.
Threaded T47 bottom brackets (no press-fit creaks) and standard-size sealed bearings. any bike shop on earth can service it, years from now, without depending on us.
Every bike is assembled complete, gears tuned, brakes bled, torque-checked. then partially disassembled only to fit the box. You finish 4 steps at home.
