A slack aggressive hardtail MTB featuring our ONERIDE proportional sizing designed around a 130mm fork. A bike to be cherished or to be neglected. Build it up to beat it down year-round or bless it up with bespoke bits ‘til your friends start asking what you really do for work.
Smaller sizes (S1 & S2) run an MX wheel setup, while S3 & S4 are full 29. This size split allows us to maintain our front-centre to rear-centre ratio and preserve the intended ride characteristics across sizes.
The slack head angle might raise eyebrows for a short-travel bike, but it’s deliberate. A shorter fork keeps the geometry consistent under compression. Meaning the Heathen remains composed when it matters most.
This trail-ready chassis is intended to be a comfortable companion on everything from spicy XC loops to loaded up haul through the backcountry. A metallic mentor ready to guide us back to a life of mechanical minimalism.
