Forbidden Heathen Ti Frameset

A slack, aggressive hardtail MTB featuring ONERIDE proportional sizing, designed around a 130 mm fork. It’s a bike meant to be cherished or neglected. Build it to beat it down year-round, or dress it up with bespoke parts until friends start asking what you really do for work.

Smaller sizes (S1 & S2) run an MX wheel setup, while S3 & S4 roll full 29. This size split preserves the front-centre to rear-centre ratio and maintains the intended ride characteristics across all sizes.

The slack head angle may raise eyebrows for a short-travel bike, but it’s intentional. The shorter fork keeps the geometry consistent under compression, allowing the Heathen to remain composed when it matters most.

This trail-ready chassis is designed to be a comfortable companion everywhere from spicy XC loops to fully loaded backcountry hauls—a metallic mentor guiding riders back to a life of mechanical minimalism.
