Heathen Frame - Purpose Built Aggression

The Forbidden Heathen is a slack, aggressive hardtail MTB frame designed around a 130 mm fork and ONERIDE proportional sizing. Built to be ridden hard or carefully customised, this trail-focused chassis delivers confidence, durability, and balance across a wide range of riding styles. From everyday trail laps to hard-charging descents, the Heathen frame is made to stay composed and predictable when pushed.

Proportional Sizing and Trail Ready Geometry

Sizes S1 and S2 use an MX wheel setup, while S3 and S4 use full 29-inch wheels to maintain consistent front-to-rear centre ratios across the size range. The slack head angle is intentional - paired with a shorter travel fork, it keeps the geometry stable under compression and the handling controlled on rough terrain. Designed for versatility, the Heathen frame is equally comfortable on fast XC rides, technical trails, and loaded backcountry adventures, delivering a clean and mechanically simple ride feel.
