Dream Trail:

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.

The ‘under the top tube’ mounting screws allow for the attachment of various accessory mounting solutions; pump, tools, a banana, the kitchen sink, go crazy, just don’t hang a water bottle there.

Water Bottle Fitment

Water Bottle Fitment

Even our smallest Heathen frame size can fit at least a full-size 26oz water bottle. Remember, hydration is your friend, but sweaty backs most definitely are not.

Cable Management

Cable Management

Thoughtfully placed external cable mounting points keep hoses and housing in place and rattle free. A dropper post cable port on the seat tube makes for easy routing and a clean finish.
