Forbidden launches two titanium hardtails

Meet the newest members of Forbidden’s Bicycle Witchcraft family, the Puritan and the Heathen. Two proportionally sized titanium hardtail frames. While these bikes do not employ an idler or a high-pivot layout, they are all metal and all Forbidden. This limited run of titanium frame kits are designed to be ridden hard and kept for a lifetime.

The Puritan

A gravel bike? A 90’s mountain bike? Who cares. It’s a proportionally sized titanium ATB (all-terrain bike) built for loaded up long hauls, mid-commute singletrack sessions, and whatever else you think you shouldn’t be doing on a
700c bike.
With room for up to 700c x 2.0″ (50 mm) tires and Forbidden’s ONERIDE proportional sizing, the Puritan
blends gravel efficiency with comfort and stability. Load it up with bags to get lost in the woods, or pedal it to the pub. We don’t make the rules.

The Puritan is purpose-built to run a flat bar and a 60mm stem. Yes, you can build it with drop
bars, but it will stretch out the rider triangle. Sorry, not sorry. This bike is unapologetically flat-bar
first.

A slack aggressive hardtail mountain bike featuring Forbidden’s 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 and S2) run an MX wheel setup, while S3 and S4 are full 29. This size split maintains Forbidden’s 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.
