Hardtail Enduro Hooligan


On-One DeeDar

There's a beautiful simplicity to the DeeDar- it's simply made for smashing your local trials and favourite Enduro style tracks. Truth be told the DeeDar is a bit of a monster, We've based it on the geometry of modern full suspension Enduro rigs but simplified everything by keeping it real, steel, and hard in the tail.

The DeeDar is uncomplicated and fuss free, it's the bike that we wanted to ride for ourselves and it's now available for you to own as well. If you ever fancied a hardtail but held back because you thought it might not be capable enough now is the time to dip your toe in the water. With 27.5" wheels, ready for 140mm of front suspension and sporting Stealth Dropper routing the DeeDar is ready for anything- are you?
