Hardtail Mountain Bikes

Hardtail or Hard Tail it doesn't matter how you spell it there's an elegant simplicity about these bikes; start with the classic double diamond bicycle frame layout, add in a front suspension fork to help tame the trails and smooth your way over rough terrain- and you're done.

For many recreational, off-road cyclists front suspension is all they need. A fork with 120-140mm of travel will soak up an awful lot of lumps and bumps and smooth out all but the most challenging terrain. Keeping the rear end of your bike rigid keeps you connected to the dirt. You can feel every twist and turn of the trail and immediately respond to changes in terrain. It's a more connected riding experience that puts you in direct contact with the trail and that's why many cyclists prefer a good Hardtail mountain bike to the isolated feeling of full suspension mountain bike.

Planet X has a huge range of Hardtail mountain bikes from our On-One and Titus brands. Explore them and find the right bike for you.
