Pivot Mach 4


Meet the Mach 4. This bike may be a bit of a mystery to some. Is it a race bike? A trail bike? Well, it’s both. The Mach 4 straddles the two categories better than anything else out there. Race, and Trail builds are available depending on your preference, with a total of 15 different factory configurations. The bike shown here is a Pro X01 Trail in the XS size. With a 130mm Fox 34 suspension fork, and clearance for up to a 2.6” tire, this is an ideal candidate for a fun and frisky trail bike. Opt for the race build with a step cast 100mm Fox 32 fork and some carbon wheels, and the rest of winning the race is up to you!

Rider Feedback

“I’ve tested a lot of mountain bikes and have always had a hard time finding one that fit, and still rode really well. The Mach 4 felt really nimble and still confidence inspiring. Most importantly it has the most amount of clearance for getting on and off the bike which makes a big difference for me".
