Myka Disc 650b | Specialized.com

Whether you're just starting to get your wheels dirty, or you already revel in mixing it up on every ride, the Myka Disc 650b checks all of your required boxes for a fun, capable mountain bike. Not only is the ride dedicated to rolling over rough sections, but every facet of the bike is also specifically tailored to women, from the ultra-low standover to the saddle. And with the added benefit of mechanical disc brakes, you'll be inspired to seek out dirt with a level of confidence like never before.

A1 Premium Aluminum frame construction ensures that the bike is lightweight and durable, while the Women's Sport Trail 650b Geometry and 650b wheels make for an extremely low standover and heightened sense of control to accommodate more women's body types and experience levels without sacrificing trail performance or handling.
SR Suntour 650b fork features 75mm of smooth suspension travel to effectively smooth out bumpy terrain. And to make sure of it, the fork carries our Women's Custom Tune that was developed specifically for women, so it's guaranteed to perform the task at hand on every ride.
Shimano Tourney 7-speed rear derailleur has a wide gear range to make climbing hills a breeze.
