Here is a great option for getting into mountain biking without spending a lot of money.
The Kona Mahuna gives you all of the features that you’ll expect to find on more expensive 29″ wheeled hardtails. The frame is made from light-weight aluminum tubing, the fork has a lockout, stout tapered headtube and light aluminum sliders, it comes with mid-level Shimano drivetrain components and reliable Shimano hydraulic disc brakes.
Coming in around $800 dollars, this is a great option for new off-road riders and cyclists who are quickly growing (in size or skill level). The Mahuna comes in sizes that will fit riders under 5’6″ who still want the big 29″ wheels as well as sizes for taller riders.
