If you’re just starting your mountain biking journey and don’t want to break the bank, I have the bike for you. The Mongoose Dolomite is the perfect mountain bike for beginners.

Mongoose is a known and trusted name in the bike world, and the Dolomite is a fantastic example of why. The Dolomite is a fat-tire, aluminum bike.

Fat tire bikes are great for several reasons, but they’re especially good for beginners. The extra tire girth helps you keep your balance when riding off-road.

The extra-wide four-inch tires not only give you better balance, but they also give you better traction on a variety of surfaces. These tires combined with the rear disc brakes make stopping quickly very easy to do.

The sturdy steel frame is resistant to dings and dents but not so dense that it’s impossible to pedal. The bike even comes in three sleek, unisex colors: light blue, navy blue, and red.
