Any bike can be adjusted to fit your body, and finding the right bike to fit you perfectly is easy with TPC. Check our women’s bike buyers guide for the deets.

Full Suspension Mountain Bikes

Nothing matches the ride quality of a modern full-suspension bike. Bikes with rear suspension are easy to ride and a blast on any trail. Whether you want a big travel enduro bike or a trail bike, TPC has new and used mountain bikes for sale to fit your fun. Take on the gnarliest descents or do local laps; the choice is yours.

Hardtail Mountain Bikes

Hardtail bikes are exactly what the title says. No suspension moving the rear wheel creates a fast and efficient ride. From cross-country racers to long-travel whips, there is a hardtail made for every rider. 

The best hardtails for XC racing and cross-country bikes are made from lightweight carbon frames with 100-120mm of suspension travel in the fork.

For the more technical trails and an increased fun factor, a bike like the Kona Honzo provide enough travel in the fork to plow over the roughest trails.
