Used For
Trail Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike.

Suspension:
Hardtail

Suspension
Hardtail As the name suggests, hardtail bikes feature a rigid frame with front suspension only. This means that the rear wheel lacks any form of suspension, hence the term "hardtail."
Hardtail mountain bikes are renowned for their efficiency in transferring power from the pedals to the rear wheel, making them excellent choices for climbing and maintaining speed on smoother trails or paved surfaces.
