Trek Top Fuel 5 Gen 4 Mountain Bike 2025

The Top Fuel 5 Gen 4 is a nimble alloy trail bike that's ready to hammer up climbs and hold its own on descents – all without breaking the bank. It offers 130 mm of front and 120 mm of rear suspension that gives you just enough squish to soak up chatter without draining your power on all-day pedal fests. It comes equipped with a RockShox suspension package and Shimano Deore group set that gives you everything you need to rip in an economical package.
