Rail+ 5 Gen 5
Trek
Enduro
Rail+ 5 Gen 5 is an alloy electric enduro mountain bike (2025), by Trek, in the Rail series. This model is best for riders who want a more active, performance-leaning off-road feel, with a setup that gives you a sporty, active riding position, and is aimed at more technical trails and rougher terrain. Its profile is strongest in areas like strong value-for-money versus many similar bikes, a balanced ride feel between comfort and directness, and capable suspension support for rougher terrain. At the same time, the main limitation versus more focused builds is battery range that is better for shorter daily use than long all-day outings.
