The Trek Rail+ 5 Gen 5 is your gateway to full-power e-MTB riding, delivering trail-crushing capability without the eye-watering price tag. Built around Trek’s proven Alpha Platinum Aluminium frame, it’s equipped for enduro terrain with 160 mm of front and rear travel and a geometry that you can dial in to match your style, thanks to adjustable headset cups and suspension leverage rate tweaks.
Up front, the RockShox Psylo Gold RC fork and Deluxe Select+ rear shock soak up the hits while giving you control and stability when things get steep and fast. Powering your climbs is the Bosch Performance Line CX drive unit, pushing 85 Nm of torque and backed by an enormous 800 Wh Removable Integrated Battery (RIB 2.0). That’s plenty of juice for long backcountry missions or back-to-back bike park laps.
Shimano’s Deore 12-speed groupset brings reliable shifting, and powerful 4-piston brakes make sure you can slow things down in a hurry. Mixed wheels—29" up front and 27.5" out back—boost agility and traction where you need it, while Bontrager’s Gunnison Elite XR tyres handle all conditions. A TranzX dropper post and Blendr-compatible cockpit round out a capable spec that’s ready to upgrade as you go.
Whether you’re chasing big days out, bombing descents or exploring new peaks, the Rail+ 5 is built to get stuck in—and go the distance.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
