The Trek Rail 5 is a best-selling full-suspension electric mountain bike here at Bay Cycles. A powerful and proven Bosch motor, large capacity battery and purposeful suspension fork are fitted to the latest generation aluminium Rail frame. The result is a very capable pedal-assisted electric trail bike.

At the heart of this e-bike is the top spec Bosch Performance CX 85Nm motor. It packs plenty of punch, getting you up near-impossible climbs and battling moorland headwinds with ease. With a high capacity, genuine Bosch battery on board (integrated neatly into the frame but easily removable for charging), a full day out on the bike won’t bring any range anxiety issue either. 625Wh battery capacity is plenty for most riders… even with frequent use of the full-power Turbo mode.

With geometry and sizing lifted from Trek’s wide range of trail and enduro bikes, you’ll find the balanced handling and a dialled fit, boosting your confidence in demanding terrain. A dropper seatpost and tubeless tyres are standard on the Rail 5 – tech that makes a noticeable difference when it comes to performance.

Our Verdict: In the world of premium electric mountain bikes, the Trek Rail 5 is a compelling blend of performance and value. With premium spec Bosch power, a large capacity battery and proven components, this Rail will get you riding further and more frequently.

FEATURES AND BENEFITS OF THE TREK RAIL 5 (GEN 3):

• Alpha Platinum aluminium frame and swingarm, with a magnesium rocker link. The Rail 5 is available in four frame sizes.

• 150mm rear suspension travel paired with a 160mm travel suspension fork on all frame sizes. This is ample travel for trail riding and bike parks, but not too much for more leisure-orientated trips.

• RockShox 35 Gold RL air-sprung fork has an oversized crown to take the extra weight and strain of a hard-hitting electric mountain bike.

• Bosch Performance Line CX is a benchmark motor in the world of electric mountain bikes. With 85Nm of torque it’s powerful, with plenty of punch for the steepest climbs.

• The battery is from Bosch too and has a large 625Wh capacity. It sits neatly into the frame’s downtube but is easily removable with a twist of a key. Charging can be carried out with the battery on or off the bike.

• Bontrager Line TLR 30 aluminium wheelset is tubeless-ready, so ditching inner tubes for a lighter bike, a better ride and fewer punctures is an easy upgrade.

• The wide range 12 speed (1x12) transmission uses Shimano Deore components. These are proven, reliable and affordable to maintain.

• Tektro HD-M7454-piston brakes dish out plenty of power – ideal for dealing with the extra weight of a full-suspension electric bike.
