Trek's Powerfly+ 4 800Wh strikes an impressive balance between trail capability and value, delivering adventure-ready performance that makes mountain biking more accessible to riders of all abilities. This hardtail e-MTB combines proven components with Trek's engineering expertise to create a bike that encourages exploration whilst maintaining the reliability needed for regular trail use.
The benchmark drive unit built into the Powerfly+ 4 is the powerful Gen 5 Bosch Performance Line CX motor. This is Bosch's latest motor, which provides intuitive assistance that responds naturally to your pedalling and delivers the climbing power and acceleration needed to tackle demanding terrain with confidence. All while maintaining the natural feel that makes every ride engaging and rewarding. The Performance Line CX motor gives 85Nm of torque out of the box but can be tuned all the way up to 100Nm and 750W of power using the Bosch eBike Flow app on your phone or tablet. With the Bosch Purion 200 remote on your handlebar you have control right at your fingertips, so you can change assistance levels without taking your hand away from the grips.
Bosch is renowned for quality and energy efficiency, but even so, with a powerful motor you need plenty of 'juice' to feed it. On this model Trek has not pulled any punches and has included a top end 800Wh Bosch PowerTube battery, giving you impressive range for off-road fun all day long even when utilising higher assistance levels, as well as supporting extended adventures on multi-day trekking with lower assistance. Bosch's smart system integration provides seamless communication between components, whilst the removable battery design allows for convenient charging and potential battery swapping on longer expeditions. The Removable Integrated Battery (RIB 2.0) design makes it easy to remove your battery for more convenient charging or travelling, and you don't have to worry about dropping it thanks to a secondary safety catch.
Want to take your ride even further? Pair an optional 250Wh PowerMore range extender battery with your bike to chase your most epic adventures.
Trail comfort and control come courtesy of the SR Suntour XCR 34 suspension fork with 100mm of travel on smaller frames and 120mm on larger sizes. This air-sprung fork features hydraulic lockout and reliable damping that enhances rider confidence while reducing fatigue on longer rides across varied terrain.
Gear changes are handled smoothly by Shimano's reliable CUES 10-speed drivetrain, featuring the U6000 rear derailleur paired with an 11-48 tooth cassette. This combination provides a wide range of ratios for both steep climbs and flowing descents, ensuring you'll always find the right gear, whether grinding up technical sections or maintaining momentum on varied trail surfaces.
The Tektro HD-M275 hydraulic disc brakes are fitted with large 203mm rotors and deliver consistent performance and reliable braking control throughout various conditions.
Built around Trek's proven Alpha Platinum Aluminium frame, the Powerfly+ 4 features guided internal routing and Motor Armour protection for enhanced durability. The tapered head tube and Boost axle standards ensure precise handling and accommodation for modern wheel and tyre combinations, whilst the practical design details make this bike as suitable for everyday adventures as it is for weekend trail exploration.
Bosch's eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
Perfect for riders seeking a capable e-MTB that excels on trails without breaking the bank, the Powerfly+ 4 800Wh offers the performance and reliability to expand your riding horizons with confidence and give you a ton of fun experiences.
