Take on the open road or conquer mountain trails with the TREK 2025 Powerfly+ 8 Gen 5, a top-tier hardtail electric mountain bike that's engineered for every adventurous ride. Its enduring alloy frame ensures durability whatever the terrain, from lofty alpine tracks to challenging city streets. The supercharged Bosch Performance Line CX motor assists on steep climbs, turning daunting ascents into exhilarating experiences.
The Powerfly+ 8 is equipped with high-impact components that all contribute to an unparalleled ride: Tubeless Ready wheels, an elevating dropper post, and a refined blend of Shimano SLX and XT drivetrain. This e-MTB is for riders who recognise the value of powerful acceleration, smooth uphill climb capability and the convenience a hardtail brings.
At the heart of this TREK bike is an Alpha Platinum Aluminium hardtail frame, combined with a resilient FOX Float AWL fork that features an air spring and RAIL 2.0 damper. The bike's sturdy construction is complimented by a Bosch Performance Line CX motor (85 Nm, 250 W), equipped with an 800 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. This bike also boasts a 12-speed Shimano SLX and XT blend drivetrain, Tubeless Ready Bontrager wheels, a Bontrager Line dropper post, and potent 4-piston Shimano hydraulic disc brakes.
The Powerfly+ 8 is much more than an electric hardtail; its practical enhancements make for effortless long distance treks and challenging trail manoeuvres. The Bosch Performance Line CX motor and large-capacity 800 Wh battery provide the supplementary power for those steep climbs, allowing for smoother rides over longer periods of time. It also has the added benefits of an upgraded fork, brakes, and drivetrain that will undoubtedly stand up to the rigours of any ride. - The powerfully versatile Powerfly+ is built to perform both off-road and on asphalt - Bosch's Performance Line CX motor delivers exceptional torque for challenging climbs, easily controlled via the Purion 200 remote. Personalise your ride with the eBike Flow app - Travel-friendly thanks to its RIB 2.0 removable integrated battery, conveniently portable for travel, and ensures a rattle-free ride - Compatible with Bosch's PowerMore booster batteries for those extra long ride sessions - Highly adaptable, featuring mounts for lights, mudguards, a rear rack, and kickstand
Take advantage of the Bosch eBike Flow app, allowing for a more personalised biking experience—adjust your motor's assist behaviour, record ride stats and integrate your data with apps such as Strava and Apple Health. It includes advanced features such as navigation and service reminders.

Our size guides are a helpful starting point, but they’re only a guide. For complete confidence, check the brand’s sizing advice or pop into one of our stores — because nothing beats sitting on your new bike to make sure it feels spot on.

The easiest way to determine your frame size is by height, but many riders find that they are between sizes. Choosing to go up or down a size depends on your personal riding style and body proportions.
A bike with a longer reach will have a longer wheelbase. That makes it more stable, especially on high-speed descents. That’s great for riders who like to plough through rather than pop over rough stuff on the trail. If you have a relatively long torso or arms for your height, you may find that a longer reach gives you a roomier, more comfortable cockpit.
A bike with a shorter reach will have a shorter wheelbase. It’s not as stable, but it’s more nimble and easier to flick around. That’s great for riders with a more playful, active riding style who like to get off the ground and whip their wheels around. If you have a relatively short torso or arms for your height, you may find that a shorter reach makes it easier for you to hold the handlebars comfortably.
Effective top tube
Effective top tube is the horizontal distance from the centre of the head tube to the centre of the seat post. This measurement represents how a mountain bike fits while you’re sitting on the saddle. It’s important for cross country riders, who prioritise pedalling power.
Reach
Reach is the horizontal distance from the centre of the head tube to a vertical line that runs through the centre of the bottom bracket shell. This measurement represents how a mountain bike fits when you’re standing up on the pedals, like when you’re descending. Since most trail riders prioritise out-of-the-saddle riding, this tends to be the most helpful metric when comparing bike sizes from different brands.

General Bike Size Guide
Choosing the right bike size makes a huge difference to comfort, control and efficiency. Use the guide below to find the ideal frame size for your height and inside leg measurement.
What You Need
Your Height
Stand with your back against a wall, shoes off, feet together. Mark the wall above your head with a pencil, then measure from the floor to the mark.
Your Inside Leg Length
Stand with your back against a wall, shoes off. Place a book or ruler between your legs (as if sitting on a saddle) and measure from the floor to the top of the book/ruler. Having someone assist makes this easier.
Remember: This guide provides general sizing only. Different brands may vary. If you’re unsure, speak to the Bike Shed team on 01363 774773 or send us a message — we’re always happy to help.
