This awe-inspiring bike features an Alpha Platinum Aluminium frame with genuine mountain bike geometry and a responsive 120 mm air-sprung fork.

Controlling the bike is a breeze with the user-friendly Purion 200 remote, complete with a built-in display. A powerful 400 Wh Powertube battery ensures sustained performance, letting you travel greater distances with ease.
Whether you're new to electric mountain bikes or a seasoned rider, you'll appreciate the confidence the Marlin+ 8 gives you.

Plus, with numerous rack and mudguard mounts, you'll enjoy the flexibility of customising your bike to meet your everyday commuting needs or trail adventures.
Undoubtedly, where the Marlin+ 8 truly shines is its balance between power and subtlety. Its Bosch Active Line Plus mid-power motor delivers a potent 50 Nm of torque, yet its acceleration is controlled, its pedal resistance low and its operation whisper-quiet for a truly seamless ride.
Stay in control with its intuitive, compact handlebar controller that doubles up as a display. And rest assured that, with TREK's high safety standards, solid battery management fail-safe systems, and quality battery cells from tier 1 suppliers, you're always in safe hands.
Gear-up for grander ventures with the PowerMore add-on. This auxiliary battery extends your range, allowing for more supported ride time.

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.
