Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

2026 Trek Marlin 5 Mountain Bike in Fury red

Season:2026

Brand:Trek

Code:57363RED

Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. It features a trail-savvy frame with a suspension fork, 9-speed Shimano cues shifting and mounts for a rack and kickstand that make it an ideal choice for trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.

Will my bike have a curved top tube?
Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.

Fit for every rider
Marlin comes in seven frame sizes to suit riders of any height, and smart wheel size ensures youâre on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value
Marlin looks and feels great. Itâs packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Shimano cues
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano cues offers a new foundation for versatility and durability across a range of both electric and standard bikes. Cues features shimanoâs new linkglide drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.
Shimano linkglide
linkglide technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting â along with a great pedalling experience. Available exclusively on Shimano cues drivetrains.Upgrade your pedals and love your bike morepedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride.
