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

Trek Marlin+ 6 Electric Hardtail Mountain Bike 2025 in Crimson

Season:2025

The Marlin+ 6 is an electric mountain bike that's ready to power up your trail rides without breaking the bank. It's equipped with the same fun and confident geometry as the non-electric Marlin, with the added boost of Bosch's Active Line Plus drive system. A 120 mm suspension fork soaks up rocks, roots and potholes on your ride, while the 9-speed Shimano CUES is durable and reliable for wherever you roll.

You want a boost of power on the trail without spending an arm and a leg. You love the trail-to-town capability of the Marlin and want a ride that helps you ride a little faster or pedal further.

An Alpha Platinum Aluminium frame with real mountain bike geometry and a coil-sprung 120 mm fork. A reliable Bosch Active Line Plus 50 Nm drive system capable of assisting you to speeds of 20 mph/25 kph. A compact Purion 200 remote with built-in display. Plus, hydraulic disc brakes and a 9-speed Shimano CUES drivetrain that performs well, even under load.
