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 Powerfly FS 4 Gen 3 E-Mountain Bike in Blue Sage/Juniper

Season:2024

Brand:Trek

Code:40673BLU

The Powerfly FS 4 is a full-suspension electric mountain bike that's eager to hit the trail.

It packs in plush suspension to soak up rough-terrain and a powerful Bosch drive system to boost your capacity to crush long climbs and mile after mile of singletrack. It's equipped with Bosch's latest LED remote and Purion display that pair with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.

Features:

  • The Powerfly FS Gen 3 features Bosch’s smart system with an LED remote that connects to the Bosch eBike Flow app for over-the-air system updates, customised motor tuning and more
  • For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist smart system to its full potential
  • Trek's Removable Integrated Battery (RIB) system looks great and is really user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
  • The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  • It comes equipped with Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
