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

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

Powerfly+ 4 800 Wh Gen 5

Season:2026

Brand:Trek

Code:61707BLK

Powerfly+ 4 800 Wh is an adventure-ready electric mountain bike that doesn’t break the bank. Its rugged aluminium frame gives you a powerful boost thanks to a Bosch Performance Line CX motor with a massive 800 Wh battery. A bump-smoothing SR Suntour suspension fork boosts confidence on any trail while 10-speed Shimano CUES gives you clean shifting.

New RIB 2.0

Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or travelling, and you don’t have to worry about dropping it thanks to a secondary safety catch.

Extend your ride

Wanna take your ride even further? Pair a 250Wh PowerMore range extender with your bike to chase your most epic adventures.

Light, quiet, powerful: 100Nm upgrade ready

Bosch’s Performance Line CX motor has 85Nm of torque out of the box but can be tuned all the way up to 100Nm and 750W of power using the Bosch eBike Flow app, the all-new Bosch CX motor is lighter, quieter and now more powerful than ever without wavering on natural-feeling support for crushing epic rides.

Massive range for epic rides

Bosch’s new 800Wh battery gives you enormous range for chasing down your greatest adventures – or you can swap to a 600Wh option for a lighter-weight ride with more nimble handling.
