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!


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.

Trek Powerfly 5 Gen 4 Electric Mountain Bike 2024 in Prismatic Black




The Powerfly 5 is a highly capable electric mountain bike that balances performance and price. It pairs a high-end Bosch e-MTB drive system with durable mountain bike components built to stand up to the trail. Plus, it features Trek's user-friendly Removable Integrated Battery (RIB) system that fully encases the battery in the frame, yet doesn't require tools for removal. This bike is versatile, capable and ready for adventure.

You've seen the e-bike light and want to expand your boundaries. Like Trek, you believe that nothing should stand between you and your next great ride, including big climbs, headwinds and rugged trails that you wouldn't otherwise be able to explore.

A lightweight and durable aluminium frame that fully encases a 625 Wh battery for sleek looks and protection on the trail, a Bosch Performance CX motor that assists up to 20 mph (25 km/h in Europe) and an ergonomic Bosch Intuvia smart system controller. A RockShox Recon Silver RL fork, a Shimano 1x12 drivetrain and Bontrager Kovee Comp 23 tubeless-ready wheels.

With Powerfly 5, you get parts upgrades that make a big difference riding off-road, like an air-spring fork that's smooth and adjustable for your own weight, plus more powerful 4-piston brakes and wheels that make it easy to ditch the tubes for better traction and flat protection.

Please note: the XS and Small sizes have a curved top tube to help with standover height.
