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

Trek Powerfly 4 625w Gen 4 Electric Mountain Bike 2023 in Living Coral and Grey

Season:2023

Brand:Trek

Code:37042LivingWHTSolidCHA

The Powerfly 4 625 takes Trek's most affordable electric mountain bike and gives it a boost with a longer-range 625 watt-hour battery. Of course, you still get their user-friendly Removable Integrated Battery (RIB) system that's super easy to remove and reinstall, plus all the other parts that make Powerfly 4 your ideal entry into the joys of riding a pedal-assist bike on or off-road.

You're sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn't resemble the car you're trying to use less. You want bigger, better off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.

A tough yet refined aluminium frame that fully encases a long-range 625 Wh battery for sleek looks, a Bosch Performance Line CX (250 W, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe), a Bosch Intuvia smart system controller, a 1x10 Shimano drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

This model gives you a longer-range battery than the standard Powerfly 4, so you’ll never be short on fun.

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