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 Bike Pearl Grey Lithium X-Small

Season:2024

Brand:Trek

Code:PFLY4PGLG

The Powerfly 4 625 takes our most affordable electric mountain bike and gives it a boost with a longer-range 625 watt-hour battery.

Of course, you still get our user-friendly Removable Integrated Battery (RIB) system that's simple to remove and install, plus all the other parts that make Powerfly 4 an ideal entry into the joys of riding a pedal-assist bike on- or off-road.

It's right for you if - 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.

The tech you get - 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 display with LED remote, a 1x9 Shimano CUES drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means that riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

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

Features:

  • The Powerfly Gen 4 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
  • Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
  • The Intuvia controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
  • It's equipped with an external charging port for easy charging on or off the bike
  • You can boost your Powerfly’s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor
  • You can boost your Powerfly’s utility by adding a rack and fenders, plus built-in wiring lets you easily install lights powered by the motor
