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 our 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.

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.

- The better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you're pedalling, and has less drag when you're not

- 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

- The Shimano drivetrain gives you a lot of gears and a wider gear range, so you can always find the right cadence for getting the most out of the motor

- 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

Electric Bike Updates and Diagnostics

As electric bikes have become more sophisticated it’s important to stay on top of updates. Just like your home computer or smart phone regular updates are now released for most electric bike systems. If you buy a bike from Cycles UK we will do electric bike updates and diagnostics you need free of charge.

Electric Bike Updates

Electric bike updates can help to improve battery life, tweak how the motor works and fix bugs and problems. Most systems will require you to plug your bike into some specialist software at an authorised dealer. At Cycles UK we are authorised dealers for top electric bike brands including Specialized, Trek, Orbea, Whyte, Cannondale and Raleigh. As a result our stores have the software and hardware to run updates on all the major electric bike systems including Bosch, Shimano and Ebikemotion.

We now provide free updates and diagnostics for life on any electric bike purchased from Cycles UK.

Electric Bike Motors Explained

Electric bikes have really come into their own in the last couple of years. Thanks to advances in electric bike motors and batteries. A couple of bike manufacturers, most notably Specialized, are making their own electric bike motors. The vast majority of bike companies are using the same motors. So, you will find exactly the same electric motor being used on bikes from different brands and at different price points. In this guide, we’ll take you through the main types of electric bike motors. Look at the differences between the most commonly used brands.

Electric Bike Hub Motors vs Mid-Drive Motors

Electric bikes tend to either come with a hub motor or a mid-drive motor. Mid-drive motors sit where the cranks and bottom bracket are on a bike and drive the cranks and chain around. Hub drive motors sit in the middle of the wheel and drive the wheel directly. Hub drive electric bikes are cheaper but less efficient, and less smooth, to ride.

Trek Electric Bike Range Guide

The Trek electric bike range has been pretty enormous at times. This has mainly been due to a single model of bike being available in multiple battery and colour variations so you quickly ended up with dozens of variants. Thankfully Trek have scaled this back a little recently, and their electric bike range is now easier to understand.

Until recently nearly all Trek electric bikes came with Bosch motors. For the 2023 season they are continuing with Bosch but also introducing motors from new brands like TQ and Hydrive on selected models.

Trek made their first bikes in 1976 in a barn in Wisconsin. Now they’re one of the biggest bike brands in the world. Trek bikes cover everything from professional-level road and mountain bike race bikes to commuters, hybrids and kids bikes. There is a strong heritage of racing at Trek and many Trek bikes have a strong race influence. They take a very scientific approach to researching bike and human performance and then make the fastest and most efficient bikes they can.

It doesn’t stop their attention and passion for cycling flows through everything they do. Since the 1990s, Trek has supported Places for Bikes. Places for Bikes is an advocacy organisation in the USA that gets more people on bikes more often! Places for Bikes ethos falls in line with the companies mission statement to:
