The 2025 Trek Marlin+ 8 Hardtail Electric Mountain Bike is ready to up your game on the trail. Its Bosch Active Line Plus motor gives you just the boost you need for getting up steep climbs and riding further, and doesn't break the bank, and a 120 mm suspension fork keeps handling smooth through the rough stuff.
The Marlin+ 8 is built around an Alpha Platinum Aluminium frame with real mountain bike geometry and a coil-sprung 120 mm fork. The smallest sizes come with a curved top tube and smaller 27.5 wheels to increase the stand over height. The larger bikes come with a straight top tube and 29" wheels for extra speed. The reliable Bosch Active Line Plus 50 Nm drive system is paired with a compact Purion 200 remote with built-in display and a 400wh battery.
On the Marlin+ 8 you get 12-speed Shimano Deore shifting, hydraulic disc brakes and wide, 2.6 in tubeless-ready wheels that boost grip and help prevent flats.
The Marlin+ is the go-to for riders looking to dip their toes into the electric mountain bike world. Its trail-savvy frame gives you confident control, and a Bosch Active Line Plus motor offers enough power to take the burn out of long climbs.
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 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 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 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.
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.
We understand that price is important, so we regularly price-check our competitors to make sure we have the best offers available. We recognise that we will not always be the cheapest, so if you see the same product cheaper from any of our competitors then please get in touch via the form below and we will do our best to match any reasonable advertised price.
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:
Build only products we love. Provide incredible hospitality to our customers, and change the world by getting more people on bikes.
