Explore further, rip harder. Trek electric mountain bikes let you conquer climbs and crush laps with natural-feeling boost that makes light work of sky-high trails that point straight up, so you can get to the top without feeling winded for the down. Our e-MTBs give you the same trail-taming tech as our traditional mountain bikes because they are built on the same legacy of frame and suspension tech that’s been trail-tested and trusted for decades.
Ride it, rally it and power back to the top for more.
What is an electric mountain bike?
e-Mountain bikes are trail-savvy bikes with an electric assist system that boosts your own power. They help you cruise up steep climbs with ease and conquer longer days in the saddle. Like a traditional mountain bike, e-MTBs are built with rock-gobbling suspension and rugged frames that can handle rocks and roots, so you can count on them to keep rolling through the rough.
How do electric mountain bikes work?
Trek e-MTBs use a pedal-assist motor. Pedal-assist systems provide power that helps keep your wheels spinning when you pedal and switches off support when you stop pedalling for a natural-feeling ride and control weaving through tight, technical singletrack.
What kind of motors do e-MTBs use?
All Trek electric mountain bikes are built with mid-drive motors that are located at the centre of your bike, near the front chain ring. Mid-drive motors provide a stable centre of gravity and are available with a huge range of power capacities to give you the right amount of support for how you want to ride.
Safer, sustainable batteries
All Trek e-bike batteries are third-party certified for safety and durability, so all you need to worry about is where you’ll ride next. Plus, we've even partnered with Call2Recycle to safely recycle used e-bike batteries at the end of their life to keep them out of landfills.
Why you’ll love your e-mountain bike
Electric mountain bikes give your personal pedal power a boost, so the only thing taking your breath away is the view at the top of the climb. They empower you to ride further, ride faster, soar up steep trails and tackle more grin-inducing miles with friends.
Better design for a better ride
The best ride quality starts with an e-bike motor made by brands you can trust. We exclusively partner with the top e-bike drive system manufacturers, so you get technology you can count on for thousands of rough and rowdy miles to come.
Bringing over a century of experience to the table, Bosch offers the most trusted e-bike technology you can take to the trail. With powerful, natural-feeling motors that offer up to 100 Nm of torque and 750 watts of power, and a smart eMTB assist mode that adjusts power seamlessly based off the torque you’re putting into the pedals and the terrain you’re riding, Bosch is a tech leader that knows you want to focus on the miles ahead – not your motor.
TQ hit the trail in 2022 with the lightweight HPR-50 drive system that flipped the industry on its head – and it has only got better from there. The latest TQ motor now features 60 nm of torque and 350 watts of power, and is so compact and quiet you might forget it is even there.
The best electric bike components in the world are only as good as the brands that back them up. No matter where you are on the globe, you’ll find support from TQ, Bosch and of course, your friends here at Trek.

Electric mountain bike FAQ
Q: How do I choose an e-mountain bike?
A:We offer a variety of electric mountain bike models that are both hardtail and full suspension. It really depends on the terrain you'll be riding and how much range, torque and battery power you need. If you still have questions, we're here to help. Get in touch with us or stop by your local Trek retailer and we'd be happy to help you find the perfect e-mountain bike for your needs. Or, if you want to find one now, try our E-bike Finder.
Q: Why would I choose an e-mountain bike over a regular mountain bike?
A:Unlike a traditional mountain bike, e-MTBs can provide you with an extra boost to tackle longer trail rides, steeper climbs and keep up with your ride group. With models like the Marlin+, you can even add a rack to turn it into an electric commuter bike. While the trade off is weight in most cases with an e-mountain bike, newer e-systems like TQ, minimise this difference.
Q: What should I look for in an electric mountain bike?
A:First, you always want to make sure your e-MTB is UL-compliant so it can be safely charged and stored. All Trek and Electra e-bikes are compliant to the UL2849 standard. Next, you'll want to look for a quality e-system from a reputable manufacturer like Bosch, Hyena or TQ. Those companies provide long-term service and support for their products so your investment can last. Finally, you want to look for quality components like front and rear shocks, drivetrains, brakes and wheels designed to withstand the force and weight of an e-mountain bike. Trek prides itself on making some of the best (award-winning) e-bikes on the market.
Q: Should I buy an electric hardtail mountain bike or a full-suspension electric mountain bike?
A:The travel, location on the frame and type of suspension you need really comes down to two things:
1. Where you ride! For example, if you’re riding a downhill course, you'd want a full-suspension e-mountain bike with enough travel to soak up bumps while keeping you connected to the trail.
2. Personal preference. Some riders may prefer the lightweight feel and simplicity of a hardtail compared to the extra suspension and traction offered by a full-suspension eMTB. We recommend popping into your local Trek retailer and talking to our mountain bike experts who can help you find the perfect electric mountain bike for your riding style.
Q: What is the average range of an electric mountain bike?
A:Depending on battery capacity, riding speed and terrain, range can vary anywhere from two to five hours on a single charge. Some eMTB models have Range Extenders to provide more range if you’re looking to ride longer between charges.
