Need to upgrade your mountain trail e-bike in 2026? Exhausted by countless advertisements, sponsored posts, and half-truths? You’ve come to the right place to assuage those concerns.
We’ve scoured the internet to find the most popular mountain e-bikes and trail e-bikes of the last year. We will analyse what makes each of them special and how they compare to one another.
Once that’s done, we’ll give you our pick for the best heavy-duty mountain trail e-bike.
How are we judging these bikes?
High torque motors are super important in the realm of mountain and trail biking. You don’t want to be left stalled on an uphill climb, having to push the behemoth that most modern electric mountain bikes are. We expect a minimum wattage of 600W; anything higher is a bonus. This is because we want to see at least 85 Nm of torque in our for a mountain bike. As a bonus, we’d love to see torque sensors in the bike so it can sense exactly how much pressure you’re applying to the pedal and deliver power accordingly, rather than delivering it every time you pedal.
Excellent suspension depth; tuning is a bonus, but we understand it is often a premium service that occurs after purchase. But we expect at least 12-14 cm of suspension travel to allow you to ride your next mountain e-bike on the trickiest terrain. Similarly, we expect a top-notch gear system, preferably branded, with at least 10, preferably 12, speeds to work in cadence with the suspension system.
High-capacity batteries are a must. You don’t want to get stranded in the middle of nowhere. We’ll assume you have to ride to and from your trail expedition, so we’ve set a minimum capacity of 600 Wh. While talking about batteries, we also need to stress the importance of an IP waterproof rating and a UL safety rating, both of which are especially important given the conditions under which you’ll be using these bikes.
Thick, robust, and puncture-proof tyres. If city-commuter e-bikes can boast puncture-proof tyres, so should mountain bikes. We also expect a minimum tyre thickness of 2.5 inches, with thick grooves, of course.
With the rules of the game set, let’s get down to business. The most commonly found mountain e-bike across the lists we analysed was a tie between the Aventon Ramblas and the Mokwheel Onyx. The Ride1Up TrailRush closely followed them.
Let’s analyse what makes each of them popular, one at a time.
Starting with the Aventon Ramblas.
Priced at $2899, Aventon’s 2024 release was recently succeeded by the Current ADV and EXP models. But let’s start by analysing what made the Ramblas so popular in the last year.
The Ramblas is powered by an Aventon A100 mid-drive motor, which can deliver up to 250 W continuously and peak at 750 W, producing 100 Nm of torque, well above our stipulated benchmark. Depending on your stature, the Ramblas is available in medium, large, and extra-large, so pick your bike accordingly.
The Ramblas comes with Aventon’s own battery, which stores up to 700 Wh of energy to power the e-bike, well above our 600 Wh benchmark. It also features a torque motor that adapts to the intensity of your pedalling rather than its cadence, giving you a smoother, more responsive ride. This translates roughly to a 90-mile range on a conservative battery setting.
The bike also features a 12-speed SRAM gear system, yet another check in the box for Aventon. However, it has only front suspension rather than dual suspension, and the single-suspension fork features 130 mm of travel, which is more than sufficient. While the suspension is a definite markdown, the Ramblas is quickly redeemed by the dual hydraulic braking system, which is far smoother than disc brakes, which are older technology that risks throwing you overboard at the first instance of sudden braking, a common occurrence on some trails.
The 29-inch wheels also feature 2.4-inch tubeless tyres out of the box, which is a definite check in our stable tyres section. All things considered, we will score this one 3.5 out of 4, making it a definite contender for our overall pick here.
Up next is the Mokwheel Onyx, which tied with the Aventon Ramblas for mentions across various sources and lists.
The Onyx is Mokwheel’s flagship offering in the mountain e-bike space. For $3200, the Onyx is available in either a step-through or a crossover frame.
The Onyx is equipped with a TruckRun motor that can regularly deliver 750-1000 W and sustain up to 1300 W, depending on usage. This motor’s performance delivers a whopping 210 Nm of torque, meeting our requirements for benchmark torque and motor power.
The Onyx tops out at 20 mph on the throttle and can boost you to 28 mph when using pedal assist. Of course, this is subject to local restrictions, which limit speeds to 15 mph in certain regions. At 89 lbs (41 kg), this hefty bike is more than stable and solid to handle the tricky trails and the harsh ups and downs they bring. The bike’s frame can support up to 560 lbs (250 kg), which is a welcome feature.
The Onyx’s dual suspension, which travels up to 13.5 cms, is a definite checkmark, and the dual-hydraulic brakes are a huge bonus, like with the Ramblas. Similarly, the Onyx comes equipped with a 10-speed Shimano system that works in lockstep with both torque and cadence sensors to deliver the most responsive ride possible. All those features, when combined with the 26-inch-wide wheels and 4-inch-thick puncture-resistant tyres it comes with out of the box, make the Onyx a formidable case against the Ramblas.
The Onyx’s most prominent shortcoming is the range. Equipped with a 48V 19.6A battery that complies with UL standards and is IPX7 rated for waterproofing, it fails to deliver the mileage the Ramblas can. At a range of between 60 and 80 miles, the Onyx under-delivers by almost 10 miles when pitted against the Ramblas. All in all, much like the Ramblas, we rate this bike a 3.5 out of 4.
Finally, the proverbial bronze medallist in the mountain e-bike space is the Ride1Up TrailRush, which was the second-most-often mentioned mountain e-bike after the Ramblas and Onyx.
Ride1Up’s TreailRush will set you back $1995, making it the most affordable eMTB that was still a common sight across the various lists we analysed.
The TrailRush is fitted with a Brose TF Sprinter mid-drive that can easily generate 90 Nm of torque, which immediately checks our box for power delivery, without the cost of a flagship Bosch motor. Similar to the two options before this, the TrailRush comes with front and rear Tektro hydraulic brakes, but it only features front suspension that can travel up toup to 12 cm.
While the TrailRush lacks in the suspension department, it is sufficient in the gear department, featuring a 10-speed Shimano system. Further, the TrailRush comes equipped with a 36V 14Ah battery. However, it has a range of between 30 and 50 miles, which leaves a lot to be desired.
Like the two former contenders, this bike also comes equipped with 29-inch tubeless tyres measuring 2.4 inches wide. This is also sufficient for lighter trails that are easier on the frame and wheels, but not necessarily the heavy-duty use that one might expect from a flagship mountain bike.
Users have raised several concerns about the TrailRush. Most commonly, the powerful motor comes with a battery that leaves much to be desired. Some other users have complained that the lack of any official waterproof rating, while cost-saving, has left the bike susceptible to water damage, which a few users have experienced.
All things considered, we’re docking points for single suspension, poor range, and the lack of IP (or equivalent) waterproofing. This leaves the TrailRush rated 2.5 out of 4, making it our lowest-rated mountain e-bike here.
Having analysed all the options that several publications and databases have weighed in on, we think the best mountain e-bike has to be either the Aventon Current ADV or EXP models.
If you’re looking for a budget trail bike that was released this year, go with the Aventon Current ADV. Are the purse strings not a problem? Then the Current EXP is the way to go.
The commonalities first. Both the ADV and the EXP weigh around 50 lbs (22 kg). They both feature Aventon’s flagship Ultro X motor, which delivers 110-120 Nm of torque, clearing our bar. They both have an 800 Wh integrated battery, which is also a giant bonus. The range on both these machines is roughly 105 miles, which clears our benchmark.
Further, they both feature a 12-speed SRAM drivetrain, dual suspension, and hydraulic brakes.
The differences now. Firstly, the pricing. The ADV will set you back $3999, while the EXP costs $5999. For its modest cost when compared to the EXP, the ADV features an entirely aluminium frame, while the EXP features a combination of Aluminium and Carbon steel. The EXP also boasts a better SRAM gear system and upgraded fork and shock. However, both the ADV and the EXP share a 44 mm suspension travel.
Beyond these, both bikes also feature seamless tech integration and list your devices on Apple and Google’s “Find My” services. They also feature 3 power modes: pedal assist, boost, and auto. Finally, and most importantly, both bikes feature 29-inch tubeless, puncture-proof, 2.5-inch fat, grooved tyres, which leave you ready to hit any trail you want.
