If you’ve been wanting to get your off-road e-biking thrills but think all the current eMTBs on the market are too weak with their paltry 750W motors, then Biktrix has just what you’re looking for. The new Biktrix Juggernaut FS XD is the full-suspension electric mountain bike equivalent of the hot-rodder’s hot rod.
Over 2,000 watts of power in an electric mountain bike is no joke, and Canadian electric bike maker Biktrix had to go back to the drawing board to make it happen.
The new e-bike required a custom-built mid-drive motor that was designed in-house by the Biktrix team. Instead of a massive and clunky rear wheel motor to get there, the mid-drive motor built by the company keeps the bike more balanced and allows riders to preserve the type of handling expected from a mountain bike.
And as you can imagine, having nearly 10x the amount of power produced by a human could wreak havoc on traditional bike parts like chains and sprockets, so Biktrix had to get custom there, too. The company designed a second drivetrain just for the motor power, feeding the rear wheel through a higher spec chain and sprocket set on the left side of the bike.
As the company explained:
“The innovative Coaxial-Drive motor provides all the handling and weight distribution benefits that come with a mid-drive motor. But with all this power you need a drivetrain to handle it! The Juggernaut XD features a motor side drivetrain designed specifically to handle the power this motor puts out to keep this bike even more reliable than your average mid-drive motor.”
Of course a big motor means that you’d better have a big battery as well, otherwise that fun ride is going to get cut short. Supplying the Juggernaut FS XD’s motor is a 52V 17Ah battery with 910 Wh of capacity.
The company reports an estimated range of 40 miles (64 km) from the battery, though full-power riding that makes full use of the 2,300W motor is sure to drop that range.
The range estimate likely comes from using pedal assist, though there’s a throttle too for peak fun. Riders who can resist relying purely on the throttle will find that the torque sensor pedal assist is designed to be as intuitive and responsive as possible, feeling more like a true mountain bike when you pedal it than a light dirt bike.
And it’s no surprise that a bike built with this much power also comes with heavy-duty components. The wheels feature 15mm and 12mm thru axle hubs in the front and rear, respectively. The brakes use dual-piston hydraulic calipers with 180mm and 220mm rotors. The transmission is a SRAM NX 11-speed. And the tire sizes come in three larger-than-life options of 26×4″, 27.5×3″, 26×4.8″.
To top it all off, the suspension features a Rockshox Monarch Rl rear shock with 51 mm of travel as well as five different fork options depending on how serious you want to get with your riding. The fork options include:
- Biktrix Inverted Air Fork with 100mm travel
- Manitou Mastadon Comp with 100mm travel
- Wren Inverted Air Fork with 110 mm travel
- Wren Inverted Air Fork with 150 mm travel
- Wren Inverted Air Fork with 110 mm travel, lockout and preload
Considering the bike’s weight is listed at 71.9 lb (32.6 kg) before the battery is inserted, those suspension options (and likely the powerful hydraulic disc brakes) are going to be well-appreciated components indeed.
The Biktrix Juggernaut FS XD carries an MSRP of US $5,999, but there are some serious savings to be had. The bike is rolling out with a $1,000 off sale as part of the launch, and anyone who puts down a $100 pre-order deposit gets another $500 discount on top of that.
For an all-in price of $4,499, the picture is looking pretty darn rosy for such a powerful and high-spec e-bike. Just remember that with this much power comes some serious responsibility, which includes riding only where permitted and being courteous to other trail users.
Electrek’s Take
Alright, so this bike is pretty ridiculous, but in all the best ways. I mentioned the issue of being courteous of other trail users, but with this much power and suspension, you can leave the trails behind and chart your own overlanding course.
I’ve had a lot of experience with different Biktrix e-bike models over the years and have always been impressed with the company. They take pride in building e-bikes that aren’t just cookie-cutter white-labeled models chosen from an OEM’s catalog.
That means they cost a bit more, but you’re paying for the innovation. That motor certainly wasn’t cheap to develop, nor was the dual drivetrain.
Some people will probably say “just get a Sur Ron or dirt bike for that price”, but I’d argue they’re missing the point. This is still an electric mountain bike, and it still rides like one – albeit a bit heavier than most riders will be accustomed to. Just because it has 2,300W of power doesn’t mean you always need to ride it in full power mode. You can crank the power up to climb a mountain, then drop it back down to get a nice workout on the trails at the top. Most minivans can get up to 100 mph, but they rarely do. People like knowing they have the performance, even if they keep it to much lower levels most of the time. I see the Biktrix Juggernaut FS XD through a similar lens. It has the power and performance to take you places other e-bikes couldn’t, but you can always drop the power back down and ride it like an eMTB. That’s just not possible with a dirt bike or Sur Ron.
