The Arctic Leopard XE PRO S wasn’t exactly on our radar—but after our first ride, we think it should be on yours. For a brand that’s had a relatively quiet presence in the U.S. lightweight electric scene, this new release hits a lot harder than we expected. With a claimed 20kW peak output, a class-leading 3960Wh battery, and a price tag around $5,399 (Current MSRP), it’s directly targeting bikes like the E Ride Pro SR and Ventus One Plus—but at a lower cost.
From the first glance, the XE PRO S looked more refined than other lightweight eMoto models we’ve tested. The chassis has a taller, more modern stance, and the full-size seat gives it a scale that is a bit more appropriate for adults. We immediately noticed the rear swingarm looked longer than most bikes in this class, so we measured it. Turns out, it’s about 1.75″ longer than the Ventus One Plus—a bike we’ve spent a lot of time on. That extra length explains why the rear felt so composed, especially under throttle.
Power Delivery and Tuning Potential
Power delivery is handled by a Fardriver controller, and while we haven’t always loved how these ride stock, this one felt surprisingly good out of the box. Throttle feel was clean, regen wasn’t overly aggressive, and we didn’t experience any surging or hesitation. Arctic Leopard includes full Bluetooth tuning via the Fardriver app, which opens up a lot of room to tailor power output, throttle curves, and regen braking. We didn’t dive deep into it for this ride, but knowing that headroom is there is a huge plus for performance-focused riders.
Key Upgrades: Bars, Tire, and More to Come
That said, there were two things that held the bike back in stock form: the front tire and the handlebar setup. The OEM front tire was undersized and lacked sidewall support, making the front end feel vague and harsh. We swapped it for a Dunlop MX34, which added both height and grip. The stock bars were also narrow and tall, which made the cockpit feel awkward. Swapping to a Warp 9 3-inch rise bar gave us better leverage and fixed the attack position. These are minor upgrades, but they dramatically changed how this bike felt.
We’d also likely upgrade to a drop crown triple clamp and a 21″ front wheel to give the bike more front-end height and better overall balance. That setup would help balance the bike out and bring it closer to the feel of a proper dirt bike – especially for off-road riders who are planning to ride primarily in the dirt.
On the Track: How Does the XE PRO S Ride?
With those changes made, we took the XE PRO S straight to the sand track. The stability we felt earlier on singletrack only became more evident as we started pushing the pace. The long swingarm helped keep the bike settled through acceleration chop and braking bumps, and the updated front end gave us the confidence to really push into corners. It’s not a race bike out of the box—but it’s in terms of the lightweight eMoto, it’s very competitive in stock form.
Suspension is handled by a KKE fork up front (approximately 200mm of travel) and a KKE rear shock. It’s not EXT-level performance, but it’s stiff enough to ride hard without blowing through the stroke. We didn’t bottom it, even on some harsh g-outs and jump landings.
The drivetrain appears to use a gearbox design, but without disassembling, the exact layout remains unclear. Arctic Leopard hasn’t released detailed technical specs on the gearbox, so we’ll avoid making assumptions. What we can confirm is this: it’s quiet, doesn’t use a belt, and the power delivery feels smooth and consistent. We’re always happy to see gearbox-based setups in these bikes, and this one performed well during our testing.
The TFT display is clean and legible, and Arctic Leopard includes both NFC and passcode unlock options. We appreciate the flexibility—especially since we never remember to carry NFC cards.
There are still some areas where we’d like to see improvements. The midsection plastic got scuffed up quickly from knee and boot contact, and the shape occasionally caught our boots while shifting weight in corners. A small design tweak here could make a big difference in rider comfort. And while we haven’t completed a full battery range test yet, we’re optimistic. Arctic Leopard batteries have consistently performed well in our range shootouts, and with 55Ah on tap, this one should go the distance.
So where does the XE PRO S sit in the growing field of sub-$6K electric dirt bikes? Right now, it’s one of the best values we’ve tested. It’s got the power to hang with the top-tier bikes, a stable chassis that encourages aggressive riding, and a battery that’s bigger than anything else in its price range. The few weaknesses it has are all fixable with relatively minor upgrades.
If you’re looking for a trail-capable, fast, and tunable electric dirt bike under $6K, this has quickly become one of the top bikes we’d point you toward.
XE PRO vs. XE PRO S: What’s the Difference?
It’s worth noting that Arctic Leopard also offers a standard version called the XE PRO. While nearly identical in frame and component spec, the XE PRO comes with a slightly smaller battery (72V 50Ah) and a lower peak power output (16kW) than the PRO S. For riders who want to save a little money or don’t need quite as much punch, the base model XE PRO still delivers a compelling package with the same core chassis and suspension setup, at a lower cost.
