Arctic Leopard XE Pro S Review: Power, Range and App Tuning

The Arctic Leopard XE Pro S packs 20 kW of peak power, 600 N·m of torque and a 72V 55Ah battery into a bike that weighs about 159 lb. That combination has made it one of the most interesting mid-size electric dirt bikes of 2025 and 2026. This review explains what it does well, where it falls short and how to set it up so it rides at its best.

Arctic Leopard XE Pro S at a glance

What is the Arctic Leopard XE Pro S?

Arctic Leopard is a newer name in the electric dirt bike world, and its XE series targets riders who want more than a Light Bee class trail bike but do not want the weight of a full-size electric motocross bike. The XE Pro is the lighter, more agile model. The Arctic Leopard XE Pro S is the stronger version, with a bigger motor output, more torque and a more advanced controller.

What makes the Arctic Leopard XE Pro S stand out is its drivetrain. The motor feeds an integrated gearbox and a chain final drive, so there is no belt and no separate jackshaft. Fewer moving parts means less to adjust, replace and go wrong, which matters a lot on a bike that puts out 600 N·m at the wheel.

The other headline feature of the Arctic Leopard e bike is tuning. A Far Driver controller connects to an app over Bluetooth, so you can change throttle response, power and regenerative braking from your phone. Few bikes in this class offer that much control without aftermarket parts.

Arctic Leopard XE Pro S specs

Power, torque and acceleration

With 20 kW at peak, roughly 27 hp, the Arctic Leopard XE Pro S has around two and a half times the peak power of a stock Surron Light Bee X. The 600 N·m of torque arrives the moment you touch the throttle, so the bike pulls hard out of corners and up steep climbs without needing a clutch or gear changes.

That much torque in a 159 lb Arctic Leopard e bike takes respect. The front wheel lifts easily in the full-power map, and loose ground will spin the rear tire if you are heavy-handed. The good news is that the app lets you soften the power curve while you learn, then turn it back up as your skills improve.

Arctic Leopard XE Pro S top speed: how fast does it go?

Arctic Leopard quotes about 62 mph (100 km/h) in unrestricted mode. Real-world top speed depends on rider weight, gearing, tires and battery charge, and it drops slightly as the battery drains. For trail riding, the more useful number is how quickly it gets to 30 or 40 mph, and here the bike is very strong.

Gearing changes can trade a little top speed for even more acceleration, or the other way around. For tight woods riding, a slightly larger rear sprocket makes the bike feel even punchier. For open desert or fire roads, stock gearing is usually the best balance.

Arctic Leopard XE Pro S battery, range and charging

The Arctic Leopard XE Pro S battery is a 72V 55Ah pack that stores about 3,960 Wh, one of the larger packs in the mid-size class. Arctic Leopard quotes up to 100 miles at a steady 20 mph, but that is a best-case number. Around 50 miles of realistic trail riding is a better planning figure, and hard riding in the top power map will use energy faster.

Charging takes about 4 to 5 hours with the standard charger, so plan to charge overnight or between morning and evening rides. The battery is removable, which makes charging indoors easy and lets you carry a spare pack for long days.

To keep the pack healthy, store it at around 50% charge if the bike will sit for weeks, avoid leaving it in hot cars or freezing garages, and let it cool down after hard riding before you plug it in.

App tuning: the best settings to start with

The Far Driver controller is the feature owners talk about most. Through the app you can adjust throttle response, power output and regenerative braking. Here is how we suggest new owners set it up:

1. First rides: reduce peak power and choose a soft throttle curve. The bike is still quick, but much easier to control.
2. Trail riding: raise power gradually and add a moderate amount of regen, which helps on descents and saves brake pads.
3. Open terrain: unlock full power and a sharper throttle once you are comfortable with the bike’s weight and grip.
4. Wet or loose ground: step back down to a softer map. Less power often means more traction and faster progress.

Make one change at a time and test it, so you know what each setting does. Note down the settings you like, because it is easy to forget what you changed after a few rides.

Arctic Leopard e bike suspension, brakes and chassis

KKE suspension handles the bumps, with a 37 mm inverted fork offering about 200 mm of travel and a rear shock with 210 mm of travel. Both ends adjust, so you can tune preload and damping for your weight and riding. Setting sag correctly is the single best thing you can do for handling.

Braking comes from 220 mm hydraulic discs at both ends, backed up by adjustable regen. The 19 in front and 18 in rear wheels accept a wide range of motocross and trail tires, and the 830 mm seat height suits most adult riders. A TFT color display with NFC and passcode unlock adds a little extra security when the bike is parked.

Arctic Leopard XE Pro S vs XE Pro vs Surron Ultra Bee HP

Most riders comparing this bike are also looking at the standard XE Pro and the Surron Ultra Bee HP. Prices below come straight from our store:

The Arctic Leopard XE Pro is about 11 lb lighter and costs less, with the same battery and a similar top speed. It suits riders who value agility over outright torque. The 2026 Surron Ultra Bee HP has more peak power and a bigger battery, plus wheelie and traction control, but it weighs about 36 lb more.

Which Arctic Leopard should you buy?

Pick the Arctic Leopard XE Pro S if you are a stronger rider, ride a lot of hills, or want the most torque and the most tuning options. Pick the XE Pro if you ride tight trails, are lighter, or want to save some money without giving up range. Both share the same 72V 55Ah battery, chain drive and roughly 62 mph top speed.

You can compare both side by side in our Arctic Leopard range, or ask our team which one suits your riding.

Arctic Leopard XE Pro S pros and cons

Pros

• 20 kW of peak power and 600 N·m of torque in a 159 lb bike.
• Large 72V 55Ah removable battery with around 50 miles of real trail range.
• Chain drive with an integrated gearbox: no belt, no jackshaft.
• App-tunable Far Driver controller and adjustable regen.
• Fully adjustable KKE suspension and 220 mm hydraulic brakes.

Cons

• Strong torque can overwhelm new riders until the power is tuned down.
• Charging takes 4 to 5 hours with the standard charger.
• Smaller aftermarket and dealer network than Surron or Talaria.

Setting up your Arctic Leopard XE Pro S for the first ride

Start by checking tire pressure. Around 14 to 18 psi works for most trail riding. Then set rear sag with you on the bike in full gear, aiming for about a third of the rear travel. Adjust fork preload to match, and set rebound so the bike settles quickly after bumps without bouncing.

Position the levers so you can brake with one or two fingers while standing, and bed in the brakes with a series of firm stops. Check every bolt and spoke after the first couple of rides. Finally, open the app and set a softer power map for your first sessions.

Riding tips for a high-torque electric bike

• Keep your weight forward on climbs to stop the front wheel lifting.
• Roll the throttle on smoothly out of corners instead of snapping it open.
• Use regen as an extra brake on long descents.
• Stand on the pegs on rough ground and let your legs do the work.
• Watch your battery level and plan your route home with charge to spare.

Electric vs gas: what you save

A full charge of the Arctic Leopard XE Pro S battery (3,960 Wh) costs around a dollar at typical US electricity rates. There is no fuel, oil, air filter or top-end rebuild, and far fewer parts to wear out. Over a few seasons, the savings on fuel and servicing add up to a meaningful part of the purchase price.

Electric bikes are also quiet, which keeps neighbors and landowners happy and can open up riding spots where noise is a problem. Quiet riding also means you hear the trail, your tires and other riders more clearly.

Maintenance made simple

Routine care on the Arctic Leopard XE Pro S comes down to the chain, brakes, tires and suspension. Clean and lube the chain after muddy rides, check tension regularly, and watch brake pad wear. Bleed the brakes once a season and service the suspension when it starts to feel harsh. Do not point a pressure washer at the motor, controller, display or battery connectors.

Gear, transport and where to ride

Wear a DOT or ECE certified helmet, goggles, gloves, boots and body armor every time you ride. Budget $400 to $800 for good gear. To transport the Arctic Leopard e bike, a pickup with a ramp or a hitch carrier rated for at least 160 lb works well. Strap it down by the frame and bars, not the plastic.

The Arctic Leopard XE Pro S is sold for off-road use, so ride on private land, tracks and legal off-highway vehicle areas. Many state OHV programs welcome electric bikes. Always check local rules before you ride, and stay on marked trails. For more on the brand, see the official Arctic Leopard USA website.

Who should buy the Arctic Leopard XE Pro S?

The Arctic Leopard XE Pro S suits confident adult riders who have outgrown a 60V Light Bee class bike and want much more torque without jumping to a 190 lb full-size machine. It is a great match for hilly trail systems, riders who like to tune their bike, and anyone who wants a chain drive with fewer parts to maintain.

It is less ideal for true beginners, very light riders and anyone who mostly rides tight, slow singletrack, where the lighter XE Pro or a Light Bee class bike can feel easier. Heavier riders, on the other hand, benefit from the extra torque, because the bike keeps pulling hard on climbs with more weight on board.

A buying checklist before you order

• Confirm the battery size and that the charger is included.
• Ask whether freight to your door is included in the price.
• Check what the warranty covers and who handles claims.
• Ask which common parts, like brake pads, chains and tires, are in stock.
• Find out whether the bike is checked and set up before it ships.

Clear answers to these questions are a good sign that you are buying from a dealer who will still help you after the sale.

Upgrades worth considering

The bike is well equipped as standard, so most upgrades focus on comfort, protection and riding time rather than power:

• A spare battery for long days and weekend trips.
• Terrain-specific tires for mud, sand or hardpack. The 19/18 in wheel sizes give you plenty of choice.
• Hand guards and a skid plate to protect the controls and the underside.
• Springs matched to your weight if you are much lighter or heavier than average.
• A different rear sprocket to trade top speed for acceleration on tight trails.

Riding through the seasons

Lithium batteries deliver less power and range in the cold. Below about 40°F, expect the bike to feel a little softer and to lose some range, so store the battery indoors and fit it just before you ride. In summer, avoid leaving the bike in direct sun for hours and let the battery cool before charging.

Light rain and wet trails are fine, but avoid deep water crossings and never submerge the motor or battery. After a muddy ride, rinse the bike gently, dry the chain and re-lube it before storage.
