There is a very specific hole in the current electric-dirt-bike market: riders who love the light, playful feel of an e-moto but want more stability, suspension and full-size wheels without jumping all the way back to a 250-pound motorcycle.
That is exactly where I have been shopping. After years on gas dirt bikes—including a KTM 500 EXC—and a lot of time on lighter e-motos, I want something that can handle real singletrack, jumps and roughly 30-mile rides while still being easy to load, move around and actually ride with my family. The Arctic Leopard XE Pro R and 2026 Sur-Ron Ultra Bee HP attack that problem from two slightly different directions.
I have real experience with the Sur-Ron/eRide side of this category. I have not yet put meaningful trail time on the Pro R, so I am not going to pretend this is a back-to-back ride test. This is an honest buying comparison based on my riding priorities, the manufacturers’ current specifications and what I would verify before spending my own money.
The short answer
On paper, the Arctic Leopard Pro R is the more aggressive value proposition: less weight, full-size 21/18 wheels, more claimed peak power and a lower starting price. The 2026 Ultra Bee HP gives up some of that spec-sheet advantage but brings a more established platform, a larger parts and owner community, and the kind of resale confidence that matters if you rotate bikes often.
| Specification | Arctic Leopard XE Pro R | 2026 Sur-Ron Ultra Bee HP |
|---|---|---|
| Claimed peak power | 26.5 kW | 24.5 kW in Turbo |
| Battery | 74V 60Ah / 4.44 kWh | 74V 60Ah |
| Claimed curb weight | 175 lb | 195 lb |
| Seat height | 34.3 in | 35.8 in |
| Wheel setup | 21/18 | 19/19 stock |
| Claimed top speed | 72 mph | 59 mph |
| Best fit | Lightweight full-size trail feel | Proven middleweight all-rounder |
Those are manufacturer claims, not an apples-to-apples independent test. Terrain, rider weight, tire choice, temperature and throttle use can change real range and performance dramatically.
Why the Pro R caught my attention
The Pro R’s numbers line up almost perfectly with the bike I have been describing to friends: around 175 pounds, real 21/18 wheels, more suspension and stability than a lightweight e-moto, and enough battery for a proper trail day. According to the official Arctic Leopard USA specification page, it uses a 74V 60Ah battery, a 26.5 kW direct-drive motor, 215 mm of adjustable front travel, 200 mm of rear travel and 240 mm four-piston brakes.
The weight is the headline for me. Twenty pounds does not sound enormous until you are correcting a bike in the air, muscling it through a rocky switchback or loading it after a long ride. The Pro R is still much more substantial than an eRide Pro-class bike, but 175 pounds keeps it closer to the “playful” side of the spectrum.
The 21/18 wheels matter just as much. They roll through holes and square edges more calmly, open up a huge range of real off-road tire choices and make the chassis feel familiar to anyone coming from a traditional dirt bike. For the type of mixed singletrack and faster desert terrain we ride, I would prefer that setup over buying a bike and immediately budgeting for a wheel conversion.
Where the Ultra Bee still makes the strongest case
The Ultra Bee already owns a useful middle ground. It is far more planted and motorcycle-like than a Light Bee or eRide Pro, yet it remains much lighter and simpler than most gas enduro bikes. The 2026 HP model raises peak power to 24.5 kW and keeps the 74V 60Ah battery. The current Sur-Ron Canada specifications list a 195-pound curb weight, 35.8-inch seat and 59 mph top speed.
The less exciting—but important—advantage is ecosystem. Sur-Ron has years of owner knowledge, replacement parts, setup advice and aftermarket support behind it. If I need a lever, brake part, wheel, controller solution or help diagnosing an odd behavior, there is a better chance somebody has already solved it. That is worth real money and downtime.
Resale is also easier to estimate. Many buyers know what an Ultra Bee is. Arctic Leopard is growing, but a newer brand and platform can require more explanation when it is time to sell. If you like to try a bike for a season and rotate the quiver, the Sur-Ron name may protect more of your exit value even if the initial performance-per-dollar is not quite as strong.
Power and range: ignore the biggest number
I would not choose between these bikes because one page says 72 mph and another says 59 mph. Neither needs more speed for technical family trail riding. Throttle calibration, low-speed control, traction, suspension balance and how the bike carries its weight will affect the ride more than the last 10 mph.
The same caution applies to range. Arctic Leopard estimates 50–60 miles, while Sur-Ron publishes a longer maximum range at a controlled speed. Those figures are useful for comparing battery capacity, but they are not promises for sand, climbing, soft tires and repeated full-power acceleration. A 74V 60Ah pack is substantial on either bike, yet I would still plan conservatively until I had logged my own route data.
For my use, the real question is whether the bike can finish a hard 25-to-30-mile trail ride with a comfortable reserve. I would test both bikes on the same loop, similar tire pressure and similar ride mode before making any range claim.
Which bike fits which rider?
Choose the Arctic Leopard Pro R if:
- You want the lightest full-size 21/18 package in this comparison.
- You value aggressive specifications and performance per dollar.
- You have a responsive dealer who can support parts, warranty and setup.
- You are comfortable adopting a newer platform.
- Your riding leans toward technical trail, jumps and full-size tire choices.
Choose the 2026 Ultra Bee HP if:
- You want a better-known platform with a mature owner community.
- Parts availability, resale and proven setup knowledge matter heavily.
- You prefer a slightly larger, more planted middleweight feel.
- You want a strong stock bike without being the early adopter.
- You expect to modify wheels, suspension or controls over time.

Before buying either one in California
These are not ordinary pedal e-bikes. California now classifies qualifying machines as off-highway electric motorcycles, and the California DMV says e-motos used on public OHV lands require OHV identification. Ask the seller for the manufacturer’s statement of origin, VIN information, a complete bill of sale and a clear answer about registration before money changes hands.
Also confirm local trail rules. A powerful e-moto belongs on legal motorized routes, private property with permission or designated OHV areas—not on mountain-bike-only singletrack or public streets simply because it is quiet.
My current verdict
The Arctic Leopard Pro R is the more interesting bike on paper for the way I ride. The 175-pound claimed weight, 21/18 wheels and 4.44 kWh battery hit the sweet spot I keep looking for: more capable than a lightweight e-moto without recreating the bulk of a gas motorcycle.
But the Ultra Bee is the safer ownership decision. It has the established platform, community and resale story. If I were ordering blind from an unknown seller, I would lean Ultra Bee. If I had a strong local Arctic Leopard dealer, parts access and a chance to ride the Pro R first, the Pro R might be the one that earns the space in the garage.
That is the real answer: do not buy the winner of a spreadsheet. Buy the bike whose weight, dealer support and trail manners match how you actually ride.
