If you are cross-shopping a light electric dirt bike in Australia, it usually comes down to Sur-Ron, the brand that defined the category, and Arctic Leopard, the newer challenger built to undercut it. Both are throttle-only off-road electric motorbikes. Neither is road-legal here. The differences are in power, price and how much of a support network sits behind the bike.
Power and battery
Arctic Leopard leans hard into headline output. The XE Pro S runs a 72V 55Ah pack and around 20kW peak, and the flagship XE Pro R pushes to a 74V 60Ah pack and over 26kW peak. Sur-Ron's benchmark Light Bee X is a lighter, lower-output machine at around 8kW with a 2,400Wh battery, while the bigger Ultra Bee steps up to about 12.5kW and a 4,070Wh pack. On raw peak numbers Arctic Leopard reads bigger, but remember those are peak figures, not continuous output, and a lighter Sur-Ron can feel just as fast where it matters.
Weight and handling
The Sur-Ron Light Bee X built its reputation on being light and flickable, and that is still its strength. Arctic Leopard's XE Pro S is around 67kg and the Pro R about 79kg, so the bigger Arctic Leopards trade some agility for suspension travel and outright grunt. The compact Arctic Leopard XF, at around 58kg, is the closest in feel to the light-and-nimble Sur-Ron approach.
Price and support
Arctic Leopard's pitch is power-per-dollar: US retail starts around USD $5,799, and Australian supply is pre-order through a small number of off-road specialists. Sur-Ron is more established here, with a longer-standing dealer and parts network and settled Australian pricing (the Light Bee X from around $6,490, the Ultra Bee around $9,990, both varying by dealer). If you value being able to get parts and service locally, Sur-Ron has the head start; if you are chasing the most power for the money and are comfortable with a pre-order, Arctic Leopard makes the case.
The legal tie-breaker
Both brands are off-road only in Australia, so for most buyers the legal status is a wash. The one exception worth knowing: Sur-Ron offers a road-registrable version of the Ultra Bee that is built to meet the Australian Design Rules, which no Arctic Leopard matches. If riding on the road legally is even a distant goal, that pathway only exists on the Sur-Ron side.
