Sur-Ron Light Bee X vs Ultra Bee HP
Same brand, same wheel sizes, same removable-battery idea — 34 kg and up to 14.5 kW between them.
The short answer
Consider the Light Bee X if you want the lightest and most forgiving bike in the range, if the rider is smaller or younger, or if the riding is tight, technical singletrack. It weighs 59 kg wet with an 830 mm seat, and it is the cheapest way into the brand at $7,490.
The Ultra Bee HP is the one to look at if you want to carry an adult on longer rides at higher speed, and to register the bike for the road. It makes 24.5 kW in Turbo mode, runs 240 mm of travel at each end, and is ADR compliant.
The gap is $3,000 before on-road costs, and 34 kg. Which of those two numbers matters more depends almost entirely on who is riding it and where.

What the extra $3,000 buys
Peak power goes from 10 kW to 24.5 kW in Turbo mode, and rear-wheel torque from 295 Nm to 520 Nm. The battery grows from 2.5 kWh to 4.44 kWh, and claimed range with it — 75 km at a steady 40 km/h becomes 115 km at 50 km/h on the WMTC cycle. Both packs come out of the frame for charging.
One caution on the Light Bee X figure. The current model is 10 kW and 295 Nm. A good deal of material still in circulation quotes 8 kW and 266 Nm, which is the previous model year. If you are comparing a dealer listing against this page, check which one the listing is describing before you draw a conclusion from it.
Weight is the real difference
59 kg against 93 kg is a 58 per cent increase, and you feel it everywhere that isn’t a straight line: from picking the bike up, turning it around on a narrow trail, lugging over a rock garden, to loading it into a ute.
The dimensions increase with the weight. Seat height goes from 830 mm to 910 mm, wheelbase from 1,255 mm to 1,380 mm, and suspension travel from 200 mm front and 210 mm rear to 240 mm at both ends. Ground clearance gains 48 mm.
Both bikes run the same 19in front and 18in rear wheels, so this is not a step from a small-wheeled bike to a full-size one. It is the same wheel package under a longer, heavier, taller and better-sprung chassis.
Fit, and who is riding
An 80 mm difference in seat height is the sort of thing that decides whether a rider can get a foot down confidently on uneven ground. At 830 mm the Light Bee X would arguably suit a shorter adult or an older teenager moving up; at 910 mm the Ultra Bee HP is sized for an adult. But like any bike, try before you buy.
The registration difference
The Ultra Bee HP is ADR compliant and can be registered. The Light Bee X is not homologated in Australia, so it is restricted to private property, gazetted areas and ride parks. Where you can legally ride an unregistered bike varies by state — our ride spot directory covers the rules state by state.
Sur-Ron sells the Ultra Bee HP in two road-legal versions at the same $10,490 price: the R on all-terrain tyres for mixed road and trail use, and the T on knobby off-road tyres. That choice is about where you ride, not about power or price — both make the same 24.5 kW and 520 Nm.

How we compared
- This is a specification comparison, not a ride test — in general we haven’t ridden the bikes and done direct seat-of-the-pants comparisons.
- For example, we can provide specifications on suspension or brakes where the information is available, but we can’t comment on how those components will perform for you and the various styles of riding you might undertake.
- We also cannot comment on long-term reliability and dealer support, which should be a factor in your purchasing.
- Figures are manufacturer claims as at the date shown, not independently measured.
- Prices are recommended retail unless a current sale price is shown, exclude on-road costs, and may vary by dealer and state.
- Registration and compliance are administered by each state and change — confirm with your state transport authority before buying.
We do our best to use up-to-date data, but even published data can at times be inaccurate or change, particularly with respect to pricing. Before purchasing always ensure you check the latest details and consider if the bike is right for you beyond the specifications.
