See which exact factory part numbers appear across Sur-Ron models. Light Bee 2 is highlighted, and every shared part explains which other model catalog it came from.
Parts marked “also used on” were found under the identical factory part number in another model catalog.

Hyper Bee evolution · 2025 to 2026
The names can be confusing: sellers commonly describe the packs by cell count and rounded nominal voltage, while Sur-Ron's own tables use 48 V for 2025 and 58.08 V for 2026.
Depending on setup, rider and conditions, this version is often discussed as a roughly 35–37 mph bike. That is real-world shorthand, not the printed factory rating.
The 2026 bike is often described as a roughly 40–45 mph machine. The factory manual specifies 65 km/h; tire size, state of charge, rider weight and speedometer variation affect observed speed.
Hold the remote's MIC button to send your voice through the bike speaker. Triple-press MIC to turn on the bike/dashboard microphone and transmit audio back to the remote in real time. The bike microphone defaults off each time the motorcycle powers on.
Level 1 reduces power delivery and acceleration, but it does not provide a parent-selectable hard speed ceiling below 10 mph. A child can still build speed with enough distance. Treat Level 1 as a gentler throttle/power mode—not a walking-speed lockout.
The 2026 manual adds Sur-Ron Anti-Wheelie Control with four settings: W0 off plus W1, W2 and W3 intervention levels. It uses posture sensing to reduce unintended wheelies, but Sur-Ron explicitly says it is assistance—not an accident-prevention guarantee.
Factory references: 2025/V1 manual pages 16 and 51; MY26 manual pages 17–18 and 55; Hyper Bee Remote guide pages 9–10. The sub-10-mph limitation is EMR operating guidance, not a quoted factory claim.
Ultra Bee workshop triage
This is a first-pass field guide, not a substitute for the factory service procedure. Record the exact behavior, dashboard message, recent work, crash history, battery state, and conditions when the fault appeared.
Check for an active brake cutoff, deployed side stand, abnormal throttle input, ride-mode state, and a displayed fault code. Cycle power only after the controls return normally.
Confirm battery state of charge and seating, key position, main connector engagement, fuse condition, and visible harness damage. Do not repeatedly reconnect a hot or melted terminal.
Inspect pad and rotor wear, contamination, caliper alignment, lever damage, fluid leakage, and hydraulic pressure. A lever that reaches the bar or loses pressure means the bike stays parked.
Look for dry or tight chain links, damaged guards, loose axle hardware, spoke problems, bearing play, sprocket damage, and primary-drive failure. Find the source before applying more throttle.
Check fork alignment, preload and damping settings, linkage freedom, contamination, and seal condition. A light film and an active leak are different—drips or rapid oil accumulation need service.
Verify throttle clearance and return, battery latch preload, rubber supports, connector condition, and harness routing. Intermittent power under bumps often points to a mechanical connection problem first.
After a tip-over or crash
For an accurate parts inquiry, include the model year, fault code, clear photos of the installed part and connector faces, and the factory part number when visible. Similar-looking components are not proof of fitment.
Ultra Bee power guide
A controller can request more current than the original pack can deliver comfortably. Battery current, phase current, peak duration, temperature, state of charge, and model year all matter.
Treat 230 battery amps as a conservative short-duration ceiling discussed by Torp users—not a continuous factory rating. At nominal pack voltage that is roughly 17 kW before voltage sag.
Battery amps are drawn from the pack. Phase amps circulate between the controller and motor and can be much higher. An “800 phase amp” tune does not mean the battery is supplying 800 A.
A brief pull that works once may still overheat cells, busbars, connectors, the fuse, or BMS when repeated. Cold battery, low charge, and sustained climbing reduce the available margin.
Some advanced builders add resistance in parallel with the BMS current-measurement shunt. That makes the BMS report less current than the battery is truly delivering, which can delay its overcurrent cutoff. The linked community example reported the BMS seeing about 230 A while calculated actual current was roughly 373 A.
This does not increase the cells’ safe current capability. It intentionally makes current measurement inaccurate, can defeat the intended overcurrent margin, may create fire or shock hazards, and voids normal service assumptions.

Zoom with the controls or mouse wheel. Drag the diagram to pan. Double-click to reset.
The traction battery supplies P+ and P− to the motor controller. Three phase conductors feed the PMSM motor, with throttle, temperature, and position feedback returning to the controller.
The battery BMS shares the CAN network with the dashboard, controller, charger, GPS, and ABS where fitted. Communication compatibility matters when changing batteries or controllers.
The diagram separates the horn, lighting, switches, USB, dashboard, ABS, GPS, and wheel-speed signals from the high-current traction path.

Simple charge-only models
These fixed-rate models charge at one set current, like a factory charger. They are slower and simpler than the programmable model. The correct full-charge voltage and connector are selected for the battery before shipment.
Charge-only operation at a fixed 1.5 A rate. Best for overnight charging and lower-demand use.
Charge-only operation at a fixed 5 A rate. A familiar factory-style charging speed without programmable controls.
Input rating shown above is based on the supplied charger label. Safety-certification claims will be published only after the applicable certification file is verified.

Direct-fit performance motor for Sur-Ron Ultra Bee applications. Exact output and required supporting hardware will be verified for the customer's voltage and controller.
Compact geared motor for custom electric builds. Mount, reduction ratio, chain line, cooling, and encoder choice require project-specific review.

3Shul controller reference
Battery current and phase current are different. Never choose a controller from the headline current alone; voltage, cell capability, connectors, fuse, motor, cooling, and tuning must agree.
