The lightweight electric dirt bike category is entering a new phase. Early models proved that a compact electric platform could combine mountain-bike-like agility with motorcycle-style power. The latest generation is moving beyond that formula by integrating higher-output powertrains, denser batteries, stronger chassis structures and more sophisticated electronic control.
The Light Bee 2 is one of the clearest signs of that shift.
Regional Surron product information presents the Light Bee 2 as a 65 kg electric off-road motorcycle with 24 kW of peak power, a 78.54 V 45 Ah battery rated at 3.53 kWh and a claimed maximum speed of 90 km/h. It also introduces the EVO-2 powertrain, an integrated reduction gearbox, a semi-solid-state battery and a new control architecture. These specifications are based on the currently published regional product page and may vary by market or final homologation.

The importance of the Light Bee 2 is not limited to one model. It shows where the broader electric off-road market is heading.
1. Lightweight Platforms Are Moving Into a Higher Power Class
The original Light Bee helped define the lightweight electric dirt bike category. Its appeal came from manageable weight, compact dimensions and accessible off-road performance.
The current 2026 Light Bee X regional specification continues that formula with 10 kW maximum power, a 72 V 35 Ah battery and a 59 kg curb weight. The Light Bee 2 moves the platform concept into a substantially higher output range while keeping its published curb weight at 65 kg.

This change matters because it reduces the gap between lightweight electric trail bikes and larger electric off-road motorcycles. Customers are no longer choosing only between a light, modest-output machine and a heavier high-power motorcycle. A new middle and upper-middle category is taking shape.
For manufacturers and suppliers, this creates demand for motors, batteries, controllers and chassis components that can deliver higher output without making the complete vehicle unnecessarily complex or difficult to control.
2. Peak Power Is Becoming More Important—and More Complicated
The Light Bee 2 product page promotes a 24 kW peak output and also notes that a 35 kW peak was recorded during controlled Surron R&D testing. Those figures describe different operating conditions and should not be treated as interchangeable.
This illustrates a wider industry issue: the phrase “peak power” does not always use one universal test method.
When evaluating an electric dirt bike, buyers should ask:
- Is the number rated power, sustained peak power or instantaneous peak power?
- How long can the system maintain that output?
- What battery state of charge and temperature were used?
- Is the limitation set by the motor, controller, battery, BMS or thermal strategy?
- Is the figure measured electrically, mechanically at the motor shaft or at the wheel?
The same discipline applies to the TRB Apex. Its confirmed specification identifies 26 kW as rated motor power and 52 kW as instantaneous peak motor power. That wording is intentional: it prevents a short-duration maximum from being presented as continuous output.
For a detailed explanation, read: 24 kW, 35 kW or 52 kW? How to Read Electric Dirt Bike Power Claims.
3. Powertrain Integration Is Replacing Component-Level Thinking
The next generation of electric dirt bikes will not be defined by the motor alone.
The Light Bee 2 highlights an integrated EVO-2 powertrain with a compact motor, reduction gearbox, controller architecture and battery designed around the same platform. This reflects a broader engineering direction: optimize the complete energy and drive path instead of selecting isolated high-number components.
A high-output electric off-road system must coordinate:
- Battery voltage, capacity and discharge capability.
- BMS current limits and protection settings.
- Controller input current and phase-current limits.
- Motor torque, speed and thermal characteristics.
- Reduction ratio and final-drive gearing.
- Cable, connector and contactor capacity.
- Cooling, fault protection and software calibration.
If one element is mismatched, the headline power figure may not translate into repeatable real-world performance.
This is also the philosophy behind the TRB Apex 52 kW performance system. Its 72 V 45 Ah battery, E100 Pro FOC controller and mid-mounted motor are presented as one system rather than unrelated specifications.
4. Battery Development Is Becoming a Competitive Differentiator
Motor output attracts attention, but the battery determines how much electrical energy and current the system can supply.
The Light Bee 2 regional page lists a 78.54 V 45 Ah semi-solid-state battery with 3.53 kWh of energy. It also emphasizes pack weight, discharge capability, cycle life and cold-weather performance. Whether every claimed characteristic is available in every market should be verified with the relevant regional distributor, but the direction is clear: battery technology is becoming a central product story rather than a hidden component.
The TRB Apex uses a different confirmed configuration: 72 V 45 Ah with 3.24 kWh of nominal energy. Its user-confirmed battery specification includes a 15C discharge rate, 300 A RMS current and 600 A peak current.
Voltage and amp-hour capacity alone do not decide which battery is “better.” A useful evaluation must also consider:
- Cell chemistry and pack architecture
- Continuous and peak current limits
- BMS strategy
- Pack mass and energy density
- Connector and cable capacity
- Temperature behavior
- Charging requirements
- Serviceability and replacement cost
This creates an opportunity for technically accurate educational content. Customers increasingly want to understand why two batteries with similar amp-hour ratings can behave very differently under high load.
5. Intelligent Control Is Becoming Part of the Riding Experience
Modern electric dirt bikes use software to shape how the available power reaches the rear wheel.
The Light Bee 2 promotes traction control, adjustable power modes, regenerative braking adjustment and other rider-assistance functions. The 2026 Light Bee X also uses an MTPA/MTPV FOC controller and adjustable throttle response.
The TRB Apex E100 Pro follows the same broader industry movement toward advanced motor control. It combines FOC, MTPA and field weakening in a dual closed-loop architecture, with support for regenerative braking, speed-mode selection and Bluetooth app adjustment.
These systems matter because maximum power is only useful when the rider can control it. Controller calibration influences low-speed smoothness, throttle response, current limiting, regenerative braking and high-speed motor operation.
The market is therefore shifting from “How many kilowatts does it have?” to a more complete question: “How well does the motorcycle manage those kilowatts?”
6. Chassis, Brakes and Thermal Management Must Catch Up
As lightweight platforms move into higher power classes, the supporting hardware becomes more important.
Higher power can increase acceleration loads, braking demand, chain and sprocket stress, battery temperature and controller temperature. A credible high-performance electric dirt bike therefore needs more than a powerful motor.
Customers should examine:
- Frame and swingarm construction
- Suspension travel and damping adjustment
- Brake-caliper and rotor capacity
- Wheel and tire specification
- Drivetrain strength
- Battery mounting and impact protection
- Motor and controller cooling
- Fault detection and temperature derating
The Light Bee 2's published emphasis on its forged frame, integrated drivetrain and braking system shows that manufacturers recognize this requirement. TRB takes the same system-level view when presenting the Apex motor, controller, battery and off-road chassis together.
7. What This Trend Means for Buyers
The arrival of products such as the Light Bee 2 gives buyers more choices, but it also makes specification comparison more difficult.
Before selecting a platform, define the intended use:
- Lightweight trail riding
- Private-land recreation
- Technical off-road riding
- High-output performance builds
- Farm or utility operation
- Dealer, distributor or OEM programs
Then compare products using consistent definitions. A 24 kW production peak, a 35 kW controlled-test peak and a 52 kW instantaneous motor peak should not be placed in one table without explaining the conditions behind each number.
Weight, battery energy, gearing, thermal limits, chassis setup, spare parts and service support may be as important as the maximum power figure.
8. Where the TRB Apex Fits
The TRB Apex represents a high-output system route within the evolving electric off-road market. Its confirmed core specification includes:
| Item | TRB Apex specification |
|---|---|
| Motor type | Mid-mounted PMSM |
| Rated motor power | 26 kW |
| Instantaneous peak motor power | 52 kW |
| Battery | 72 V 45 Ah |
| Nominal battery energy | 3.24 kWh |
| Battery discharge rate | 15C |
| Continuous battery current | 300 A RMS |
| Peak battery current | 600 A |
| Controller | TRB Apex E100 Pro |
| Maximum controller input current | 250 A |
| Peak controller phase current | 800 A |
| Motor control | FOC + MTPA + field weakening |
TRB has not yet published confirmed curb weight, wheel torque, standardized range, acceleration or top-speed figures for this configuration. Those values should not be inferred from the electrical specifications alone.
The Category Is Growing Up
The Light Bee 2 is evidence that the lightweight electric dirt bike category is becoming more powerful, more integrated and more software-defined. That evolution benefits the entire market by encouraging better motors, stronger batteries, smarter controllers and more capable chassis systems.
It also raises the standard for technical communication. Customers need comparable definitions, transparent test conditions and complete system information—not only larger headline numbers.
TRB's approach is to describe the Apex as an integrated motor, battery, controller and chassis platform.

轻量化平台正在进入更高功率级别
2026 款 Light Bee X 的区域公开参数为 10 kW、72 V 35 Ah 和 59 kg，而 Light Bee 2 将公开峰值功率提高到 24 kW，同时保持 65 kg 的整备质量。这意味着轻量型林道车与更大型高性能电动越野摩托车之间，正在形成新的中高功率产品区间。
峰值功率越来越重要，也越来越容易被误读
轻蜂 2 页面同时出现 24 kW 峰值输出和研发受控测试记录 35 kW 两种表述，两者对应的运行条件并不相同。TRB Apex 则明确区分 26 kW 额定功率与 52 kW 瞬时峰值功率。
比较电动越野车时，应进一步确认：
- 数据是额定功率、稳定峰值还是瞬时峰值？
- 峰值能够维持多长时间？
- 测试时的电量和温度是多少？
- 限制来自电机、控制器、电池、BMS 还是热管理？
- 功率是在电气端、电机轴端还是车轮端测得？
只有口径一致，数字比较才有意义。
动力总成正在从零部件组合走向系统集成
新一代电动越野车不再只强调电机。电池、BMS、控制器、电机、减速机构、线束、连接器、散热和软件标定需要作为整体设计。
轻蜂 2 强调 EVO-2 集成动力系统；TRB Apex 则通过 72 V 45 Ah 电池、E100 Pro FOC 控制器和中置电机形成高输出动力平台。两者路线不同，但都反映了同一个行业方向：决定整车表现的是系统匹配，而不是单个最大参数。
电池与智能控制成为新的竞争重点
轻蜂 2 把半固态电池、能量密度、放电性能和低温表现作为核心卖点。TRB Apex 的确认电池规格为 72 V 45 Ah / 3.24 kWh，15C 放电倍率、300 A RMS 持续电流和 600 A 峰值电流。
与此同时，FOC、MTPA、弱磁控制、牵引力控制、动力模式和能量回收正在改变电动越野车的骑行体验。市场关注点正在从“有多少千瓦”逐渐转向“如何把这些功率稳定、平顺地传递到车轮”。
高功率必须由底盘与热管理共同支撑
更高功率会增加制动、传动、线束、电池和控制器的负荷。因此选购高性能电动越野车时，还应检查车架、摇臂、悬架、制动器、轮胎、传动强度、电池防护和温度降功率策略。
TRB Apex 的市场位置
TRB Apex 当前确认的核心信息包括 26 kW 额定电机功率、52 kW 瞬时峰值功率、72 V 45 Ah 电池以及峰值输出相电流 800 A 的 E100 Pro 控制器。
TRB 尚未公布该配置的确认整备质量、轮上扭矩、标准续航、加速和最高速度，因此不应仅根据电气参数推测这些结果。
轻蜂 2 的出现说明轻量化电动越野车正在向更高功率、更高集成度和更强软件控制能力发展。对于消费者而言，未来最重要的不只是看谁的数字更大，而是看功率口径是否透明、系统是否匹配、整车是否适合自己的使用场景。
