Electric Motorcycle Import Guide: What Dealers Need to Know About Electric Motorcycle Specs

Introduction: A Letter to Fuel Motorcycle Dealers

You have been selling fuel motorcycles for years. You understand displacement. You understand cylinder count. You understand carburetor models. But now customers are starting to ask about electric motorcycles. You pick up a spec sheet – and you see kW, Ah, MOSFET count, magnet grade. What do these numbers actually mean?

This article does not hype electric over fuel. It does not bash fuel bikes. It simply translates the electric motorcycle spec sheet into language you already understand. After reading this, you will be able to:

• Look at any electric motorcycle spec sheet and understand what it says
• Explain to customers why one model differs from another
• Ask suppliers the right questions – and not get intimidated by numbers

Chapter 1: Battery Placement – Where the Weight Goes Determines Half the Riding Feel

Most dealers look at motor power and battery capacity first. Nobody asks where the battery is actually located. But the battery is the heaviest single component in an electric motorcycle (20–40 kg for lithium, even more for lead-acid). Where it sits determines how the bike handles, how stable it feels, and even how safe it is.

On Scooters

Under the floorboard (most common): The battery sits beneath the rider‘s feet. Low center of gravity, stable cornering. Depending on chassis design, it may limit ground clearance compared with some under-seat layouts.

Under the seat: Better ground clearance, better through rough roads. The trade-off: higher center of gravity makes the bike feel less stable when cornering.

On Traditional Motorcycles

These bikes have no floorboard and no large under-seat compartment. The battery is typically mounted where the fuel engine used to be – in the central frame area. This keeps the weight low and centered, but the shape and size of the battery must match the original engine bay, which limits how large a battery you can fit.Some dedicated electric motorcycle platforms are designed around the battery pack itself, rather than adapting an existing engine bay.

What to Ask Suppliers

• “Where is the battery mounted?” – if they can‘t answer clearly, that’s a red flag.
• “What is the ground clearance?” – especially important if your local roads are rough.
• “Can the battery be removed for charging or replacement?” – important for apartments or fleet use.

Chapter 2: Battery – The Real Spec That Determines Range

Battery specs are where most dealers get confused. Let‘s clear it up once and for all.

Voltage (V) and Capacity (Ah) – Why You Can’t Look at One Without the Other

Battery suppliers list specs like “60V20Ah” or “72V20Ah”. At first glance, both have “20Ah” – so you might think they hold the same amount of energy. This is where most dealers get misled.

Ah alone is meaningless without Voltage.

Here is the math:

• 60V × 20Ah = 1,200Wh (1.2kWh)
• 72V × 20Ah = 1,440Wh (1.44kWh)

Both batteries are labeled “20Ah”, but the 72V battery stores 20% more energy – 240Wh more. That 240Wh translates directly into extra range. In real-world riding, a 72V20Ah scooter will consistently outlast a 60V20Ah scooter under the same load and speed conditions.

The takeaway: You cannot compare batteries by Ah alone. The real unit that measures “how much fuel is in the tank” is Wh (watt-hour) – or kWh (kilowatt-hour). Voltage and capacity together tell the full story.

Battery Types: Lead-Acid vs. NMC vs. LFP – Which One to Import?

Different battery chemistries suit different markets and use cases. Here is what you need to know:

Dealer Selection Guide by Market

• Lead-acid: Only for ultra-budget segments where customers cannot afford lithium. Heavy, short life, poor in cold weather. Not recommended for most markets.
• NMC (lithium): Best for performance-oriented markets where customers want light weight and maximum range. Suitable for temperate climates.
• LFP (LiFePO₄): Best for commercial fleets, delivery services, and warm-climate countries. The long cycle life (2000+ charges) means lower total cost of ownership over the vehicle‘s lifetime. The cold-weather weakness is
• a factor only in markets with real winters.

The BMS and Emerging Battery Tech – The Brains and the New Sodium-Ion Wave

While fuel motorcycles rely on an ECU to manage fuel maps, electric motorcycles rely on a Battery Management System (BMS) to act as the primary safety brain of the battery.

What the BMS Does:
A lithium battery pack is made of hundreds of individual cells. The BMS monitors the temperature of the pack, balances the voltage of each individual cell to prolong battery life, and instantly shuts down power in case of a short circuit or overcharging. A high-quality BMS is what prevents battery damage and ensures absolute safety.

The 2026 Market Update: Sodium-ion (Na-ion) Batteries:
While NMC and LFP remain the dominant lithium chemistries, the market has introduced Sodium-ion (Na-ion) batteries. Utilizing sodium instead of lithium, this emerging technology is cheaper, highly safe, and solves a major pain point of LFP batteries: cold weather. Many sodium-ion batteries can maintain over 90% of their capacity in sub-zero temperatures (down to -20°C), making them an excellent budget-friendly alternative for cold-climate dealerships. Note that exact performance varies by manufacturer.

Chapter 3: The Motor – Hub vs. Mid-Drive, Magnets, Coils, and Oil Cooling

Motor Layout: Hub Motor vs. Mid-Drive Motor

Before digging into internal specs, understand where the motor is actually located – this affects cost, maintenance, and ride feel.

Dealer takeaway: Hub motors are simpler and cheaper – great for volume sales. Mid-drive motors are more expensive but offer better handling and performance – better for building a premium brand reputation.

Motor Core Component #1: The Magnets

Magnets sit on the rotor and determine the motor’s power density and efficiency. Five specs matter:

Honest advice for dealers: You will not open a motor to count magnets. But you can ask the supplier: “What magnet grade and height are you using?” If they cannot answer, you know where they stand.

Coils: Round Wire vs. Flat Wire

Coils are the windings on the stator that generate the rotating magnetic field.

• Round wire : Traditional method. Round wires leave gaps between them. Copper fill rate is lower – meaning less copper, higher resistance, more heat.
• Flat wire / Hairpin : Rectangular wires stacked like planks. Copper fill rate is significantly higher. More copper in the same space means lower resistance, less heat, and higher power density.

Think of it like packing a shipping container: round boxes leave gaps; square boxes fill every corner. Flat wire motors use the available space more efficiently.

Turns and Wire Thickness

Turns: The number of times the wire wraps around each stator tooth.

• More turns = higher inductance, better low-end torque, but lower top speed
• Fewer turns = lower inductance, higher top speed, but weaker initial torque

Wire thickness: Thicker wire carries more current – higher power ceiling. Thinner wire means less current but easier to wind.

Dealer translation: A motor with more turns and thinner wire is a “torque motor” – great for hill climbing and heavy loads. Fewer turns with thicker wire is a “speed motor” – better for flat highways and higher top speed. There is no “better” – only “better for the use case.”

Oil-Cooled Motors

Some premium electric motorcycles add an oil cooling system – dielectric oil flows through the motor to directly cool the windings and magnets.

• Pros: Higher sustained power, less thermal degradation, better for high-speed highway riding or long delivery shifts
• Cons: Higher cost, more complex sealing
• When it matters: If your customer is a food delivery rider doing 8 hours a day, oil cooling is a genuine benefit. For casual commuters, it is overkill.

kW to CC – How to Translate Electric Power into Engine Displacement

Fuel dealers think in engine displacement (50cc, 125cc, 250cc). Looking at a spec sheet showing “2kW” or “10kW” can be confusing. To help you position your inventory, here is a rough translation of electric motor power into the traditional CC classes you already know. Important: This is only a general guide to help you understand acceleration and top-speed feel for market positioning—it is not a direct conversion and must not be used to substitute for official vehicle classification regulations in different countries.

Under 1.5 kW (Roughly 50cc Feel)

• Market Segment: Light city scooters, food delivery, and budget commuters.

• Performance: Top speeds are typically restricted to around 45 km/h. In European and western markets, these often fall under “L1e” class regulations (note that L1e allows up to 4 kW rated continuous power), which may require simpler licensing and are highly popular for urban fleets.

3 kW to 5 kW (Roughly 110cc to 125cc Feel)

• Market Segment: The high-volume “sweet spot” for daily commuters.

• Performance: Top speeds range from 70 to 90 km/h. Because electric motors deliver peak torque instantly, these models will consistently beat their 125cc fuel counterparts off the line.

10 kW and Above (Roughly 250cc to 400cc Feel)

• Market Segment: Premium sport models, highway cruisers, and performance enthusiasts.

• Performance: Top speeds exceed 120–140 km/h, offering rapid acceleration and sustained high-speed performance.

Regenerative Braking vs. Engine Braking – The “Free Fuel” System

Every fuel motorcycle rider is familiar with “engine braking”—the resistance felt when rolling off the throttle, which slows the bike down without using the mechanical brakes. Electric motorcycles utilize this same physical concept through a system called Regenerative Braking (Regen).

How it Works:
When the rider rolls off the throttle or lightly squeezes the brake levers, the controller reconfigures the electric motor to operate as a generator. This creates a drag torque that slows the vehicle down, while converting the bike’s slowing momentum back into electricity and feeding it directly into the battery.

The Dealer Translation:
Instead of wasting kinetic energy as heat, the regen system turns braking into a passive charging event.

Why it Matters to Your Customers:

• Extended Range: It acts as a passive charging system, adding 5% to 10% more range during typical stop-and-go city riding.

• Lower Maintenance Costs: Because the motor handles a massive portion of the braking force, brake pad wear is cut significantly. Your customers will spend less on replacing brake pads and rotors.

Chapter 4: The Controller – What Does “MOSFET Count” Actually Mean?

MOSFETs Are Electronic Switches

Controllers use MOSFETs to switch current on and off rapidly. In dealer language, these are the “valves” that control how much power flows from the battery to the motor.

When a spec sheet says “12-tube controller”, it means there are 12 MOSFETs inside.

• 6-tube: Entry-level
• 9-tube: Commuter grade
• 12-tube: Performance grade
• 15-tube and above: High-power

But here is the catch: Tube count is like saying “how many valves” – but the valve size matters just as much as the count. A 12-tube controller with small MOSFETs can be weaker than a 9-tube controller with large MOSFETs.

The Rise of SiC and IGBT: as electric motorcycles move into higher voltages and premium performance, the technology under the hood has evolved significantly. In modern, high-voltage (96V and above) or high-power performance electric motorcycles, standard silicon MOSFETs are increasingly replaced by Silicon Carbide (SiC) MOSFETs or IGBT (Insulated-Gate Bipolar Transistor) controllers.

Dealer question to ask: “What is the total current rating of the controller?” If the answer is “50A” or “80A”, that tells you more than the tube count alone.

Voltage, Current, and Power – How They Really Relate
But a controller’s performance isn’t just about MOSFET count or current rating—you also need to understand how voltage, current, and power interact. The basic formula is Power (W) = Voltage (V) × Current (A). However, the roles of voltage and current are different.

Voltage sets the theoretical speed ceiling, but current delivers the actual power. Motor back‑EMF is proportional to speed, so higher voltage raises the maximum possible RPM (the “speed limit”). But reaching that limit requires enough power, which comes from current. If current is insufficient, the motor won’t have enough torque to push against wind and load resistance to hit that high‑speed ceiling. And current is heavily constrained by heat: copper losses increase with the square of current (I²R), so doubling current generates four times the heat. That heat can quickly damage the controller and motor. Therefore, the real‑world top speed and output power depend on both the voltage potential and the available current, with thermal management as the final bottleneck.

What does the datasheet actually tell you? When a controller manufacturer lists “maximum input current” or “rated current”, that figure almost always refers to the bus current – the DC current drawn from the battery. This is the value you should focus on when comparing controllers. But there is also a phase current (the AC current delivered to the motor phases), which can be several times higher than the bus current, and it is rarely printed on the front page of the spec sheet. Unless explicitly stated, the big “80A” or “100A” number is the bus current.

Bus Current vs. Phase Current – The Most Common Data Trap
Controller spec sheets often list two different current values. Here is what they mean:

The critical point: phase current can be much larger than bus current. Structurally, the controller is a 3‑phase DC‑AC inverter (converting battery DC to motor AC). However, in terms of voltage/current regulation, its PWM chopping behavior acts exactly like a step‑down (buck) DC‑DC converter. At low speed (e.g., climbing a steep hill from a standstill), the controller chops high battery voltage down to a much lower average phase voltage. The motor’s copper windings act as inductors, smoothing the chopped energy and efficiently converting a lower DC bus current into a much higher AC phase current. For example, a 96V, 300A bus current controller may output 800‑900A of AC phase current to the motor windings, generating massive starting torque.

Note on Nomenclature (Critical for Real‑World Selection): In popular high‑performance controllers like the FarDriver series, model numbers such as “72680” or “72450” refer to the peak phase current (680A and 450A respectively), while the actual maximum bus current drawn from the battery is lower (350A and 200A respectively). Do not confuse the model suffix with your battery’s discharge requirement – your BMS must handle the bus current, not the phase current!

Industry rule of thumb – estimating practical continuous power:
Strictly speaking, this is not a physical law formula (the real physics is simply P = V × I, without any “÷2”). Instead, it is a tuning rule of thumb widely used in the electric motorcycle community to quickly estimate the sustainable continuous mechanical power that a controller can deliver to the motor.

Controller practical continuous power ≈ Bus current × Rated voltage ÷ 2

Why divide by 2? While Voltage × Bus current gives the peak electrical input power from the battery (e.g., 72V × 350A = 25.2 kW), the sustained mechanical power delivered to the road is roughly half of that due to conversion efficiency losses, duty cycle limits, and thermal constraints. In practice, a 350A controller does not output 25 kW continuously; it typically sustains only about 12‑15 kW. Hence, this “÷2” rule perfectly estimates the practical rated motor class the controller can run sustainably.

Matching Principles – Voltage, Current, and Power

1. Controller continuous power should generally match or exceed the motor’s rated continuous power.
   Both controller and motor ratings are thermal ratings. In many mass‑produced bikes, the controller’s continuous rating is actually set equal to, or even slightly below, the motor’s rated power – because the motor’s rating is also a thermal limit. As a dealer, your benchmark is: match or slightly exceed, but do not grossly undersize.
2. Voltage must match
   Battery, BMS, controller, and motor must all have the same nominal voltage. A 48V system cannot use a 72V controller, and vice versa.
3. Leave current headroom
   The controller’s maximum output current must be greater than the motor’s rated current. Also, the BMS continuous discharge current must be ≥ the controller’s maximum bus current, otherwise the battery becomes the bottleneck.
4. Continuous power matters more than peak power
   • Continuous power – the power the controller can sustain indefinitely under the manufacturer’s specified cooling conditions (heat sink, airflow, etc.).
   • Peak power – the maximum power the controller can deliver for a short, specified duration (typically from 30 seconds up to a few minutes, as defined by the manufacturer), determining acceleration bursts.

   The peak‑to‑continuous ratio is typically 1.5‑2.5. A higher ratio gives stronger burst but demands more from the controller and battery.

Translation for dealers: Matching the three components (battery, controller, motor) is like plumbing – matching voltage is like matching pipe diameters, adequate current is like sufficient water pressure, and proper power is like the right water volume. A small battery feeding a large motor gives weak starts; a large battery feeding a small motor wastes cost.

Matching controllers to the motor power classes (from Chapter 3)

• Under 1.5 kW (≈50cc feel): Use a 48V or 60V system. Recommended controller bus current: 30A – 40A. Example: 48V × 35A ≈ 1.68 kW, comfortably covering the motor. As a rule of thumb, pick a controller whose peak power rating (maximum electrical input) is 1.5 to 2.5 times the motor’s rated continuous power, keeping costs reasonable without oversizing the controller hardware.
• 3 kW to 5 kW (≈110cc–125cc feel): Use 72V as the standard. Recommended bus current: 50A – 80A. At 72V, 50A gives 3.6 kW and 80A gives 5.76 kW, which covers this range well. Many popular controllers (e.g., VOTOL EM‑150 series) are designed exactly for this power band.
• 10 kW and above (≈250cc–400cc feel): Use 72V, 96V, or higher. Bus current should start at 100A for continuous operation, and peak currents can be much higher. For example, 10 kW at 72V requires about 140A continuous; at 96V, about 105A. In practice, high‑performance controllers for 10 kW motors often have peak bus currents of 300A – 500A. Examples include the GTAKE D03 series (72V, 320‑350A peak) and ATO 10 kW controllers (48V, 500A peak bus).

These recommendations give you a solid starting point. Always confirm with your supplier the continuous vs. peak current ratings, the specific duration for peak ratings, and make sure the battery BMS can deliver the required bus current without tripping.

Chapter 5: Charging – The Infrastructure Reality

When a customer asks about charging, dealers often focus on the bike alone. But the real question is: What does the customer have available to plug into?

Slow Charging (Standard AC)

Most electric motorcycles include a slow charger that plugs into any household outlet. Charge time depends on battery size and charger power – typically 6–8 hours for a full charge.

Dealer message to customers: For daily city commuting, you do not need to fully charge every night. If you ride 30–40 km per day, plug in for a few hours and you are fine. Lithium batteries do not need to be fully charged every cycle. Do not turn charging into a chore.

Fast Charging – The Infrastructure Problem

Most electric motorcycles rely on standard AC charging. Some premium models support faster AC charging or DC fast charging, but compatible infrastructure varies widely between markets. There is no widely available public fast-charging network for motorcycles in most markets.

Dealer reality check: Unless your customer has a dedicated DC fast charger installed at their depot or home, fast charging is not a practical selling point. For most dealers, the honest answer is: “This bike supports slow charging from any wall outlet. Fast charging is technically possible but requires infrastructure that does not exist yet.”

Battery Swapping

Some markets (Battery-swapping networks are most developed in parts of Asia, with pilot programs and growing adoption in several African countries.) use battery-swapping networks – the customer rents a battery and swaps it at a station in seconds.

Dealer translation: This makes sense for customers who cannot charge at home (apartments, no garage) or for high-mileage fleets. For most private buyers, swapping adds recurring cost. Calculate the math before recommending it.

Additionally, educating your customers on proper daily charging habits is the best way to prevent premature battery degradation.

Conclusion: You Already Know More Than You Think

Switching from fuel to electric does not mean throwing away everything you know.

The underlying logic is the same – just different units. When you pick up an electric motorcycle spec sheet, ask these five questions:

1. Where is the battery located? – affects handling and ground clearance
2. What is the battery energy (kWh) and type? – not just Ah, calculate kWh
3. Hub motor or mid-drive? – commuter vs. performance
4. What is the controller rating? – not just tube count, ask current (A)
5. How does the customer charge? – home outlet or infrastructure-dependent?

If you can answer these five questions, you understand more than 90% of fuel motorcycle dealers about electric motorcycles. Once you know how to read the specs, the next step is putting together your full business plan – from market entry to daily operations.
