An electric motorcycle's performance story is told in curves — not single-point peak numbers. The relationship between motor speed and output torque across the operating range, the way efficiency rises and falls as load changes, the actual energy drawn from the battery over a 100km simulated road run — these are the figures that matter to regulators, distributors, and end users, and none of them can be reliably established without a controlled load environment.
Road testing cannot provide this. Wind, gradient variation, temperature, and traffic conditions introduce too many uncontrolled variables for repeatable, certification-grade data. A closed test track eliminates traffic but not weather, and it cannot simulate a consistent load profile or generate the torque-speed curve data that motor efficiency analysis requires.
A chassis dynamometer for electric motorcycles solves this by reproducing road resistance inside a controlled lab environment: a servo-driven roller applies a programmable load torque to the rear wheel while the vehicle's own motor drives the roller, and precision sensors capture torque, speed, voltage, and current simultaneously throughout the run. The result is complete, repeatable, documentable performance data — produced in a single test setup without leaving the factory floor.
For electric motorcycle manufacturers targeting export markets in Southeast Asia, Europe, and South America — where importer and distributor due diligence increasingly includes requests for verified performance curves, not just specification sheets — this kind of in-house test capability has shifted from a laboratory luxury to a production necessity.
The FH-DM076 is a rear-axle-loaded, center-axle-driven chassis dynamometer built specifically for electric motorcycle performance and efficiency testing. The vehicle is mounted once, pneumatically clamped into the fixture, and tested through all required sequences under computer control — with no manual measurement at any point during the run.
At the core of the system is a 26kW servo load motor that applies programmable resistive torque to the rear roller throughout the test, paired with a 500N·m precision torque and speed sensor that captures the full mechanical output signal with 100μs frequency response — fast enough to capture transient torque behavior that slower sensors would smooth over.
The onboard computer simultaneously measures:
Drive torque (load side) and transmission torque (output side) — both curves displayed in real time
Rotational speed (RPM)
Voltage and current from the power supply
Calculated load power and input power
From these, the system automatically generates five characteristic performance curves:
Curve | Expression | What It Tells You |
|---|---|---|
Speed-Torque | n = f(T) | How torque varies across the speed range |
Load characteristic | T = f(n) | How speed responds to increasing load |
Efficiency | η = f(n) | Where in the speed range the motor is most efficient |
Input power | P1 = f(n) | Electrical energy draw across the range |
Output power | P2 = f(n) | Mechanical output across the range |
These five curves together give engineers and QC teams a complete motor and drivetrain characterization — not just peak figures.
Electric motorcycle testing spans several overlapping regulatory frameworks depending on the target market:
GB/T 24158 — Electric motorcycle and moped general technical specifications
GB/T 24157 — Electric motorcycle and moped energy consumption and range test methods
GB/T 28382 — Safety requirements for electric motorcycles and mopeds
These GB/T standards define the test methodologies for max speed, range, and energy consumption that the FH-DM076 is built to execute, and form the basis of China's type-approval process for electric two-wheelers above the 25km/h e-bike threshold.
ISO 13064 — Test methods for battery-powered electric vehicles (applicable segments)
ECE R6 / UN Regulation 10 — Electromagnetic compatibility, referenced in EU type approval for L-category vehicles
ARAI / CIRT test protocols (India) — India's electric two-wheeler certification requirements, increasingly relevant as Indian buyers request pre-verified performance data
Across Southeast Asia, Latin America, and emerging African markets, distributors and fleet buyers are increasingly requesting factory-generated performance curve documentation — torque-speed curves, efficiency maps, and range test logs — as part of purchase due diligence. The FH-DM076's Excel export and five-curve analysis directly produce the file formats these buyers request.
The FH-DM076 covers the full performance test matrix for electric motorcycles in a single setup:
Maximum speed test — verifies top speed under load at rated battery voltage
Road simulation test — programmable load profile replicating flat road, headwind, and gradient resistance
Acceleration performance test — 0 to target speed under standardized load, auto-logged
Chassis dynamometer road test — full drivetrain characterization under road-equivalent rolling resistance
Constant-speed hill-climb test — verifies torque output can sustain a set speed on a fixed simulated gradient
Constant-gradient hill-climb test — verifies the vehicle can maintain motion on a set gradient regardless of speed
0–100km acceleration test — timed acceleration run for performance characterization
Maximum power test — identifies peak output power point from the P2 = f(n) curve
Range (mileage) test — full-charge to depletion run at rated speed, total distance auto-logged
Energy consumption per 100km test — real-time voltage, current, and mileage logging; auto-calculates kWh/100km
Drive torque curve and transmission torque curve — displayed simultaneously
n = f(T): Speed-torque characteristic
T = f(n): Load characteristic
η = f(n): Efficiency characteristic
P1 = f(n): Input power characteristic
P2 = f(n): Output power characteristic
The FH-DM076 includes an integrated braking function, enabling coast-down resistance measurement and controlled deceleration testing within the same setup.
The vehicle is secured by a pneumatic clamping system — consistent clamping force every time, no variation from operator technique. The fixture is designed for tool-free adjustment to accommodate different motorcycle frame widths and wheelbase configurations.
A cylinder mechanism adds 0–200kg of adjustable counterweight to the frame during testing — simulating rider mass and allowing manufacturers to test under realistic load conditions, not just unloaded vehicle performance. The weight range covers the full spectrum from lightweight urban electric motorcycles to heavier performance models.
The center-axle drive, rear-axle load configuration means the load servo motor applies resistance precisely at the rear wheel contact point — the same point at which road resistance acts in real riding. This eliminates the measurement error introduced by drivetrain-interposed dynamometer designs.
The integrated Dayang torque and speed sensor has a 100μs frequency response — sufficient to capture transient torque spikes that occur during acceleration and load transitions, giving engineers accurate data on peak as well as sustained torque behavior.
Motor model specifications and pass/fail thresholds are entered once and stored — the system supports over 2,000 motor model profiles, making the bench practical for contract manufacturers or test labs handling diverse customer product ranges without re-entering parameters for each run.
Operator and administrator accounts with separate password protection. Administrators can add or remove operator accounts, set threshold parameters, and control access to stored model data — a practical feature for multi-shift production environments where data integrity and parameter security matter.
The dynamic simulation display shows the active test item in real time alongside live numeric readings of all monitored parameters — designed for operators to read at a glance during a running test without needing to interpret raw data screens.
Emergency stop button on the work surface — all motion axes hold position on activation
Manual main power breaker operable from outside the control cabinet door
24V low-voltage internal lighting for safe cabinet inspection
220V service socket inside the cabinet for maintenance laptop connection
Ventilation and rodent exclusion on the control cabinet

100μs torque sensor response captures transient load events that 1ms or slower sensors average out — critical for accurate peak torque measurement during acceleration tests.
±0.5% torque accuracy puts measurement uncertainty well inside the tolerance bands of GB/T and ISO electric motorcycle test methods, so test results are defensible without correction factors.
0–200kg adjustable counterweight covers both unloaded vehicle characterization and full rider-equivalent load testing — important because motor efficiency curves shift meaningfully under load, and unloaded data alone does not represent real-world performance.
2,000+ model storage means a factory running QC tests on multiple product lines or a test lab serving multiple clients never needs to re-enter threshold parameters — reducing setup error and saving test time per vehicle.
The electric motorcycle is positioned on the test bench and secured via pneumatic auto-clamp. Counterweight is set to the required test mass (0–200kg range). Removable footpegs and riding frame are attached if needed for the test configuration.
The operator selects the motor model from the stored profile library (or enters a new model). Pass/fail thresholds, test sequences, and curve display settings are confirmed. Once set, parameters are locked for the run.
Manual button start initiates the test sequence. The vehicle's motor powers the roller; the 26kW servo load motor applies programmable resistive torque throughout the run. The system executes each test phase automatically — no operator intervention required.
All five characteristic curves plot live on the dynamic display as the test progresses. Drive torque and transmission torque curves are shown simultaneously. Live numeric readouts of speed, torque, voltage, current, and calculated power values update in real time.
On completion, all logged data is auto-saved to the operator's profile. Results are reviewed on screen or exported directly to Excel in the configurable report format. Data for all 2,000+ stored models remains retrievable and queryable at any time.
The five simultaneous performance curves give engineers a full motor and transmission picture from one test run — eliminating the need for separate motor bench tests, road coast-down tests, and manual efficiency calculations.

Five-curve Excel exports give distributors and import certification bodies the data format they request — torque-speed curves, efficiency maps, power curves, and range logs — directly from the production test bench, without a separate lab engagement.
The 100μs torque sensor response and simultaneous dual-curve display (drive torque + transmission torque) make the FH-DM076 useful for motor and transmission development work — comparing candidate motor specifications under identical load conditions and identifying drivetrain efficiency losses between motor output and wheel delivery.
When evaluating chassis dynamometers for electric motorcycle testing, the following factors are worth examining carefully:
A dynamometer's data quality is ultimately limited by its torque sensor. For electric motorcycle testing where transient torque behavior during acceleration is a key metric, frequency response of 100μs or better matters — slower sensors will underreport peak torque. Accuracy of ±0.5% or better ensures results align with independently measured reference values.
The load motor must comfortably absorb the test vehicle's full output at all test speeds — not just at peak power. Verify that the rated continuous load torque at your vehicle's maximum test speed is within the servo motor's continuous-duty envelope, not just its peak rating.
Some compact dynamometer designs load via a front roller contacting the rear tyre. Rear-axle loading, as used in the FH-DM076, applies resistance at the actual wheel-road contact geometry, giving more accurate rolling resistance simulation and better correlation with road test data.
If your product range spans lightweight urban commuter models and heavier performance motorcycles, confirm the counterweight system covers the full mass range — and that the adjustment mechanism is practical for quick changeover between different test weights on a production line.
Not all dynamometer software generates efficiency and power curves automatically. If your use case includes motor characterization for R&D or supplier qualification — not just pass/fail QC — confirm the system produces the η = f(n), P1 = f(n), and P2 = f(n) curves natively, without requiring post-processing in separate software.
An electric motorcycle manufacturer with three motor variants across its product range used a chassis dynamometer to generate comparative efficiency maps for all three under identical load conditions — enabling the engineering team to select the variant with the best efficiency at urban commuting speeds (30–60km/h) rather than at the peak power point that motor supplier datasheets typically emphasize.
An OEM supplying electric motorcycles to a Southeast Asian fleet operator used factory-generated torque-speed curves and range test logs to satisfy the technical documentation requirement in the operator's purchase specification — shortening the pre-order validation period from eight weeks (waiting for third-party lab results) to under two weeks.
A contract manufacturer producing electric motorcycles for multiple brands used the 2,000-model profile storage to maintain separate, locked QC threshold sets for each client's product — preventing operators from accidentally running one client's vehicle against another's pass/fail criteria.
The bench is designed for electric motorcycles up to 100km/h test speed, with 0–200kg adjustable counterweight to cover vehicles across the urban commuter to mid-range performance segment. The adjustable pneumatic fixture accommodates different frame widths and wheelbase configurations.
Speed-torque (n = f(T)), load characteristic (T = f(n)), efficiency (η = f(n)), input power (P1 = f(n)), and output power (P2 = f(n)). Drive torque and transmission torque curves are also displayed simultaneously in real time.
The Dayang torque-speed sensor has a rated accuracy of ±0.2%–±0.5% (full scale), nonlinearity of ±0.1%–±0.3%, and repeatability of ±0.1%–±0.2% — within the tolerance requirements of GB/T electric motorcycle test methods.
