Dual-Roller Scooter & Roller Skate Durability Test Machine (FH-HB3309)

Two rollers. Two obstacle blocks. One machine that tests scooters and roller skates the way they actually get used.

The FH-HB3309 uses a chain-driven dual-roller system to simulate the road conditions a scooter or roller skate encounters in real use — continuous rolling load, periodic 5mm obstacle impacts, and hill-climb resistance — under a 100kg test weight. Two adjustable-spacing rollers (650–1,050mm) accommodate scooters with different wheelbases; two 5mm impact blocks on the roller surface introduce the periodic obstacle impacts specified in CNS6263-11; and real-time monitoring tracks mileage, speed, and obstacle count throughout the run. Built to CNS6263-11, this machine is also applicable to roller skates, inline skates, and other wheeled products requiring dynamic durability evaluation.

Why Dual-Roller Testing Covers What Single-Roller Tests Miss

A scooter's two wheels are not located at the same point. When a scooter rolls over a road surface, front and rear wheels encounter obstacles and surface irregularities independently — at different moments in time, transmitting different impulse forces into different structural regions of the frame. A single-roller test bench contacts only one wheel at a time and cannot replicate this simultaneous two-wheel loading condition.

A dual-roller test bench places both wheels on rollers simultaneously. When an obstacle block on the front roller produces an impact, the frame responds under the combined constraint of both wheels — front wheel impacting, rear wheel still rolling — which creates the deck bending, stem loading, and folding joint stress state that actually occurs during real obstacle encounters. This is the load condition CNS6263-11 is designed to test.

For roller skates and inline skates, the dual-roller arrangement contacts multiple wheels of the skate frame simultaneously, replicating the distributed load across a full skate chassis rather than isolating a single wheel — more representative of how skate frames fatigue in use.

The adjustable 650–1,050mm roller spacing means the FH-HB3309 accommodates the full range of scooter wheelbases in the market — from compact children's scooters to full-size adult electric and kick scooters — without fixture changes.

Overview of the FH-HB3309 Test Machine

The FH-HB3309 is a chain-driven dual-roller road simulation durability tester for scooters, roller skates, and similar wheeled sports and mobility products. A motor drives a sprocket that rotates both rollers simultaneously via chain drive; roller speed is adjusted by varying motor speed through the control system. Two 5mm obstacle blocks are mounted on each roller, producing periodic impact events at the wheel-roller interface — simulating the 5mm surface irregularities specified in CNS6263-11 as the standard obstacle height for scooter and roller product durability testing.

The machine applies 100kg test weight to the vehicle under test, simulating adult rider mass distributed across the scooter's deck, stem, and wheel assemblies. A touchscreen control panel displays roller speed in km/h and remaining test time in real time; a 0–999,999 hour timer with power-loss memory ensures test continuity is maintained even if power is interrupted.

Hill-climb testing is supported — the roller system can be configured to simulate gradient resistance, verifying that the vehicle's drive mechanism (for electric scooters) or structural integrity (for kick scooters) meets the requirement under hill-climb load conditions.

Standards and Applicable Products

CNS6263-11 — Taiwan National Standard for Wheeled Sports Equipment

CNS6263-11 is Taiwan's national standard for scooters, roller skates, and related wheeled sports products. It specifies dynamic durability test requirements including:

• Roller speed and test duration for road simulation

• Obstacle height and frequency for impact endurance testing

• Load magnitude and distribution for rider weight simulation

• Pass criteria for structural integrity after the required test cycle count

The FH-HB3309 is designed and manufactured to CNS6263-11 specifications. Its 320mm roller diameter, 5mm obstacle block height, 100kg test weight, and chain-driven speed control system all match the parameters defined in the standard.

Applicable Products

Beyond scooters and roller skates, the FH-HB3309's adjustable roller spacing and flexible load system make it applicable to:

Main Test Functions and Applications

1. Dynamic Road Simulation Test 

Both rollers run simultaneously under the 100kg test weight, accumulating rolling cycles on wheels, bearings, axles, and frame joints at the programmed speed. This replicates the continuous road fatigue a scooter accumulates over thousands of kilometers of urban use — developing the deck flex fatigue, stem loosening, and wheel bearing degradation that standard static tests cannot predict.

2. Obstacle Impact Test

Two 5mm obstacle blocks are mounted on each roller. As the rollers turn, these blocks contact the scooter wheels at the programmed frequency — producing periodic impact loads at both wheel positions simultaneously. This simulates the kerb drops, road joints, and surface irregularities that generate the highest instantaneous structural loads during real scooter use. The machine logs the cumulative obstacle count in real time throughout the test.

3. Long-Distance Walking Simulation

The machine runs for the programmed duration — up to 999,999 hours — accumulating the equivalent distance of long-distance continuous use. Real-time mileage display shows accumulated equivalent distance throughout the run, giving operators immediate visibility into test progress without stopping the machine.

4. Hill-Climb Test

The FH-HB3309 supports hill-climb testing — configuring the roller system to simulate gradient resistance. For electric scooters, this verifies that the drive motor maintains adequate torque output under slope-equivalent load. For kick scooters, it verifies that the structural integrity is maintained under the combined deck bending and forward thrust forces of hill climbing.

5. Electric Scooter Range Monitoring

Real-time range monitoring tracks equivalent mileage throughout the test run. For electric scooters operating under their own power on the rollers, this provides a standardized indoor range figure — free from the weather, gradient, and rider-weight variability of outdoor road tests.

6. Static Load Test

With rollers stationary, the 100kg test weight is applied at the specified load points for the required duration. This tests creep, joint relaxation, and structural adequacy under sustained static load — the third test mode required alongside dynamic and obstacle testing for full product qualification.

Design Features of the FH-HB3309

Dual 320mm Rollers with Adjustable Spacing (650–1,050mm)

Two 320mm diameter rollers are mounted on the bench with spacing adjustable from 650mm to 1,050mm — covering the wheelbase range of children's and adult scooters currently on the market. Adjusting spacing requires no tool changes; the roller positions slide and lock at the required distance. Both rollers are driven simultaneously by the chain drive system, ensuring synchronized speed at front and rear wheels.

5mm Obstacle Blocks × 2 (Per CNS6263-11)

Two obstacle blocks, each 5mm in height, are mounted on each roller surface. At typical test speed, these blocks contact each wheel multiple times per minute — producing the periodic impact loads specified in CNS6263-11 for scooter and roller product dynamic durability testing. The obstacle count is logged in real time on the touchscreen display.

Chain-Drive Motor System with Speed Control

A motor drives both rollers via chain and sprocket, ensuring synchronized speed at both wheel contact points. Motor speed is adjusted via the control system to set the required roller surface speed in km/h — displayed on the touchscreen. Chain drive provides the torque and shock resistance needed for reliable operation under 100kg load with periodic obstacle impacts over long test durations.

100kg Test Weight Capacity

The machine is designed to carry 100kg test weight — equivalent to a fully-loaded adult rider. The weight is applied to the vehicle under test via the standard load fixture, distributing mass across the deck, handlebar, and seat positions appropriate to the vehicle type.

0–999,999 Hour Timer with Power-Loss Memory

The programmable timer covers the full range from 1 second to 999,999 hours — accommodating both short standardized test sequences and extended multi-week lifetime durability programs. Power-loss memory retains the elapsed time if power is interrupted during a long run, so the test continues from the correct count when power is restored rather than restarting from zero. This is a practical feature for extended overnight and multi-day tests in facilities with less than perfectly stable power supply.

Real-Time Monitoring: Mileage, Speed, Obstacle Count

The touchscreen displays three key metrics continuously throughout the test:

• Cumulative equivalent mileage — calculated from roller speed and elapsed time

• Current roller speed — in km/h, updated in real time

• Obstacle impact count — cumulative count of obstacle block contacts

This gives operators immediate test status visibility without stopping the run, and provides the data points needed for test report documentation.

Castored Base for Portability

Four heavy-duty caster wheels are mounted at the base of the machine, allowing the 500kg (fully loaded) bench to be moved within the test facility without disassembly or lifting equipment. This is practical for facilities where floor space is shared between multiple test programs.

Why These Specifications Matter

• Dual rollers at 650–1,050mm spacing are the geometry that makes the FH-HB3309 genuinely representative of two-wheel scooter loading: both wheels on rollers simultaneously means frame bending, stem stress, and folding joint loads are produced under the same constraint geometry as real riding. The 400mm adjustment range covers virtually all kick scooter and e-scooter wheelbases in the current market.

• 5mm obstacle block height matches the CNS6263-11 obstacle specification — the standard height that represents typical urban road surface irregularities (expansion joints, speed bumps, uneven paving) relevant to scooter use. Larger obstacles would represent abuse conditions; smaller obstacles would undertest.

• Power-loss memory on the 0–999,999h timer is essential for extended durability programs: a 200-hour test that resets to zero on a power interruption at hour 150 loses 75% of its elapsed test time. The memory function eliminates this risk.

• Chain drive vs. belt drive: Chain drive transmits motor torque to the rollers without the slip that belt systems exhibit under high load or impact events. Under 100kg test weight with 5mm obstacle impacts, belt slip would cause momentary speed variation at the obstacle event — producing a non-standard loading condition. Chain drive maintains consistent roller speed through the obstacle contact.

How the FH-HB3309 Testing Process Works

Step 1: Wheelbase Measurement and Roller Spacing Adjustment

The scooter or skate is measured for wheelbase. The front and rear rollers are adjusted to match the vehicle's wheel contact points and locked at the correct spacing within the 650–1,050mm range.

Step 2: Vehicle Mounting and Load Application

The vehicle is placed on both rollers with front wheel on the front roller and rear wheel on the rear roller. The 100kg test weight is applied at the appropriate load points for the vehicle type (deck and handlebar for standing-rider scooters).

Step 3: Test Parameter Setting

Test duration is entered on the touchscreen timer (in seconds, minutes, or hours as required by the standard or test program). Target roller speed is set. For hill-climb tests, the gradient resistance configuration is applied.

Step 4: Test Run

The motor starts, driving both rollers via chain to the set speed. The 5mm obstacle blocks contact both wheels at the obstacle frequency determined by roller speed. The touchscreen displays real-time speed, cumulative mileage, and obstacle count throughout the run. For electric scooters in range test mode, the vehicle's own motor drives against the roller resistance.

Step 5: Automatic Stop and Inspection

The timer stops the machine at the programmed duration. The vehicle is inspected for:

• Fracture or crack at deck, stem, folding mechanism, wheel axles

• Permanent deformation at any structural member

• Loosening at joints, fasteners, and folding lock mechanisms

• Wheel roundness and surface condition (for wear evaluation)

• Functional check of all safety-relevant mechanisms (brakes, folding lock)

Benefits for Manufacturers and Testing Labs

Simultaneous Two-Wheel Loading — More Representative Than Single-Roller Testing

The dual-roller geometry loads front and rear wheels simultaneously under the same 100kg test weight, producing the frame bending, stem stress, and joint loading that occurs during real riding. Single-roller benches load only one wheel at a time — adequate for wheel wear testing but not representative for frame fatigue or folding mechanism endurance.

Three Test Modes in One Setup

Extended Unattended Testing with Power-Loss Protection

The 999,999-hour timer and power-loss memory make the FH-HB3309 practical for lifetime durability programs that run continuously over days or weeks — without requiring operator attendance during the run or risking test data loss from power interruptions.

Portable Between Test Stations

At approximately 500kg fully loaded, the caster-mounted base allows the machine to be repositioned within a test facility using standard pallet-moving equipment — useful for labs where floor space allocation changes between test programs.

Choosing the Right Scooter Roller Durability Tester

Single Roller vs. Dual Roller — Which Do You Need?

For wheel wear testing only (roller skate wheel compound evaluation, replacement wheel durability), a single-roller bench is sufficient — only one wheel contacts the roller, and the test is measuring wheel surface degradation rather than frame structural response.

For full scooter dynamic durability testing per CNS6263-11 — which requires simultaneous two-wheel loading and obstacle impact — a dual-roller bench is the appropriate configuration. The FH-HB3309 is designed for this application.

Roller Spacing Range vs. Your Vehicle Range

Confirm that the bench's roller spacing adjustment covers your full product range. At 650–1,050mm, the FH-HB3309 covers children's and adult scooter wheelbases but not significantly oversized cargo platforms. If your range includes very long-wheelbase products, verify spacing before ordering.

Obstacle Block Specification

CNS6263-11 specifies 5mm obstacle height. Some machines use different obstacle heights or non-standard obstacle geometries. Confirm that the obstacle specification of any machine considered matches the standard requirement — the height is not arbitrary; it represents the test-defined reference obstacle that was calibrated against field failure data.

Timer Memory for Long Runs

For any test program running longer than a single working shift (8+ hours), power-loss memory on the timer is essential. Verify this feature is present — not all machines on the market include it.

Real-World Application Scenarios

A scooter OEM exporting to Taiwan ran CNS6263-11 dynamic durability tests on its full adult scooter range using the FH-HB3309, running the standard obstacle test sequence with both 5mm impact blocks active. One model's folding mechanism showed audible loosening at 60% of the required cycle count — catching a latch spring pre-load deficiency before the certification submission and avoiding a failed test.

A children's scooter manufacturer used the dual-roller setup at 650mm spacing (matching the narrow wheelbase of its 12-inch wheel models) to run accelerated life testing — running three units simultaneously in parallel across three machines — generating comparative fatigue life data across deck materials (aluminum alloy vs. steel) within a single week.

An inline skate frame producer used the obstacle impact mode to evaluate a new extruded aluminum frame profile against the previous cast design, running both through the same 72-hour obstacle impact sequence under 100kg load and comparing post-test frame deflection measurements — the extruded profile showed 40% less permanent deformation.

FAQs for the FH-HB3309

What is the difference between the FH-HB3309 and a single-roller scooter tester?

The FH-HB3309 uses two rollers running simultaneously, placing both wheels of the scooter on rollers at the same time. This produces the simultaneous front-and-rear-wheel loading that replicates real riding conditions for frame fatigue and folding mechanism endurance. Single-roller benches contact only one wheel, which is appropriate for wheel wear testing but not for full scooter structural durability testing.

Why are there two obstacle blocks per roller?

Two blocks per roller doubles the obstacle impact frequency at a given roller speed — reducing the test time required to accumulate a given number of obstacle impacts, and ensuring that both wheel positions encounter obstacles at the same frequency throughout the run.

What does the power-loss memory function do?

If power is interrupted during a test run, the timer retains the elapsed time count. When power is restored, the timer resumes from the saved count rather than resetting to zero — protecting the test data from long multi-day runs that would be difficult to restart.

Can it test electric scooters under their own motor power?

Yes. The electric scooter is placed on the rollers and operates under its own motor. The rollers provide rolling resistance; the machine monitors speed and cumulative mileage in real time. This configuration supports range testing under standardized indoor conditions.

What roller spacing range does it cover?

650mm to 1,050mm — covering children's scooters (typically 450–600mm wheelbase in the 12–14 inch wheel range, accommodated at the lower end of the range) through adult kick scooters and e-scooters (typically 700–900mm wheelbase).

Is the machine portable?

Yes. Four heavy-duty caster wheels are mounted at the base of the 500kg machine, allowing repositioning within a facility using pallet jack or similar equipment without disassembly.

How many obstacle impacts occur per hour at standard test speed?

The obstacle count per hour depends on roller speed and roller circumference. At a nominal roller surface speed and with 2 obstacle blocks per roller, the impact frequency is logged and displayed in real time on the touchscreen — operators can read the obstacle count rate directly from the display at any point during the run.
