Built for the Ride. Tested Before It.
Long before the first ride begins, every HITWAY e-bike has already been through a journey of its own.
From the first design concepts and the transition into production to component testing, complete-bike testing and final inspection, each stage plays a role in preparing the bike for everyday riding.
At HITWAY, we believe that testing should do more than confirm that a bike looks finished. It should help us understand how its components and systems perform before the product moves forward.
Before a HITWAY e-bike leaves the factory, it has to pass through more than assembly. It has to go through testing.
Here is a closer look at what happens behind every HITWAY e-bike before the ride begins.
Quality Starts at the Drawing Board
Quality is not something that can simply be added at the end of production. It begins much earlier, when an e-bike is still taking shape through sketches, technical drawings and early design concepts.
During product development, decisions around frame geometry, structure, component positioning and everyday usability gradually transform an initial idea into a complete e-bike.
Each decision has a role to play, because the way individual parts are designed and positioned influences how they eventually work together as a complete system.
Thinking through these details early in the development process also gives the team an opportunity to review ideas, make adjustments and refine the product before it moves further towards production.
A finished e-bike may be what riders eventually see, but its story starts much earlier—with the thinking behind the design.
Good testing finds problems. Good design helps prevent them.
From Design to Production
Once a design moves into production, ideas on paper begin to take physical form.
Frames, wheels, drivetrains, controls and other components gradually come together through the assembly process. At each stage, parts need to be correctly positioned, installed and adjusted so that what was originally defined during development can be translated into the finished bike.
But production is about more than simply putting components together.
As the bike begins to take shape, it also provides opportunities to observe how different parts fit and function together, make necessary adjustments and check the execution of the original design.
Step by step, what began as individual drawings and components becomes a complete HITWAY e-bike.
And as the bike gets closer to completion, the next question becomes increasingly important:
How does it perform?
Putting Our E-Bikes to the Test
A bike can look complete long before the work behind it is finished. That is why testing is an important part of the journey from production to the road.
At HITWAY, different testing equipment is used to examine components and complete e-bikes under controlled conditions. Depending on the component and test stage, these checks can involve repeated mechanical loads, braking operation, riding distance, water exposure, corrosion resistance and material strength.
The purpose is not simply to complete another step in the production process.
Testing helps us identify potential issues, verify function and create opportunities for adjustment before a product moves forward.
WHAT WE FOCUS ON
COMPONENTS · ASSEMBLY · FUNCTION · DURABILITY · COMPLETE BIKE
Testing the Complete E-Bike
One of the most important questions is how the complete e-bike performs once all of its individual components come together.
For this, HITWAY uses an E-Bike Comprehensive Performance Test System to simulate extended riding conditions.
Under the general test procedure, a complete e-bike is tested over:
- 500 km without bump blocks
- 200 km with bump blocks
After testing, the complete bike is checked to confirm that its functions remain normal and that components have not become loose.
This type of testing looks beyond individual components. It gives us an opportunity to examine how the assembled e-bike behaves as a complete system after repeated riding.

Testing the Frame Under Repeated Loads
The frame forms the foundation of an e-bike, so structural durability is an important part of testing.
HITWAY uses a Combined Vertical & Horizontal Frame Fatigue Testing Machine to apply repeated loads to test samples.
Under the specified test procedure, a force of 1,100 N is repeatedly applied for 50,000 cycles.
After the test, the sample is checked for:
- Cracks
- Deformation
The test requirement is that the sample shows no cracks or deformation after the specified cycles.
This repeated-load testing helps us examine how the frame responds to forces that are repeatedly applied over time.
Putting the Front Fork Through Its Paces
The front fork plays an important role in controlling the front wheel and absorbing the demands of different riding surfaces.
To evaluate its structural performance, HITWAY uses a Multi-Function Fatigue Testing Machine.
The specified test applies a fully alternating dynamic load of 600 N to the fork for 150,000 cycles, with a test frequency of no more than 10 Hz.
After testing:
- The fork must not break at any point.
- Permanent displacement of the wheel axle or simulated axle relative to the fork steerer axis must not exceed 45 mm.
Rather than relying only on a visual inspection, this type of fatigue test allows the component to be repeatedly loaded under controlled conditions.
600 N · 150,000 cycles · ≤10 Hz
Testing the Saddle and Seatpost Assembly
The saddle and seatpost are among the components riders interact with constantly. They also experience repeated loading throughout everyday riding.
HITWAY uses a Saddle Fatigue Test Machine to evaluate this area.
During the test, the seatpost is inserted into a simulated frame at its minimum insertion depth, with the simulated frame set at a 73° angle. The saddle is positioned at its rearmost position, and an alternating vertical load is applied at a specified point on the saddle.
- 650 N for city bikes
- 800 N for mountain bikes
The test is repeated for 100,000 cycles.
After testing, the saddle's outer covering and padding must show no detachment or damage, while the saddle frame must have no cracks.
Up to 100,000 cycles · 650–800 N depending on bike type
Testing Brake Controls and Braking Performance
Braking is another area where repeated use matters.
HITWAY uses a Brake Lever & Braking Performance Test Machine to test brake levers and braking-related performance.
For the brake lever fatigue procedure, the lever is secured to the testing machine and operated at 4-second intervals for 50,000 to 100,000 cycles, depending on the requirements specified for the relevant product.
After testing, the brake lever is checked to ensure that its appearance and basic functions remain normal.
This repeated-operation testing is designed to examine how the control responds after being operated many thousands of times.

Testing Materials and Component Strength
Mechanical durability is not only about complete assemblies. Individual materials and components also need to withstand specified loads.
HITWAY uses a Universal Testing Machine for material and component strength testing.
For the bicycle chain test listed in the factory testing standard, the specified breaking force is: ≥ 8,010 N
The referenced standard is GB/T 3579-2006, Bicycle Chains — Technical Requirements and Test Methods.
Testing individual components under controlled loads provides another layer of information before they become part of the finished riding system.
Testing Resistance to Water
An e-bike may encounter rain, splashes and wet riding conditions during everyday use, so water exposure is another part of the testing process.
HITWAY uses a Rain Test Chamber for water-resistance testing.
The spray head sprays water within a 60° range, with a water flow rate of 0.75 L/min, and the test lasts for at least 5 minutes. The spray direction is then adjusted to provide 360° coverage for each relevant area, with a water flow rate of 10 L/min for 5 minutes.
After testing, there must be no harmful water ingress, and the tested functions must remain normal.
For the battery test, the battery is installed on a complete e-bike and exposed to water from all directions at a flow rate of 6 L/min for 6 hours.
After testing, the battery must show no signs of water ingress.
These tests help us examine how relevant components respond when exposed to controlled water conditions.
Testing Resistance to Corrosion
Components may also face moisture and environmental exposure over time.
For corrosion-resistance testing, HITWAY uses a Programmable Salt Spray Test Chamber.
The specified test uses a 5% sodium chloride solution, with the solution adjusted to a neutral pH of 6–7.
The test temperature is 35°C, with a specified salt deposition rate of 1–2 ml/80 cm²·h.
The standard test duration is typically 72 hours, although the actual duration can vary depending on the test sample.
This type of controlled exposure helps evaluate how tested materials and components respond to a corrosive environment.
5% salt solution · 35°C · typically 72 hours
Testing Material Flammability
Certain materials are also subject to flammability testing.
HITWAY uses a Horizontal & Vertical Flammability Test Apparatus for this type of evaluation.
Under the specified test requirements, after the sample is exposed to the flammability test, it should:
- Have no continued burning, with a self-extinguishing time of ≤10 seconds
- Produce no molten droplets that ignite combustible material below
- Show no flame spread into non-exposed areas of the sample
From Individual Components to the Complete Bike
A complete e-bike is more than a frame, a motor and two wheels.
It is a complete system made up of many individual parts, each with its own role to play.
The frame forms the foundation. The drivetrain transfers power through the bike. Wheels connect the bike with the road, while the saddle, controls, brakes and other contact points shape the way riders interact with it every day.
That is why testing does not stop with a single component.
A saddle can be tested separately. A brake lever can be tested through repeated operation. A frame can be subjected to repeated loads. A complete e-bike can then be tested over hundreds of kilometres.
Each test looks at the product from a different perspective.
Components are tested individually. Systems are tested together. The complete bike is tested as a whole.
Together, these layers help create a clearer picture of how an e-bike performs before it reaches the rider.
From Testing to Final Inspection
Testing is not necessarily the final moment before an e-bike leaves the factory.
After production and testing, products still need to go through the final quality-control process.
At HITWAY, the internal requirement is that products must achieve a 95% qualification rate before being released from the factory for shipment.
This threshold forms part of the final quality-control process before products move forward.
It is important because quality is not determined by a single test.
A product can pass an individual component test, but the complete manufacturing process still needs to be considered. Assembly, component condition, function and the overall product all contribute to the final result.
The goal is therefore not simply to have a bike that looks complete.
It is to make sure that the product has passed through the required checks before it begins its journey to the customer.
Test. Check. Refine. Repeat.
The Details Behind Every Ride
Every test has a purpose. Every number represents a standard we use to examine the product more closely.
They represent the time, attention and care that go into refining every part of a HITWAY e-bike—from the frame and fork to the braking system, battery and other key components.
Because every detail matters.
And when all these details come together, they create something that matters even more:
a better riding experience.
Made for the World Beyond the Workshop
Design studios, production lines and testing environments are all important parts of the story—but they all lead to the same destination: the road.
Every detail we examine, every component we test and every improvement we make is ultimately intended to create a more reliable, comfortable and enjoyable experience for the people who ride HITWAY e-bikes.
From the first sketches to the finished product, the process is built around one simple idea:
Keep refining the details that make the ride better.
The frame, motor, battery, brakes, fork and every other component are not developed in isolation. They come together as one complete riding system, carefully tested and refined before the bike is ready for the road.
Because a great riding experience is built from many small details working together.
And that is what drives the work behind every HITWAY e-bike.
Every test. Every adjustment. Every detail.
All for a better ride.
So you can focus on the journey ahead.
FAQ
What should I look for in e-bike quality?
