Logic of Testing
Evoke Motorcycles, as an explorer and leader in the electric motorcycle industry, always puts improving customer experience as a top priority. To achieve the continuity of experience improvement, the never-ending work is R&D and testing. We have adopted a cycle structure that includes constantly absorbing various improvement opinions, proposing several experimental designs, testing and accepting on the road, and combining the supply chain to determine how to stably improve in production.
We collected feedback from customers all over the world with different driving environments and climatic conditions and then dedicated it to the proposal of experimental design.
Experimental designs are always exciting and Evoke Motorcycles' global team of engineers can always come up with interesting designs. We will use creative methods to implement the best designs in the workshop, and then test them on the road.
The importance of testing on the road is self-evident. Safety comes first. Our new ideas must not affect the original safety design, such as interfering with the rearview mirror or the stability of the vehicle when riding. Second, the new changes should be durable enough. Repeated tests can ensure that there will be no disturbing wobbling noise of a part after riding over a speed hump. Of course, the new design must be implemented to improve the pain points of users ultimately. The engineers responsible for testing Evoke Motorcycles are also experienced motorcycle enthusiasts. They will ensure that everything achieves the expected results.

Meet Our Frankenstein Warden
Professional testing requires professional personnel. Because all this requires not only strong professional knowledge, rich experience in debugging hardware or software, and common sense of motorcycle driving, but also agility and decisiveness on the spot when the motorcycle starts losing its balance at thrilling speed. Why not come and chat with one of our best engineers of Evoke Motorcycles?
1. How different it is between designing & testing an aircraft and a motorcycle?
Same and different. In the nutshell, it is like to cook good coffee or hot chocolate - I like both by the way. The natural laws are the same, approach, and features are different.
However, I would not say that the design of a motorcycle is so simple stuff. Many other features come first here. We aim to make new motorcycle models properly working and with some new solutions fast (particularly for electrical bikes), it should be in the cost range, safe, comfortable, and exciting to ride.
2. How many years have you been riding a motorcycle? How many different motorcycles have you ridden?
Well, I bought on saved money my first bike when I was 11 years old. It was a very old Russian bike. I repaired it definitely more time than riding. Frankly speaking, Russia is not the best place for motorcycles, the season is really short. After I moved to Beijing, I have ridden and tested an uncountable amount of motorbikes. Right now, I am confident to ride on anything that has two wheels in our workshop.
3. Do you think testing is important? Why? Of course, testing is important. It is not only about safety and specs. Test ride also highlights the ergonomics and the character of the bike. It helps a lot to speed up the design process.
4. After new ideas are installed on the bike, how many tests need to be done to make sure it’s working? New ideas definitely taking more time, more tests as well. Such as the firmness, durability, performance in peaceful or intense driving, and most importantly, what if someone rides like a nut? We try to cover all the possibilities. However, there is still a risk of whether customers will like it or not.
5. Have you ever encountered any dangerous situation while testing a bike? How did you handle it? So far, I haven't experienced super dangerous situations while testing. Small failures did happen because, in certain test situations, motorcycles are pushed to or even beyond the daily use limit, especially in a pressure test. Once I was testing one of our prototypes, by the way, it would be super nice, the aim was to drain the battery at top speed cruising without an electric limiter and see the bike’s reaction. Around the end of the test, one component got overheat but I had to maintain some speed to cool it down with airflow. I managed to ride back without igniting anything. We do this so you don’t have to experience an emergency.
By the way, there is a Frankenstein bike locked in our basement and you will never see it because it failed the pressure test.

Data logging for electric vehicles offers numerous benefits. Firstly, it enables vehicle owners and enthusiasts to comprehensively analyse and evaluate their vehicle's performance. By recording essential parameters such as engine RPM, speed, throttle position, and braking force, among others, data logging facilitates the identification of areas for improvement, fine-tuning of vehicle settings, and tracking of performance changes over time. Furthermore, data logging serves as a valuable diagnostic and troubleshooting tool, providing crucial information about sensor readings, error codes, and system behaviour during specific events or conditions. This empowers mechanics and vehicle owners to identify problems accurately and make informed decisions regarding repairs or maintenance. For performance enthusiasts, data logging allows customization and optimization of vehicle settings, as continuous monitoring and logging of performance data enable precise fine-tuning of engine parameters, suspension settings, and other components. This approach helps achieve desired performance characteristics while maximizing efficiency. Importantly, data logging contributes to safety by providing insights into driver behaviour and vehicle performance, recording data related to acceleration, braking, speed, and other parameters. This information can be utilized for training purposes, monitoring driving habits, and assessing vehicle performance during critical situations. Thus, data logging proves to be an invaluable tool, offering multifaceted advantages for vehicle owners, enthusiasts, mechanics, and the automotive industry as a whole. When it comes to Evoke Motorcycles, collected data is used for identifying errors and potential areas of improvement in prototypes and other models. If an error or an abnormality comes up in the data, it can be easily noticed and traced to its origin, helping identify the root of the problem. Furthermore, using data brings valuable insights into driver behaviour and its variety. If one behaviour is more prevalent than the other, or there are many, the design or parameters can be manipulated to better suit the driver and make the driving experience much more pleasant and comfortable. In the future, data analytics are planned to be shifted in the hands of AI/ML providing instantaneous criteria and analysis on the go, as the data is being collected. This will fully automate the process and result in much more detailed diagnostics once the AI is sufficiently trained on the past data processes. All of the data is collected and stored within the vehicle, as this surpasses the limitation of servers. If the data is stored within a server in one country, a user in the other might not be able to access it. If the data is stored inside the Evoke motorcycle itself, the user can access it at any point and maintains full control of their own riding data. If there are any issues with the electric motorcycle, or the user would like to understand their riding data better, it can be easily sent to Evoke for review, bypassing any geopolitical limitations that would be otherwise present with the use of servers. The vehicle records up to 10 hours of riding data and is collected every 0.5 seconds. As of 2024, the 120 collected data points make up the five main data pools:

Vehicles, that run with combustion engines or ICEs rely on a jackshaft to efficiently distribute the produced power or simply optimise the conversion of energy to the wheels of the vehicle. ICEs cannot automatically regulate the speed of their rotation. In order to control it, different gears are introduced, to be able to increase and decrease the torque. If the jackshaft is part of a transmission system, it may have multiple gears or pulleys of different sizes attached to it. These gears or pulleys can have different ratios, allowing for torque conversion or speed adjustment. Gear ratio can be calculated via the formula below:

In terms of automotive there may be a handful of principles that determine the overall form and componentry present on a vehicle. Inescapable is physics, aspirational is performance but as another 20th century icon dictated, there's no escaping the bottom line and in manufacturing that means a need to establish and maintain a lean operational footprint.
