The speaker in the video discusses the concept of a four-wheel motor scooter, comparing it to traditional skateboarding. He starts by researching the best skateboards and their components, leading him to expensive models with semi-hollow wheels and carbon fiber boards. However, he finds these models too expensive and difficult to master, especially for a beginner.
He then talks about the evolution of skateboarding, with the introduction of independent suspension on each wheel, which improved the turning radius and stability. This led him to compare skateboarding to scooters, where he found scooters more practical and fun, with better direction and handlebars.
The speaker then shares his own attempt to build a four-wheel motor scooter. He started with a steel chassis with directional front wheels and rear wheels that rotate when tilting the board. He modified a two-stroke lawnmower engine, added paint and screws, and used a second-hand scooter as a base.
However, the speaker faced challenges with the starting process, the noise and smoke emitted by the engine, and the attention it drew. Therefore, he decided to create an electric version.
To do this, he bought a scooter with in-wheel motors of 1,200 watts each and a removable battery. After testing and dismantling the scooter, he faced challenges with the wheels, the battery, and the controller. He had to make several modifications, including cutting and shaping a piece of tube, making the axle longer, and creating a wooden box for the battery and controller.
Finally, he connected the motor cables, tested the scooter, and found it to be fast, practical, and fun. He concludes by suggesting that the four-wheel motor scooter could be the future of scooters.
Here are the key facts extracted from the text:
1. The text is a transcript of a video about how to make a four-wheel motor scooter.
2. The video shows the process of modifying a children's scooter with a steel chassis, directional front wheels and rear wheels that rotate when tilting the board.
3. The video compares different types of skates and scooters and explains why the four-wheel motor scooter is more practical, fun and stable than traditional ones.
4. The video also shows the challenges and solutions of adapting a skate with in-wheel motors and a removable battery to the scooter chassis.
5. The video demonstrates that the four-wheel motor scooter can reach 45 km/h, has a range of 30 to 80 km, and can skid and do wheelies.
