Small, foldable full-extra electric bike - DYU A5 - removable battery, alarm, disc brake

DYU sent a small but well-equipped bike for testing. Since both the frame and the steering wheel can be folded, it can even fit in the trunk of a small car. It also has an alarm, disc brakes and brake lights. The battery, which can be removed with one movement, can thus be conveniently charged. In the video, I'll show you what it's like, and at the end I'll tell you what I think it's good for and whether it's worth the price.
