With a carriage (outboard) motor - such an engine has a place in the pedal carriage, and the battery is located at the bottom of the frame. The energy is transferred through the chain to the bike’s rear sprocket. With the help of the speed switch, you can control the load yourself when pedaling. The power of such a power unit is from 400 to 1600 W, and the maximum speed is 120 km / h. Such a motor will provide good rolling, dynamism and controllability. The intensive work of the power unit will not last long, it wears out quickly and needs to be replaced.

The situation was changed by a technological breakthrough, but already in the West. In 1989, the European Michael Kutter (Michael Kutter) developed a pedal assist system. The sensor of the system responded to the speed of the pedals and automatically turned on the motor-wheel of the electric bike at the start of rotation. This technology is also used in modern electric bikes.

Then, in 1989, another innovation arose - Sanyo Enacle became the first bicycle with an electric drive and a nickel-cadmium battery. The technology has been developed with the release of the Sinclair Zike. It was a super-compact e-bike, but it "failed" because of a contractor who could not keep up with the planned production volume: https://digitalflip.co/gadgets/Best_electric_bike_under_2000/. And in 1991, Sony and Asahi Kasei released the first commercial lithium-ion battery. It was smaller and lighter than other power sources.
