How to legally use electric bikes in Ukraine?

Question

Do it yourself

I apologize in advance for some distance from the subject of the resource.
As an excuse, a little preface.
Having found an article on Habré about creating an electric bike habrahabr.ru/post/192218 , I wanted to digress from software engineering and also make such a miracle with my own hands. I live in Kyiv. But I found that, according to our laws, the use of such a device is fraught with fines and a bunch of bureaucratic problems.
As already discussed, a two-wheeled bicycle with an electric motor up to 4 kW completely falls under the classification of a moped with all the consequences (rights, registration ...). Is it possible to use a tricycle (pedicshaw or cycle trike) with an electric motor up to 3 kW without a license and registration? With three wheels, this is no longer a moped and will not even fall under a mechanical vehicle. Most likely, this tool can only be attributed to self-propelled or can be classified as a trike, but I did not find a clearly defined definition of either one or the other in the traffic rules.
If this is a trike, you need rights and registration, but what does the traffic rules say for self-propelled guns?
The second question concerns where you can move on this. As far as I understand, vehicles cannot move on the sidewalk, except for wheelchairs and supervised children on bicycles, and they will most likely not be allowed on public roads either.
And finally, the issue of registration. Google finds a few descriptions of the process for trikes and other self-propelled guns with internal combustion engines, but so far nothing sensible has been found about electric motors. Do I need to register and where do I need to apply?

Answer 1

I saw comrades boldly dissecting on electric bicycles around the city. Since it does not look much different from a bicycle, I do not think that there will be any problems until the valiant guards cut through and begin to purposefully catch the devices and their owners.
It seems to me that it is easier to get off with a hypothetical fine (which may never be) than to register an unknown DAI device.
Yes, regarding where you can move. You can move on public roads, as close to the curb as possible if there are no bike paths nearby. This is if you move around disguised as a bicycle. And even if not, then there is a general definition of vehicles, under which your device falls.

Answer 2

Easy to use - take and go. I think it is unlikely that your engine will even come close to the power limit specified in the law, a 3kW engine is a heavy canoe, casting doubt on the whole idea with its mass.
Yes, it is forbidden to drive on the sidewalks, but I have never seen anyone being fined just for this. If you were driving on the sidewalk and drove into a pedestrian, then yes, they will issue a fine to the heap.
Therefore, for bicycles, the rules are actually 3:
1) Ride where your conscience allows you
2) Do not poke your head into the city center unnecessarily
3) Avoid busy roads
