That is absolutely fabulous - and i love your accent too ! I think you have showed what can be done with dedication ,patience and skill which i for one do not have !

 

[sbech]

Thank you, people, I am very glad and happy to see your words, and your forum overall - it is interesting, to know, that such motorized bicycles are built also in US and Canada, Australia!

accent

English is my third foreign language... Hope, I am better, than Google Translate

lens

One of aspects, good for restoration of Russian machinery - that time (50-60-70-ties) a lot of products were standardized in planned economy. For example - very-very similar lenses were used not only on bicycles, but also on different agrimotors, cranes, tractors, and even military machines, just painted green there.

My son studies the Russian language. He was not interested in motorizing a bicycle at all until he saw your D-4.

My son studies the Russian language.

Here is a book about testing and driving the first D4 engines, in 1950-ties. Book in Russian.

... these were totally crazy motorized bicycle riders - drive them across the whole USSR, including desert, bad roads etc., without cellphones, without assistant car and so on. Enthusiasts!

whats the comparison about the original and the re manufactured?

 

[caduceus]

You have done a very nice job restoring that bicycle. I am very impressed with your stencils and decals. Thank you for sharing the pictures.

 

[NunyaBidness]

Very nice work.
Thanks for sharing your build process and the pics.

the comparison about the original and the re manufactured?

Which one?
In case of this V-902 engine - non-original are inside bearings and high voltage plug wire. All other - original parts. Including spark plug itself...

If you are talking about comparison of that one old Russian engine and modern Chinese bicycle engine kits, here is whole thread:

decals

That was a long story... Wanted them quite a lot, but had no example... Then saw similar motorized bicycle being sold, called a seller, and got these pictures:

Then some hours spend with GIMP...

That is municipality council tower in city of Lviv.
