Folding bike nowadays. However, its dimensions even when folded, not too small, and to keep it at home and even more to transport on the bus or tram is not always convenient. I set a goal to develop a convenient folding bike smallest possible folded size. I wanted it to be easily transformed into a suitcase size with the usual “diplomat”. I have to say, this was not achieved, but to construct a two-wheeled machine, which, after transformation to fit in a suitcase or bag with the size 650x450x150 mm, I still did.THE BIKE IN THE SUITCASE

For successful fishing it would be nice to to good gear added luck, but still; as they say, “gotta know”. And if luck is fickle thing, then the place where the fish, I knew.

As soon as the first snow fell, it became clear that the house has no need of such cargo winter vehicle as a sled. Child’s sled for a long time “went” on a well-deserved rest in a pile of scrap metal, and weak they would have to carry the heavy loads.

Fifteen minutes — and the room is free for practice sessions.
Description a three-wheeled tandem, published in the journal (№3, 1979), I liked inherent in it the idea to tandem bike of the usual single, without making major changes to the original design. But the proposed version was not very satisfied: still frame of the second bike had undergone the unwanted interference.

The sled with the motor for the little ones. Before to introduce the following proposed material, I want to remind small note in No. 2 of our journal in 1979 — “Folding sled”. Because the author of the two designs is the same — our reader from Kazan E. Zakharov. Technical creativity pushed his little boy, who every morning had to carry to kindergarten. A regular sled because it’s bulky to travel with changes in transport are not very good, and E. Zakharov builds original furniture, the type of walking cane-chairs, now enjoys great popularity. Folding sled has interested many of our readers who have decided to make the same: it is not only convenient in use but also during storage.
