Old people humorously recall fun rides down snowy slopes on primitive sleds — bowl-shaped rounds made from frozen wet hay in old sieves. Or noisy descents “in a small heap” on ordinary sleds, from which the shafts had been removed beforehand… And today, commerce offers a wide selection of various sleds for this — both Read more…
Before starting to build the micromotorcycle, I spent a long time drawing various layout options, trying to anticipate on paper all possible errors and miscalculations that could arise during the work. Looking ahead, it should be noted that development on paper is one thing, and manufacturing is quite another. Many “rough spots” appeared even during Read more…
In a homestead or dacha farm, even a small one, any mechanized cargo vehicle is a great help. It saves both time and effort. Of course, when it’s simple and reliable. It’s desirable that the machine be small in size for maneuverability and have sufficient power (even at the expense of speed). Its cross-country ability Read more…
Before proceeding to describe the snowmobile “Turtle-2”, I’ll tell you about the history of its creation. This happened thanks to an all-terrain vehicle — a predecessor with the same name, only with the index “1”. That one was a two-wheeled machine on low-pressure pneumatic tires with a D-8 engine with a power of 1.2 hp. Read more…
Once an old friend Igor came to me with an unsolvable (as he said) problem. After the demarcation of the common plot of a four-apartment house where he lives, it was necessary to make and install sliding gates with a six-meter span and an integrated gate. After calling all local and regional companies, he was Read more…
Having been engaged for a long time in the creation and operation of velomobiles (was a multiple prize winner at the All-Union bicycle festival in Šiauliai), I became convinced of their insufficient practicality. The large dimensions of a velomobile exclude the possibility of storing it in an apartment. Known folding designs are complex to manufacture Read more…
From the history of automotive engineering, it is known that the first automobile was K. Benz’s three-wheeled carriage. Later, with the increase in speeds, it was replaced by a four-wheeled vehicle, as more stable in turns. However, designers did not abandon the desire to create a three-wheeled chassis of the same stability. It is structurally Read more…
For my moped, I chose a folding bicycle “Desna-2” model B-849 with reduced wheels (20 X 1.75). To install a motor on it, I made some modifications. I reinforced the frame: I welded an L-shaped tube between the steering column and the backbone beam. I had to spring the front fork with two springs to Read more…
Of all types of sledding sports, bobsledding was the first to gain international recognition — steerable sleds for several passengers. It appeared on ice tracks at the end of the 19th century. Russian athletes rode bobsleds as early as 1910—1912, mastering the slopes of Vorobyovy Gory. Since the first Winter Olympic Games in 1924 in Read more…
…A young driver sits on a miniature, elegantly designed scooter and starts moving. There’s no familiar crackling sound, no annoying smoke. What’s the matter? Looking more closely, we discover that this scooter has an electric motor installed instead of the usual internal combustion engine. The scooter is electric! We admit that such machines are not Read more…
