How to assemble a caterpillar electric bike with your own hands from improvised means

Hello friends!

The means at hand are different, and depend on your type of activity and the desire to create something new. But if there are several key components in stock for building an electric vehicle, why not let your imagination run wild?

British enthusiast John Dingley, trained as a physician but passionate about building self-balancing vehicles, constructed an electric tracked track in his workshop using readily available tools.

When assembling, he used three go-kart wheels suspended from a square steel tube frame. A large driven gear is screwed on the rear wheel, and a small 11 teeth on the engine axis.

The chain tensioning system is the same as used for a car generator, where the engine is tilted forward and locked in the desired position.

Welding of the frame and structural elements was carried out using a budget MIG welding machine.

For the axles for the wheels, John used three pieces of pipe with a diameter of 30 mm, and each of the six bearings is fixed to the frame with a bracket and bolts.

Due to the fact that ready-made tracks for a project of this level are quite expensive, the author used a used tire, cutting out the inner part with metal scissors.

The track tensioning system is similar to that used on motorcycles — the wheel is shifted back by rotating the bolts, one on each side, after which it is finally fixed.

The 500W motor from the golf car is controlled by a Dimension Engineering Syren 50 controller, and the power source is a Chinese 24V 10Ah lithium-ion battery.

John admits that the existing battery is not enough, and the charge lasts for a fairly short time, so he plans to eventually replace it with a more capacious one.

Also, in terms of improvements, to improve the steering system, which is actually absent in this version, and the monotrack drives only in a straight line, which is why it got the name «Vector».

One of the solutions the author sees is the modification of the design in such a way that the device self-balances on a smaller contact patch, for example, on the middle or rear wheel.

After watching the video, it becomes clear that the power of the device is not enough to climb even small slides, and at temperatures close to zero, or negative, when the rubber of the tire becomes hard, it probably will not be able to move.

In any case, the design is quite funny and will surely inspire any enthusiast to create similar, but already improved products.
