1873 Monocycle/Monowheel Replica

Bicycle history has left us with a big range of rare and varied vehicles, especially in the last quarter of the 19th century. For many inventors, the idea of reducing the bicycle to an unique wheel could be very attractive. The first monocycles were constructed very similar to those that we see in circus attractions. The driver must be a born acrobat to be able to dominate the longitudinal and lateral balance. A more unstable vehicle is practically inconceivable. Due to this problem they invented the monocycle with interior rider.We cannot deny that then it was solved the problem of the longitudinal balance, since the gravit center of the system was kept below the center of the wheel.

After much dedication compiling information from books and documentation of epoch of the 19th century, creating a personal budget, and many long hours I got a base of knowledge to make this faithful replication of this unique monocycle for it’s functionality and elegance.

All the pieces that compose this original way of transport have been realized by hand, recreating and improving, whenever budgeting made it possible, all details. Steel and bronze has benn confrontted, been now more attractive. The toothed wheel was dealed before in Oak’s wood as model for the bronze smelting. Later the mechanization work were carried out, polished and protection. The unions and assemblies of the system have been realized by screws(heads and square nuts) and by crushing clinches, skill very used in the 19th century. The outside consists in two hoops, 188 centimeters, lodges a bearing surface in rubber. The inside has got 238 pins, clinched on, which transfer the movement of the pine kernel. It has got a frame on which go three wheels (two guides and motive one). It carries on throught the low part by an skate, preventing then of fallen down ahead. The adjustable saddle is screwed to the mechanism of dulling by cross-bow molded and submitted to a thermal treatment in forge to obtain the suitable alasticity. The tips mounted for friction and rubbing draft in the pieces, are turned in bronze and outolubricated to guarantee smoothness and to avoid wear. Used matertials: Steel-cool (with different alloys and hardness depending on the fatigue of work and wear to the solid alloy bronze, 43mm rubber cord torico, medium hardness, Oak wood, leather, brass. Metals are polished and covered with colorless protection, not using paintings, because they hide and mask the artesal finished of the pieces.

12The driving and the managing of the monocycle is an unique experience. The gravit, centrifuges and inertia forces are basic for it??s funcionality. Changing the weight of the body laterally the monocycle inclines, allowing us the direction.

Nowadays it is an ethnographic museum.
