XYZ SPACEFRAME VEHICLES




XYZ CARGO TRIKE,, 2013



Introduction:

XYZ SPACEFRAME VEHICLES enables persons to build their own vehicles for transporting persons or goods. XYZ SPACEFRAME VEHICLES is based on a low cost, light weight, highly durable construction requiring only simple hand-held, non specialized tools to produce. With XYZ SPACEFRAME VEHICLES, N55 offers a new alternative to mass produced traditional cycle products, often made from low grade materials and not made to last or being repaired.
The designs of XYZ SPACEFRAME VEHICLES including any new construction principle used in the system and the XYZ construction and connection principle are Open Source provided under the rules of Creative Commons as specified here. ( Noncommercial — You may not use this work for commercial purposes. Any use of the works must include proper credits to N55 and collaborator Till Wolfer and a link to www.N55.dk. ). The construction drawings for the XYZ ONESEATER can be downloaded for free here. The XYZ TWOSEATER can easily be build by prolonging the frame for the XYZ ONESEATER..




XYZ ONESEATER; ZYZ EWOSEATER and XYZ CARGO TRIKE prototype, 2012



The XYZ CARGO TRIKE and the XYZ CARGO BIKE has been developed as enviromentally and socially sustainable products for sale and the construction drawings are not available. Persons are of course still allowed to copy these models for non commercial use. We also sell kits and we make workshops to teach persons how to build their own XYZ SPACEFRAME VEHICLES. The earnings from the sale of the XYZ CARGO´s are used to finance the further development of the XYZ SPACEFRAME VEHICLES. The XYZ CARGO´s can be purchased by mailing N55: n55@n55.dk. N55 encourage persons developing new XYZ SPACEFRAME VEHICLES to mail it to n55@n55.dk for publishing.

XYZ CARGO TRIKE with motor, 2013






Construction:

XYZ SPACEFRAME VEHICLES has been developed by N55 in Collaboration with Till Wolfer and is based on XYZ NODES by N55. The frame consists of weather resistant, lightweight, standard aluminum tubes. Unlike the singular load-bearing tube seen in traditional bike structures, the main structure is an orthogonal spaceframe of standard aluminum tubes. A series of tubes of varying lengths are produced, holes are drilled and the frame is assembled using stainless steel bolts, washers and nuts. The assembling requires no welding process. Exposed ends of the tubes are capped with a standard PE plug to avoid sharp ends and to prevent dirt from accumulating inside the tubing. The construction makes it possible to place gear wheels and chains within the frame, away from the users. Instead of using ball bearings for steering parts plastic washers can be used. Whenever needed the tubes are reinforced by inserting POM or PE plugs to prevent the tubes from collapsing. All other mechanical parts, bicycle wheels etc. are standard parts that can be acquired all over the world.










XYZ CARGO BIKE, 2014


Background:

Public spaces in our cities are dominated by dangerously fast, heavy, noisy and polluting cars. The majority of cars are used for transporting one or two persons. The constantly increasing number of cars cause traffic jams and make them inefficient and slow as a means of getting from one point to another in the city. Most cars are using fossil fuels, hereby destroying the environment on our planet with co2 emissions. Our children and we move around in the city constantly risking our lives. The car industry, a large concentration of power with close connections to politicians and decision makers, are now trying to convince us that electrically powered standard cars are the answer to the traffic problems in the world. But the pollution is just moved elsewhere and electrical cars are just as dangerous to persons as traditional cars. Moving 100 or 200 kg's of body weight using a machine that weighs 1000 kg or more is just plain stupid and must be unacceptable from any sane societal point of view. Cars make sense for long distance transport and in rural districts. But in the cities, they are a leftover from less democratic and more brutal times. Before the cars invaded our public space, things and people where transported not only using horsepower, but also a variety of push- carts and large cargo bicycles. Its possible to do that again. Especially combined with intelligent public transportation. Persons could get their daily exercise in a productive way instead of mindless training in time and power consuming fitness centers. N55 proposes that persons reclaim the streets and use them for non polluting, safe, light-weight transport and pedestrians. This would free up large quantities of public space which could be used for cultural purposes, growing food, micro businesses etc. Wide bicycle-lanes should be established to allow for a great diversity in human or small semi-electrical powered vehicles to emerge. There is a tendency that the industry and hereby large concentrations of power prevent us from producing things ourselves. They attempt to gain a monopoly over the delivery of things needed for our everyday lives. There is already an enormous difference in the prices the industry pays for raw materials compared to what an individual person must pay. Because they have an interest in selling as much as possible, the industry provides low quality products that breaks down fast and are being disposed of. Its necessary that persons takes back the control of production of anything from housing to vehicles, make themselves able to repair and produce things by understanding and mastering everyday life technologies. XYZ SPACEFRAME VEHICLES can be seen as an attempt to encourage such behavior.

Environmental impact:

Substituting cars with human powered vehicles would obviously have a vast impact on the worlds CO2 pollution. To produce aluminum requires large amounts of energy and it's production is therefore often situated in close to renewable energy sources, such as hydro-power. However, because of it's low melting point, recycling and remelting aluminum requires much less energy than recycling most other metals. Aluminum is the third most common mineral on Earth and roughly half as strong as steel but weighs a third. So Aluminum has a better weight/ strenght ratio than steel. Because of its unique ability to oxidize fast, it protects its own surface with aluminum oxide and is therefore highly weather-resistant. If the correct alloy is used, no surface treatment involving poisonous compounds is needed.











Models:

Currently we have developed the following models:

All models can be equipped with a 250 W electrical motor.

Maintenaince:

Spare parts are cheap and easy to produce. This eases the repair and maintenance of the XYZ SPACEFRAME VEHICLES. Moving parts must be kept clean and grease applied on a regular basis.If the surface of the aluminum gets a dull look it can be polished using toothpaste.










Extensions:

Because of the modular nature of the XYZ SPACEFRAME VEHICLES system, its easy to customize. A cover or a body to improve the wind resistance and protect from weather condition can be applied.
Standard electrical hub motors can be applied. This makes sense in particular when used on long distances, two seaters or for Cargo versions. Caravan trailers can be developed to allow mobile living.
Cargo versions with kitchens etc could be developed for micro businesses. Small XYZ SPACEFRAME VEHICLE factories could be established in local communities to encourage the use of non fossil fueled vehicles
