Radius Elite hubless sport bicycle

 

Inspired by the UCI world championship bicycle road racing, I created this hubless concept sports bike. Transmission is a variable planetary gearing. Position of saddle and handlebars can be adjusted to suit rider preference. Just below the saddle a bidon or storage unit can be clicked into the frame. Lighting is placed on both sides of the rim covers - white LEDs at the front, red LEDs at the rear. On the left handlebar an adjustment wheel is placed to dim the lighting. The right grip of the handle bar can be rotated to switch gears without taking the hands off the handlebar. The image was drawn in Affinity Designer. Click the image to see a larger version of it in Google's Lightbox. Turn the mouse wheel to flick between the images (on a desktop computer).

3D printing

3D printing has a great future. The devices are still unaffordable for the average consumer, but as the technique develops it will become within reach of the private people. Larger, complex objects will be printed by specialized companies, but simple constructions will one time soon be printed at home not too far away in the future. As is the case with all consumer goods, the possibility to produce complex objects with 3D printing devices will be increasing rapidly. This will include plastic parts, composite materials, metals (including non-ferro objects). Basically any material needed to produce useful things.
