Introduction: KP Solowheel Ver.2
Well, after experience with wooden KP solo-wheel, i decide to rebuild it, hoping for better results. As always, material should be cheep but strong enough for such purpose. And also an important approach was drawings with general measurements, to get relation between weight and maneuverability.
One day I spot a Al-ladder on flee market I bought it with a 41 cm bicycle wheel.....few bucks.
Step 1: Assembling, Sawing, Rivets and So On...
Well. according idea an measurements I start to cut, assembling, riveting and after few days. ..prototype was made.
First impression: very light and stiff.
Step 2: Later Improvements...
You can see general look, as how it look in the transport form and seating form. Also same ways how ti get secure biong when the solowheel are streighten.... and so on. For me best is with two U-form on each sides at hinge place....
Step 3: Test on Velebit Mountain 2016
Croatian mountain Velebit is rough, dangerous, an most beautiful but inspired mountain. In winter freezing cold ..in summer frying pan. Two national parks. Bears, fox, wild boar, deer, lynx, buzzard... flowers. bugs, birds. And human. But rare.
Last week I was on Velebit and:
Test show that where is a good path, without big rocks, solowheel fulfill all expectations. 27 kg pack is effortless to pull, instead carry a backpack.
On the rocky path you have to stop, carry contents as a backpack and after to continue. It is not for running. It was made to go slow, stop and stay and rest.
