Picture 1 show the bike as it is now.
Picture 2 shows that the rear bike wheel was welded to the car tyre, this was put on so that the bike could be pedalled.
Picture 3 shows a basic chain tensioner welded onto the frame. This was because the extended chain I fabricated was slightly long.
Picture 4 shows pedal bars, These steel rods were welded on because we didn't have any real pedals.
Picture 5 shows the scooter front wheel. This picture also serves the purpose of how different in size the original wheel was to this one.
Picture 6 shows the frame fabricated to hole the car tyre. I used 30x10mm flat bar I found in my garage. The bolt you can see is the original axle from the bike rear wheel which is welded to the car wheel on the other side.
Picture 7 shows where I welded the two wheels together, These are only small tack welds, but hold it sufficiantly.
I had to join two parts of chain together to span the longer distance between the sprockets, and have since found that gears might have been a better choice because it is very hard to pedal going up even a slight gradient. Pedalling on the flat os still pretty hard but acheivable. Going downhill is the best and more fun.
I actually made this project before I had joined Instructables and therefore don't have any construction pictures, but I have tried to explain each procedure with the finished product pictures above. It didn't cost me anything because I had all the parts in my garage and it took me about 3 hours to finish.
