So, Now we have a complete bike... not exactly polished or finished or in any way complete, but at least rideable, and suitable for initial testing.
Ben & I added the head bubble last night, so now we can see out whilst riding. The view is a bit like a Ferrari... so I'm told... lots of bonnet & a long view down the road.
Here is the drive system. 2 separate chains drive the front wheel. The one from the pedals runs one of 5 gears on the frame, and another from there runs down to the wheel, single speed. The large 8 speed cog on the frame is known as a mid drive, and allows us to generate huge gears without a massive front chainwheel. In it's biggest gear, one turn of the pedals makes the wheel turn 10 times! Or, in other words, at 100rpm at the pedals, the bike will be rolling along at a lazy 94kmh!
