I appreciate the comments! First – regarding the handlebars – I really have only started thinkin about them. I don’t intend to permanently attach them to the spring – the idea is that they are adjustable, where the handles can be in position here which is more of an agile position, they can move further down bringing his hands down and more extended/elbows locked into a power/speed position, or go up into a cruising position. I will have them attached to the front end, not the body frame eventually. The overall steering design is significantly different on this bike – turning requires a heavy lean which lower one front wheel and raises the other.
I do think I need to add another support beam – the engine itself is an interesting challenge. I actually planned on mounting it above the rear wheel to make room for some technology that goes in the middle body. This is at least one thing I am considering. That may get too bulky back there and I ll go back to the traditional engine under body design. It is a concept of high-tech nature, in a CG world, so traditional physics are only valid so long as they help the overall bike look cool. This is why art/animation is fun. Its my universe, I can obey what laws I feel like at the time.
