I love this stuff (personal electric transportation), and this one looks fantastic.
It costs $2500 (US). Weighs 44 pounds.
Stuff I would make differently...
... aluminum frame instead of steel to reduce the weight
... Delrin ramps in front of the rear wheels, probably just over half way down on the wheel so the rear wheels will not bind on a high obstacle... because the frame might not be low enough and it should be protected anyway
... probably a narrower stance, I would not use the bike for carving
The trike stance is plenty wide to provide balance. The flexible foot stems allow individual suspension (aided by your legs). The front wheel is big (10 inches) but could be much larger to help go over higher obstacles.
What about the "brushless geared hub motor" motor? Does that sound good? Does it at least sound familiar? Any offhand information (or references) about that type of wheel drive would be appreciated. I will do some research.
Thanks.
