I wish you had made a new account so you could post this with 1 post count :p. Don't get me wrong, it's actually cool though. But I feel I've seen a similar thing once or twice and people are just wimpy ass creatures or weak-ass creatures (At least in terms of being able to fly). There are some ways to do it, just not very fast.
Edit: i see. If i understand it, I guess the idea is to pedal on the ground, but use the motor in the air? I don't know how i feel about this. It does make me think of a paraglider+ mountain bike combo, and if the mountain bike was super light and integrated with a harness that could be cool for faster landing. I just don't know if it's worth it.
New to endless-sphere? Notice a lot of signatures recommending Ebike.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.
My hat off a thousand times to the green people that effectively run this forum. The ES Mods are superb.
