Yeah, we started the bike project a lot of time ago, but then because a huge lack of time, and some hardware failures, it was shut down.
Then, a few weeks ago, we've re-started the project almost from scratch; this time the developement is going much faster than before, so... this is it, this time we'll release a full-working bike, no matter what
Please note that this topic is intended to be focused only on the engine; after the completition of the running gear (right now we're debugging physics and scripts) we'll create another topic for it, so be patient
PS: thanks to KeeJay for having emphasized download link, I'll add it in my signature too
