As promised, here is some video footage of the Dagne proof-of-concept prototype. We decided to share some of the early (unedited) videos we took of the prototype so you can get some perspective on our development process, and a clear sense of who we are and where we’re coming from.

Each of the videos is posted on YouTube. Be sure to click “watch in high quality” under the video image to get good resolution. Please come back HERE to our Blog to post your comments. We hope you enjoy watching these!

Video Clip #1 – Dagne’s First Test Drive: This is our first powered test drive out of Eric’s garage where we built the prototype. At this point, the steering and braking were still a bit twitchy, and we were controlling FWD/REV with a foot switch (ironically). The lean was mechanically locked upright, so turning caused Dagne to lean to the outside in a turn (not so comfortable). The top speed here was about 2.3 mph 🙂

Video Clip #2 – Dagne’s Second Test Drive: Note: the traction battery didn’t actually die – we later realized that a disable feature in the motor controller had been inadvertently triggered.

Video Clip #3 – Dagne’s First Lean: This was the first time Dagne’s lean was actively controlled. At the low speeds we were limited to in Eric’s street however, the lean was pretty subtle. By this time the braking and steering were quite smooth due to some mechanical and software improvements we had made since the first test drives.

Video Clip #4 – Dagne Intro and Carving: This is our first “Hello World” video, with a little tour of the prototype by it’s creators and a short test drive with modest carving. We will need to build the next prototype (the alpha prototype) before we drive much faster than what you see here, due to some re-engineering we need to do to the lean/steer mechanism to make it more stable, as well as using a proper battery pack that can support higher speeeds.
