This project is my approach to a bicycle concept, a two wheeled handbike. The handbike was designed originally for people with mobility constraints and disabled, so it has 3 wheels, because the users can not get equilibrium. The design proposed in this project, is a bicycle propelled by hands power, to exercise arms muscles, but with the good feeling of to tilt the body to make turns, justifying the decision of I choose two wheels.
To execute the project, it was reused several bicycle parts spreads around my house, like two frames, size 19, a front suspension, 20" wheels shared from another bike, and many other things that I found, and I neither knew I had. I still build the prototype, and sending the progress to Hackaday IO, when the experimental phase be finished, I will paint the whole bike, it going to be pretty.
More details can be found in my blog, at this link: pedaldamata.blogspot.com, I write much more there, but it is only in portuguese, if you are here, you already are a hacker, and to use Google Translate is a easy task for you.

How well does it work?
I am wondering if the weight distribution and high centre of gravity will work well with the front wheel drive. Especially when going up hill. I would probably try to move the seat as close to the steering tube as possible and add a foot rest in front of the wheel.
Also the force from the chain will compress the front suspension which will swallow a lot of the power. May be remove the springs from the fork and lock it in place.
