I built an ebike about three years ago. These links were very helpful to me to get ideas:
http://www.austinev.org/evalbum/ - photo album of electric car, bike, etc. designs. http://groups.yahoo.com/group/power-assi st/ - yahoo group for motor assisted bicycles.
I used a mountain bike, EV warrior motors (dual dc motors with friction drive with the back wheel), a pulse modulated speed control, and deep cycle AGM batteries. The original design is on this page.
http://webpages.charter.net/schiavoneaj/ebike/ I have made a few modifications to the design: 1) I moved the motors further back because they got too hot being so close to my legs, 2) I moved the batteries to each side of the back tire because it was too top heavy, and I made a better speed controller housing.
I can get around 16 mph and a range of 8 - 10 miles with two 12V 17 amp hour batteries (total of 24 V driving the motors).
And contrary to all the fat ass comments, it was fun to build, is fun to ride, and I do get exercise because I pedal in addition to using the motor.
I too have the Hauppauge WinTV Go (Bt848) card in my Linux box. It records video fine, but the audio recorded has a very high pitched whine noise in it that makes it nearly unusable. This high pitched noise is there when just watching TV but it is hardly noticeable; it just really shows up when playing back a recording.
What Hauppauge card do you have (is it stereo)? Is your audio noisy?
