I want to make my bike electric, how can I do that? Sites would be great, pictures would also be awesome. Anything helps! Thanks!

Answer
I would suggest the excellent engineering text on the subject:
Electric Bicycles, A Guide to Design and Use - Morchin & Oman 2006

It covers the trade-offs between brush and brushless motors and has good graphs for determining the torque-speed characteristic based on the output of the motor.

Best conversion is probably to just buy a good hub motor from a place like ebikes and then consider how you will power it and if you want only an assist when pedaling or an all-electric option. If you have access to a simulation program like PSIM Simulation for power electronics and motor control that can take a lot of guess work out of the various non-linearities involved with the contol of motors especially if you are going to design your own electronics and do your own boards.

What is the most reliable, cost effective, electric bike on the market today?

I really like the Schwinn electric bikes (Continental etc), but I was wondering if someone knew of a cheaper alternative. I don't think I want the SLA battery packs. I would like a smaller and lighter alternative and have a decent range (20 miles or more). I would even consider doing a bike conversion if I could have newer lighter equipment

Answer
Try just a regular bike. Electric bikes are harder to transport, maintain, and still cost money to operate. If you get into shape they aren't much faster than a regular bicycle.
