I have been kicking around the idea of building an e-bike for quite some time now, and i've been doing some heavy research over the past few days on this forum (best i've been to and why I am asking here) and others.
I would like to start out by saying that I live in Florida, and it is pretty much all flat terrain with virtually no hills at all. I am looking for a better way to go around town, because gas is just getting to be too much, and I would love to have an alternate vehicle that I can use which uses none. At the moment, I don't even own a bicycle, because trying to bike around is impractical for so many reasons in my area, such as distance (for normal daily use it would need to go at a bare minimum, 12-14 miles per charge), and the heat is too bad if you are planning on biking to work without electric assist.
First of all, I would like to state that I have all sorts of tools at my disposal (welder, plasma cutter, etc...), and if any parts need to be fabricated it would be possible. This is all completely new to me, and I really could use some help with all of this.
I really look forward to getting some feedback, you have no idea how appreciated it would be!
P.S. I would really like to try and keep the price tag under $1,000 USD if at all possible, since part time jobs while going to school aren't all that lucrative.

- From what i've read over the past few days, it seems like the Dewalt 36 volt battery pack is a good choice for energy storage, but I would like to tear the packs apart and make my own to avoid using the bms that comes with the pack, that limits the current. However, I am very unsure on how to go about that, and what I would need to do about an LVC. I have read all the stickies on the batteries, but I am still unsure. Could someone who has done it explain what is needed? And if there any better options I would like to know.
- I also need to get some information on charging the battery pack once completed. I've seen a setup with many individual cell chargers wired together (not sure how...) feeding into a pack to charge the cells ensuring each cell is charged to it's maximum potential. I do not know if this is the only way to really go about it, or other options that may be available.
- Next thing I need is the motor. I have no idea what type of design I want to go with. I don't really like the look of hub based designs, but they seem to be the easiest route. If there are any other paths I could take with the motor that are just as efficient (or more so), please let me know!
- I'll also need to know what speed controller will be able to be used with what ever motor and battery combo I end up choosing.
