It's looking like a total expensive failure. That battery pack is rated for <20A max continuous. You'll probably want one capable of 100A minimum. The tc 4080 on 72V will top out ~40 mph. I do better than that will my cheap 1000W motor.
 
That battery will be a problem for a high powered setup. It has a max continuous discharge of just under 1C. it's great for a low powered motor, but you'll kill it swiftly with a high powered bike. 29E cells are not high output cells
"Nominal Capacity: 2,850mAh (0.2C, 2.50V discharge) Max. Discharge Current: 2,750mAh (continuous discharge), 8250mAh (not for continuous discharge) " Source
Since LAebikes wants to try to claim this as a 60A continuous battery, I'd be reluctant to trust them any further.

EM3ev has the same frame.

The motor depends on what you want to do with the bike. If you're looking for hole shots up to 50mph, then the MXUS would be a good cheaper motor, but both the MXUS and the TC4080 need 100 volts to reach 50mph. If you plan to cruse at 50mph, then I think you're building the wrong kind of bike. The TC4080 will overheat in 16 minutes on flat ground at 50MPH, and that's just the start of the problems.

Hello

Are you clear on what the bike will be used for and how often? Might be some functionality and user friendlyness to gain by going thropugh this if you havent already.
Do you plan to put the parts on a std bike or build something custom? How are you setting up charging, storing etc?

Hello,

Bike purposes are for daily transport, mostly from work to school and about, but it won't be substituting the majority of my vehicles duties. I'd like to take it to a track once I get a reliable machine up and running.

I was planning on building it from the frame out, doing as much as possible myself and locating others to assist in anything else.

Charging will just be done at home through a standard 3 pin outlet, unless a better option is available. Most likely will pick up a 72v 3 & 5amp charger (Satiator has a popular one). I'll be storing/charging in a small, empty outdoor shed. It's free from any hazards and I'll probably build some form of charging station.

Excellent, thanks so much. Taking that TC4080 off the considerations list and looking at a QS or MXUS. I'll keep looking around. It seems as though the proper battery to utilize as much interior frame real estate is the hardest part to source at the moment and I might have to construct it myself. I listed those specifications largely because I didn't want to limit myself too much. Allocating resources to squeezing out cruising speeds past 50mph doesn't seem very viable, and it's obvious that money would be better spent other places. Proper active and passive cooling and ventilation is still being looked into.
 
50mph bike for ~$1K.

Motor kit. $400-$600, depending on how good a deal you can find. MXUS 3000 3T or similar. You need at least a 60A controller.
Battery 10ah 24s 10-20C rc lipo. I bought 2 on sale for $180 each from hobbyking.com.
 
Hello, I work for LA Ebike. we actually run the pack on our bikes.

Yes there was misinformation and confusion over the battery cells in our packs, I took a inside today.

They are actually Samsung SDI ICR-18650-22P cells, and we do run them in our frame paired with the Sabvoton 72V80A (Limited to 60A)
