Bikes: too many of all kinds
Yep, that first kit will work. The controller will work with 24 or 36 volts (some people run them at 48 volts).
The 24volt and 26 volt motor are basically the same (Well the internal gears are a little different, but the electronics are the same). That motor will run fine on 44 volts nominal (12s lipo) and plenty of people run it at 48v. Its really the current where people run into problems. 15amps is good, 17 is max.
My current favorite battery (as of mid 2013) is the Samsung batteries sold at EM3ev. Its probably 60% of the size and weight of LiFePo4, but only has about 1/3 of the recharge cycles. Choose your poison (size-weight vs recycle times).
If you only need 20+ mile range, a 36v10AH is fine. 25 miles, 12AH, 30 miles 15AH. You can extend this by pedaling of course. (I’m doing 24 miles on 10AH)
You can either use the PAS & thumb-brakes or use the throttle, or use both. Whatever your preferred method, it is a good idea to order spares as they are very cheap, and will take a lot of time (and extra shipping $$$) to order them later. Cheap insurance to buy some spares now.
You basically need:
· Throttle (if using PAS as a throttle, you need the brake levers to ensure it cuts off under braking)
