Hi Kev.
If you don't have steep hills in the "flatlands" of Kansas, you may not need the high power of the Magic Pie, especially when it is inside a small 16" wheel with very little weight pushing down upon it.
There would also be a fair amount of residual drag from a Magic Pie 5 in such a small wheel that would probably be very noticeable at speeds above 7mph with a small 16" wheel.
A Smart Pie might be a more sensible option, unless you really do need a large amount of hill climbing power and don't intend to assist the motor with some pedal power.
Here are some rough figures calculated from the performance data for the following motors:
The 48V Smart Pie should produce ~20lbs of thrust @ 13mph 692W @ 74.9% efficiency.
~42lbs of thrust @ 1.5mph 717W @ 17.4% efficiency.
The 48V Magic Pie Edge should produce ~20lbs of thrust @ 17.21mph 848W @ 80.7% efficiency.
~50lbs of thrust @ 4mph 1060W @ 38.1% efficiency.
The 36V* earlier 16" Magic Pies should produce ~20lbs of thrust @ 16mph 808W @ 80.1% efficiency.
~31lbs of thrust @ 12mph 1138W @ 66% efficiency.
*Unfortunately, I do not have any performance figures for the later 16" Magic Pie 4 or 5 with vector controllers, or earlier 16" versions running on 48V, but I would expect the speed figures under similar loads to be higher than the Magic Pie Edge.
The LiFePO4 48V 10AH aluminum cased battery is a good battery, but ideally it should be mounted over the front wheel
(if possible) to provide better traction on the driven front wheel.
