Your diagram, 10s2p is 37V 4400mAh = 37V 4.4Ah
I am hoping these are new cells?
2200mAh cells are either very old laptop or reasonably new higher C rate cells.
Cells should be tested, even new cells, then connected in parallel with balance leads-wires.

Homemade Battery Packs
Your cells, in diagram, as connected, without parallel balance leads, could be comparative capacity tested.
If all new or reasonably same condition, same brand-model cells.
Make sure all cells are at identical voltage.
Simply discharge and measure every cell at timed intervals.
Comparative capacity is determined by voltage loss.
Rate by final voltage after timed discharge, (eg. 1 hour of 1A discharge?)
Any with exceptional voltage loss should be eliminated as defective.
2200mAh laptop cells will be hard pressed , at 10Ah, to motivate an eBike.
Cells for power tools etc., higher C rated, might do just fine ...
