First stage vs Second stage mid drive kit:
First stage mid drive kits are installed right behind the bottom bracket and drive the original chain. Which makes it less observable.
Second stage mid drive kits are installed in front of the bottom bracket and drive the crank wheel using an additional chain. The crank wheel then drive the original rear freewheel system to power the bike.
