This is just a concept we'll make better versions as we go it's just a test.
This design is clutches (motor brakes) to stop on the main flywheel at certain rates providing more speed and power each gear.

Anyway.

Controls:
all "gears" are not on numpad!
1= first gear
2= 2nd gear
3= third gear
4= fourth gear
Right arrow key= drive controller
Down arrow= brake
Gear selection keys do not need to be held once engaged they stay engaged until you hit the gear number key again.

DRIVE LINE WILL SPIN FAST WHEN ANY GEAR IS ACTIVE UNDER NO LOAD!
For best performance do not disable each gear as you add another I.E 1st gear is active, activate 2nd gear on top of it so on and so forth.

EDIT!
3rd and 4th gear are the main powerbands in this set up!
