Wanted: 2.0 HDI Starter Motor

[Piggy]

Less teeth, less strain on starter but also less speed of turnover.
More teeth, more strain, but also more speed....assuming the starter must be a higher wattage too?!

Im thinking like a bicycle gearing by the way, coz early here too!

This was my thinking but been years since i was on a pushbike

I thought if you had a larger cog with more teeth it made life easier at the expense of speed?

Yes but at the wheel, not crank. (bicycle)
The wheel is the flywheel and the crank is the starter.

So if you had a bike with like 21gears with 3 options for gears at the pedal crank, think what happens if you change one of the gears at the pedal crank...not at the wheel!
