So with moderate/heavy pedaling you could hit 25 MPH? That is what I am shooting for with tailwind and/or slight downhill, to make up for the 6-7 MPH uphill.
The gearbox is on SWXK or SWXH or SWXB always the same the different speed comes from copper windings inside the motor and in this way the realise different rpm for different wheelsize. 175rpm is for 28",195rpm is for 26", 220rpm is for 24",255rpm is for 20", 275rpm is for 18" and around 320 is for 16"

Used for a mid-drive, this gets your cadence in the normal range, with normal bicycle sprockets, and chainrings. Unfortunately, all the geared hub motors I am aware of are wound for 36 volts at 20 mph.
On the other hand, If I ran a geared hub motor on 36 volts, the lighter weight would offset the extra weight of a 36 volt, 30 amp Ping pack! Same total weight, more range....but both the hub motor and the battery pack would be more expensive.
