Hi Mel, thank´s Mel, i like to help Frank

Bosch regards frank

yes, lower rpm means higher torque, in simple words but in a small wheel you dont need so much torque because the advance of the small 16" rim give you a lot more hillclimbing ability as an high torque motor in a 28"rim Important is what you want on speed and noise, speed and torque you...

i forgot the 3picture, now here we go

hi d8veh, good work with the swxk but you can do it better with a other way working clutch inside the swxk (1picture). Then you dont need to fix a freewheel on the left side and have more choisses for the sprocket and then you also can fix a freewheel crank so you receive double freewheel...
