Ok. then she wil get used or if not get a der bike.
I find the two hubs I use are different. The Nexus7 wants the pedals in just the right spot when I start riding. If the bottom one is slighthly behind the center of the BB then I end up braking instead of starting the ride.
The Sachs Spectro S7 isdifferent . This one also has got a coaster brake, but if the low pedal is just behind the BB centerline on this one it doesnot brake.The pedal just goes slowly back to the "straight down" position and I take it from there.
