Mini Step Through - same problem. I think there is a design fault. too many incidents.

This happened to my wife riding a Rad Mini Step Through. Broken arm and lots of bruises and cuts. Bike had been checked over by mechanics at Rad store, so no issues with assembly. There is a potential design fault in that the recessed areas on the fork where the quick release skewer nuts land on the forks are so close in diameter to the nuts that the skewer can work loose without the rider noticing. First indication is under braking on a downhill when the force is enough to rip the wheel clean off. On a normal bike, quick release coming loose is easy to notice. Not so on this one. Mechanic at store told me this was the second one they have had.
