If you add the ZiZZO Rear rack and/or ZiZZO fenders, your ZiZZO Bike will fold normally. Because of the number of different manufactures of third party racks and fenders, we cannot guarantee if these other racks or fender would or would not interfere with the proper folding of your ZiZZO Bike. Though most "standard" or "generic" racks and fenders should work without any problems.
Please note that all ZiZZO Bikes have mountings for rear racks and most ZiZZO Bikes have mounting point for fenders as well.
If you have any other questions, please let us know.
