Review on 🚲 ZUKKA Single-Speed Bike Freewheel: 16t/18t/20t Bicycle Flywheel for Smooth One-Speed Cycling by Kyle Ziegler

This item was originally included with the trike I bought. After two months he started hopping and then stopped. I disassembled it and found loose ball bearings, a ratchet and pawls, gnawed. A perfect replacement has arrived. I immediately heard something rattling inside. Then he chose a replacement. The second clicked too. So I sent it back. It was a smooth and easy process. The products arrived quickly. Easy to return. You just pushed back time.
