Sportivoo Bicycle Chain Freewheel Single Speed Non Gear Cycles Bicycle Brake Disk Bicycle Brake Disk

A single speed freewheel is a rear gear mechanism designed for bicycles with only one gear. It features a single sprocket and an internal ratcheting system that allows the rider to coast without pedaling. When the rider pedals, the freewheel engages and drives the rear wheel; when pedaling stops, the wheel continues to spin freely. This simple, low-maintenance component is commonly used on BMX bikes, city bikes, and kids' bikes. It screws directly onto the rear hub and offers smooth, reliable performance for casual riding or commuting.
