Cycling parents, this bike trailer coupler makes attaching kid trailers so much easier! Made from high-quality metal that resists corrosion and rust, this thing is built to last. The specifications are spot-on: connecting part to bicycle hole diameter is 11mm, nut fixed diameter is 22mm, embedded trailer hole diameter is 7mm, and the insert diameter is 13mm with a total length of 20mm. Installation is straightforward - just secure it to your bike with the included screws and nuts, then insert your trailer and pop the pins in place. The safety factor is high since everything locks securely and won't come loose during rides. I've used this with several different trailer brands and it works perfectly every time. The metal construction feels substantial and reliable - not some cheap plastic that might fail when you need it most. It's compatible with most standard bike trailers for kids, pets, or cargo, which is super convenient if you have multiple uses for your trailer. The included connecting pin is designed not to fall out accidentally, which gives you peace of mind when pulling precious cargo. Whether you're commuting with kids, going on family bike rides, or using your trailer for groceries and gear, this coupler provides that secure connection you need. Definitely a must-have accessory if you regularly use a bike trailer - makes the whole setup process quick and worry-free!
