SUMERIANS TARTUF Co-Pilot Bike Trailer Spare Hitch for Weeride Co-Pilot — Steel Clamp 25–35mm with Quick-Lock Pin & Bell

The SUMERIANS TARTUF Co-Pilot Bike Trailer Hitch is a steel spare hitch and bell kit that lets another bike tow a Weeride Co-Pilot child trailer quickly and securely.

Need an extra tow connection for a second bike or a replacement for your original mount? This spare hitch is made to fit Weeride Co-Pilot kid trailers and bolts onto a wide range of seatposts, giving you a reliable way to share the trailer between bikes. The package also includes a sturdy bell so the towing bike can signal traffic and pedestrians while connected.

How does this spare hitch attach to my bike?

The hitch clamps around standard round seatposts between 25mm and 35mm, using a steel construction and rust-resistant finish for durability. A fast-lock pin secures the trailer arm quickly and allows easy removal when you want to disconnect.

Who is this for? Parents, caregivers, or anyone who already owns a Weeride Co-Pilot child trailer and wants the convenience of using the trailer with multiple bikes or keeping a replacement hitch on hand. It’s ideal for households with more than one adult bike, rental shops that rotate trailers between bikes, or cyclists who need a durable spare part to avoid downtime. Note: if your trailer is not a Weeride Co-Pilot model or your bike uses a non-standard seatpost or proprietary hitch system, this kit will not be suitable.
