What it does
Need to attach a small trailer to a bike quickly? This towbar bolts to the seat clamp screw and provides a secure point for your trailer’s coupling.

How to use and compatibility
Fitting is usually straightforward: attach the towbar to the seatpost clamp screw on your bike. Tools needed are minimal — typically a spanner or an Allen key depending on your clamp hardware. A friendly heads-up: seatpost clamp designs vary, so give the screw position and diameter a quick once‑over before buying. If you’re unsure, compare the clamp screw location and measurements to your existing hitch or check with a bike mechanic. Works best for small cargo or child trailers and many common tow couplings, but it isn’t a universal solution for every trailer type.
Why choose this Ventura towbar?

Ideal for keeping as a replacement part or fitting when refurbishing a trailer connection. If you’ve got an unusual seatpost or bespoke trailer coupling, that’s a fair point — just double-check dimensions first.
