The becco quick-release coupler M5 x 0,8 is the complete solution for bikes with a quick release or hub gears. The set combines the innovative becco towing part with the robust quick-release adapter made from stainless steel, perfectly matched for maximum safety and comfort. Together with the becco tow bar head of your trailer, they create a secure, comfortable connection. This solution is based on the proven coupler technology of the traditional Leggero brand and has been decisively improved by us. The result is a ready-to-use coupler that sets new standards for safety, road handling, and ease of use.

The complete solution, perfectly matched
With the becco quick-release coupler, you get everything you need on your bike for securely attaching your bike trailer. The quick-release adapter is firmly mounted to the rear axle of your bike, and the becco towing part is attached to it. Both components are perfectly matched and, together with the becco tow bar head of your trailer, create a robust, durable connection that meets the highest safety standards.

Easy coupler thanks to the becco coupler system
The becco tow bar on your trailer makes coupler effortless: place the tow bar head onto the towing part, close the magnetically assisted clamping lever, and you’re done. You hear and feel the reliable click into place. No awkward handling, no complicated steps. That is everyday practicality exactly as it should be.

Noticeably better riding characteristics
The resonance damping made from BASF Elastollan® TPU integrated into the becco tow bar head makes the difference: the highly elastic polyurethane, with its outstanding damping properties and high tear resistance, creates an optimized connection between coupler and tow bar. You enjoy a significantly more stable riding feel, especially when riding out of the saddle. The wear-resistant material reduces disruptive vibrations and ensures smoother, more comfortable riding on asphalt as well as bumpy forest paths. An integrated safety cable provides additional safety in all conditions.

Precise alignment, guaranteed
A clever design principle sets the becco coupler apart from conventional systems: alignment and fastening are separated. The towing part is placed onto the adapter’s mounting spigot and can be freely rotated before fastening. This lets you align it horizontally with ease, the ideal position for optimal force transfer. The screw then fixes it in this exact position without allowing the towing part to twist.

The advantage over classic couplers: with conventional systems, the coupler rotates uncontrollably during tightening, making the final position unpredictable and often slightly crooked. The becco coupler instead guarantees precise alignment during assembly. Once correctly adjusted, this perfect position remains permanently in place.

Robust and durable
The quick-release adapter is made from stainless steel and designed for long-term loads. High-quality workmanship and solid materials guarantee a long service life, even with intensive daily use.

Who is this coupler suitable for?
The becco quick-release coupler M5 x 0,8 is ideal for:

• Bikes with a quick release
• Thread size M5 x 0,8
• Anyone looking for a ready-to-use complete solution

Not suitable for:
Bikes with carbon frame, carbon dropouts, or carbon rear frame (risk of breakage!).

Sustainable and future-proof
Already using a Qeridoo or Leggero trailer? The becco coupler makes your investment future-proof: older Qeridoo trailers can be converted to the new system, while Leggero models are already compatible. This lets you get the most out of your trusted trailer: state-of-the-art technology instead of buying new.

The becco coupler system, briefly explained:
The innovative becco coupler system sets new standards for comfort, safety, and flexibility: the magnetically assisted clamping lever on the becco tow bar head clicks reliably and effortlessly onto the towing part, making handling easier than ever before. Thanks to the optimized connection with separate alignment and fastening, as well as the resonance damping integrated into the tow bar head, you experience a stable and controlled riding feel, even when riding sportily out of the saddle. With comprehensive adapter solutions, the system remains compatible with almost any bike and can also be retrofitted to older trailers without difficulty. This means you are perfectly equipped today and in the future to enjoy every ride safely and comfortably.

Terminology distinction: adapter vs. coupler

• Quick-release adapter:
  Connecting piece for bike attachment, without towing part. For a functional coupler, the becco towing part is also required.
• Quick-release coupler (this product):
  Complete set made up of quick-release adapter and becco towing part, ready to use.

Important:
Only the combination of towing part and adapter creates a functional coupler. With this set, you receive both components perfectly matched.

Good to know:
Current Qeridoo trailers are delivered with a quick-release coupler (towing part included).
