The becco solid axle coupler M12 x 1.0 is the perfect complete solution for bikes with a solid axle or hub gears. The set combines the innovative becco towing part with the robust solid axle adapter made of rustproof stainless steel – perfectly matched to each other for maximum safety and comfort. Together with the becco tow bar head of your trailer, they form a safe, comfortable connection. The solution is derived from the proven coupling technology of the traditional brand Leggero and has been decisively improved once more by us. The result is a ready-to-use coupler that sets new standards in terms of safety, ride behaviour and ease of use.

The complete solution – perfectly matched
With the becco solid axle coupler you get everything you need on your bike for the secure attachment of your bike trailer. The solid axle adapter is firmly mounted on the rear axle of your bike, with the becco towing part attached to it. Both components are perfectly matched to each other and, together with the becco tow bar head of your trailer, form a robust, durable connection that meets the highest safety standards.

Easy coupling thanks to the becco coupler system
The becco tow bar on your trailer makes coupling child's play: place the tow bar head onto the towing part, close the magnetically assisted clamping lever – done. You hear and feel the reliable engagement. No awkward fiddling, no complicated manoeuvres. This is everyday usability as it should be.

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

Precise alignment – guaranteed
A clever design principle sets the becco coupler apart from conventional systems: alignment and fastening are separated from each other. The towing part is placed onto the mounting spigot of the adapter and can be freely rotated before fixing. This way you align it effortlessly into a horizontal position – the ideal position for optimal power transmission. The screw then fixes it in this exact position, without the towing part being able to twist.

The advantage over classic couplers: with conventional systems the coupler rotates uncontrollably as it is tightened – the final position is unpredictable and often slightly skewed. The becco coupler instead guarantees precise alignment during installation. Once correctly set, this perfect position is retained permanently.

Robust and durable
The solid axle adapter is made of rustproof stainless steel and is designed for lasting loads. The high-quality workmanship and the solid materials guarantee a long service life – even with intensive daily use.

Who is this coupler suitable for?
The becco solid axle coupler M12 x 1.0 is ideal for:

• Bikes with a solid axle and hub gears
• Thread size M12 x 1.0
• City bikes, trekking bikes and e-bikes with a corresponding axle
• Anyone looking for a ready-to-use complete solution

Not suitable for:
Bikes with a carbon frame, carbon dropouts or carbon rear triangle (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 retrofitted to the new system, and Leggero models are already compatible. This way you get the maximum out of your proven trailer – state-of-the-art technology instead of buying new.

The becco coupler system – briefly explained:
The innovative becco coupler system sets new standards in terms of comfort, safety and flexibility: the magnetically assisted clamping lever on the becco tow bar head engages reliably and effortlessly on the towing part and makes handling easier than ever before. Thanks to the optimised connection with separate alignment and fastening as well as the resonance damping integrated into the tow bar head, you experience a stable and controlled ride feel, even when riding sportily out of the saddle. Thanks to comprehensive adapter solutions, the system remains compatible with almost any bike and can also be retrofitted to older trailers without any problem. This means you are perfectly equipped not only today but also in the future, to enjoy every ride safely and comfortably.

Distinction: adapter vs. coupler

• Solid axle adapter: connecting piece for attachment to the bike – without towing part. A functional coupler additionally requires the becco towing part.
• Solid axle coupler (this product): complete set of solid axle adapter and becco towing part – ready to use right away.

Important:
Only the combination of towing part and adapter forms a functional coupler. With this set you get both components in perfect harmony.

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

Which product suits your situation?

• You want to use the trailer on a second bike: a complete solid axle coupler.
• You have a new bike (switched from quick-release to solid axle): only the solid axle adapter – the towing part is already there.
• Your bike has a different axle (thru-axle, Giant attachment): only the matching adapter.
