What is the meaning of "Cyf" after Burtech?

“Cyf.” Is short for “Cyfyngedig” and means “Limited” in the Welsh language, so, if it was an English company, “Burtech Cyf.” would be “Burtech Ltd.”


What is the difference between un-braked and braked?

An un-braked trailer has no braking system at all. On the move it relies on the towing vehicle to retard it. When parked and disconnected from its towing vehicle it must be chocked or otherwise secured. The maximum gross weight that an un-braked trailer can be is 750kg, although lower restrictions may apply depending on the vehicle pulling it.

A braked trailer, most commonly, has an over-run braking system. As the towing vehicle slows, the trailer pushes onto the back of it. A mechanical connection from the coupling to the wheels causes brakes in the hubs to be applied, slowing the trailer down. You would expect that this action would cause the brakes to apply if the towing vehicle was to reverse, pushing on the trailer. A mechanism within the brakes allows the trailer to differentiate between the brakes being applied to slow the trailer when going forward and when is being reversed. This is known as “Auto- reverse brakes”.

When a braked trailer is parked and disconnected from its towing vehicle, a handbrake lever near the coupling is used to apply the brakes, removing the need for it to be secured in any other way.


What is the difference between O1 and O2 category trailers?

European Type Approval regulations dictate two categories of trailer within our range.

01 trailers have a maximum gross weight of up to 750 kg

The actual gross weight (maximum 750kg) is stamped on the chassis plate riveted to the chassis and the category is identified in the chassis number stamped directly onto the chassis.

For this reason, it is not possible to change the category of a trailer after manufacture.

O2 trailers have a maximum gross weight of up to 3500kg, but are marked as outlined above. Our largest trailer, the C8 – O2 is marked as 950kg.


All Burtech bike trailers and the C6 and C2 canoe trailers are category O1, as none exceed a gross weight of 750kg as marked on the chassis plate.

The C8 canoe trailer can be supplied as either category O1, plated at 750kg, or as O2 plated at 950kg. Both trailers are exactly the same except for the stamping on the plate and chassis. Again the category is not transferrable after manufacture.

The O2 trailer has 200kg more payload, but may exceed the weight that may be towed by certain drivers and/or certain vehicles, in which case the O1 may be more suitable. This will have to be looked into by the user by reference to ‘.gov’ websites to see the current regulations.

The C8 is a modular design and, as such, its weight can vary with the different equipment that can be fitted to it, for instance, extra arms, equipment cage or box etc. This will affect the available payload.
