FAQ

Frame number

Where is the frame number located?

The frame number is located different places depending on the model you have. If you have a trailer from us, the frame number is located on the side of the bottom frame. If you have one of our cycles, you first have to stand behind the rear wheel of your model. On pre-2000 models with double tube frames, the frame number is engraved on the left side of the plate that joins the upper and lower tubes. The frame number is never on the right! On the mono-tube frames, the frame number is on a plate under the bottom bracket. In powder coated light models, the frame number is also painted on the seat tube well below the saddle – again on the left side! Please also see the following images.

What is the frame number?

Each cycle and trailer from us has it own unique number, which is named a frame number. Our frame number consists of our own manufacturing stamp (CS), a serial number, and a year number (the last letter). We keep records of all our models with the use of the frame number.
