What is a VIN?
Every bike and trailer we sell has its own unique number, known as a frame number. Our frame number consists of our own manufacturer’s mark “CS,” a serial number, and a year code. We keep track of all our models using the frame number.
Where is the VIN located?
The frame number is located in different places on our cargo bikes and trailers. On the trailers, the frame number is stamped on the side of the bottom tube. On the yellow-galvanized steel frames, we have stamped the frame number on the left side of the plate located between the top and down tubes. On aluminum frames for rearDrive or frames for cargo bikes without a motor, the frame number is stamped on a plate under the bottom bracket. On midDrive aluminum frames, the frame number is stamped on the seat tube just above the motor housing.

How old is my model?
If you send us your serial number, we can give you the exact date your model was manufactured. You can also find the year yourself by looking at your serial number. The last letter in the serial number indicates the year of manufacture. You can use the following guide to find out when your model was manufactured. The letters A–Z are used, except for I, O, and Y.
