Aluminum bike trailer with a 19" by 30" cargo area (approximately). The length can be extended by either 32" or 64" using the extension shown in the picture. I have carried an eleven-foot kayak on this trailer. Comes with hitch (which mounts to chain and seat stay), instructions, and all necessary hardware. Read more about the trailer on the Bikes at Work website. Mine is the model 96A with the Schwalbe Marathon tire upgrade. The current iteration on the website is the 96B, but it looks like they haven't changed all that much. I do not do venmo or any other money transfers, so will need payment in cash. Note: the kickstand and 4" front roller wheel you see in the pic are included but can be removed.
