Radwagon 4 in SF bay area?

[barato_bikes]

Greetings, hoping someone in the SF bay area will be able to help. Kind of a random question - does anyone in the SF bay area have a RadWagon 4 that I can take a peek at? Looking to see if my custom made bag mount (made for RadWagon 3) will switch over before I pickup a new bike. Will compensate you for your time!
