They couldn't afford another set of wheels?!

Pamela Anderson donned a tiny tan sweater and boots for a ride around Malibu yesterday, and the Baywatch babe threw husband Rick Solomon on the back of her bike!

They make two-seaters, but this wasn't one of those!

It must have been kind of hard for the blonde bombshell to lug all that extra weight!

Pammy seems like she couldn't be happier these days, and we have a feeling it has to do with her stable love life.

"He is the only man besides my boys that I trust. His way of helping the world to be a better place is by caring for me, protecting me and making me happy. I am so proud of him," she recently gushed about her beau.

We love these two together!
