This week's installment of Sexy Bike began with this handcuff lock-loving I Saw U a couple weeks ago. When I spotted a sleek gray bike cuffed to the rack outside hot bike hot spot Half & Half, I had to ask if it was the one from the ad. It wasn't, but it did turn out to be part of two best friends' ice-and-fire Supertwins pair.

This Week: The Supertwins

Riders: John Wagner and Molly Oakes
Bikes: Twin single-color single-speed road bikes, Frost has a princely Austro Daimler frame, Flames was scavenged from a Dumpster.
Spotted At: Half & Half on SW Oak

How'd you two wind up with Frost and Flames?
John: I built this bike and then a year later she built hers. They do kinda match. If by match you mean we should probably write a Scandinavian power metal song about it.

Why would you paint your bike gray when there's already so much gray in the landscape here?
John: Well, I'm pretty attached to the Portland landscape. I like the way it looks.

How do you think it's different riding around a gray bike than a bright red one?
John: The bright red bike would seem so flashy. I like my bike to look good, but I don't want it to way stand out or something. I used to have like a caution yellow bike and there was something about having a bike that was, like, that bright that just didn't appeal to me.

A lot of sexiness is about subtlety. Molly, your bike -- not so subtle. What are you going for here? Devil red? Tomato red?
Molly: Red of the beast. Hell red.

What's the deal with the monochromatic schemes?
Molly: Basically chance. I got a lot of this bike from my friends for free and they just happened to have tape that matched the frame. My friend Juicebox found the frame in a Dumpster and gave it to me.

You have a friend named Juicebox?
Molly: Ha, yeah.

With the handcuffs, are you going more for "policeman" or more for "kinkster"?
John: I'm going for "locks well to poles."

But that would be a kinkster.
John: Ha, well, maybe that is it and I just need to admit it to myself.
