Also for handlebars? I would double the size of the front, back, and flap pieces (cutting half as many of them), make the side pieces twice as wide but more than twice as long (not doing the arithmetic here this morning, but add at least 2 inches to the length – you can trim them down once you see how much goes around). You can keep the closure the same, though with a wider bag you might decide 2 closing “buckles” works better, spaced outward from the center.

Skip the joining tabs, and replace the one long handlebar strap with 2 straps each 2″ by 10″. Prep those similarly to the handlebar strap, except you only need to finish one end. Then I would insert the unfinished end into the top of the bag the same way the top joining tab is in the 2-bag version, but spaced apart from the center (I’d have to see what the bag looked like against the bike handlebars, but I’m guessing about 1/3 and 2/3 of the way across would be good). The snaps would then join the straps to the back of the bag.

Hope that helps, just a rough idea of how I would go about it!

I see what you did there. 😉

No prob.

Hey, thanks! Especially for helping me pick the buttons. 😉
