I have a few suggestions that may help.
First, I have invented a new product. With it, you can scale any mountain with your bike over your head!

When you see this in coolers by next year, you'll know you saw it first on 409 gals.

Secondly, it is a little known fact that THE LIGHTEST BIKES OF ALL are the invisible ones.

But don't be fooled, they're not without hazards.
It's an even lesser known fact that my preferred method of locomotion is actually levitating. I highly recommend it.
Notice the shadow. I love hovering over ancient Moorish castles. Don't you?
The only fuel required for this is beer and beans.
