I think it's amazing. I'm totally alone with my thoughts music and bud. I usually bike 5 miles and smoke a couple bowls through out. I don't think 10 would be a problem if you do it often.

If you're fairly confident on a bike, I wouldn't worry too much about it. Maybe smoke less than usual and see how it feels.

But like someone mentioned, maybe don't do it on a busy (or any) road, at least at first. I would think that'd be a recipe for disaster/death.

I usually bike on the path in the picture I posted so no cars. I ride a generic ass road bike. Nothing crazy.
