Most people quickly develop a tolerance for THC and feel less of the psychoactive effect after only a few days of regular use. So they might well be able to retain enough coordination and situational awareness to ride safely. Some friends are regular users and seem unimpaired during rides, skateboarding, etc.

Edibles are generally more potent, but take longer to hit -- one or two hours after consumption. Depends on how well it's been decarbed, fat/oil content in your diet during ingestion, etc.

But I wouldn't do it if I planned to ride a bike. I want my situational awareness intact and unimpaired. I ride and run to get that natural buzz from brain chemicals, which is just as good... on a good day. Some days it just hurts.

I only use CBD with a minimal THC content (the usual 0.3) and some days when I take more than usual for various aches and pains, I'll feel that familiar THC buzz as I'm drifting off to sleep. The worst I can say about CBD during daytime use while exercising is sometimes it makes me feel a bit lazy at higher doses -- some 200 mg gel capsules. Usually I take only about 10 mg doses in 1 ml droppers before exercising. That amount takes an edge off the aches and pain while the body warms up and delivers the magic chemicals -- serotonin, oxytocin, endorphins, dopamine, whatever the current theory says is happening.
