I would love to give them a try on some of the bike paths through the forests round here, but I don’t see quite how they work.
See a few people training with those red things in the forest. One guy out near the fossil pits usually towing a kid in a kiddie bike trailer.
Since they’ve been randomly “repairing” the paths round here recently with new stonechip, I’d be more worried about how you make them go, rather than stop. Was like riding on a beach on my CX bike the other day on one of the main bike paths. Hope it all settles soon.
I guess on that type, you lean down and pull the lever? Or get really clever and actuate it with the ski poles?
