You could remove the crank-end plug, and see if it will rotate backwards half a turn, or so. If it does and then stops again, pull the plugs like Mike said, and re-evaluate.
Hard boil some eggs on the weekend and put them in the fridge for the rest of the week. It's amazing how far two eggs will let me go before I get real hungry again. I like to put salt and pepper on them, or better yet a splash of Frank's red hot.
I've thought about trying the zip-tie method, but knowing what good zip-ties cost these days, I figure it's just easier to take it to a shop or go use my friends No-Mar. Him and the bike shops are 20+ miles away, so gotta add that too.🙄
I rode my Grom today. No tripling, or even doubling of speed limits (no school zones on my route). However, I very briefly did 10 over in a 60 zone when I caught a draft behind a pickup truck that was merging in. Thing rails in the corners though.
