I'm back to riding the citibike after a couple of weeks hiatus due to snow and WFH, missing out on the coldest weather. During the last few morning rides, the pedals feel real slippery, causing my foot to slip off a few times, including almost falling off while pedaling while out of the saddle, and a bunch of scabs on my shin. I eventually ended up pedaling with the arch or heel of my foot on the pedal and not being able to push the big gear (this is one time I don't really care if the NuVinci hubs doesn't go into overdrive...actually I still do, today's NuVicinci's overdrive was extremely low). On my ride back in the early evenings, I have no such issue.

I have been wearing some old Raichle boot of mine, granted the lugs are not as deep as my newer boot, but they still grip fine in snow and the thin film of ice that were on the sidewalk this morning. I was wondering if the cold weather are causing the pedals' rubber base to become non-pliable and losing its traction. I might have to bring one of those ice grippers slip on for shoes with me.
