OP isn't going to lock up the bike, it is going to be taken inside to classes so n/p. I don't even have folding or removable pedals on my pakiT, because they weigh more than good lightweight fixed pedals. Never been an issue because the bike is always close enough that I can get to anyone who might mess with it. Just have to be careful when I carry it to position the pedals right so they don't scrape me.
