I live in student accommodation, which means I cant store my bike inside (€100 fine), Although there are bike racks outside they are unsheltered. There is a bike rack which is half sheltered (Like a bus stop), but that is a 5 minute walkaway, not great as I use my bike to go to classes a lot. I can hire a bike locker but that is a ten minute walkaway. I use my bike to go to work on weekends, around 20 minutes each way. I live in Ireland and it rains around once a week, worse in winter of course. Since bikes deteriorate in the rain is it better to buy a single speed bike for less moving parts, or maybe use a bike shelter.
