I just moved to Uptown in Minneapolis, MN and commute to Bloomington via Penn Ave on a road bike almost daily for school. I am planning on converting an old Huffy Stalker Mtn. bike to a singlespeed for the winter commute, and wanted to know if anyone knows of pitfalls or safety issues I should address before I take one of the biggest plunges of my life. I just started commuting less than a month ago and find it to be a great way to get motivated for the day. The rest of the forums are great, I'm learning a lot. Thanks in advance for any advice!
