I recently got an old Miyata 210 I think it's from 1984, but I want to customize it to make it a really cool and unique commuter bike for when i go to college this summer. I was considering turning it into a fixed gear but then i heard about flip flop hubs where i can have both fixed gear and free wheel! I was just wondering what peoples opinions were on this and I am open to any other suggestions for modifications

I will be posting pictures of this bike soon and probably even update them once i start working on it!
