What's better a bicycle trainer or a bicycle roller?

Question

which is better? and whats the cheapest roller and trainer that i can buy?

Answer 1

I have a trainer because I don't like falling and wasn't interested in the learning curve of a roller.  Rollers are a more authentic feel and aren't as loud.  Trainers are safer.

You don't want cheap with either of these or you'll burn them out pretty fast.

Happy trails!
