Spending $150 on a beater commuter/training bike to get past the above issues is worth it for me.
Why is it necessary to justify one's questions here?
I think Gear was trying to understand not attack. It would strike most BF readers as odd that somebody posting here about a trainer doesn't have a rideable bike already.
