Re: Hello people, I am a heavy commuter at least 34 miles a day.
I think your best bets for durability are:
Worksman (or any industrial bike) or a chromoly steel MTB.
You will not find chromoly steel in bikes that retail for $99.
There are plenty of used chromo steel mountain bikes around.
The frame tubing sticker is usually on the seat tube.
My motor bike frame is Tange chromoly and has been bullet proof.
The frame cost me $10 at a swap meet.
