I'm looking for a folding bike to ride for fun and having some fresh air during lunch time. The Dahon D7, Dahon C7A vybe & Tern C7 seems pretty interesting and within my price range (i think all 3 are around $450)
I believed the C7A and C7 are Aluminum frame and the D7 is a steel frame. What is the difference between Aluminum and Steel since their total weight seems to be close? Which one is better? Any other recommendation for this price range. Also, where is a good place to buy?
Thank you for your comments in advance.
