Hello everyone! I'm new on the forums and wanted to ask if anyone knows more about the bike I recently acquired (for $50). It is an Open Road hybrid men's bike that was distributed by Montgomery Ward and made in Korea, 18 speeds, Shimano gears, and the rack is original and came with the bike. The side says A.T. 600, and I am assuming that is the model. However, I could not find anything about this specific model. Any info would be greatly appreciated!
