Good bike for a good price!

Top bike for a great price. We had chosen to have it delivered to our home and assemble it ourselves. That worked, but getting the pedals on was a hassle... it seemed like they didn't fit. Next time I would have it done in the shop to make it roadworthy. Otherwise satisfied. Very well helped by a salesperson in DH!
