The Giant Roam is a cool looking Bike, I just Googled a Pic of it. Just do it !! Remember the most important thing is that it fits you, so make sure you get the right size, the Bike Shop should beable to help you with that. And don't forget the Helmet!! And a Track Pump to inflate the Tires. Oh yeah, and a water Bottle Cage with a Bottle.

I quit riding a Bike when I was 15, then bought a Hybrid 30 years later for $250 , I struggled to ride 4 miles but just rode as often as I could, base miles are the key, just ride, you'll be amazed how fast you will progress if you stick with it.

18 months later I did my first Century on a Road Bike, I was riding 6,000 + miles a year.

A week after buying the Bike you'll forget about the cost and be wishing you'd done it a long time ago. Have fun!!
