Before buying new pedals, I decided to try and tighten the right pedal on my Roam. That was all that was needed. No more clicking and ended up saving money.
One thing that confused me though since I'm a noob with working on bikes, is that I thought pedal wrenches are 15mm. When I tried to tighten the pedals on my Roam, I had to use a 17mm wrench, since the 15mm and 16mm wrenches were too small. I did not have a pedal wrench, so I was just using regular open end wrenches.
