Diamondback Atroz 1 Full Suspension Mountain Bike (Teal) (20" Seat Tube) (L)
I am a fit 67 year old man in the Hell's Canyon area. I needed a source of quick, fun, aerobic exercise that would not stress my cervical fusion.
So this bike has worked out very well. It's a sturdy, entry level, full suspension Mt Bike that I ride for an hour or so a day on rough gravel roads. The shipment came on time and was undamaged. The bike was easy to assemble and I was riding in a couple of hours. I did need to get another seat that was better for an ageing mans prostate.
