My sister-in-law is looking to get a bike for my brother for Father's Day. He's not a cyclist and never will be. The bike is just to ride at home with the kids and also to ride around paved campgrounds. If he puts more than 5-10 miles a year on it I'd be shocked. A Walmart hybrid looks to be in the future for them.
With that said, my brother is about 6' and 220 lbs. What would be a good size for him?
