Honest question--you say that bike is "not strong", but he's a 300 pound, 6'3" rider. Is there any way that bike is going to fit him and hold up? As you know the WM bikes go for the one-size-fits-all approach, and he's going to be hard to fit.
In his case, at least, I think they're going to need to spend more to get a bike that's big and strong enough.
My son's not that tall, but he's a bit heavier. I bought him a Specialized Roll.
