What do you mean about hanging on the wall? One of the things you are getting for your $5k from Specialized is light weight. They have ebikes down to 34 pounds, about half what a radrunner weighs.
Yes, the Specialized is much lighter. I mention still being able to hang the bike because that's the situation where I notice the extra weight the most. If I couldn't, it would have been a deal breaker for me.
