Reply To: Is It permitted to ride a bicycle on shabbos?

DY, I do not understand what “chadash assur min haTorah” has to do with it. I also do not understand the problem with the rider’s body moving. This is also true of walking. As for the Shailat Yaakov, he is talking about a place where there is no eruv. The problem of possibly going outside the techum also might not apply today as the area of continuous houses is enormous.
