Question: Is it permissible to rent a bicycle to non-Jews for riding on the Sabbath? Response: This has been clarified by Maran’s words in Section 246 paragraph 1, who wrote: “It is permissible to rent implements to non-Jews on the Sabbath, despite that they use them for outright labor, since we were not commanded about implements”. This is the law in our case; it is certainly permissible to rent and this involves no prohibition.
