Transportation on Shabbat
From Halachipedia
Bike
- The Minhag is not to bike on Shabbat. [1]
Car
Electric Subway
- If one needs to travel for a mitzvah (such as a doctor to the hospital, or a Mohel to a Brit) it is permissible to take an electric subway, where the driver is non-Jewish, majority of the passengers are non-Jewish, and it only travels within the city, as long as one pays before Shabbat and is let on without giving money or a card. Additionally, as much as possible a person should do this in private. [2]
