trikke

Question

Hi Rabbi, From searchin old posts on the website my understanding is that the problem with riding a bike on shabbat is that there is a seat and would be considered maarat ayin. It would look like you are traveling a long distance and going on a trip. Would I then be able to use (in a kosher eruv of course) 1. rollerblades 2. scooter 3. trikke (similar to a scooter http://www.trikke.com) All of these things do not have a seat and you would be satnding at all times. Thank you for this informative website and the ability to pose my own questions.
