Jerusalem had them so of course it was a matter of time until Tel Aviv got segways. There is a company that now offers guided segway tours either on the beach promenade or through the Yarkon Park. It is very easy to ride and control a segway - the vehicle operates no greater than 13K per hour, it works to stay upright and it is very easy to stop. And it is a fun ride.
My husband and I opted for the Yarkon Park tour in the evening hours. We really got to see the Yarkon Park (which I never realized was so big or beautiful) and its points of interest. As the sun was setting and we were whizzing through the park, life could not have been better.
