Your height at 5.2 will be fine to ride these Trikes as they ate automatic so no shifting of gears required with your foot. Hope this helps let me also say it was a fantastic experience- Geoff

I didn't see any particular issues raised by the tour guides before my ride; however, I'm below the limit and wasn't concerned. I'd say to contact them directly before you commit to book the tour.

Total time from hotel was about 5.5 hours, about a 45 minute ride to the trikes, about 15-20 minutes of safety/riding in the lot to be sure you are comfortable and total on the trikes, about 3 hours. You actually go out on the highway for several miles and there is a couple stops for pictures, viewing, snacking, etc. Very much worth it, so much better than a bus tour. I hope this helps.
