Dear Darrel,
We were suprised with your review since our guides and we as a company have safety first rules. The coastline especially is a bike ride done on 70% cycle road and through parks and some sidewalk. The crossing of the streets with the traffic-light and there were there is no traffic light you may recall the guide stops the cars with a hand signal so you can cross with safety. Which was easy since you were the only 2 on the tour and always close to the guide. The tour guide recalls the tour very well, you also wanted to stop for food and pina coladas which you did and on the way back she was extra careful because of the pinacolada :) That is also why the tour lasted longer than the 3 hours.
The tour guide is Dutch and knows very well how to ride safely, of course Athens is a busy city with traffic and even crossing a street might seem scary to you in comparison to the states but in no way we would put anyone at risk and until now our reviews had never any remark on our safety…on the contrary. We suggest always to wear a helmet to our guest as you did but since we do not ride in traffic it is up to the guide to wear a helmet her/himself or not. Thank you!
