Dear Bonnie, the problem is you both have almost no confidence riding a bike even in a leisure way unfortunately so, if you never cycle, I’m wondering why you booked a bike tour: there are many other things to do in Lake Como.
This itinerary is easy to moderate and Ebikes make climbing effortless. It is not required to be athletes at all but it is required to know how to ride a bike.
The itinerary is on cycling lane and secondary roads, where else would you ride a bike?
I am a professional bike guide, of course I look and dress like a cyclist…
The average speed of your ride was 5 miles per hour (so likely walking speed). I adapted it to your skills in order to keep you safe.
You touched the wall 3 meters after resuming the ride after one of the stops for pictures: it’s not the fault of the bike if you didn’t steer the handlebar neither mine.
You didn’t made it to Switzerland because you spontaneously chose to abort the ride after the walk in the Valley Garden.
Luckily that day the tour was private for you two only otherwise it would have been a problem for other guests experience.
