My friend's bike had an issue with the battery as soon as we got the bikes but the staff seemed to think we'd be OK. After about 1km my friend said her ebike wasn't working so we called and they exchanged the bikes, but unfortunately this made us quite late for the lighthouse tour which was why I had arranged the trip.
I fell off my bike a couple of times because it was too big for me and I struggled to flex my hip high enough when getting off as I'm under 5 ft.
I thought the staff were helpful but I think having correct sized bikes would definitely have improved the experience.
