I’m 70 and the Fiido C11 Pro is my first E-Bike ….. so far, I’m loving it a lot, including the colour. Despite my initial reservations about buying online, the experience was surprisingly pleasant and without any problems. I was given advance notification of its delivery and it arrived well packaged and, with the help of the video, assembling it was very straightforward. I’m about 5’8” and there’s ample adjustment in the seat position/height and the handlebars. So far, I’m still mostly cycling with minimum use of the battery and pedal assist but being able to engage this and the hand throttle for the hilly bits is making my cycling much more enjoyable and enabling me to cycle much further afield. For me, the seat is OK for shorter trips but its hardness is definitely felt by me over longer cycles and becomes uncomfortable so I have added a padded seat cover. I also bought the panniers which were delivered a few weeks after the bike and I’ve found them very spacious and useful.
