Thanks to both Mike and Bob for their input as these machines rarely come up for discussion on the forum.
I understand the points you make Bob and I'm well aware of the limitations of roller brakes, having one of my bikes so equipped. They're not very powerful but they suit the typically easy-riding style prevalent in Holland and they never seem to need adjusting, at least very rarely and I appreciate them just for that. As a consequence, I tend not to ride very aggressively on my Dutch bike which is probably no bad thing!
At least with the Flyer C8, it's possible to choose which flavour of battery suits whereas my Gazelle limits me to just one off-the-shelf model which, as I mentioned in another thread, has shot up in price over the last two or three years. To be fair, mine is five years old now and is still good for most of the trips I do so, per annum, the cost isn't really too bad.
The styling of the Flyer bikes is not to my taste, having too many somewhat Chinese elements in the frame rather than the Germanic/Dutch frames with which I relate better having grown up with bikes like those. I'm sure though that someone will buy the Flyer on ebay and I'll be interested to see how much it sells for, not that I shall bid for it.
Regards,
Indalo
