Thanks all for the replies. I have to admit I'm a bit gutted that things have not moved on in this area. I only check into pedelecs every 3-6 months or so now to see if there have been any developments, but am generally disappointed
. I am 6'5" with a bad back as a result of spinal tumours, my ordinary bike is a 23" frame with 700c wheels and I would ideally like something similar in electric format. The throttle option would be essential as I sometimes get a level of pain that can make cycling back from places very uncomfortable after a period of me not moving.
I do like the Wisper range & would stretch my budget to buy one, but having test ridden a 905 a couple of years ago, I have to admit that at 6'5" I found it a bit like riding a childs bike and it was just too small for someone of my size, I don't think the Alpino is sufficiently bigger in size to make a massive difference in that regard. The Kudos range looks pretty neat, but they just don't look big enough for me. I really did like my Alien Gents Special II & in some ways wish I'd kept it. The Alien Aurora presents a possibility, but I just don't want to use an illegal bike on the road, so that's just not an option for me.
Perhaps a further wait for the market to develop would be the best option....
