My thanks to all who have given impartial advice.There is a lot of choice out there and more possibilities have come into the frame eg Kalkoff @£999. I feel I need to take time and go to a big dealer and try different bikes. I thought I wanted a throttle but have never tried a bike with one, so I will try before I buy and make a more educated decision.I would be prepared to buy second hand through Woosh as they check bikes over and sell with a guarantee. Sadly they do not have any returns of the models I am looking at currently.
