Thanks again Dave for your help.Occasionally we have a customer who insists on putting their foot flat on the floor at stop,this is a sure way of wrecking your knees when riding.
Because of my dodgy knee I need to be as far away from the pedal as possible. It's second nature to get off of the saddle when I stop. Until 3 years ago I was doing all my shopping on the hybrid with no problems but I lived in a very flat area - now I live at the top of a steep hill!
My budget is up to about £2,000 so the Tornado is well within that even given that I will want to add a rack, mudguards, lights etc. Just to check, the Tornado does have a speed sensor, not torque? I appreciate the offer of sending the bike back if it's not suitable - I had made up my mind to go the the LEBC in a couple of weeks' time (we've been in Italy and France for a month and will have to catch up with gardening before I can think about a bike!) but it's maybe not worth the trip if the Tornado is the best one for me anyway. I will definitely want to add a rear carrier and have found the link on here for what I'd need.
Getting closer to a decision then!
