I've met him as he came round with chain tension somewhat slack. He's a regular of Chris and Hannah at CS. Trike is a fixed wheel machine so needs to be ridden carefully. Nice guy (and dog CoCo) and big supporter of SfP - one reason I think why he decided now was the time to get one.
Suddenly I flipped over and landed upon the pavement with a loud crash. The bright yellow tricycle was now on top of me and though somewhat dazed and blushing with embarrassment, I managed to slowly came to my senses and upright my vehicle.
That's a problem with trikes. Everyone that's ridden one will overturn them sooner or later. Low down ones of course take more to flip over but it can be done. At an NMS Wheels and Wings event a teenager flipped an ICE Sprint by weaving it from side to side and applying one brake hard to one front wheel causing the rear to lift and turn over. He was ok but we had to report back as to how we allowed this to happen on a flat bit of road. Was accepted and we had taken out massive insurance for event of course.
