Is there any scope for putting the seat back in a way as to increase the leg room ?
Yes, There are two sets of holes about 4cm apart. Mine was bolted to the front set. Take a look, you may find you can get another inch or two - John M - 16th March, 2001

Easy, Just four bolts, Allen key head. You need the right-sized right-angled key and hopefully not too much elbow oomph. Seat and all the electrics/motors etc all in one chunk with just one plug to disconnect carrying power. John M - 16th March, 2001
