would like the a28 400 as i plan to remove my chains and 250mm wheels and replace with gears and 125mm wheels, making the complete drive system more compact and lighter.
will have to ask the nipper guys if they could run them on a watty, im sure they use a megawatty though. I have to do this as I want to reshape the back in at the bottom so I can also remove the wheely bar and wont get stuck on the rear end.
