The 85mm is not the width at the spindle but at the outer peripheral of the motor. This is why he said in the description the width of the actual forks i.e. above the slotted flats holding the spindles where the forks narrow. This is only an issue on some shock forks.

Now that I have done a couple of bikes if I wanted to do another I suspect now I have the knowledge and experience of the systems I would buy dirct from China. I have already bought an extra controller and twist throttles direct from eCrazyman but these did involve a little reconfiguration of the pins in the plugs/sockets but that was not a great problem. If you buy the motor with the extras (controller etc. this makes a package sourced direct an interesting proposition.

Its worth knowing the battery from Alien is switched and fused and in a metal case also the rack is a slide in unit for the battery and the battery switch also locks the battery in place. I have not seen these in my searching but they will have come from China. For my wife I would have wanted a tidy, easy to use system with nothing exposed or hanging loose and the kit met that criteria. Whether the extra money is worth a complete system with support and guarentee is up to the buyer. Whatever you do enjoy, as I said they are good fun and I believe encourage the user to get out and cycle.
