This looks awesome, I need to replicate this. I had a go on a heavy e-brompton recently (the first electric bike I've ridden) and it put a massive smile on my face. I'm not a strong rider at all, largely as I have health issues to do with my spine, so I've had it in mind for some time that this type of thing will benefit me greatly.
I see you cold-set the steel fork; did you have any issues fitting the hub in the ti fork?
Only my heart racing and sweat pooring down my face in terror as I did it.

It was a risk but I have done it before on my Brompton steel forks. Harder on Ti forks and I may live to regret it, but hey you only live once. At worst it will cost me a new set of Ti forks.
You also have to take a little "metal" off either side of the dropout for the larger motor shaft, about 1mm each side which was a challenge with Ti though my dremel did its work. I also modified the Brompton dropout washers/lugs to help maintain the secure wheel fixings.
PS This rides unasisted much better than my 14Kg steel Brompton conversion and even that is light by most conversions I have seen!
