Considering a Folding E-Bike

[Tenkaykev]

I've not come across MK2 Electric before, how does it differ to the one I am considering?

As far as I am aware, the MK2 doesn't exist. I'm hoping / expecting that Brompton is developing a new power train using the experience and data gained from the existing customer base. They may of course have been making subtle changes to the existing electric model, I expect a few tweaks to have happened since the bikes were first introduced. I know the motor was designed with the help of Williams, working within the constraints of the bikes geometry, but I don't know of any " tear down " of an existing unit.
I can see a time when I purchase an electric Brompton, just not yet.

I know the motor was designed with the help of Williams,

I suspect marketing bullshite.

The motor, or one with an identical appearance, was in the original equipment catalogue of a German supplier.

After at least five years of thinking about it, all Brompton could come up with was a basic battery in bag front hub drive which had significant reliability problems.

Incompetent hardly begins to cover it.

if you haven't already have a look at Kinetics they do lots of custom builds.
