The Brompton has a narrow hub so they make a specific kit for it.
Have you emailed them to double check?
I have messaged them a few times over the last couple of days and they’ve been very helpful!
Hi.
My understanding is that the measurement between forks is 63mm width. The following information is copied from email swytch sent me yesterday.
"Universal motor = 100mm width, for all regular bikes and some folding bikes
Brompton (narrow) motor = 74mm width, for narrow forks of 70-80mm width, such as Dahon folding bikes".
So if I'm understanding it correctly that means my forks are at least 9mm width to small.
The FORK is
Suntour NRX D LO, 700c 63mm QR lockout.
I will definitely double check with swytch on the comparability. So thanks for your help.
