The announced accessories are I think mandatory for a successful business with a folding bike which for most users is a utility bike.. Its I think a big part of the Brompton success together with the compact quick fold and good riding performances (for a utility bike).

Yes, I think the Velogical rim dynamo is the only possibility to have a powerful lighting.without the hassle of a battery system unless SON would make a specific Helix lefty hub dynamo (it exists for some trikes and for the Toxy ZR recumbent). With the Velogical rim dynamo, it is possible to have a powerful infinite lighting for about 150g.
