If I were specifying dynamo lighting on a Brompton now, I'd want the Shutter Precision hub. Not sure if they offer that as an option yet? (Not that it matters, if it's perpetually out of stock.)
They don't offer *any* generator hubs as an option now, but the SP hub kit from 2018 is still available elsewhere.
When they run out, it's going to be a matter of working out which B&M lights won't foul the luggage block and getting a wheel built.
I suppose they didn't sell enough to make it worth while, though I'm surprised. Having lights always available is perfect on a bike like a Brompton, and a small percentage of the price when you're spending £1,500 or so on one.
As SP made variants of their efficient hub generators for Brompton, hopefully they will continue and people can have their own generator built up by shop or self:
As for the continued availability of the front dyno lamp bracket, if not its either DIY or with riser bars, you just fit the lamp on handlebars (Perhaps Sbars could have a lamp fitted under bars if short luggage was used)...I prefer bar mount anyway as it avoids feeling the need to augment low mounted front lamp with a higher battery one on bars.
I wonder if the fitting of wiring loom etc was too slow, thus dropping dynamo systems streamlines/speeds the production line?
Anyway Bromptons dyjnamo lamp choice was a bit rubbish anyway, fitting a Spaninga solo to L-types where is blocked by rear mudguard seems a bit careless....
For battery lamps they should at least offer UK purchasers the option of a STzvo compliant Cateye GVolt instead of the plain unapproved Volts......
