Exactly the same for me bromptonfb. I fitted mtb pedals after the folding ones got crushed. I'd have rather sold them on
eBay for near the extortionate price Brompton charge.
The rack is in the balance I think, for some it's worth it others can't understand that point of view.
I can't understand how people ride with the original triangular wheels unless they ride funny, putting far too much pressure on their knees, or by cycling with their legs wide apart and feet on the edge of the pedal... again damaging their knees. I suppose they could have no nerves in their adamantium ankles...
Dynamo: How much night riding are you expecting to do? If regular I think they're a must. If very occassional or not at all, obviously you don't need it.
