I ride a Dahon folding bike regularly. However, the factory wheels have been problematic. Every few months I break a spoke. I'm no spring chicken, mind you. Total weight including baggage in the morning is under the 105kg specified max for Dahon bikes, but not that much under!
So, I tried to find a solution. And I think I may have found one. Paul Hewitt Cycles. They have a great reputation for wheel building. I sent them my Dahon wheels and for a reasonable fee, they serviced and re-built them for me. Apart from spokes and bearings they re-used all the parts that I sent them. Yes, a re-cycled cycle wheel.
I've been riding it for about a month and it has been superb. No broken spokes. Also, an improvement I didn't expect - a more planted assured feel to the ride! Highly recommended.
