i got the Vitesse D5 earlier in the year.
in just a few months of riding, i already have a broken magnet (that helps keep the bike together when folded), and a broken crankarm and pedal.
and this is just from commuting 5-6 miles each direction 2-3 times a week. no crashes or abuse either.
so, i had to take it in to the shop to get the crankarm\pedal replaced. it's now been there 3 weeks because dahon still hasn't shipped the part.
i was willing to live with the sketchy handling, the heaviness, and the annoyingly upright position but not broken components and poor customer service.
if it's this bad after only about 200 miles, then i'm afraid what the future will hold. no more dahons for me ever.
