I bought my Magnum Metro last fall and have just under 800 miles on it. Last month I had a rear tire spoke break...presumably from coming off a low curb too fast/hard...at least that was the only thing I could think of....husband also has a Metro and we ride together a lot he has had no such issue. Was able to get the spoke repaired at LBS. Just had another spoke break (still TBD if its the same spoke or another). LBS said it could be a manufacturing defect and won't know until I get the bike into them. Has anyone experienced issues with their spokes?
