Was riding my Speed P8 for errand work and next thing I know the chain falls off on a normal shift and the plastic outer chain guard fell the heck off the bike. Every one of the 5 securing points broke. Visual inspection revealed that two of the screws were missing and a couple more loose.
Check your chainring guards on yer dahons.
Took mine to the shop where I bought it and they said it'd be good to go in a week and they'd go over the whole bike. I'm traveling for a week or so, so that is perfect. Besides, it's not like I don't have other bikes to ride.
