I have a M250 tandem, the front bottom bracket is super creaky and the chain is loose. there are two adjuster bolts on the bottom to tighten the chain; one of the bolts broke off in the frame as soon as I attempted to loosen it. Now, I cant adjust the chain and will have to get the bolt out. I contacted the factory and they sent me a youtube video on how to drill and tap a hole, no other support. This bike has less than 200 miles on it. I asked for an additional battery to offset the cost of a bike/machine shop repair bill to fix the issue, they offered a couple of bags as a "gift". I don't need a bag for a $3,300 bike I cant ride. Anybody else have similar stories of this kind of service? The bike is cool but I think its made up of cheap parts and they blame anything on the owner.
