Well, the chain doesn't seem to have a quick link so I ordered a few. Great advice. I've already added latex gloves to my kit. So I'm also waiting on new tires, Mr. Tuffys, and a tube (couldn't get the punctured one to hold a patch). Also ordered some foam blocks to protect the display and controls when the bike is flipped upside-down; I will carry these under the front rack or something. Even with a stand available, upside down low to the ground seems the way to go. At that point, with a breakable chain and protected bars, I think that repairing the rear tire on the side of the road will be theoretically possible. I have changed plenty of rear tires on non-e bikes, but this is a whole other ballgame with this heavy, tight-fitting wheel assembly. But I feel better that a solution is in my grasp. I'll post my impressions of the hopefully stouter tires once I get them. I am not a huge fan of the stock tires now that I have seen them up close; my sense is they are suceptible to flats. I'm not going to complain because there's a reason this bike was so affordable. But disregard my comments about the brakes; the rear tire might be most valuable upgrade. There are not many available, but in addition to the tires I purchased, Specialized makes a 60tpi Ground Control in 20x4. I had never heard of Vee Tire, but I found some reviews of their larger tires and they appear to have a pretty good reputation with mountain bikes.
