I didn't want to Frankenstein together a bike for my wife, so I got one online and put it together this afternoon. I learned a few things.
1) The bike is too big for her at 57cm(she is 5'9"), but it is fine for me.
2) Presta valves are a thing.
3) Hauling a child comfortably will require more gears.
4) This is a pretty good single speed. I was pleasantly surprised that it was geared fairly high.
5) It was not relaxing or very comfortable to ride, though 5 miles in 20 mins was nice.
Well $55 for shipping and a probable 50% the cost of the bike for a return(since we tried it) means that I have a new bike! Any saddle recommendations? The stock model is going to have me limping.
