Just found this thread today. Very satisfying build on many levels, thank you for sharing it. We have a Dutch bike we got for my wife a few years ago, an Alta or Altra or something like that. It's a single speed w/ coaster brake, like an omafiets. I don't have any pics of it. She didn't love riding it. I'm not sure what to do with it now, nobody here wants bikes like that. It's a little big for her, I thought about keeping it for myself, it doesn't bother me that it's a step through frame. But I'm not crazy about the coaster brake either. And my daughter lost the key to the frame lock, I had to destroy it to remove it. It's a real nice bike, also has a bottle dynamo. The wire was disconnected by the previous owner, I never hooked it up to test it. Thanks again for sharing the build. I scanned through it quickly but will enjoy a closer read.
