That's interesting that your dad didn't "get it." I'm not entirely surprised. I think all bikes have a unique purpose that makes them different and special from the others. Some people (even bikers) don't get my need for 5 bikes. They all have a purpose and are used for diff. things (TT bike for racing, touring bike for tours, mtn bike, and grocery store/errand bike and one garage sale bike that sits on the trainer year round).
I think folding bikes are just about the coolest. Fold them up and take them literally ANYWHERE. I know a man who exclusively rides is Bike Friday EVERYWHERE (touring, commuting, organized rides). He loves that bike.
I didn't realize your bike didn't come with QR wheels. That would be trickier for changing flats, although not entirely impossible.
I hope you have such a great time on your new ride. It's a great addition to the stable.
Sorry this was so long-winded.
