Congrats on the bike.
Tires should last at least 5 to 10 years on a city bike. You may want to look at Schwalbe Marathons. A bit more up front but cheaper in the long run and much less hassle with fewer flats or other problems. What went wrong with your rims? They should last 25 to 50 years. I'd certainly not replace with the same given your experience. I'd also look at some much stronger spokes if you're getting a new rim laced up on your hub. Same for the dyno, what model is it? Why do you think it needs replacing?
