We have Keiser spin bikes at my now former gym. They're smooth for sure, but they're not as adjustable as other brands. I always felt too stretched out on it. Plus, they had built-in power meters on them. Now, I'm sure some really like this, but I found it both distracting and discouraging. There were always people in class yaking about how much power they could generate. It was hard to tune it out. I have a spin bike at home that's more along the line of a Johnny G spinner. I really like it.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
