I was intimidated by my Cyclo when I first got it, but it's really simple to take apart and put back together. The spring is low tension, and it's all very logical.

That said, I picked up an early 1960s-era Svelto I swap in when I need reliability. It's not as pricey as a Gran Sport, but it's a simple little cool bit of engineering. And at $20, it was a hellava lot cheaper than even the Cyclo.
