The bright side: I used it happily, almost daily, for 3 1/2 months before it broke. That ends up costing $40/month, which is cheaper than a gym membership. Plus, it got me through the rainy months. Now, we'll both go outside: me to jog, and the bike to the garbage.Like others said, it started dropping black shavings; then it squeaked; one day, it just seized. I took the casing apart and loosened some bolts, but there are so many broken parts (ripped belt, destroyed plastic), it's not worth any more of my time.I will miss it. But I will buy a better one next time.I wonder why this bike has so many positive ratings--either they were written during the three-month honeymoon phase (the length of the return policy), or the writers didn't ride it long enough to find out.Amazon is good for books. Not for bikes.
