Exceeded my expectations.
I really didn't know what to expect, but I was pleasantly surprised at how much power it has. I believe the top speed I hit was 34 mph, and that's more than enough for me. I've put over 100 miles in just a few days and don't see myself slowing down. It's a decent workout compared to a standard bike, you just go twice as fast! It's solid and looks like a small motorcycle; great aesthetics.
I did have an issue with the screws to the derailleur protector, but they replied quickly. I feel very confident with them supporting their products.
