Great the 2nd time!
I had an FX-1 for about 7 years but had to sell it because of a very long distance move. This bike is the same except for the addition of disc brakes which seem to be better. Overall it is a comparable replacement to my old bike which I loved. I highly recommend this bike.

Yes I would buy this bike again and recommend it to a friend
Overall bike is great. Enjoyed the first ride everything was going smooth until I got a rear flat tire from a little metal piece. So I decided to upgrade tires and got AW3 hard case lite tires put on it.

Absolutely love my bike!
I'm really enjoying my bike! I've had it for about a month now, and bought it as I'd been riding more and more and wanted a bike more suitable for how much I was riding.

I ride it 3+ times a week for short 5-10 mile rides in the evening, and longer 20-40 mile rides on the weekend. So far my longest ride on it was 45 miles and the only thing to have made my ride more comfortable was to have worn my padded shorts! I find it extremely comfortable to ride and the saddle that comes with it works well with my body.

I really like the disc brakes and I'm glad I bought the fx1 with disc as it's made me more confident riding knowing I can stop when it's wet.

Loving my bike, and I can't wait to get home tonight and have a quick spin.
