Tons of features

I'm loving it so far! I've used this bike for 2 weeks and don't have any problems so far. Price was decent when compared to others online and it came with a lot more features than I expected like heavy flywheel, high weight limit, pulse readers, and tracks cadence.

Exactly what I needed!

The quality of this bike really exceeded my expectations. It's heavy, sturdy, and very quiet. I'm 5'9 300 pounds and have no problems riding this beast of a bike. The seat took some getting used to but feels better after a couple rides in. I highly recommend this bike!
