I use this bike every night for the past 3 weeks. It's easy to use and feels safe. I like my HIIT workouts and can pedal while standing without feeling like the bike will fall apart on me. I appreciate that the water bottle is placed on the side so it's easy to grab my water in a non-awkward way. Overall, if you're looking for a sturdy well constructed bike, you should definitely check this one out!

The construction is impressive and not at all flimsy. I am 5'7 210lbs and have no problem riding this bike. It's sturdy and doesn't rock even with my full weight on it. Flywheel provides a smooth spinning quiet ride. Highly recommend this bike.
