This bike comes with a micro-adjustable resistance knob so that even the slightest increase or decrease in resistance are smooth and customizable.

Yes! We have a great library of workouts that you can perform on your indoor cycle, which can be found on the Workouts section of our website as well as on our YouTube channel.

A belt drive system has a belt that connects the pedals to the wheels for a smooth ride. A chain drive system uses a chain to connect the wheels to the pedals and the feeling and sound of a chain may feel similar to riding a bike outdoors.

The resistance you’ll feel with contact resistance is incredibly strong. A felt pad is used to apply pressure to the flywheel through varying degrees of contact. The resistance can be adjusted by twisting a micro-tension knob.

Feel confident sitting on our durable design with a 265LB max user weight limit.

Yes! The handlebars are 2-way adjustable (up and down) and the seat is 4-way adjustable (up, down, forward, backwards) for a fully customizable fit.

The best way to see if this bike would be suitable for you is to measure your inseam. This bike can accommodate inseams between 26.5" and 37".

This bike comes equipped with caged foot pedals that provide stability and safety.

There is a 3-year warranty on the structural frame and 180-day warranty on other parts and components.

Spinning happily at home

Fit right in my budget and came with features I was looking for specifically lookingn for like the monitor and bottle holder. Overall I'm really happy with this purchase and happier that I didn't have to break the bank for it!

I love it. Since avoiding going to the gym. Smooth ridding does exactly what I need it to do. The LCD is great keeping track of mileage calories.

This bike has been great! Since I got it I've gone on to ride almost every day. It was easy to put together and works perfectly. The resistance options are simple and east to use and the seat is quite comfortable. Mine did start to loosen after a while, but I didn't tighten it that much when I put it on because I was worried it was in the weird spot. Great bike for a casual excerciser.

New to this

I got this bike for an online spin class I wanted to take while on quarantine. Other than the seat needing to be adjusted I love this bike it does the job. I use it about 5 times per week.
