Would love to use it if only they would send a replacement part.

We purchased the bike as a way for my wife to continue to exercise during her chemo treatments for cancer. When I went to assemble to bike it went together easily with the exception of the left pedal. It was clear that the bolt was stripped and it would not screw into the bike nor would the nut that is supposed to hold it on screw on. I requested a new part be sent to me as part of the warranty we purchased and it has been under review for days. It notes you can leave a claim 24/7 but says nothing about how long it will take them to agree to replace a defective part or not. All we get are emails saying it is under review or to rate our purchase. Would love to use the bike and provide another evaluation. Let's hope that happens sooner than later.

Best Indoor Bike Ever

This was the best purchase to finalize my workout room. It’s smooth, quiet, and is very stable even on carpet. I purchased the lower cost model and it has the dumbbell holder, water holder, and tablet holder which is amazing. I only added a cushioned seat cover for comfort during extended rides. It’s definitely a must purchase product for your home and is very affordably priced.

Meets my needs, exceeded my expectations

Good price, easy to put together, small footprint, very quiet. The display gives all the basic information you need and the resistance knob provides a great range of resistance. Still early, so can't speak to durability, but seems well made and should hold up for the amount I will use it. Overall, I'm very happy with the purchase.

Decent Bike

For the price this bike has been decent so far. I was able to put it together myself with little trouble. I'm a little disappointed in the quality - my bike came with stickers falling off, scratches on the flywheel, and it isn't as quiet as I expected. Overall though, I'm pleased with the bike itself and have enjoyed using it so far.

This is a smooth and sturdy ride. The assembly was not difficult and everything works as it should. High value for a reasonable price.

Disappointed in quality

The bike is much more wobbly than we anticipated. Some of the materials feel cheap. We are open to liking it, however so far it doesn't meet expectations of other units we've used in the past. We are surprised by the quality drop off from other models.
