It should come standard with the bike so having to pay extra is a little annoying but it gets the job done. Haven't had any issues with screws coming loose or any parts breaking but could definitely be better built if you're going to be asked to pay for it seperately.

A nice inexpensive option for anyone that wants a no-frills scale. It's not the best built machine by any means, but that's to be expected at this price point. It comes with mounting hardware to mount the screen to a wall, but the cord is a little too short for taller folks. Overall a good buy!

A great inexpensive rechargeable dynamometer you can get relatively quickly if you want one. Is it accurate? We may never know. But is it fun to have laying around? Absolutely.

If you have the space, this is possibly one of the best cardio machines you could add to your gym. i spent years on the original chain-drive air bikes and after using this once, I won't be going back if I have the choice. The belt drive system eliminates almost all coasting so you're forced to keep the pedals moving if you want to keep the calories/distance moving up. The only downside I see with the belt drive system is you can't manually adjust the resistance like you can with other bikes but I think that helps keep you honest.

In my opinion, the wind guard is completely necessary if you're in a colder gym or riding for a longer time. It's easy to install and remove so you can choose if you want a little extra wind on your face.
