Our Rating

Rating: 82/100. So what do we think of this bike? It has good and bad points. We like that the bike comes with a sturdy build. It has a 2.5mm tubing frame and linkage arms that have rotational bearings. It also has all metal fan blades, which is going to give the best overall riding experience possible.

In addition to that, it also has a 350lb. user capacity, which is high and demonstrates just how solid this one actually is. A lower user weight capacity is a giveaway that the bike may not be as well built as it claims.

The frame on this bike is heavy duty at 125 lbs., which is higher than most other bikes on the market of a similar nature.

With a 24-foot resistance fan, you’ll naturally stay cooler while riding this bike as that fan is going to make some wind. It also allows you to have a maximum amount of resistance if needed, therefore you can be sure you’ll feel fully challenged when doing your workout session.

What we really like about this particular air bike is that the chains that typically require lubrication have now been replaced with an automotive grade silent drive belts. This means that you’ll have no worries about dealing with maintenance. Before you would have to lubricate those chains every so often, but this is no longer a requirement. This makes the bike exceptionally easy to have and use, so it shouldn’t give you any sort of issues in the long run.

This is good, because the lack of warranty is definitely cause for concern. While most people should feel quite confident still going ahead with their purchase, know that you aren’t covered should anything break down.

Just by looking at the build though you can see the commitment to workmanship and quality that’s been put in, so this should help give you some peace of mind.

The fan on this bike is also heavy duty at 24’ and will supply you with variable resistance depending on what you set it at. This helps ensure that you continue to see good progress with your workout programming.
