Introduction to the Spirit AB900 Air Exercise Bike

Just because you see the words ‘indoor bike’ doesn’t mean that you know what to expect. Like everything in this world, there’s an almost unfathomable amount of diversity and variation. Colours, dimensions, materials… these are all part of that variety, and indoor cycles are a part of this world.

You may not be able to feel uniqueness everywhere on a bike. Components like a simple control keypad, easy programming integration and dual sided molded pegs can all be very familiar, but there’s always more than meets the eye. Underneath the hood we could be buying innovative and unique interior design and engineering parts. Aspects like the jaw dropping unlimited resistance drive train and high quality bearings are often unseen, but that doesn’t mean they’re not unique.

So why do I keep talking about special items or unique values?

Here’s a breakdown of the Spirit AB900 Air Bike and what makes it so creative. From the use of an air driven resistance system in the first place to the dual targeting cardio and calorie burn design, this bike is sure to excite you, enhance your fitness, and make for a visually inviting addition to whatever room you put it in.

Let’s break down the pros, cons, specs and best features of one of the standout bikes from Spirit.

Overall Verdict:

Hopefully the specifications and features above give you a clear picture of this machine.

It looks great, is highly adjustable and has a strong user focus. It fits into most rooms well: good looks matter for home use, even in a home gym.

The energy-saving design is a bonus. It’s great to see innovation that keeps the cost to the buyer in mind. Air resistance bikes aren’t new, but they remain popular for a reason: limitless resistance and low running costs.

With easy to read instructions, easy programming integration for the console, seat adjustment speed and performance design foot pedals, this bike feels like the right choice for those seeking ergonomic workouts with the ability to push themselves if needed.

High performance seems to be a focus of Spirit. With an incredible range of high performance equipment showcased even on this site, Spirit are one of the number one manufacturers around. This brand makes plenty of good machines, so read on to see what stands out about this one. Target time, effort and distance are the obvious benefits, so let’s look at the details of the design.



What I Liked About This Exercise Bike

The anti-skid foot pedals are a highlight. This ergonomic foot pedal design helps keep you safe and secure. There’s nothing worse than slipping or bumping on any kind of equipment, so to stay focussed and unscathed this feature is a must. Speaking of frustration-free, the user comfort convenient console feedback is awesome too. The console is simple, easy to use and really helps you stay on track while you’re burning those calories and tracking that data. Yes, it’s a little limited, but it’ll never be the difference between a great workout and a bad one.

This powerful tool comes with a fairly compact design too. Good dimensions are always something to look for. If you have space for a tank, go heavy-duty, but if you want to save space, this is a good option. Saving money is also a massive plus. With no mains power needed (other than the 4 AA battery-powered console), there are no running costs, and independent and customer reviews are positive.

Last but not least, your workout intensity is completely down to you. The air-driven resistance lets you push hard. The faster I spin, the harder I work, the more I gain, and 1/8″ sturdy chain helps to support this too.

There’s no dated crank system to fiddle with mid-workout, and the resistance matches your effort. This also makes me feel really connected to the bike, and trust me, when you’re riding on these for a long time this is super important.

Let’s move on.

Things That Could Have Been Better

So this section is less about this bike’s drawbacks and more about the drawbacks of air bikes generally.

They’re pretty noisy.

While having an air bike has many benefits, especially a bike as sturdy as a steel frame one, with great maximum user weight it tends to make a lot of noise. And it’s not due to the chain power. An air bike is essentially a big fan, so if you need to be careful with noise, maybe you need to workout late at night or live next to close proximity neighbours, then you may want to consider carefully the purchase choice. Don’t get me wrong it’s not a deal breaker for most, and it doesn’t exactly sound like a jumbo jet, but you do have more noise than the usual, normal, upright bike.

What else? This next one’s a little picky but personally I prefer a higher fan blade count. The harder you pedal, the higher the resistance, so on an air bike there’s nothing stopping you working as hard as you like. You can justify this bike easily if you still want a cooler workout (although, if you really want a cooler workout, then the faster you spin the faster that fan’s blowing air and cooling you down, get to work!)


FAQ’s

Why should I care about a bike that accommodates upper body stability, bike’s aren’t for total body exercise?

Biking involves every part of your body to some degree, and if you’re going for endurance rides then physique maintenance and low strain postures are super important. Bikes that accommodate every part of your body should be a consideration – no body likes fatigue and unnecessary strain.

What is low load rehabilitation?

Low load rehabilitation is great for those who may be recovering from and injury. For example, if you’re a weight lifter but mobility is an issue, so much so that it caused some muscle tear or cartilage damage (for example), then a bike is one way to help with recovery. Low load rehabilitation to high performance is exactly what those in recovery should be striving for, and muscle repair and mobility repair need to come first.
