Circuit Fitness AMZ-594U Upright Bike Review

Circuit Fitness AMZ-594U Overview

When looking for a piece of exercise equipment, you generally want some gear that is worth the price. Many bikes have a tendency to be priced a bit higher than what they actually deliver to the home. We’ve been going through and trying to check out which of these upright exercise bikes are worth their prices and which ones really aren’t. Today’s subject for study is the Circuit Fitness AMZ-594U Upright Bike. This bike falls into the middle of the pack in terms of price, but that’s a crowded zone. It’ll have to provide some really promising features if it wants to stand out. We’ll be checking out the electronics, resistance and general build of the it all before comparing that to the prices that are asked for it. So with all of that out of the way, let’s hop right into our review of the Circuit Fitness AMZ-594U upright bike!

We’ve mentioned the price of the Circuit Fitness AMZ-594U a couple times already, so it only makes sense to start here. After all, many people base their selection of these stationary bikes with their budgets. The Circuit Fitness AMZ-594U upright bike ranges between $300 to $430, depending on where you purchase from. Like we said, it is the sort of middle of the pack in terms of price. However, it is not anywhere close in regards to the warranties that come with it. You only get a 2 year limited warranty on the frame of the bike. No warranties come with the parts, the electronics or the labour. This is pretty atrocious and fits more with a bike that costs half this amount. If something does go wrong with anything but the frame, then you are out of luck. Payments and replacements will have to come from your end. It’s pretty darn poor. There are also complaints about the customer service being almost nonexistent, which is never a good sign. But we’ve got to move on, else we’d be complaining about those lack of warranties all day. The shipping process shouldn’t take longer than 1-2 weeks. Once it arrives, the assembly process should be fairly simple. It should only take about an hour to put together thanks to the straightforward assembly process. Even those who aren’t particularly skilled should find it an easier process than they might be expecting.

Many of the top modern upright bikes include excellent monitors that can revolutionize your experience onboard. While the Circuit Fitness AMZ-594U upright bike’s monitor might not do that, it certainly performs admirably. It has a fairly small LCD screen that is backlit, allowing you to see in darker settings. It will display statistics like your time, distance, RPM, speed, watts, calories, and pulse. These can be seen in either metric or English measurements, which is always a nice feature. There aren’t any Bluetooth functions here, so in order to get those pulse readings, you’ll need to hold onto the pulse sensors of the handlebars instead of connecting to any sort of chest straps. You do get 15 preset workout programs to help add variety to your workout. These programs are divided into “Beginner”, “Advanced” and “Sporty” categories, which should generally tell you the sort of level that they are aiming at. You also get bonus Recovery and BMI functions, which are nice additions to see. These all come together to make a monitor that won’t break any records, but will certainly add to the experience.

The resistance of the Circuit Fitness AMZ-594U upright bike is another key factor that you should consider. The resistance system onboard the is an automatic magnetic one. This does mean that you have to plug the bike into an outlet in order to get the resistance. The magnetic system combines nicely with the poly-v belt of the drivetrain in order to create a nice, quiet and smooth workout. Even late night workouts shouldn’t really wake anyone up. You have 24 different resistance levels to pick from, which is a nice selection. This gives plenty of room for dialling in exactly what sort of resistance you want for that workout. The upper levels will also provide you with a fair bit of challenges. The crank of the bike is a 3-piece one. This is quite good, as they are always superior to the 1-piece cranks. There are a couple of bits that we don’t have the information for. The specific flywheel weight is not given, nor is the Q-Factor. For those who are unaware, the Q-Factor is the distance between the pedals. If it is too wide, you can get rather uncomfortable. If it is too narrow, the same can happen, as well as injuries. However, there aren’t really any complaints for either user reviews or official ones, so it doesn’t seem to be too big of an issue. Meanwhile, for the flywheel weight, it doesn’t seem like it could weigh more than 20 lbs (9 kg) based on the weight of the rest of the bike.

Speaking of that weight, let’s examine the rest of the physical footprint of the Circuit Fitness AMZ-594U upright bike. It has a total weight of 79 lbs (35.8 kg) and can hold a maximum weight of 300 lbs (136 kg). It specifically measures out to be 37.5 inches (95 cm) long, 22 inches (56 cm) wide and 54 inches tall (137 cm). There are small stabilizers on both ends of the bike in order to keep you steady on uneven floors. However, they are not the largest and most stable, so you might still feel the occasional bit of rocking back and forth. There are also small transport wheels on the front of the Circuit Fitness AMZ-594U upright bike in order to help with mobility around the home. They aren’t the biggest wheels in the world, but they at least work. The frame of the bike is a pretty standard steel one.

We are going to finish out with the rest of the physical elements of the Circuit Fitness AMZ-594U upright bike, starting with the handlebars. The handlebars are multi-grip ones and can be adjusted in regards to their angle. But they cannot be adjusted vertically or horizontally or anything like that. We already mentioned the pulse sensors that are available on the handlebars, but that’s about all the features you’re going to get. They are covered with rubber in order to provide comfort and generally do a good job of this. The saddle of the Circuit Fitness AMZ-594U upright bike is adjustable both vertically and horizontally, which is always nice. It means that more people of different sizes can fit comfortably onboard. The seat does seem to fall victim to the problem many exercise upright bikes share in that it isn’t very comfortable. Of course, this can be fixed with a cushion or even a new seat entirely, The saddle tube is pretty darn thin, so you might find some rocking around on the more intense workouts. The pedals are absolutely nothing special outside of the adjustable straps that they’ve got on them. This isn’t too surprising and actually par for the course. As for any bonus features that you might get with the Circuit Fitness AMZ-594U upright bike, you can use the tablet holder above the monitor for entertainment. Then there is also a water bottle holder on the same console for some rehydration. You’ve even got speakers on the monitor that you can plug in your phone to and listen to music while you cycle.

Circuit Fitness AMZ-594U Upright Exercise Bike Pros:

  • A wide variety (24) of resistance levels
  • The magnetic resistance and belt drive make for a quiet and smooth workout
  • The seat is adjustable both vertically and horizontally
  • The handlebars are angle adjustable and have pulse sensors
  • The monitor has 15 preset programs to add variety to your workout
  • There are transport wheels for mobility and stabilizers for… stability
  • Monitor will display a good variety of stats in both metric and English measurements
  • Bonus features like the speakers, media tray and water bottle holder are good
  • 3-piece crank is always good

Circuit Fitness AMZ-594U Upright Exercise Bike Cons:

  • Awful warranty package
  • The seat can get rather uncomfortable
  • No sort of Bluetooth or online connection from the monitor
  • Floor stabilizers aren’t the most steady
  • Reports of horrible customer service are not appealing

The Final Verdict

The Circuit Fitness AMZ-594U upright bike is a solid option for anyone who is looking to get a home exercise bike. It offers a decent amount of workout challenge and variation through its monitor and resistance combination. It does lack some higher quality features like online connection and a comfortable seat. Perhaps the biggest sin that it commits is having almost no warranties with it at all. This makes the price a lot more suspect, as you could go get one of the Nautilus exercise bikes (the U616 model) for a similar price and get more. In fact, we’d still probably recommend that bike over this one. But if you are absolutely determined to get this bike, there are still good elements to be used here.
