Reebok GB40 Exercise Bike Review

You’ve probably said countless times ‘I’ll go to the gym today’ but that never happened.

Well, that is not surprising at all and we can only think of one reason you can’t make it to the gym – you’re short on time (and you have many commitments).

If you can’t make it to the gym, the best strategy is to get an exercise bike, like the Reebok GB40, so that you can exercise on your own time and in the comfort of your own home.   

This model sets out to do a couple of things with its 9 kg flywheel, 32 levels of magnetic resistance, adjustable and well-padded seat, self-levelling pedals with straps, 5.5″ LCD screen, and some added features.

In this Reebok GB40 exercise bike review, we explore everything that the bike has to offer in detail. 

Let’s get started!

The Reebok GB40 features a 9 kg flywheel, which is relatively heavy for an exercise bike in this price range. This heavy flywheel, along with 32 levels of magnetic resistance, makes the exercise bike ideal for both light and intense cardio sessions. 

There is a 5.5″ LCD screen in the console, which lets you clearly see the metrics such as time, distance, watts, heart rate, and speed. Other features include an adjustable seat, hand pulse sensors, recovery program, transport wheels, self-levelling pedals, tablet holder, and a bottle holder.

Reebok GB40 Review: Pros & Cons


  • Easy setup
  • Smooth ride
  • Good for all levels
  • Transport wheels make it easy to move
  • Inexpensive


  • No heart rate receiver
  • No user profile settings
  • No adjustment in handlebars



Who loves a densely-padded seat? We do! The feet of the seat is the single biggest factor in the overall comfort of any exercise bike. We’re pleased that the seat in the Reebok GB40 feels comfortable for long rides. The seat is also adjustable both vertically and horizontally via a quick-release mechanism – a feature that is especially helpful for households with multiple riders. The seat height on this bike ranges from 65cm to 9m; thus, accommodating all rider heights.

Moreover, the adjustable seat is particularly helpful if you’re recovering from overuse injuries, such as lower back pain. 

While it is possible to adjust your seat height where you want it, there’s no option for adjusting the handlebars. If you need adjustable handlebars, the Reebok ZR9 is a decent option. This bike also allows you to connect to the Reebok app for more features.


The bike also features self-leveling pedals to reduce the risk of injury when putting on a lot of miles. Besides, the pedal straps keep your feet from slipping off the pedals.

The  34 kg exercise bike – which can accommodate 120 kg – is relatively easy to put together in around 45 minutes. There aren’t too many fiddly steps in the assembly instructions, but we still recommend you use an extra pair of hands to help speed things up.



The 32 resistance levels provide enough range on the Reebok GB40. And, because the bike uses magnetic resistance, it doesn’t make any noise when you ride it. This means it is a bike that you could easily use any time of the day or night.


Another area where the GB40 exercise bike could use a bit of improvement is the console. It has no heart rate receiver and no user profile settings. 

On the positive side, the 5.5″ LCD screen is clear and intuitive, and certainly all you’ll need to stay on top of your workout metrics. It displays the time, speed, RPM, distance, calories, pulse (via the handlebar sensors), and watts while allowing you to choose 12 motivational workouts + user-defined and HRC programmes. 

It is easy to see your key stats in the light, but the numbers can be hard to see when you’re riding in the dark. Keep this in mind if you are fond of late-night workouts.


The flywheel on the GB40 exercise bike is 9 kg, and this is good enough to provide a smooth feel and consistent motion while riding. We love that functionality is streamlined in the bike’s flywheel, so there’s no jerky pedal motion or pauses in the rotation. 

Other Features

Water Bottle Holder

As well as delivering complete stability, the bike also helps you get through the most intense sessions, thanks to the built in-water bottle holder.

Tablet Holder

There’s also an integrated tablet holder at the top of the console for holding any personal device securely. The unit doesn’t come with a tablet, but your own tablet or smartphone should fit here. If you want to push yourself through fitness apps or join an online workout class, this feature is a plus.

Final Verdict on the Reebok GB40 Review

Get it if you don’t care about all the fancy tech. 

As you can see, the Reebok GB40 exercise bike is not the most advanced in the Reebok range – it lacks a wireless heart rate receiver, user profile settings, and adjustment in the handlebars.   

Even so, the Reebok GB40 exercise bike has a reliable 5.5″ LCD screen that allows you to monitor the time, speed, RPM, distance, calories, pulse, and watts.

It also ensures a comfortable, stable ride. You’ll be surprised with the exercise bike’s stability considering it only weighs 34 kg. 

The 9 kg flywheel helps to create a smooth ride and is suitable for intense workouts. Even the most experienced rider will find this bike to be reliable due to the 32 resistance levels of magnetic resistance. Additionally, the Reebok GB40 exercise bike comes with a tablet holder for easy viewing of fitness classes and a holder for keeping your water bottle within reach.

If you’re someone who just wants to stay active using a quality exercise bike, this one is an excellent model for the price.
