Frame construction
The MBH KD5801N features a triangular frame made of oval steel tubing for improved sturdiness and aesthetics.
The tubes of the main frame are double-coated with a durable paint finish, black in color, this being the only color available for this indoor cycling bike. Exceptions are the seat tube, the handlebar tube, and the flywheel which have a chrome finish.
The bike also integrates several plastic parts. However, their role is only protective or cosmetic, so they don’t play any role in the bike’s overall sturdiness. The most notable ones are the belt guard, the two side panels of the flywheel, the brake guard, and several other small covers and tube caps.
Like most other spin bikes made for home use, the MBH KD5801N bike is not an exceptionally large fitness machine. It is approx. 41.3″ (105 cm) long, and 21.7″ (55 cm) wide. However, it’s recommended to allow at least two feet of clearance all around the bike for easy access and safe usage.
Another important feature that we must mention here is the step-up bar. This is the small horizontal tube at the base of the seat tube. This not only can provide support for certain exercises or routines of various spin workouts, it also improves the overall sturdiness of the frame.
Last but not least, the bike is fairly heavy. Its gross weight (packaged) is approx. 94 lbs (42 kg). Therefore, its transport may require two persons. However, once the bike is fully assembled, it can be moved with ease via the two wheels integrated into the front stabilizer.
Seat and handlebars
The saddle included with the MBH KD5801N is a pretty standard one. It is built on a nylon or thermoplastic shell with 
a high-density foam cover. It is contoured for a better positioning and has a collar-type attachment system. This can actually be a plus if you will ever want to replace it because it renders it easy to remove and compatible options are available in most bike shops.
The bike’s seat offers four-way adjustability (up, down, front, back). Its upright post offers approx. 8.6″ (21.8 cm) of adjustment; the maximum recommended inseam for this bike is 35″ (89 cm), so the bike should be able to accommodate users up to 6’4″ (193 cm) allowing a complete leg extension. Also, the horizontal slider of the seat adds approx. 3″ (7.6 cm) of front to back adjustment.
The bike is equipped with a multi-grip handlebar. It features a loop aero bar in the middle and its side handles offer the possibility to adopt a climbing grip and an off-road grip. The handlebar is fully covered by a layer of rubber foam material in order to provide a comfortable and secure grip.
The bike’s handlebar does not have pulse sensors. Also, as opposed to the seat, it only offers vertical adjustment; it does not have a horizontal slider. Its post has several adjustment positions and offers an adjustment span between 41.7″ and 46.5″ (106 – 118 cm).
Resistance system
The MBH KD5801N indoor cycling bike is equipped with a manual magnetic resistance system. It does not have
an internal motor, which means it does not adjust the resistance automatically. Also, you don’t need an adapter or a power cord for it.
The bike’s resistance system consists of a magnetic brake placed above the flywheel and connected to the tension lever on top of the main tube of the bike’s frame. By moving this lever, the space between the magnets and the flywheel changes, which results in an increase or decrease of the pedaling difficulty.
There are several advantages to this type of resistance. First of all the magnets do not touch the flywheel. Therefore, there is no friction, the pedaling motion is very smooth, and the spinning of the flywheel generates almost no noise. Second of all, since there is no friction, the brake does not require lubrication and you’ll never have to worry about its replacement.
The brake has 5 distinct levels of adjustment. The first level provides a fairly light pedaling difficulty, great for muscle toning or workout warm-ups. The 5th tension level delivers considerably more resistance, simulating a hill climb.
Drive system
The MBH KD5801N exercise bike is equipped with a belt drive system. The exact specs of the belt are not specified, 
but it’s a poly-v rubber belt highly resistant to stretching and abrasion. As opposed to a standard chain drive, the belt doesn’t need any lubrication, it cannot catch rust, or have problems like chain link stiffening. It also generates less vibration than a chain.
The bike integrates a chrome-plated flywheel with ABS side guards. It is not a super-heavy flywheel like the ones in commercial spin bikes; it weighs only 15.5 lbs (7 kg). However, it is perimeter-weighted for a superior momentum, so it should provide at least 35 lbs of inertial weight.
The flywheel is bi-directional. In other words, you can pedal in reverse on this bike. The resistance remains unchanged when you pedal in reverse, depending on the selected tension level. It’s also important to mention here that you cannot coast on the bike.
The bike features a sturdy crankset with flattened and painted crank arms. The Q-Factor of the bike (spacing between the crank arms) is not exactly the narrowest but not the widest either; it is approx. 200 mm. The pedals are made of metallic alloy. They do not have SPD clips for spin shoes but do have toe cages. Their threads are 9/16, so if you will ever want to replace them, compatible options are widely available.
Bluetooth connectivity and other accessories
As we’ve mentioned above, the MBH KD5801N indoor cycling bike does not come with a fitness monitor. However,
it has an integrated Bluetooth module and you can sync it with your phone via the MBH Club app or the Zwift app. These apps are available for both iOS and Android devices.
The MBH Club app is free. It shows several workout metrics such as speed, distance, and calories burned. It offers the possibility to set goals for your workouts and also keep track of your workout history. It also indicates heart rate, but the bike does not have pulse sensors.
The Zwift app (shown in pics here) requires a paid subscription but comes with a free trial. It offers considerably more than the MBH app, though. For example, it offers a virtual track similar to a video game, and you can compete either with the computer or other cyclists. The speed of the on-screen character syncs with your pedaling speed. The app also offers a wide array of workout metrics, workout summaries, and the possibility to track your progress online.
Other notable accessories included with the bike are a device (tablet, phone) holder and a bottle holder. The device holder is attached to the handlebar and should be able to accommodate any tablet. The bottle holder attaches to the front fork of the bike (on the right). It’s made of a flexible polymer and should be able to fit a wide array of hydration bottles.
Assembly and Maintenance
The main body of the bike comes pre-assembled; the flywheel, the brake, the belt, and the crankset are already attached. You only have to add the two base bars, the pedals, the seat, and the handlebars. This shouldn’t take more than 30 minutes. A basic toolkit is included and the manual provides clear assembly instructions.
For maintenance, you only have to keep the bike clean and wipe the sweat that may fall on the frame at the end of each workout. The drivetrain and the brake do not require lubrication. It is also recommended to periodically inspect the bike to make sure that all the moving parts still function correctly and all the bolts still hold tight in their places.
