BO15 Frame Construction
The Efitment B015 features a V-frame made of steel tubing with a low center of gravity, which results in superior stability. The bike’s weight of 73.4 lbs (33 kg) and adjustable base stabilizers also improve its overall stability.
The bike’s frame features a black powder coating resistant to abrasion and corrosion. The only exceptions are the seat and handlebar tubes, which have a chrome plating finish. Of course, the covers of the belt and flywheel are made of sturdy ABS material.
The fully assembled unit is not extremely large. It is only approximately 43.5″ (110 cm) long and 21″ (53 cm) wide. However, it is advisable to leave at least two feet of clearance all around it for safe access and operation.
The fully assembled unit is not extremely heavy; it weighs approximately 73.4 lbs (33 kg), considerably less than other heavy-duty spin bikes. But it still weighs more than twice the average road bike’s weight, so its assembly may require two people. However, once assembled, its relocation incorporates the small wheels into its front base stabilizer.
The Efitment B015 upright exercise bike includes a standard saddle slightly wider than the average spin seat. It does not integrate extra cushioning, but its top is high-density foam designed to provide optimal comfort.
The seat attachment system involves a triangular metallic plate; it attaches to this plate via three screws. Therefore, you may have to improvise to replace it with a different bike saddle with a collar attachment system.
But the seat is reasonably durable, delivers a pretty decent comfort, and you can improve its comfort by adding a gel seat cover if needed.
The seat offers four-way adjustability (down, up, backward, and forward). Its vertical post has six adjustment notches and offers approx. 5″ (13 cm) of adjustment for users with an inseam between 23″ and 28″ (58 – 71 cm). However, its horizontal slider also offers a few inches of front-to-back adjustment.
Therefore, the bike should be able to accommodate users between 5’0″ and 6’3″ (153 – 188 cm) with no problem, allowing a complete leg extension during pedaling and a satisfying range of motion. In addition, the bike has a user weight capacity of 242 lbs (110 kg), so the seat should handle users up to this weight with no problem.
This Efitment exercise bike has a multi-grip handlebar. It offers the possibility to adopt a standard grip, a parallel grip, a racing grip, and a few others. A layer of high-density foam fully covers it to provide a comfortable and secure grip.
The center transversal bar of the handlebar assembly features a set of two stainless steel pulse sensors. Thus, the unit’s fitness monitor can track your pulse if you hold on to them.
In terms of adjustability, the handlebar only adjusts up and down. In addition, it does not have a horizontal slider like the seat. Instead, its post offers several inches of adjustment.
The Efitment B15 indoor cycling trainer has a manual magnetic resistance system. Therefore, its braking system does not have an internal motor, and the bike does not require an external power source. Also, the console plays no role in the resistance adjustment.
The bike’s resistance system consists of a magnetic brake placed close to the flywheel and attached to the lever on the bike’s front tube. As you press the bar down, the brake moves closer to the wheel, which increases the intensity of the created magnetic field. Thus, it ultimately leads to increased pedaling difficulty.
The bike offers eight levels of resistance. The first level is excellent for anyone who requires recovery training or, in general, light workouts. However, the 8th level does provide quite a bit of difficulty, simulating a steep climb.
Like most other exercise bikes with a magnetic resistance system, the Efitment B015 features a belt drivetrain. It uses a poly-v rubber belt, delivering a smooth and quiet pedaling motion. Unlike a chain drive, it saves you the hassle of periodic lubrication. Also, it generates less vibration than a chain drive.
Compared to most indoor cycling bikes with a friction resistance system, the B015 has a balanced flywheel, not a perimeter-weighted one. This flywheel weighs 17.6 lbs (8 kg) and provides consistent momentum. It’s also bi-directional. Therefore, you can pedal in reverse if you want.
But when pedaling in reverse, the bike retains its resistance. In other words, when pedaling backward, you will benefit from the same resistance as when pedaling forward, depending on the level selected by the lever. Also, when pedaling in reverse, the console still tracks your workout metrics.
The bike has a heavy-duty crankset featuring steel crank arms and metallic alloy pedals. Therefore, as long as you don’t exceed the specified 242 lbs (110 kg) weight capacity, you should be able to stand on the pedals with no problem.
The pedals don’t have SPD clips for spin shoes but have toe cages with adjustable straps. In addition, they have a non-slip design with side lugs. Their threads are standard 9/16, so compatible options are widely available if you want to replace them with SPD or other pedals.
BO15 Fitness monitor
It’s a basic fitness monitor featuring an LCD that can track time, distance, speed, calories, and pulse. Unfortunately, it does not have preset programs, nor does it has any online capabilities. It uses two AAA batteries as a power source, and it starts when you pedal and turns off automatically after a few minutes of inactivity.
The monitor features three buttons: Set, Mode, and Reset. The Set button allows you to select a target value for time, distance, and calories. When you choose a goal target for one of these metrics, the display will show the remaining amount until you complete the goal.
The Mode button allows you to scroll through the workout metrics and select the one you wish to view. You can choose the SCAN mode, and the console will rotate all the workout metrics, showing each one for a few seconds. The Reset button clears all the values on the monitor to zero.
Pulse Reading and Heart Rate Zones
The monitor has a pulse reading function, but it is not telemetric. Therefore, it can only read your pulse if you hold on to the sensors integrated into the handlebars. Unfortunately, it does not work with Polar or wireless HR chest strap transmitters.
The fitness monitor integrates a tablet holder. This accessory is above the LCD, so if you put your phone or tablet on it, it won’t block the view of your workout metrics.
The top section of the monitor features a grid with the heart rate zones. It would help if you aimed to benefit from a better aerobic output, fat burn, etc. However, as many other machines only show this grid in their manuals, this is a plus, so you usually don’t have it when exercising.
BO15 Assembly and Maintenance
The most important parts of the bike come pre-assembled. In other words, the flywheel, the belt, the crankset, and the brake system are pre-assembled into the mainframe. Therefore, you only have to add the base bars, the seat post, the handlebar post, the seat, the handlebar, the fitness monitor, and the pedals.
Consequently, it shouldn’t take more than 30-40 minutes. All the necessary tools for the task come with the bike, and the manual provides clear instructions and schematics.
Maintenance does not require much. It is advisable to wipe any sweat that may drop on the frame at the end of each workout. The internal parts don’t need any lubrication. You should also periodically check the bike for loose bolts or broken parts and re-tighten or replace them.
