Frame construction
The Body-Solid ESB150 features a durable frame made of thick steel tubing, with precision-machined welding points. 
The bike is designed to withstand high-intensity spin workouts and even fit the standards of a commercial club. Its front fork is slightly curved for improved sturdiness.
The bike’s seat upright tube is connected to the main frame tube by a small, horizontal bar which can serve as a step-up bar, as support for stretching, or for a variety of spin workouts that require to repeatedly step-on and step-off the bike. Not all spin bikes have this feature, which is quite a plus.
The main frame of the bike features a non-corrosive and chip-resistant paint finish, black in color. The handlebar post, the seat post, and the flywheel are chrome plated. Despite the finish rust resistance, the bike is for indoor use only. If used or stored outside, moisture may eventually corrode other parts, such as the screws and bolts.
This Body-Solid exercise bike is not an extremely large fitness machine. With all the parts assembled, it takes approx. 43″L x 20″ (109 x 51 cm) of floor space. The recommended usage area for it is 72″L x 36″W (183 x 92 cm).
Although it’s not a very large unit, it is fairly heavy. Its net weight is approx. 117 lbs (53 kg) which is considerably more than the weight of the average mountain bike (approx. 3 times more). All this weight plays an important role in its stability. However, the unit is not too difficult to relocate, as its front base is equipped with two large wheels.
Last but not least, the bike’s bases feature large stabilizers. They’re all adjustable, which means you can perfectly level the bike on any type of floor. They’re also equipped with large rubber pads which deliver an excellent grip on the floor.
Seat and handlebars
The Endurance ESB150 indoor cycling bike comes with a premium spin saddle that has extra cushioning in its rear part,
and a longitudinal groove for extra airflow under the user. Its top is double-stitched and reinforced with synthetic material panels. It also has a standard design, which means you can easily find a replacement for it if needed.
The seat is four-way adjustable (front, back, up, down). It also allows a bit of tilting back and forth, if necessary. Its horizontal slider offers a few inches of adjustment, while its upright adjustment bar has multiple adjustment positions. Therefore, the bike can accommodate users between 5’0″ and 6’5″ (153 – 196 cm).
The bike’s handlebar is also four-way adjustable, just like the seat. Its upright adjustment bar offers 5 positions, while its horizontal slider offers approx. the same adjustment span as the seat. The handlebar features a multi-grip design, with a long, loop aero bar in the middle. It’s fully covered by a layer of rubber foam material, to provide a secure grip and optimal comfort.
Resistance system
The Body-Solid ESB150 indoor cycling trainer features a standard caliper brake equipped with two lateral felt pads 
and connected to the tension dial on top of the main tube of the frame. The resistance system is manual. Therefore, you don’t have to connect the bike to a power source. In order to adjust the resistance, you simply turn the tension dial, which enables the brake to add or reduce friction.
There are not tension settings or “clicks” specified on the tension dial. You simply tighten it until it generates the adequate resistance for your workout. As a general idea, you can tighten the brake up to the point you can barely pedal.
A small lever is attached to the tension dial and acts as an emergency brake. By pressing the lever down, the brake will instantly tighten at maximum stopping the flywheel. This may be necessary as the flywheel continues to spin for a while after you have stopped pedaling, and does deliver a consistent momentum.
Drive system
This Body-Solid exercise bike uses a belt drive system; it integrates a heavy-duty v-grooved belt concealed 
by an ABS guard. Since it’s a belt drive system, it comes with a series of advantages. First of all, the pedaling motion is quite smooth as a belt generates less vibration than a chain. The pedaling motion is very quiet, and on top of that, it doesn’t require any lubrication.
As we’ve mentioned above, the bike’s flywheel is designed for a consistent momentum. It weighs 40 lbs (18.1 kg), and it’s perimeter-weighted, delivering an aggressive inertia and a smooth pedaling motion. It’s also bi-directional. Therefore, you can pedal in reverse if you want, in order to diversify your workout.
The bike is equipped with a heavy-duty, 3-piece crankset which is designed to support the entire weight of the user. In other words, even if you’re close to the maximum supported weight of the bike (275 lbs), you should still be able to pedal while standing up.
The included pedals are made of metallic alloy. They don’t have SPD elements for spin shoes, but they do have toe cages. Their threads are standard, though, so you can easily find replacements for them if it’s the case.
Assembly and Maintenance
The core of the bike comes pre-assembled. Therefore, you only need to attach the base bars, the seat, the handlebar, and the pedals. This shouldn’t take more than 20-30 min. All the necessary schematics and instructions for assembly are covered by the manual. A basic toolkit is also included.
Maintenance doesn’t require much. It’s only recommended to periodically check for loose bolts and parts, and re-tighten them if it’s the case, to prevent accidents.
