ESB250 Frame construction

The Endurance ESB250 features a heavy-duty V-frame which offers a much higher weight capacity; it can hold users up to 350 lbs (159 kg). Its frame has a thick, ovalized steel bars, with precision-machined welding points. Its mainframe section is one-piece, the only other frame parts that need to be attached to it with screws are the base bars.

Like most commercial-grade spin bikes, the ESB250 is quite a heavy unit. With all the frames and parts fully assembled, it weighs 145 lbs (65.7 kg), which is almost four times the weight of the average mountain bike.

All this weight considerably improves its sturdiness and stability. Therefore, even if you’re close to its maximum weight load capacity, you can be sure that the bike won’t wobble or move when you pedal.

Compared to other spin bikes, the Endurance ESB250 is a bit larger. However, it’s not an extremely large fitness machine; it’s not the size of a commercial treadmill or elliptical. It takes approx. 52″L x 21″W (132 x 54 cm) of floor space. It is recommended, though, to leave at least two feet of clearance all around it for safe operation.

The bike’s frame and base bars are double-coated with a corrosion-resistant and scratch-resistant paint finish. The color used is gray, with the Endurance logo painted blue, these being the only colors available for it. The seat and handlebar posts, as well as the flywheel feature a chrome coating.

Seat and Handlebars

The Endurance ESB250 features a 4-way adjustable seat (up, down, front, back). It also allows a bit of tilting back and forth, if necessary. Its horizontal slider offers a few inches of adjustment, while its straight adjustment bar has more than ten adjustment positions.

Due to the seat adjustment system, the bike can accommodate users from 5’0″ (153 cm) and up. The seat assembly is also durable enough to hold users up to 350 lbs (159 kg).

The saddle itself is not comfortable. It does not provide for the utmost comfort. It’s slimmer than most upright bike seats. It integrates a layer of foam padding, though, which is thicker at the rear.

Furthermore, it also has a longitudinal groove for improved air circulation during exercising. However, it’s a standard seat, and in case you want a different one, compatible options are widely available.

The handlebar is also 4-way adjustable, just as the seat. Its upright bar offers seven adjustment positions. It features a multi-grip design, with a loop aero bar in the middle, which is pretty long, providing plenty of space to rest your elbows during a cycling trip.

The handlebar has a layer of rubber foam material that provides a secure and comfortable grip.

ESB250 Resistance system

Like most bikes, the Endurance ESB250 features a manual, top-to-down friction resistance system. This means you don’t have to connect the bike to a power source.

The main elements of the resistance system are a large rubber/leather pad attached to the central tube of the frame and the tension dial on top of this tube. Therefore, as you turn the dial, the pad applies more or less friction to the flywheel, increasing or decreasing the resistance.

Since it’s a standard friction resistance system, it doesn’t have distinct tension levels. You can turn the knob until the brake pad delivers the tension that you feel’s comfortable. As a general idea, you can tighten the pad up to the point you can barely pedal.

The bike’s tension knob also fulfills the role of an emergency brake. You can press it down to immediately stop the flywheel from spinning. This feature is necessary, as the pedals continue to turn for as long as the wheel is spinning.

It’s also important to mention that the bike’s brake pad may generate a squeaking noise when in contact with the flywheel. A little silicone lubricant applied on the edge of the wheel will take care of the sound.

The pad will also wear out after a while, and it will require replacement. However, since it’s a standard pad, replacement options are widely available.

Drive System

The first aspect that we’re going to focus on here is the flywheel. The Endurance ESB250 comes with an extra-heavy, 44 lbs (20 kg) flywheel, which is perimeter-weighted, to deliver highly aggressive inertia. This gives a very consistent momentum, but the pedaling motion is very stable and smooth.

The bike is equipped with a belt drive system, using a heavy-duty, poly-v belt, which provides superior traction. Just like any belt-drive, it offers three main advantages. One, it generates less vibration than a chain; two, it doesn’t require lubrication; three, the pedaling motion is whisper-quiet.

Another essential element of the bike’s drive system that we must cover here is the crankset. As we’ve mentioned above, the bike can support users up to 350 lbs (159 kg), and this also stands for its crank and pedals. So, even if you weigh this much, you should be able to pedal while standing up on the pedals without a problem.

The pedals included with the bike are dual-sided, with toe cages and straps for regular athletic shoes on one side, and pro-style clipless elements for spin shoes on the other. They also feature standard threads (9/16), so you can easily find replacements for them if needed.

One last aspect to mention here regards the bike’s Q-Factor (spacing between the pedals). Although this dimension is not specified in the manual or on the official website, it is evident that this indoor cycling trainer features a very narrow Q-Factor.

Specifically, this means your feet are positioned on the pedals naturally, without being too far apart, and this way, there is no additional lateral stress on the knees and ankles.

ESB250 Assembly and Maintenance

The Endurance ESB250 exercise bike comes partially assembled. The flywheel, the brake, the belt, and the crankset are already constructed, attached to the frame. Therefore, you only have to connect the bike’s bases, the seat, and the handlebars. The manual provides step-by-step assembly instructions, and an essential toolkit is also (included).

Since the bike has a belt-drive, it doesn’t require lubrication. The brake pad may need a bit of silicone lubricant in case it generates a squeaking sound when in contact with the flywheel. Other than this, it is recommended to inspect the bike for loose parts and bolts periodically.
