However, before providing all the details and information regarding this exercise bike, one thing must be clarified. There are actually several Marcy Club Revolution bikes. For example, a different one is the Marcy Club Revolution XJ-3220. The model number presented here is the JX-7038, which comes with slight differences from the others.

Drive system

To begin with, the JX-7038 exercise bike from Marcy Fitness is equipped with a belt drive system. It features a heavy-duty belt, highly resistant to stretching. Since it’s belt-driven, the bike supplies a very smooth and quiet cycling motion, making this bike model ideal for home use.

The flywheel of this bike is pretty heavy, weighing 40 lbs (18 kg), and providing a consistent momentum. It’s also perimeter weighted, which renders the pedaling marcy jx-7038 flywheel and brakeconstant and stable, diminishing the stairmaster effect, which may be quite pronounced in case of a simple flywheel, especially under a high resistance setting.

The crank assembly features a rather small pulley, a bit over half the diameter of the flywheel. Both the pulley and crank arms are steel-made, solid enough to support users up to 300 lbs, in a stand-up workout posture.

The pedals of this bike are aluminum-made, and finished with toe-cages. Even though this is a stationary bike, and there’s less of a chance for your feet to slip off pedals, the toe-cages are still great for users who undergo recovery training, and do not have complete control over their feet. These pedals do not have cleats, but they have a standard design, so you can easily find replacement if you really desire cleat pedals for spin shoes.

Resistance system

This Marcy exercise bike is equipped with a direct-contact brake system. It consists into a single, long wool-felt pad, which comes in contact with the flywheel in a top-to-bottom manner. Resistance adjusting is done manually, via the tension knob found on the main tube of the frame. There are no resistance levels specified on the knob, so basically you must tighten it up to the point when you find the tension suitable for your workout. Tension can be adjusted while pedaling. The tension knob also acts as an emergency brake, in case you need to quickly stop the motion of the flywheel, or if you want to safely switch from normal pedaling, to backwards pedaling.


This exercise bike features a one-piece frame, with extremely solid welding points. The frame of the bike is completely made of steel, quite heavy, which gives the bike plenty of stability. Speaking of stability, this particular aspect is enhanced by the level adjustment knobs the bases are equipped with. Both front and rear bases are finished with adjustable leveler knobs, to make sure the bike will not move anyhow during your workouts.

The front base features two transport wheels, plastic-made, which allow the moving of the assembled machine with ease.

So far, this model is only available in black, grey and yellow colors, with the pattern visible in the attached photos here.

Seat and handlebars

The Marcy JX-7038 features a slightly cushioned seat, similar to the ones in race bikes. It’s not extremely comfortable, such as the seats in recumbent or upright bikes, but it does offer just about the same comfort that a race or mountain bike should offer. It’s adjustable vertically and fore to aft. Vertically, it offers 10 height increments from 35″ (89 cm) to 44″ (111.7 cm) from the floor. Since the pedals in their lowest position stand about 3″ from the floor, this leaves a roughly 32″ (81 cm) distance from the lowest pedal to the seat, in its lowest position. Therefore, we can safely say that this bike can accommodate users with a minimum inseam of about 30″. Differently put, this bike should fit users between 4’10” (147 cm) and 6’5″ (196 cm) without any problem.

The handlebars are also height-adjustable. There are 6 adjustment increments on the handlebar post, from 36″ (91.4 cm) to 41″ (104 cm). The handlebar assembly does not offer fore to aft. adjustment possibilities. However, it does offer multiple grip possibilities, which considerably enhances the workout posture spectrum. On top of that, it features aerobars and elbow rests, just as race bikes. The whole handlebar assembly is covered with foam padding for an ergonomic grip and to prevent hands from sustaining blisters, during prolonged workout sessions.

Assembly and Maintenance

The assembly of this indoor cycling bike is far from being a complicated process. The box includes a very comprehensive, step-by-step assembly manual, and the tools required for it. The bike actually comes partially put together, with the drive and brake systems already mounted in their place. All you have to do is attach the frame to the bases, add the seat and handlebar posts, then the seat and the handlebar assembly, the pedals and the elbow rests.

Since it’s a belt-driven bike, you won’t have to worry about any maintenance related to the drive system. All the parts are prelubricated and this should last for a long time. In terms of maintenance, all you have to do is lubricate the felt-pad from time to time, and replace it when it completely wears off, check if all the bolts are well tighten in their places, and keep the bike clean. Also, since the base levelers are metallic, it’s best to use a mat underneath the bike, as it might damage your floor.

Best Aspects About This Bike

  • Extremely sturdy and durable bike.
  • Quiet, excellent choice for apartment use.

  • No performance monitor.
  • Finally, the seat may be a bit uncomfortable to new users. However, the discomfort should diminish after several workout sessions. If not, you can always add a gel marcy club revolution jx-7038cushion to the seat.

Final Word

The Marcy JX-7038 indoor cycling bike is one of the most affordable bikes for spin training that you can find at the moment.
