Frame construction

The Spinner P1 is definitely an exercise bike designed for spin workouts. It features a highly durable frame with a commercial construction and an impressive weight capacity of 350 lbs (159 kg). The main chassis of the bike is made of thick steel tubing with precision-welded connection points. However, the seat and handlebar posts are aluminum-made. Also, the bike’s construction contains a few ABS parts, the most notable being the chain cover.

The main frame is coated with compact paint finish, “Warm Silver” in color. This paint finish is sweat-proof, highly resistant to corrosion and abrasion. Of course, the aluminum posts and sliders have their own natural polish.

The frame section above the crank is durable enough to be used as a stepping element. Although it doesn’t have a pad on top, and it’s slightly oblique, it can definitely serve as support for the spin workouts that require you to step-on and step-off the frame.

The fully assembled bike is fairly heavy. It weighs approx. 108 lbs (~49 kg). This is more than twice the weight of the average mountain bike. Therefore, the bike definitely offers an outstanding stability without rocking or wobbling even if you engage in the most demanding spin workouts.

The unit’s stability is also enhanced by the large, rubberized and adjustable stabilizers. Plus, once it is fully assembled, the bike is quite easy to relocate and handle because its front base integrates a set of large silicone wheels.

One last aspect to mention here regards the bike’s dimensions. This spin bike is approx. 49″ (124 cm) long, and 20.5″ (52 cm) wide. This being said, it doesn’t take too much space compared to other items of fitness equipment. However, it is recommended to assign an area of at least 70″L x 50″W (178 x 127 cm) for it, for easy access and unhindered operation.

Seat & handlebars

The Spinner P1 indoor cycling bike is equipped with a slim and rounded spin seat. Now, this type of saddle may not be too comfortable for users new to spinning. It’s not a bike seat made for comfort; plus, since it’s a spin bike, you should be pedaling while standing up for at least a part of your workout.

But nonetheless, the bike’s saddle has a standard attachment system. This being said, replacement options for it are widely available. Also, you can add comfort to it via a gel seat cover.

The seat is 4-way adjustable (up, down, forward, backward). Its upright post offers multiple adjustment positions, while its front-back adjustment slider can also travel for a few inches. This being said, the bike is designed to accommodate users up to 6’6″ (198 cm), promoting a complete and satisfying leg extension.

Since this is the most basic trainer of the Spinning Performance series, its handlebar only offers upright adjustability. This being said, the handlebar offers several inches of up-down adjustment.

The handlebar features a wedge design keeping the bars secure and solid. It has an integrated, loop aero bar and offers a multi-grip design. It’s fully covered by a layer of urethane (or other similar material) in order to supply a comfortable and secure grip.

Resistance system

Just like the Spinner L3 of the LifeStyle series, the P1 features a friction resistance system. The main resistance element is the leather pad attached to the frame at the top of the flywheel, and to the tension knob on top of the main tube of the frame.

This resistance system is completely manual. By turning the knob clockwise, the brake pad applies more friction to the flywheel which results in a higher pedaling difficulty. There are no tension levels marked on the knob. You can basically tighten the pad on the flywheel up to the point you can no longer pedal.

The bike’s tension knob doubles as an emergency brake. You can press it down in order to immediately stop the flywheel from spinning. This may be required in certain cases, especially if pedaling at a high speed, as the pedals will continue to spin for as long as the flywheel is spinning.

Drive system

With regards to the bike’s drive system, there are several elements that we must cover here. The first one is the flywheel. The Spinner P1 is equipped with a heavy, 40 lbs (18 kg) flywheel which has a perimeter-weighted structure. Differently put, it’s a high-inertia flywheel designed for spinning workouts. It supplies a steady motion and a great ride experience.

Since it’s a spin bike, the Spinner P1 is equipped with a highly durable crankset. Its solid steel crank arms and metallic pedals can support users up to 350 lbs (159 kg) in full standing up position, and for any spin workout.

The pedals are dual-sided. They’re equipped with adjustable toe cages on one side, and SPD elements on the other. They also have standard 9/16″ threads, so you can easily find replacements for them if it’s the case.

Last but not least, the bike’s transmission uses a chain. It’s basically a standard bike chain which can last a lifetime with proper care. You can also easily find a replacement for it, if needed, in any bike shop.


This spin bike doesn’t include a fitness meter but does come with several notable accessories. The first to put on the list is the dual bottle holder integrated into the handlebar. This is a “gravity-based” bottle holder; each bottle slot is large enough to accommodate any type of hydration bottle.

The bike includes a set of four DVDs with spin workouts. In case you’ve never been to a spin class before, the workouts on them are quite educational, motivational and entertaining. They’re quite great to train with. They actually generate the atmosphere of a real spin class, and will considerably help with your results. The DVDs include Ultimate Energy, Train and Tone, Turn and Burn, and Maximum Results workouts.

Last but not least, the Spinner P1 comes with a free, 1-year subscription to SPINtv which is an online library of instructor-led spin workouts which you can stream any time you want on your tablet or smartphone.

Assembly & Maintenance

The core of the bike comes pre-assembled. In other words, the flywheel, the chain drive, the brake system, and the crankset are already attached to the main frame. All you have to do for assembly is attach the base stabilizers, the seat, the handlebars, and the pedals. This task shouldn’t take more than 20 minutes; the included manual provides all the necessary instructions, and some of the tools required for it are also included.

For maintenance, it’s recommended to periodically lubricate the chain. The manual provides instructions for it. Other than this, it’s recommended to check for loose or broken parts from time to time, in order to replace or re-tighten them.
