How long will the Proform 505 SPX last?

The Proform 505 SPX Indoor Cycle has a compact design and weighs approximately 110 lbs. when fully assembled. It is a miraculous mix of steel and plastic that can hold users up to a 250 lb. weight limit and is built to last for more than a minute. Moderate use will enable a couple of years of riding fun from this machine. The HSN website offers the 505 SPX with a 5-year limited warranty on the frame and 90 days on parts and labor. Keep in mind that even the simple addition of a mat beneath the cycle will add to the lasting quality of the machine.

Brief Overview

The Proform 505 SPX Indoor Cycle was the 2nd place winner for the 2021 Best Buy in the $399 and under price point and it offers quite a few quality features even though any exercise machine in this price range is a gamble. It is cost competitive, heavier than other models priced the same, and does offer an entrance to the world with a download of the iFit app and continued paid subscription.

Overall Quality

The 505 SPX Indoor Cycle has a 40 lb. flywheel that lets users enjoy smooth performance and accelerating during all facets of exercise while resistance levels are changed with the simple twist of a knob. It also contains a belt drive system that is hardier than the chain drive systems which tend to break faster. The 505 SPX has a small LCD display screen that shares pertinent information during workout sessions but the addition of an iFit membership opens the door to elite trainer workouts and jaunts to far off spots during cycling exercise with the quick download of the iFit app. Other amenities on the 505 SPX are the step through feature that allows users to easily climb on or off, attached wheels for transport if needed, and a convenient water bottle holder to support hydration efforts.

The 505 SPX Indoor Cycle is quite cost competitive and is a decent exercise machine that will fit right into any home gym setting. It is built by a reputable company and despite the lack of warranty, is a stellar operating machine. While the display screen leaves a lot to be desired, the ability to stream iFit through users own devices is still more tech than most models in the same price range and even higher.
