Seat and handlebars

The seat supplied with the Marcy NS-40504U exercise bike is a simple, standard bike saddle, with a thin layer of padding. It’s definitely wider than most seats specific to spin bikes, marcy ns-40504u - seatthereby the bike offers more comfort than a spin bike.

The seat is only 2-way adjustable, up and down. Its post offers several adjustment positions, being able to accommodate users between 4’10” and 6’2″ (147 – 188 cm), or differently put, users with an inseam up to 35″ (89 cm). Also, the seat and the overall frame construction can support users up to 300 lbs (136 kg), which is not bad for a basic upright bike. Other models, such as the Best Fitness BFUB1 or FitLeader UF4 have a weight capacity under 250 lbs (113 kg).

The bike’s handlebars don’t offer any adjustment possibilities. They connect to the upright console mast of the bike via two bolts. They feature a multi-grip design though, promoting several workout postures. They also have rubber foam grips, to provide optimal comfort. This exercise bike cannot monitor heart rate, thus the handlebars do not have pulse sensors.

Resistance and drive

The Marcy NS-40504U features a manual magnetic resistance system, which involves a magnetic resistance pad, and a metallic flywheel. The magnetic pad is connected to the tension knob on the bike’s console mast, via a steel wire.

The console unit is easy to use. It automatically turns on when you begin pedaling, and will self shut-down after 4 minutes of inactivity on the pedals. It has three function buttons: SET, RESET and MODE. The SET button is used to setup a target value for time, distance or calories. MODE toggles on and off the SCAN function, while the RESET button clears all the values to zero.

The console uses 2 AA batteries which are not included.

One more aspect to mention here regards the console’s tablet holder. This consists of a narrow tray, placed under the console keys. It’s wide enough to support any tablet, smartphone or magazine. However, the console does not have an audio jack, nor a USB port to dock your device.
