Resistance Levels

Eddy current is mainly a motorized-magnetic system. The Nautilus U616 uses this resistance system, which means that you always have kept it connected to the power source to get resistance adjustments.

You can change the resistance adjustments accessing the console or set them to adjust the resistance automatically. Within the package of the bike, an AC adapter is included. The input credentials are 120V 60Hz and the output is 9V DC, 1.5 A current.

Nautilus resistance

You will find the connector at the front base. There are no options to use this console with batteries. 25 different resistance levels are available on this bike. During the first 5, you'll feel very low resistance.

The light levels are great for recovery and the elderly. But you will feel consistent pedal tension throughout the whole resistance level.

Weight balance is another vital thing to look into an upright bike. The flywheel used in this bike weighs about 22 lbs. This perimeter-weighted structure provides better inertia during workouts, which makes the experience very realistic.

Speaker for Entertainment

Using the media cable, you can connect your device to the console. The speakers are not very loud but they can be an alternative to headphones. Volume control options are not available in the console; you can control them by your device.

Adjustable Padded Seat for Comfort

One thing is sure of praising that the seat used in the U616 is very comforting. A thick layer of foam cushioning is attached to the saddle, which provides extra flex and movability. If you want, you can always add an extra seat cover as per your likes.
