Nautilus T618 Construction

Nautilus treadmills hold the reputation of being very robust and longlasting.

Steel support beams keep the Nautilus Fitness T618 foldable treadmill’s structure robust and the surface upright.

The Nautilus Treadmill T618 is a huge treadmill with the dimensions of 72.4″L x 35.2″W x 57.6″H.

The Nautilus T618 Treadmill is spacious and durable with a steel frame, high capacity motor, large rollers, 3-ply belt, automatic incline, excellent deck cushioning, excellent impact absorption, easy-to-read console, four user profiles, etc. The Nautilus T618 has a basic LCD panel and Bluetooth also.

An ample exercise space, improved cushioning, and a 3.5 HP motor help make it a terrific bargain for runners. You’ll also receive Pacer, Compare, and Fitness readings to motivate you.

Motor

The 3.5 HP motor is quiet and powerful enough for most runners allowing for speed adjustments from 0.5 to 12 mph. 

That’s fantastic for walking and jogging. For most people, the 3.5 HP motor should be enough. You may stroll, jog, or work up to a 15% incline. So you may increase the intensity while keeping the impact mild.

The motor is beneath the deck, like with previous folding treadmills. The T618’s motor hood is lower than others we’ve seen, so your foot won’t graze it when running.

Like any treadmill, there is some noise from foot contact during running, which is louder than walking though overall, this is a quiet machine. The machine is significantly louder when inclined, perhaps because the deck pivots up, preventing noise from being trapped beneath.

Speed & Incline

The running deck inclination is motorized and may be altered from 0 to 15% automatically or manually.

We can have various combinations by fine-tuning or adjusting fast set speed and incline buttons from 2 to 12 mph in 2 mph increments and inclination from 0 to 15%

Console & Display

Two 3.75′′ and 5.5′′ blue backlit LCDs show workout progress.

The 3.75″ top monitor shows the exercise objective, user fitness score, and pacer positioning.

The 5.5″ bottom displays program profiles, running time, distance run/lap, heart rate, calories burnt, running speed, incline %, and pace.

The T618 can function with full-color fitness programs linked to a tablet or smartphone.

A small panel with big green and red Start and Stop buttons sit below the central console. The fan blows at around chest height. Simple up/down buttons for speed (right) and inclination (left) changes. The safety key is on the lower panel.

Under the console is an accessory tray for a towel and a water bottle. Two storage cups are on either side of the Nautilus T618 console to enhance storage capacity.

The lack of a touchscreen means the display is digital, but it doesn’t affect your ability to utilize and navigate the controls.

The treadmill’s media shelf can securely accommodate your tablet computer for entertainment, training advice, or multitasking.

Each exercise ends with a fitness score to help you track your improvement.

Handrails have contact pulse monitors, and the Nautilus T618 accepts a wireless chest strap (included in the purchase).

Distance may be shown in miles or kilometers and speed in mph or km/h.

The Lap Count feature shows the distance in 0.25 mile (0.4 km) laps, useful for people training for “track and field” competitions.

A tablet shelf sits atop the console, immediately in front of the Bluetooth display. The top of the console has a USB connector for charging your mobile while playing. You may use this to access workout applications, Netflix, or read a book. All app services need a subscription and are not included in the Nautilus T618 purchase.

Easy to Fold

The treadmill frame folds down for simple storage between sessions.

The Nautilus T618 treadmill is foldable. You may fold up the treadmill’s deck after use to save space.

Because the motor is at the front of the deck, You may fold it vertically. The treadmill folds flat on rollers beneath the frame. The deck locks vertically to prevent unintentional opening.

A folding mechanism enables the T618 deck to rotate up and lock against the console. This way, you can open the deck as required and close it when you’re done. The locking mechanism is secure, so youngsters or dogs can’t unlatch it. A soft-drop mechanism modulates the deck’s descent to avoid a thud.

Running Track

The T618’s running surface is 20″ broad, and you get 60″ length, which is ideal for those with long strides or 6 feet or above. The running deck is 9″ above the floor, with a maximum gradient of 15%.

In contrast to the traditional home treadmill, the T618’s 3-ply, 2.5 mm thick running belt revolves around 2.75′′ rollers. Larger rollers reduce friction and stress on the belt, which increases belt life and comfort. The 3-ply belt surface is lightly textured for a good foothold.

Two pair shock absorbers cushion the running deck up front and three pairs at the back. In addition to cushioning shocks, Nautilus’ Rebound Cushioning allows the T618 to flex slightly underfoot. It reduces joint fatigue. Users may exercise longer and harder without injuring their joints or spine.

Preset Programs

There are 26 workout programs to choose from, focusing on cardiovascular endurance, weight reduction, or interval training. Use Bluetooth to connect the treadmill to your smartphone or tablet to enjoy RunSocial workouts with streaming visuals.

The console also has 26 training routines organized into categories:

  • Quick Objective: enables users to specify an activity goal like distance, time, or calories.
  • Heart Health: preset goal heart rates of 55%, 65%, 75%, and 85%.
  • Exercise presets include Fat Burn 1, 2, 3, Speed, Incline, and Dual.

  • Customizable heart rate, inclination, and speed programs

The Nautilus T618 treadmill stores four user profiles: age, gender, weight, height, desired exercise parameters, and name.

Each profile allows you to record your exercise outcomes. Also, the calorie counter is more accurate due to user data kept.

With Bowflex’s Explore the Globe app, runners may see diverse landscape courses recorded worldwide. It can also link external fitness applications through Bluetooth for extra training information. T618 keeps track of stats while watching the app on your phone or tablet. A tablet is not provided, and you must pay for any third-party applications.

The T618 has no subscription options. Preprogrammed routines give you all the training you need. As stated above, the treadmill may sync with third-party applications.

SAFETY

The belt and deck should be maintained clean, and the belt should be oiled after 25 hours of usage. Check for loose pieces (bolts, cables, etc.) and similar objects.
