Sunny Health & Fitness T7643 Features and Specifications

When unit arrives, it must be assembled - it can be done rather quickly since the bottom frame with the walking/running deck and belt, and electric motor comes fully assembled.

Just to be sure, prior assembly and the first use, be sure to thoroughly read the manual/instructions.

In order to save on storage space, unit can be folded - walking deck can be lifted upwards. Unit comes with the soft drop hydraulic mechanism which assures safe, almost hands free folding and unfolding.

Also, unit comes with the transport wheels to help with moving the unit around. Nonetheless, it is recommended to place the unit on permanent location and use whenever one has time.

Sunny Health & Fitness T7643 treadmill comes with 43.3 inches long and 19.5 inches wide (~110 x 49.5 cm) walking/running deck.

Note: here we use 'walking' and 'running' often interchangeably since Sunny Health & Fitness T7643 treadmill speed ranged between 0.5 and 6.0 mph (0.8 - 9.7 km/h) and can be used not only for walking, but also for light jogging.

Running treadmills have larger running deck, but 43.3 x 19.5 inches deck is more than large enough for comfortable walking.

Also, to protect joints, especially the ankles, knees and hips, unit comes with shock absorbers built into the walking deck - very important since large and heavy people already have joints under large load and stress.

Unit comes with 2.5 Peak HP motor, which is more than strong enough for walking treadmill. For example, good running treadmill with 350 lbs maximum user weight must have at least 3.5 CHP motor in order to provide smooth and reliable operation.

Sunny Health & Fitness T7643 Controls and Display

Sunny Health & Fitness T7643 comes with simple, yet very effective controls.

When the unit starts, if magnetic safety key is at its position, unit will start 3 second countdown and start with default 0.5 mph speed.

To adjust the speed, the user can use Quick Speed buttons and set 1 mph, 3 mph or 5 mph speed, or +/- buttons can be used to adjust the speed in 0.1 mph intervals.

When pressed once, Stop button pauses the running belt and current workout data, while pressing the Stop button again terminates the workout session.

 Unit uses backlit LCD monitor to display current workout data. Although at first LCD monitor looks small, it shows all data simultaneously and is easy to read:

- Speed: displays current speed or setting mode (more on that later),

- Time: depending on the selected mode, it displays exercise time from 00:00 to 99:59. When workout reaches 99:59, belt stops smoothly, 'End' is displayed and unit goes into a standby after 5 seconds. If countdown mode is chosen, time counts toward 00:00 and when it is reached, belt again stops smoothly and 'End' is displayed.

- Distance: displays the distance traveled during exercise and ranges from 0.0 to 99.9 miles. When in countdown mode, it counts from set distance to 0.00. Again, when the unit reaches desired goal (distance!), belt stops smoothly, 'End' is displayed and after 5 seconds, unit goes to standby mode.

- Calories: displays the calories burned during walking (from 0 to 999 kcal). Also, when in countdown mode, it starts from set value down to zero and when it reaches 0, unit stops slowly, displays 'End' and after 5 seconds the treadmill goes to standby mode.

Calorie counter is not the most accurate one since it doesn't take into account age of the user, weight, heart rate and other important details for counting calories. However, calorie counter is good for comparing current exercise with previous ones.

Console doesn't feature cooling fans, multimedia center or anything similar. But, it has two water bottle holders and wide tablet/smart phone (not included, of course) holder - one can stay well hydrated during long power walks and can listen to favorite music or watch content on the tablet, smart phone or even TV in to room, since the unit is relatively quiet.

Sunny Health & Fitness T7643 comes with 3-Year structural frame warranty and 90 days warranty on other parts and components. IMHO - Frame warranty is good, but this 90 days 'other parts and components' warranty could be better.


sunny t7643 walking treadmill 2Long Story Short: Sunny Health & Fitness T7643 lacks few features that are almost commonly found at treadmills in this price range, like heart rate monitor, preset programs, automatic or at least manual incline, cooling fans, online connectivity, multiple users, sound system and similar.
