What We Like

Weight Limit: One of the biggest highlights of this Sunny T7643 treadmill is that it can load up to 350 pounds of user weight, which is rare to see in budget models.

Price: Sunny allows you to get fit without spending much by providing affordable walking treadmills.

Deck Width: This treadmill gives you a wider deck, so you can comfortably swing your arms at your sides without hitting them on the machine.

Motor: The T7643 treadmill gives you a 2.5 HP motor, the standard number you may find in its price category. 

Shock Absorption: Sunny integrates shock absorption technology on the deck that minimizes impact and maximizes your joints’ health in the long term.

Folding Design: As it is a foldable treadmill, it is very convenient, especially for small spaces.

Soft-Drop System: This walking treadmill has a built-in soft drop technology that assists you in slowly folding or unfolding the deck.

What We Don’t Like

No Programs: The Sunny T7643 doesn’t offer preset programs. You have to hold your device on the console to watch videos.

Deck Length: Although it provides a wider deck, its length is short. However, it may be fine for regular walking.

No Incline: This treadmill doesn’t offer incline adjustments. You may find incline in some of its competitors.

No Pulse Sensors: No heart rate pulse sensors are available in the T7643 treadmill.

Here’re the key highlights of these treadmills:

The Sunny T7643 and Exerpeutic TF1000 are pretty similar in terms of features. However, you get a slightly higher weight limit in Exerpeutic, but the stronger motor is in the Sunny.

Both the treadmills are very basic with no entertainment option.

Remember, you should choose a treadmill with a 30-50 pounds higher weight limit than your body weight that helps you increase your machine’s durability and get a stable training experience.

If you want a treadmill with programs and workout videos, you can look for NordicTrack T 6.5 Si, which includes a 30-day iFit membership, auto incline, and several other features that can make your walking and jogging session more exciting and fun.

However, you need to pay for iFit membership after the free trial ends.

The Sunny T7643 Treadmill Could be for You, if:

  • you’re looking for a basic treadmill for regular walks.
  • you’re looking for one of the best higher-weight capacity treadmills (like 350 lb) at an affordable price.
  • you want to go with one of the most trusted brands in the treadmill industry. 

Final Word

The Sunny T7643 is a basic treadmill packed with a good combination of features that can fulfil your everyday walking needs very well.

Joggers and runners should look for more powerful treadmills.
