Best Diamondback Treadmills of 2024

FitRated Editorial Team | Jun 15 2022 - 8:51 am

Diamondback Fitness builds and sells affordable treadmills for home use. They have two models: the 510T Treadmill for walking, and the 910T Treadmill for walking and running. Each model is sale priced under $1,000 including delivery and a competitive warranty… and you won’t need to pay for assembly, as explained in our buying guide below.

Each Diamondback treadmill stands out from competitors in different ways.

The 510T is especially compact: Its track is short and narrow to save floor space, and the machine folds flat for under-the-bed storage.
The 910T is remarkably spacious: Its track is longer and wider than the standard. This treadmill model can be folded too, but it gets stored upright.

Both Diamondback treadmills have preset workout programs, and both have speakers to support multimedia entertainment. You can compare the 510T and 910T with the following treadmill comparison chart.

Diamondback Treadmills Buying Guide

This treadmill buying guide describes the Diamondback 510T and 910T, and it provides an overview of Diamondback Fitness.

Diamondback Treadmill Choices

Two treadmills are in the Diamondback lineup this year: the 510T and 910T. Both have competitive home-use warranties.

Smallest Treadmill by Diamondback

Diamondback’s new 510T Treadmill is a top choice for shoppers who’d like to stroll miles indoors but have little room for home fitness equipment. This foldable treadmill is unusual for being small enough to store beneath a bed, yet durable enough to carry a three-year warranty on parts and electronics.

Full price is just $799, making the new Diamondback 510T one of the cheapest treadmills on our review site. Additionally members of the US military get a 10 percent discount on Diamondback fitness equipment anytime.

Just how small is the 510T? Its folded dimensions are 66” long x 30” wide x 11” high. The workout area measures 17 inches wide and four feet long. Therefore this machine wouldn’t be comfortable for very long-legged users to use, but it gives the average person enough room to stride normally. For comparison most treadmills at health clubs have workout spaces that measure three inches wider and a whole foot longer.

Other specs for the new Diamondback 510T include: a 2.0 HP motor with lifetime warranty; 10 preset workout programs; a contact heart rate monitor; and a stereo speaker set for your tablet, phone or MP3 player. Its maximum speed is 8 mph.

All in all this treadmill has impressive features for the price. If you have floor space to spare though, we recommend considering the bigger 910T. It provides 4.0 CHP, power incline for the track and other upgrades.

Best Treadmill by Diamondback

Spacious yet foldable, the Diamondback 910T Treadmill is a top value for home workouts of any intensity. At $899 it doesn’t cost much more than the ultra-compact 510T, but it provides lots more workout room and 4.0 continuous horsepower.

The 910T Treadmill belt is both wider and longer than the norm for club treadmills; it measures 21.5” x 63”. These dimensions help make the treadmill comfortable for a trainee of any height, whether they’re walking or taking long running strides. The belt’s max speed is 11 mph, and its 4.0 CHP motor exceeds the standard for the price class.

Other specs for this unit include: 15 levels of incline; deck cushioning to reduce impact by about 25 percent; 15 preset workout programs; a contact heart rate monitor; and a stereo speaker set for your mobile device. Altogether the features are very impressive for the price.

The new 910T normally costs $899 including delivery, and the machine arrives about 80 percent assembled. Members of the US military get a 10 percent discount.
