Talk to a treadmill specialist| Motor | 3.5 HP |
| Speed Range | 0.8 - 18 km/h |
| Running Surface | 125 cm x 45 cm |
| Incline | 15 levels, automatic |
| Max User Weight | 120 kg |
If you walk daily and jog a few times a week, the CHI 450 runs a 3.5 HP motor across a 0.8 to 18 km/h speed range with 15 automatic incline levels. It carries users up to 120 kg and folds away with a hydraulic fold-down system so the floor clears between sessions.
The trade-off to know up front: the 125 cm x 45 cm belt is sized for walking and jogging to about 12 km/h (users up to about 185 cm), not running, so the 18 km/h top speed is headroom. For walking, jogging and incline work, the 5-inch LCD runs 12 training programs and tracks speed, time, distance, calories and pulse without a phone.
What catches my eye here is the 15-level automatic incline paired with that butterfly spring joint system and 6-point rubber cushioning: for a folding treadmill, that's a genuinely forgiving ride underfoot.
The belt sets the limits: 125 cm long suits walking and jogging to about 12 km/h, not running, and the 120 kg user cap rules out heavier users. The hydraulic fold and transport wheels are its real win for tight spaces.

The 3.5 HP motor gives you a wide speed band, from a gentle 0.8 km/h walk right up to 18 km/h, with the 125 cm belt sized for walking and jogging.
With 18 speed levels you can nudge the pace in small steps rather than jumping between gears.
What this means for you: The motor has speed in reserve; the 125 cm belt is sized for walking and jogging to about 12 km/h, so it sets the ceiling rather than the motor.
Fifteen motorised incline levels let you add gradient at the press of a button, which raises the effort without touching your speed.
Because it is automatic, your training programs can shift the incline for you mid-session.
What this means for you: Adding incline is the simplest way to lift intensity when walking starts to feel easy.
The deck uses a butterfly spring joint support system paired with six rubber cushioning points to take some of the harshness out of each footstrike.
The running board is a high strength composite board with an anti-slip, wear-resistant belt on top.
What this means for you: A deck with give feels kinder underfoot on longer walks than a bare, rigid board.
The 5-inch LCD screen keeps your key numbers in view and runs 12 built-in training programs, so you can follow a set routine instead of guessing.
Pulse sensors in the handles give a rough heart-rate read while you hold on.
What this means for you: The grip sensors handle casual use; add a chest strap for accurate heart-rate zones if you train to intensity.
The hydraulic fold-down lets you lift the deck up and out of the way, shrinking the footprint from 160 cm long to 104 cm folded.
Transport wheels mean you can roll it to a wall or into a cupboard between sessions.
What this means for you: Hydraulic-assist isn't automatic; you still guide the descent, but it takes the strain out of lowering the deck.
The running surface measures 125 cm long by 45 cm wide, a standard home width that suits walking and steady jogging.
The frame supports users up to 120 kg.
What this means for you: 125 cm covers walking at any pace and jogging to about 12 km/h for users up to about 185 cm; it isn't sized for running at 12 km/h and faster.
The powder-coated steel frame gives the treadmill its stability and takes the knocks of daily use.
It's covered by a 12-month warranty.
What this means for you: If this page shows the 100 Day Money Back Guarantee badge, you have 100 days to decide at home.
Small touches make daily use easier: dual drink holders keep water within reach and dual built-in speakers play audio through the USB or MP3 input.
Soft-grip handles give you something steady to hold during walks or warm-ups.
What this means for you: These are the details you notice on day 50, not day one, and they keep sessions hassle-free.

At a walking pace the 3.5 HP motor stays quiet enough to use during a phone call. As you pick up to a jog you'll hear more of the motor and your footstrike. Your weight and shoe choice add to it, so a 6 mm rubber mat under the deck helps reduce noise transfer to rooms below.
The 125 cm x 45 cm belt covers walking at any pace and jogging to about 12 km/h for users up to about 185 cm. The 45 cm width is a standard home width, fine for walking and jogging. If you plan to run at 12 km/h or faster, look for a belt of 130 cm or longer, and longer again if you're tall.
Set up, it measures 160 cm long, 70 cm wide and 127 cm high, so it fits comfortably under a standard ceiling. The hydraulic fold-down brings the footprint down to 104 cm long once folded, and the height rises to 155 cm. Transport wheels let you roll it against a wall between sessions. Hydraulic-assist still means you guide the descent, so it stays controlled.
The CHI 450 supports users up to 120 kg. It suits walkers, joggers and anyone building a cardio habit at home who wants automatic incline and preset programs without a huge footprint. If you run daily at high speed or sit above the weight limit, a larger-frame treadmill will serve you better long term.
The grip pulse sensors give you a rough heart-rate reading, fine for keeping an eye on effort during steady sessions. They're not precise enough for strict heart-rate zone training. If you want accurate zones, use a separate heart-rate monitor and the console for everything else.
