The Bigzzia treadmill is one of the best-selling truly flat treadmills on the market, and after 12 weeks of testing it's easy to see the appeal. It's a stripped-back, barebones machine built around three things buyers actually want: affordability, speed and portability. The question is whether it delivers, or whether there's a better option out there. Here's where it earns its place and where it cuts corners.

The Bigzzia running machine is equipped with a handful of genuinely useful features. The headline, and probably why you're reading this, is its size and portability. It's lightweight, easy to move thanks to built-in transport wheels, and flat enough to store underneath furniture.
Speeds range from 1 to 10km/h, all adjusted via the supplied remote control. On top of that you get a quiet motor, a running belt with decent shock absorption, and a durable steel frame. But are they any good? After 12 weeks of testing, here are the best and worst features of this machine.

The biggest selling point of the Bigzzia is its size and portability. This is a treadmill built for people who don't have much floor space, or who simply want to tuck the machine out of sight when it's not in use.
I'm one of those people, which is exactly why I bought and tested this machine over 12 weeks, to see whether it really works as a treadmill you can store away without any hassle.
It measures 120cm x 50cm x 14cm, making it one of the slimmest treadmills you can buy. That's slim enough to slide underneath or behind most sofas, and at 23.5kg it's light enough to make doing so painless. My biggest concern was whether dragging it out from under the sofa every day would become a chore. I can say with some certainty that, while it's not feather-light, it's easy enough that it never feels like it's getting in the way of a run.
With the rise in home working, the desk treadmill has quickly become a staple of the home office. For office exercise equipment, the Bigzzia gets the fundamentals right.

Being a slim, portable walking machine, the Bigzzia can be placed in front of or underneath your desk so you can get your steps in while working. Thanks to its noise-reduction system, it handles slow walking, a light jog or even a decent run while staying quiet. The only real noise comes from your feet striking the running surface.
Set up your desk properly
For comfortable, ergonomic use, pair the Bigzzia with a standing desk. If you don't have one, plan to raise your screen closer to eye level and add a surface for your keyboard and mouse.
This feature genuinely surprised us. 10km/h (just over 6mph) is a strong top speed for a flat treadmill in this price range. Only a handful of machines manage higher speeds while still slipping under a sofa, such as the Gearstone.

The drawback of higher top speeds is portability, as machines tend to get heavier as the top speed climbs. The Bigzzia strikes a sensible balance rather than trying to be best at everything. Most people will find 10km/h is plenty; if you regularly need to go faster, you'd be looking at a mid-range machine, and those typically can't be stored away easily.
Noise is an important factor with any home treadmill, as you don't want to wake half the street for an early-morning jog. The motor here delivers a quieter workout than most home treadmills, and at top speed the majority of the sound comes from your feet hitting the belt. It's quiet enough to watch TV or listen to music at a reasonable volume without straining to hear.
Don't be fooled by the lightweight, sleek design. This is a sturdy machine that handles workouts without hiccups. With any low-cost treadmill there's the worry it'll fall apart after a few weeks, but after 12 weeks of consistent use the Bigzzia held up well. It has a maximum weight capacity of 110kg (17.3 stone).

We had to re-centre the running deck a couple of times, but that's to be expected from most machines. The frame doesn't rock or bend while running, though it feels noticeably more secure on a flat, uniform surface such as a hardwood floor or a mat.
Don't use it on carpet
Bigzzia advises against using the treadmill on carpet, as it affects the machine's heat dissipation. If you only have carpet, a hard treadmill mat underneath will keep it flat, reduce rocking and protect the carpet, but check the manufacturer's guidance first.
A space-saving design has one main drawback: not everyone will be comfortable on a more restricted running surface. Even so, I'm 6ft 3in and had no problem running at full speed. My stride felt comfortable and I never felt like I'd hit anything other than the running deck.

The shock-absorbing belt feels genuinely comfortable underfoot, too. After an hour of running my joints don't feel battered the way they do after running outdoors. The cushioning provides a softer landing for each step, which makes the Bigzzia a great at-home option for anyone looking to improve their fitness.
This is a slim machine controlled entirely by remote, so you can change your walking or running speed without fiddling with on-board buttons. The included remote switches the machine on and off and adjusts the speed.
The LCD display sits at the front and gives you live feedback on speed, distance, time and calories burned. It's bright and clear, but it doesn't do anything clever like tracking your data over weeks and months. If you want to monitor progress, you'll need to jot your metrics down manually.
If you're debating a motorised under-desk treadmill and you're unsure which machine is right for you, you can't go far wrong with the Bigzzia. Its biggest strength is its size. It tucks easily under furniture when not in use and doubles as a desk treadmill while working from home. It's light enough to move around without it feeling like a chore.
The Bigzzia is a well-priced, slim machine with a remote control, an LCD display and a top speed of just over 6mph. It's stripped back, but that's the whole point.
Lift the running belt with your hand and apply lubricant to the underside of the running surface, then repeat on the other side. Turn the treadmill on and walk slowly to spread the lubricant evenly. You'll typically need to do this every 3 to 6 months.
The Bigzzia is controlled by the included remote: use it to switch the machine on, adjust the speed and turn it off when you're done. With no handlebars, it slides neatly in front of a desk so you can get your steps in while working from home.
The Bigzzia is a motorised home treadmill designed for people short on floor space who still want to run or walk at home. Its slim, flat design means it stores under a sofa or behind furniture when not in use, and it has a maximum weight capacity of 110kg (about 17.3 stone).
Press the start/on button on the remote control and the LCD screen at the front of the treadmill should light up. If it doesn't, the machine may not be set up correctly or may have a fault. Contact Bigzzia and they should be able to help.
