Motor: 2.5 HP | Speed: 0.6–12.4 mph | Incline: 15 levels | Deck: 150 × 51 cm | Max User Weight: 140 kg | Folding: Yes | Price: ~£899–£949
The Reebok Jet 300 is the flagship of the Reebok Jet series and the best folding treadmill in the entire Reebok range. It combines a 2.5 HP motor, a generous 150 × 51 cm running deck, and 15 levels of power incline into a machine that folds flat when you are finished. No subscription required. No app lock-in. Just a solid, well-built treadmill that does everything most home runners need.
At around £899–£949, the Jet 300 sits in the sweet spot where you are paying enough to get genuinely good hardware but not so much that you are into NordicTrack or Peloton territory where a chunk of the price goes towards a screen and a monthly subscription. Everything you pay for here goes into the physical treadmill, and it shows.
We have tested the Jet 300 against every other treadmill in this price bracket, and it consistently ranks as one of the best treadmills under £1,000 available in the UK. Here is why.

Key Features and Benefits
Motor and Speed
At 2.5 HP continuous duty, this is the most powerful motor in the Jet series. Top speed hits 12.4 mph, comfortably covering walking, jogging, interval training, and full-pace running for the vast majority of home users. Only elite sprinters need more, and they are not buying a standard home treadmill.
What matters more than headline speed is how the motor performs under load. Cheaper motors struggle at higher speeds and on incline, with the belt noticeably slowing when your foot strikes. Not here. The Jet 300 holds its speed consistently. No hesitation on push-off, no surge when you lift your foot. Smooth and predictable, which is exactly what you want when running at pace.
Noise is genuinely low, too. Quieter than both the Jet 100z and Jet 200 below it in the range, and significantly quieter than NordicTrack T Series models at equivalent speeds. If you are running in a flat or a terraced house, that matters.
Incline
A huge 15 levels of power incline give the Jet 300 one of the widest incline ranges available under £1,000. Quick-adjust buttons on both the console and the handlebars let you change gradient mid-stride without breaking rhythm, with shortcut keys for 3%, 6%, 9%, and 12% for fast transitions during interval training.
Transitions between levels happen gradually rather than in sudden jumps. You can ramp the incline up during a run without feeling like the deck lurches beneath you. A small detail, but one that makes a noticeable difference during HIIT sessions where you are rapidly cycling between flat sprints and hill climbs. It makes light work of the 12-3-30 workout or similar programs.
Unlike some competitors in this price range that offer percentage-based incline through a manual lever (looking at you, budget end of the market), every incline level here is electronically controlled. Built-in programs adjust the gradient automatically, creating genuine hill-training workouts without you touching a button.
Running Deck
At 150 × 51 cm, this is the largest running deck on any folding Reebok treadmill. For context, the Jet 200 below it offers 140 × 46 cm — 10 cm shorter and 5 cm narrower. You feel the difference immediately.
That extra length gives taller runners room for a natural stride without shortening their gait or subconsciously holding back. Anyone up to around 6 ft 3 can run comfortably without feeling restricted. Width matters equally. At 51 cm, you have enough lateral room to drift slightly without catching the edge of the belt, removing the low-level anxiety that narrower decks create at higher speeds.
Impressively, this deck matches the non-folding Reebok FR30z Floatride on size. A fixed deck will always have the edge on stability because there is no flex from a folding mechanism, but for most runners the Jet 300 feels more than solid enough.
Reebok Jet 300 Folding Treadmill
- Folds to 124.5 × 86 cm with soft-drop hydraulic mechanism — reclaim your floor space in seconds
- 150 × 51 cm running deck — largest folding deck in the entire Reebok range
- Built-in transport wheels — tilt and roll against a wall, no lifting required
- 87 kg build weight means zero wobble at speed, 140 kg max user weight
- No subscription needed — 24+ programs, Bluetooth, and Kinomap work straight out of the box
Air Motion Cushioning
Reebok’s Air Motion Technology works through eight cushioning pods built into the running deck. When your foot lands, air is pushed through the pods to absorb impact where you need it most, then redistributes as you push off. Straightforward concept, effective execution.
In practice, the feel sits somewhere between a hard gym treadmill and the bouncy softness of some budget machines. Enough impact absorption to take pressure off your knees and ankles, without feeling spongy or unstable underfoot. If you have run on a treadmill where the deck feels dead and unresponsive — or one where it feels like running on a mattress — the Jet 300 lands in the sensible middle ground.
Worth noting: Air Motion is a different system to Floatride+ cushioning in Reebok’s FR range. Floatride+ is more responsive and dynamic, returning energy on push-off for a springier feel. Air Motion is softer and more adaptive. Neither is objectively better — it comes down to preference. Want responsive? Go Floatride. Want comfortable and forgiving? Air Motion is the one.
Console and Programs
A 6-window LED display with a profile chart handles the console duties. Speed, time, distance, calories, incline, and heart rate are all visible simultaneously. No touchscreen, no internet connectivity, no streaming apps. If you want Netflix on a built-in screen, this is not the treadmill for you.
What you do get is clarity. Every metric you need is visible at a glance without tapping through menus or navigating an interface while running. A profile chart shows your workout visually — you can see where the hills and speed changes are coming before they arrive. Simple, effective, no distractions.
Program variety is strong: 24 presets covering fat burn, hill training, interval, long-distance endurance, and cardio. Beyond those, there are 3 user-defined programs where you set your own speed and incline targets, 3 heart rate control programs that adjust intensity based on your pulse, and 3 target modes for distance, time, and calories. A body fat test function rounds it out.
None of this requires a subscription. Every feature works from day one, forever, at no additional cost. An increasingly rare selling point as competitors like NordicTrack and Peloton push harder towards subscription-dependent models where the treadmill is half-functional without a monthly payment.
Connectivity and Entertainment
Bluetooth connectivity links the Jet 300 to the Reebok Fitness App for workout tracking and progress monitoring. Kinomap compatibility adds scenic running routes, multiplayer challenges, and structured training sessions for a more interactive experience. Neither app is mandatory, and connecting costs nothing — though Kinomap itself requires a subscription for full access.
On the entertainment side, you get a 5W speaker system, an MP3/aux port, a headphone jack, and a USB charging port. An integrated device holder above the display fits your phone or tablet, though placing a larger tablet on it will partially cover the top row of the LED display.
An adjustable cooling fan built into the console rounds out the comfort features. Not a replacement for a proper desk fan on a hot day, but a steady airflow during longer sessions that you will appreciate more than you expect.
Build Quality and Stability
At 87 kg, this is a heavy machine. But that weight is a feature, not a drawback. It translates directly into stability: no wobble at higher speeds, no lateral movement on incline, no sense that the frame is working beyond its capabilities. Steel construction with a corrosion-resistant finish feels built to last, and the 140 kg max user weight is the highest in the Jet series.
Folding uses a soft-drop hydraulic mechanism that lowers the deck slowly and safely, preventing the kind of slamming that damages cheaper treadmills over time. Transport wheels at the front base make moving the folded unit manageable, tilt and roll rather than lift and carry.
Floor level adjustment is included for uneven surfaces. A small but useful detail for anyone setting up on slightly uneven flooring in a garage or spare room.
Assembly
Arriving 95% pre-assembled, the Jet 300 needs roughly 10–15 minutes of work with the tools included in the box. Two people are recommended for unboxing and positioning given the 100 kg box weight, but assembly itself is straightforward. Attach the uprights and console to the pre-assembled base, and you are done.
A significant advantage over competitors like the NordicTrack T Series, which can take 60–90 minutes of assembly with multiple steps, calibration, and the occasional wrestling match with heavy components.
What We Like
- Best folding deck in the Reebok range. 150 × 51 cm matches the non-folding FR30z on size. No other folding Reebok comes close.
- 15 levels of power incline. Electronically controlled with quick-adjust buttons on console and handlebars. Smooth, quiet transitions.
- No subscription required. All 24+ programs, Bluetooth, and Kinomap compatibility work without a monthly payment. Ever.
- Rock-solid stability. 87 kg of machine weight means zero wobble at speed. The heaviest in the Jet series and it shows.
- 140 kg max user weight. The highest capacity in the Jet range. Suitable for larger users who are often excluded by the 120 kg limits on cheaper models.
- Outstanding warranty. Lifetime frame, 10-year motor, 2-year parts and labour. No registration deadline to activate it, unlike NordicTrack’s 28-day window.
- Near-zero assembly time. 95% pre-assembled, 10–15 minutes to finish. NordicTrack and ProForm buyers will be jealous.
- Quiet motor. Noticeably quieter than the Jet 100z, Jet 200, and most NordicTrack models at equivalent speeds.
What to Consider
- No touchscreen. The 6-window LED display is functional and clear, but it is not a touchscreen. If you want built-in streaming or a modern app interface on the console, the Jet 300+ variant adds a 10.1-inch touchscreen at a higher price point.
- Heavy to move. 87 kg is stable but heavy. The transport wheels help, but repositioning the treadmill between rooms is a two-person job. Choose your location carefully before setup.
- No decline. Incline only, no negative gradient. This is standard for the price bracket — decline is typically a feature on treadmills above £1,500.
- Folded height is tall. When folded, the unit stands 163 cm high. In small rooms with low ceilings, check clearance before buying.
- LED display, not backlit. The display is clear in good lighting but can be harder to read in a dimly lit room. Not a problem for most setups, but worth noting for garage gym users.
- Kinomap requires its own subscription. The Bluetooth connectivity and Kinomap compatibility are free. Kinomap’s full content library is not. The treadmill works perfectly without it.
Reebok Jet 300 vs Jet 200
The Reebok Jet 200 sits one step below at around £799. On paper, it looks similar — same 15 levels of incline, same Air Motion cushioning, same folding design. But the differences add up fast.
Motor power drops to 2.25 HP, and top speed caps at 11.2 mph versus 12.4 mph. For walkers and joggers, that gap is irrelevant. For runners, the extra 1.2 mph at the top end gives you headroom for sprints and faster interval work.
Where it really shows is the deck. At 140 × 46 cm, the Jet 200 is 10 cm shorter and 5 cm narrower than the 300. Anyone over 5 ft 10 or anyone who runs rather than jogs will notice the difference. Max user weight also drops from 140 kg to 120 kg — if you are a heavier user, the Jet 300 is the obvious choice.
Our verdict: the Jet 200 is a fine treadmill for walkers and light joggers, but the Jet 300 is only £100–£150 more and meaningfully better in every spec that matters for running. If budget allows, stretch to the 300.
Reebok Jet 200
- 2.25 HP motor with 11.2 mph top speed
- 15 levels of power incline
- 140 × 46 cm running deck with Air Motion cushioning
- Folds flat with soft-drop hydraulic mechanism and transport wheels
- Lifetime frame, 10-year motor, 2-year parts and labour warranty —
Reebok Jet 300 vs FR30z Floatride
The Reebok FR30z Floatride is the Jet 300’s closest rival within Reebok’s own range, often available at a similar price around £999.
On pure running credentials, the FR30z wins. More powerful motor (4.0 HP vs 2.5 HP), higher max user weight (150 kg vs 140 kg), and a superior running feel. Its fixed, non-folding deck creates a more stable platform with zero flex, and Floatride+ cushioning is more responsive and energised than Air Motion. Serious runners who prioritise the running experience above everything else should buy the FR30z.
But the Jet 300 wins on one critical factor: it folds. If you need to reclaim your floor space between workouts — and in most UK homes, you do — the Jet 300 is the only option. The FR30z demands permanent floor space of roughly 187 × 74 cm. The Jet 300 folds to 124.5 × 86 cm and rolls against a wall.
Dedicated gym room with permanent floor space? Buy the FR30z. Need folding? Buy the Jet 300. Simple as that.
Where to Buy the Reebok Jet 300 in the UK
Several UK retailers stock the Jet 300, and pricing varies enough that it is worth comparing before buying:
- Amazon UK — Currently around £999 with free delivery. Amazon’s 30-day returns policy gives you a safety net if the treadmill does not suit your space or preferences. Amazon has the best deals more often.
- Sweatband — Typically £899–£999 with free specialist two-man delivery. Clearpay and DivideBuy options available for spreading the cost.
- Costco — Stocks both the standard Jet 300 and the Jet 300+ variant. Costco’s generous returns policy is a bonus. Membership required.
- Reebok Fitness Equipment — The official UK site. Currently showing backordered, so check availability before ordering.
Also worth knowing about: the Jet 300+ variant. It adds a 10.1-inch TFT touchscreen with internet connectivity, Netflix, YouTube, Spotify, and the Reebok Fitness App built in.
Physically, the treadmill is identical. Same motor, same deck, same incline, same warranty. Only the console changes. Argos has previously stocked the 300+ at £749, which is an excellent price if you can find it in stock.
Reebok Warranty
One of the best warranty packages available at this price point:
- Lifetime frame warranty
- 10-year motor warranty
- 2-year parts and labour warranty
Genuinely impressive at this price point. NordicTrack offers a similar structure but requires registration within 28 days of purchase or the warranty downgrades significantly. No such hoop-jumping here — you are covered from day one without needing to remember a form and an arbitrary deadline.
Additional breakdown cover is available separately, typically around £120–£130, extending parts and labour protection beyond the standard 2 years. Whether that is worth it depends on how heavily you plan to use the treadmill, but daily runners putting serious mileage on the belt should consider it.
Support runs through a UK-based helpline and online chat for spare parts and warranty claims. One caveat: the warranty covers domestic home use only. Garages, sheds, and outdoor use are excluded, so keep the treadmill indoors.
Final Verdict — 4.2 RunRank
The Jet 300 is the best folding treadmill Reebok makes, and one of the best folding treadmills available under £1,000 in the UK. No touchscreen gimmicks, no subscription upsells, no features you will never use. Just a solid, reliable running experience on a genuinely spacious deck with enough incline range and motor power to challenge you for years.
That 150 × 51 cm deck is the standout, matching the non-folding Floatride models on size while still folding flat for storage. A 140 kg max user weight opens the door for heavier runners usually shut out by the 120 kg limits on cheaper machines. And a warranty with no registration deadline is a quiet confidence signal from a brand that trusts its own hardware.
Half a point held back because the fixed-deck FR30z is undeniably more stable and powerful at a similar price. If folding is not essential, the FR30z is the better runner’s treadmill. But for the majority of UK buyers who need their treadmill to fold, because the living room, spare bedroom, or garage cannot permanently house a 192 cm machine, the Jet 300 is the one to buy.
Best for: The all-rounder. Runners who want proper speed, generous incline, a wide deck, and no subscription pressure — in a machine that folds away when they are done. The no-nonsense pick for people who just want to get on and run.
Reebok Jet 300 FAQ
Is the Reebok Jet 300 good for running?
Yes. A 2.5 HP motor reaching 12.4 mph comfortably supports running at pace for the vast majority of home users. At 150 × 51 cm, the deck is wide and long enough for a natural running stride up to around 6 ft 3, and 15 levels of power incline add proper hill-training capability. A genuine running treadmill, not a walking machine marketed as one.
Does the Reebok Jet 300 need a subscription?
No. Every feature, program, and connectivity option works without any subscription. Kinomap compatibility is included, but the Kinomap app itself has its own subscription for full content access. You can use the treadmill in manual mode and with all 24+ built-in programs without ever paying a monthly fee.
How heavy is the Reebok Jet 300?
Assembled weight is 87 kg, with a box weight of 100 kg on delivery. Two people are recommended for unboxing and initial positioning. Once in place, transport wheels make it movable by one person for folding and storage, but relocating between rooms is a two-person task.
What is the difference between the Reebok Jet 300 and Jet 300+?
Physically identical — same motor, deck, incline, cushioning, and warranty. Only the console differs. The standard Jet 300 has a 6-window LED display; the 300+ upgrades to a 10.1-inch TFT touchscreen with internet connectivity, Netflix, YouTube, Spotify, and the Reebok Fitness App built in. Expect to pay more for the 300+, though it has been spotted at Argos for £749.
Can the Reebok Jet 300 be used by heavy users?
Yes. At 140 kg (22 st 1 lb), the max user weight is the highest in the Reebok Jet series and one of the highest available under £1,000 from any brand. Machine weight of 87 kg provides the stability to support heavier users without wobble or frame stress. Anyone over 120 kg should choose the Jet 300 over the Jet 100z or Jet 200, both of which cap at that lower limit.
How big is the Reebok Jet 300 when folded?
Folded dimensions are 124.5 × 86 × 163 cm (length × width × height). The deck folds upright rather than flat, so you need ceiling clearance of at least 163 cm where you plan to store it. Transport wheels let you roll it against a wall between workouts.
Is the Reebok Jet 300 noisy?
One of the quieter treadmills at this price point. Noticeably quieter than the smaller motors in the Jet 100z and Jet 200, and quieter than comparable NordicTrack T Series models. Suitable for flats and terraced houses, though a treadmill mat underneath will further reduce vibration transferred to the floor.
What warranty does the Reebok Jet 300 come with?
Lifetime frame, 10-year motor, and 2-year parts and labour — with no registration deadline required to activate it. Additional breakdown cover is available separately for around £120–£130. Covers domestic home use only.
