WellFit TM015 Review: A Small Treadmill with Proper Side Rails

Compact folding treadmill

Want a treadmill you can leave set up in the spare room without giving it the whole room? The WellFit TM015 makes a fairly convincing case. It has a conventional console and side rails, yet its deck folds upwards into a small standing footprint. At £209.99 before any discount code, that is an appealing combination for everyday walking.

Who does the TM015 make sense for?

Picture a half-hour walk while watching television, followed by folding the deck out of the way. That is the sort of job this machine looks well suited to. The console gives you a fixed place for the controls, and the side rails offer somewhere to steady yourself when getting on and off.

Those rails are a useful distinction from a small walking pad with only a front bar. They do not turn it into rehabilitation equipment, though. The listed starting speed is 1.2 mph (2 km/h), which is worth checking if you need a very slow start.

For a long stride or a proper running routine, I would look further up the range. A belt a little over a metre long gives you less room to drift backwards than a full-size running deck. Buying extra top speed does not solve that space constraint.

A small chassis still needs enough room for your stride

There are two different measurements to keep in mind. The overall 56 cm width tells you whether the machine fits the room; the 40.64 cm belt width tells you how much space your feet have. Those are not interchangeable. If you sometimes catch the edges of a narrow walking pad, the TM015’s side rails will not give you a wider walking surface.

Its 12 km/h maximum works out at a five-minute kilometre. That is plenty of speed for many people, but I would still buy this with walking as the main job. Someone who wants a short, occasional jog has a different brief from someone planning three running sessions every week. For the latter, put more of the budget towards belt length and width.

How the manual incline works

The TM015 offers three advertised positions: flat, 5% and 10%. You choose the setting at the machine rather than raising the deck with a console button. Set it before the session, then walk at the pace that suits you.

That arrangement is perfectly workable if you like a steady uphill walk. It becomes less convenient when your routine alternates between flat and uphill every few minutes. For that, the TM037 Pro or TM007 makes a stronger case because the incline adjustment is powered.

Remember that a percentage incline is a gradient, not an angle in degrees. The figures here are WellFit’s advertised settings; we have not measured the deck angle ourselves.

The folding design is its other big attraction

WellFit lists the open machine at 128 × 56 × 119 cm and the folded machine at 52.5 × 56 × 119 cm. In practical terms, the deck lifts upwards while the console stays standing. That is useful when you have a corner available but little spare floor space.

It is a different storage proposition from the TM037. You gain a shorter footprint when parked, but you cannot slide the TM015 under a bed. Check that its standing position will not block a cupboard, radiator or the route through the room.

The listing describes a hydraulic soft-drop mechanism and transport wheels. Those should help with the folding routine, but we have not measured the force needed to lift the deck or move it across carpet. The 31.5 kg figure on the page is labelled package weight. It should not be presented as a verified net weight.

Controls, motor and everyday use

The conventional console is part of the appeal here. For a quick walk, a visible set of controls can matter more than a long app feature list. The UK page also advertises the free WellFit app and compatible connected features. Paid services from other app providers are a separate question.

WellFit now markets this model with Bosch motor technology and a 3.5 HP brushless motor. We are reporting the manufacturer’s description, rather than treating that horsepower number as a measured continuous-duty rating. How the belt behaves under a particular user and how the machine lasts are things a spec sheet cannot settle.

The supplied safety key needs to be clipped on during use. Keep the area around the belt clear and follow the delivered manual for setup, lubrication and storage. Our treadmill mat guide is useful if you are deciding what to put underneath it.

Why the Bosch brushless motor is a useful inclusion

The Bosch motor technology is a welcome part of the specification at this price. The brushless design is worth understanding too: it switches current electronically instead of using rubbing electrical brushes. That removes brush wear from the list of motor maintenance concerns.

For the TM015’s likely owner, I would put that ahead of chasing a bigger horsepower badge. The aim is a dependable machine for ordinary home walking. You still need to look after the belt and deck, and the brushless motor does not make footfalls on a timber floor disappear. If it will live above another room, placement matters alongside the motor.

The practicalities of owning a TM015

Think through the whole routine before picking a storage spot. Can you lower the deck without moving the coffee table? Can you reach the controls and safety key easily? Is there still a clear route past the machine when it is open? A treadmill that fits neatly into a corner can be awkward to use if you have to rearrange the room every time.

For someone who wants to watch television while walking, I would favour a position facing the screen. Walking while repeatedly turning to look over your shoulder is a poor reason to squeeze the machine into the wrong gap. Mark out the open footprint on the floor, then add the operating clearances specified in the supplied manual. The machine dimensions alone are not a room-planning guide.

The upward-folding deck suits a spare-room corner particularly well. You reclaim floor length between sessions while keeping the console at hand. In a bedroom where the only spare space is under the bed, the flatter TM037 format is the more useful design. This is one of those choices where the room should decide the model, rather than the other way round.

When it arrives, keep the packaging while you check the condition, supplied parts and folding mechanism. Read the model-specific lubrication instructions before the first session and keep the receipt somewhere accessible. Those are small jobs, but much easier to sort out before a large cardboard box has gone to the recycling centre.

TM015 or another WellFit?

The decision is less about buying the most expensive WellFit you can afford and more about choosing the right arrangement of rails, incline and storage. Here is where the TM015 sits.

The standard TM037 is cheaper and folds flatter. It is the more obvious option for under-desk walking. The TM015 makes more sense when you want the standing console, side rails and upward-folding deck.

The TM037 Pro is £90 more at the prices checked here. That buys automatic incline and a lower folded profile, with a very similar advertised belt area. If changing gradients during a session is important, that is a meaningful upgrade.

The TM007 gives you more belt width and length, plus powered incline, but costs £200 more before any discount code. For straightforward walking, there is little reason to pay that simply because its model sits higher in the range.

Where I would spend the extra money

If you want to set a gentle incline once and walk while watching a programme, I would keep the TM015 on the shortlist. Its manual adjustment is much less of a drawback in that routine. If you like changing the gradient repeatedly, the extra £90 for the TM037 Pro buys a convenience you will use during the session.

My reason to step up to the TM007 would be the extra belt space as well as powered incline. Spending more solely for a higher top speed makes less sense when the real question is whether your stride feels comfortable on the deck.

Read the cover behind the warranty headline

The product page advertises a 1-year warranty. The detailed policy lists 1 year for the structural frame but 180 days for other components. Get the UK cover confirmed in writing.

Check the return conditions before treating the 30-day banner as a home trial. These terms do not replace your statutory rights. Keep the receipt and packaging while you check the machine.

Our verdict

A sensible low-cost option for walking and occasional gentle jogging if you want side rails and upright storage. Its short belt and manually adjusted incline are the compromises to understand before buying.

Why the TM015 scores 3.8/5

At £209.99 before any discount code, the TM015 offers an appealing combination of side rails, a conventional console and upright storage for everyday walking. Its short belt, 2 km/h starting speed and manually adjusted incline narrow its appeal. The short component warranty also tempers the value case. We are judging it as a compact walking-first treadmill, rather than marking it down simply for being inexpensive.

This provisional RunRank is our editorial judgement on a five-point scale, based on the documented features, intended use, UK price and ownership terms. It is not an average of customer star ratings. We have not established a substantial body of independent, model-specific owner feedback or tested this machine, so noise, ride quality and long-term reliability remain unverified. Stronger evidence could move the score up or down.
