Best cheap smart trainers 2025: get connected without the cost

One of the best cheap smart trainers will kickstart your indoor training without the expense of many of the best smart indoor trainers or best indoor smart bikes, and it is certainly much easier to get the hang of over the best bike rollers.

As indoor cycling has become more popular, trainer makers have trickled their technology down to lower price points. Once a premium product, the best budget smart trainers now offer similar functionality at a more reasonable price. A prime example of this is our best overall direct-drive trainer, the Tacx Flux S, which far surpasses trainers that are twice its price.

Indoor cycling doesn't just allow you to avoid the weather; it offers many other advantages, such as a more controlled environment where you can concentrate on your riding, not the traffic. Now, with the best indoor training apps, the experience is a lot more immersive, letting you ride with other cyclists online.

The best cheap smart trainers come in two main varieties: wheel-on and wheel-off, also called direct-drive. As the names suggest, wheel-on places the rear wheel onto the trainer, and the tyre runs on a roller connected to the flywheel. Wheel-off or direct-drive mounts your frame directly onto the trainer, allowing for a more accurate transfer of your effort. Why not check which style might be best in our wheel-on vs. direct-drive comparison guide?

The Quick List

Best cheap wheel on & direct drive turbo trainers

Best wheel-on overall

It seems a bit unfair to compare a wheel-on smart trainer to its high-end direct-drive stablemate, but the specification and performance of the Wahoo Kickr SNAP make it hard not to do so. After all, maximum power of 1,500W and a 12% simulated incline are figures that are much more usually seen on direct-drive machines.

The SNAP has a great planted feel and is one of the smoothest wheel-on trainers we've ridden. No, it's not as smooth as a direct-drive turbo but that's a small price to pay given it retails at a third of the price.

At low powers we found the accuracy to be less than the claimed +/- 3% but this improved at higher intensities where these things matter more. Power readings can be a bit spiky, although this largely seemed to be due to an absence of excessive smoothing that more expensive machines are capable of rather than a variation in resistance. There's also a bit of a lag in resistance change at the turn of programmed intervals which we've picked up in other similar-priced machines.

Best value direct drive trainer

The Wahoo Kickr Core and Tacx Flux S present an intriguing contrast, resembling a Venn diagram where only a thin sliver represents their differences. Despite their similarities, both models excel in fundamentals, so it’s essential to explore their key distinctions.

Regarding ride feel, the Core outperforms even the flagship Kickr V5 I tested last year (now surpassed by the Kickr V6). This could be due to the flywheel weight. With its significant inertia, the Kickr V5 often felt like riding a ‘spin bike’ rather than on an open road.

The Kickr Core has a 5.4kg flywheel compared to the 7.3kg of the V5, making acceleration feel more natural. However, heavier riders might experience otherwise.
In response to sudden gradients and power changes in ERG mode, resistance adjusts smoothly and quickly, without forcing a lower cadence like the V5.

The Kickr Core addresses the shortcomings of the Tacx Flux S. With ±2% accuracy, it offers an affordable entry into high-end indoor racing. A maximum gradient of 16% lets you tackle Alp du Zwift and feel every ramp. It’s also more portable and space-efficient than the Flux S. However, it lacks stability compared to the Flux S, which is notably solid due to its three-leg design.

Best overall direct drive trainer

This indoor trainer is great but not for everyone. Here are the details: With the heaviest flywheel, the Flux S is the heaviest overall. Its unique footprint offers incredible stability, possibly even more than the Tacx Neo 2T I tested last year. Additionally, the resistance and ride feel are impressively close to Tacx’s flagship model. Gradient changes are fast and smooth, and resistance remains steady even at low speeds and cadences, making it a challenge for a trainer.

The ERG mode handled large power differences effectively. Resistance increased quickly, but not as dramatically as the Elite Zumo. When riding without ERG or virtual gradients, I maintained a comfortable cadence at 250w with plenty of gears left – no risk of spinning out. Regarding virtual ride feel and turbo stability, this was the best tested, surpassing even pricier models like the Elite Direto and Wahoo Kickr, which we’ll discuss later. Having covered the basics, it’s worth considering if there's any advantage to pricier models. Unfortunately, yes, but only for specific use cases.

First, accuracy is rated at ±3%, the same as the Zumo, but it falls short of the ±2% standard for top Zwift racers. This is irrelevant for most users, as few race in those categories. For virtual challenges like ‘everesting’, realism must be at 100%. If using Alpe du Zwift, you'll violate this rule due to its max gradient of 14%. While these limitations don’t concern most users, being aware of them is important to avoid surprises, even though this trainer remains our top recommendation.

The other consideration is that this is not a trainer for moving about or stowing away. The legs don’t fold and it is really very heavy.

Best budget direct drive

If all you saw of the Van Rysel D900 was its spec sheet, you would be forgiven to think it should be a price twice what it is. Decathlon (owners of the Van Rysel brand) had one clear objective with the D900, to take on the Wahoo Kickr and Tacx Neo 2T but at a much more affordable cost.

Initially, during our testing, it seemed like Decathlon had hit the nail on the head. The D900 feels very stable and jumping straight into both ERG and SIM modes proved it had what it took to compete. Once I started digging down into the details, that's when I started to see why the D900 is so much cheaper.

After some cross-checking with my 4iii dual-sided crank-based power meter, it appeared the power accuracy wasn't within the +/- 2% Decathlon claims. My testing shows it was actually nearer +/- 12%. Which in my experience is unusual for a power meter based at the hub, as they tend to read much lower. Fortunately, despite the discrepancies the data is consistent. So, with a little bit of maths, you could continue to track your progress and performance.

The Van Rysel D900 does what it set out to do, compete with the best. Assuming don't mind the occasional bit of maths or take your E-racing too seriously. I think the one bit of maths we can all do though is the cost saving over the Wahoo and Tacx.

Best value wheel-on trainer

The Tacx Flow is easy to set up, lightweight and can be used unpowered for warm-ups at events. It's very stable, with wide legs and it offers BLE and ANT+ connectivity to transmit speed, power and cadence data to a head unit.

We found that there's a bit of a lag in ramping up resistance both when controlled by Zwift and using ERG mode, which can result in sudden increases when performing certain workouts.

The wheel-on design gives you more limited climb simulation than a direct drive unit at up to 6% and the maximum resistance is 800 watts, with an accuracy of +/- 5%, although we found the Tacx Flow read lower than comparison power meters.

Best compact wheel-on trainer

With wooden legs and a square drive unit, the Elite Tuo looks smarter than most trainers. It folds up very small and is lightweight. It's easy to set up your bike on the trainer and thru-axle adapters come with it rather than being an extra.

Elite claims power accuracy of +/-5 per cent, with simulated gradients of up to 10% and 1,300 watts maximum resistance. We thought that the ride was very smooth, with no skips from the roller and power and cadence were accurately measured except in short, high-power sprint efforts.

How we test

The Cycling Weekly team has logged hundreds of virtual kilometres on all the budget-friendly smart trainers showcased in this buyer's guide. The overall rating considers factors such as ease of setup, how well the units connect with apps like Zwift, overall specifications, and how easy they are to store and transport.

We evaluate these trainers over multiple indoor sessions. This provides insight into their performance and allows us to assess their accuracy in replicating sessions and data. Our findings are then verified against a power meter or other home trainers for comparison.

While our primary testing occurs on Zwift, providing consistent reference points, we also test compatibility with other third-party indoor cycling apps where possible. Most importantly, and albeit subjectively, we attempt to express the idea of 'ride feel'—how pedalling feels on the trainer across a range of efforts. This aspect, perhaps more than any other, influences the enjoyment of using a trainer.

How to choose a cheap smart trainer

The first question you should probably ask yourself is whether you need your trainer to be smart and offer connectivity. If you are looking for something to just spin your legs during warm-ups and cool-downs, then certainly consider some of the best bike rollers over a turbo trainer.

If you want to add structure to your training and maybe even race, then a smart trainer is exactly what you should be looking for.

Is wheel-on or direct drive better?

The cheapest smart trainers are usually wheel-on options. They have the advantage that you can just anchor your bike in the trainer and start to ride with very little intervention from you. Among their disadvantages is that the trainer can wear through a rear tyre quickly, so you may need a harder compound indoor cycling tyre. The power measurement is likely to be less accurate than a direct-drive model, too.

A cheap, direct-drive trainer will give you more reliable power figures. Although it probably won't be as accurate as premium models. For most, a figure of +/-3 per cent in power readings isn't going to make a lot of difference to your training or racing, but you might have to do a little math just to make sure you stay on track. Some mechanical intervention is needed, though, and this might be daunting to some. You will need to buy a cassette and fit it, as well as remove the rear wheel and make sure it's fitted in the trainer correctly, but you'll save wear on your rear tyre.

So, it will very much depend on your circumstances. Our advice is that if you have a second bike or don't plan on using the trainer much, a wheel-on system can be much cheaper. However, if you are inclined to spend a winter sweating it out in your shed, a direct-drive is a must.
