Our Verdict

The Saris Mag+ is a lower-tier bike trainer that will get you up and pedaling without much hassle or cost. It's not going to compete with top-end smart trainers, so don't expect to get the best, most immersive experience out there, but do expect to be able to get in some good workouts when the weather's not great, or your schedule doesn't allow you to ride at ideal times. It's durable enough, and Saris has robust customer service if you need it.

Bottom Line A simple, no-frills tire-drive trainer that gets the job done for lessEverything you want in a premium direct drive trainer for less than the high-end competitionThis trainer brings premium performance to a more affordable price pointOne of the best tire drive trainers, but still not as good as a direct-drive unitA super affordable but unrefined trainer for infrequent users

Our Analysis and Test Results

To get the low-down on the Mag+, we spent hours in the saddle and just as long behind the computer researching materials, design, and claims to validate or debunk. We tested both individually and alongside other top trainers to bring you the details that matter.

Connectivity and Power Accuracy


The Mag+ isn't going to get many points under this measure because it's not a smart trainer. It does get credit because you can find good power curve charts on the Saris site. We were able to validate that against our power meter. Using an aftermarket speed sensor, we also easily found it on Zwift and could sync for a slightly more accurate ride. However, it's still not true connectivity because the training programs were running off of our speed sensor (not included with this trainer), not the trainer. If you purchase and install a speed sensor separately, you can also connect to other popular third-party apps, but you'll still have to control the resistance.

Road Feel


Magnetic trainers don't do an excellent job of simulating the road (until you get to the high-end direct-drive trainers). The Mag+ is no exception. The drum is way too smooth, and the inertia you get from the small flywheel just isn't there. This is why we suggest that this trainer is ideal for getting the legs spinning but may be less suited to serious training workouts. You get a small degree of flexibility or workout versatility with the five levels of resistance adjustment, which helps. Still, you're going to struggle with workouts requiring lots of standing, sprinting, or quick changes in output.

Design


We think the design is pretty good for what it is (a low-cost magnetic trainer). It's durable, made with tough materials, and gets the job done. We've heard complaints about the drum on the resistance unit wearing out over time, but we couldn't validate that or find good evidence for it after a few months of use. We notice that it is quite loud, which Saris explicitly says is not the case. Perhaps they can work on that.

The only other areas that stood out were the shifter cable and the small flywheel. The flywheel is so essential for these trainers to deliver an adequate road feel. The Mag+ flywheel is probably only 5 or 6 pounds. Future iterations might up that a bit. The shifter cable is also an area that could see improvement. Getting the cable set into the resistance unit was a pain, but getting it attached to the handlebars and using it was…silly. It's not the most stable mount, and there were a few times when we were in the middle of a workout segment and we lost the shifter mid-shift. We think this is an obvious area for easy improvement by Saris.

Setup


We wish Saris would put just a bit more effort into this area. That's not to say that they don't make an effort, only that they could improve the setup process. The most annoying thing to us was the assembly of the resistance unit. It was easy enough to affix it to the stand, but getting the resistance cable aligned with the internal components and keeping the tension on while stretching it out was a pain. Not impossible, but it takes a few minutes of unexpected tweaking and tedium.

Sure, it looks simple now that it's here in the picture, but it takes a little too much screwing around with cables and holes to figure it out. Hopefully this is...how it's supposed to be assembled...

Portability


The Mag+ is a fairly lean model that breaks down neatly, so stowing it is pretty easy. You can even remove the resistance unit and stuff it all back into the compact box Saris ships to keep everything together and bound up. The only annoying thing is the resistance cable, which you'll have fun folding and keeping stowed up. It's excellent for any OCD or Type A people.

Should You Buy the Saris Mag+?


While not a perfect bike trainer, we think this little gem is enough to get you moving for inside training ithout the frustration of buying a lemon or something you won't want to use. While we understand the draw of a budget-friendly option and that some are looking for wallet-friendly options, there is no point in spending any money on a product you'll never use. We think most of the inexpensive options will likely gather dust in the corner for years before finding their way to the local Salvation Army. The Mag+, however, has potentially hit a sweet spot of being reasonably priced and not frustrating. So depending on your needs and how much you have to spend, this could be the one for you. It is the best of the basic models with a price reasonable compared to the more advanced competition.

What Other Bike Trainer Should You Consider?


If you want the best trainer and money isn't a huge factor, then the Tacx Neo 2T Smart is the one you want. It earned the highest overall score and the best road feel and connectivity results. If you like Saris or want something a little less expensive, the Saris H3 Direct Drive offers everything you want without the high, high price tag. If you have a tight budget and aren't sure you need all the bells and whistles, you should consider the Wahoo Fitness Kickr Core, an affordable option with excellent features.
