Max Racer 7 Levels of with Smooth Magnetic Resistance Bicycle Trainer Allows You to Work Out with Your Bike

Pull that derelict 1990s mountain bike out of the garage and put it to use! So many people throw away old bicycles. Either pull one out of your garage or basement, or find one on the side of the road on trash day and mount it up to this trainer. Give the chain a quick oil. Replace the tires with cheap road tires and you are good to go with an inexpensive exercise bike! The good: I am mechanically inclined. I didn't even need the instructions or a video. I had this unpacked and my derelict bike mounted in 5 minutes. The resistance unit comes pre-mounted to the frame. No tools needed. My bike has a 15mm axle nut. Which is very standard. Not a quick release. The cups fit right over it nicely. Using a set of measuring calipers, the cup is 17mm inside diameter. Which means if will fit a wide range of axle nuts from 15mm, 3/4" and 5/8". Again, if your bike has a standard axle nut and NOT a skewer, this should still work fine. My bike also has rear suspension via a floating rear fork. It's fine. Very sturdy. Though I can't say that it will work with any bike having suspension. There will be weird side/twist forces the fork, so I wouldn't recommend it for a flimsy bike or one you care about. There are four wing nuts on the axle clamp adjusters. These were surprisingly made of metal. Possibly pot metal but way better than plastic ones on competitor units. Pleasant surprise. The outer one controls the tension on the axle nuts. You want to tighten these down with cups over the axle nuts so the bike is centered. Hand tighen until the bike doesn't wobble side to side then go another 1/2 - 3/4 turn. Then use the inner wing nuts to lock it in place by tightening them down against the frame of the trainer. The plastic riser block is included. Remember to throw that under the front wheel. Pro tip #1: invest in a more comfortable seat no matter what bike you use. Pro tip #2: by a cheap digital speedometer that mounts to the spokes. Then you can track speed and mileage of your workout. Pro tip #3: put this in room with a smart TV or mount a tablet on a music stand for entertainment. Or maybe use your favorite cycling app. It may not replace a full blown guided workout on a pro bike but you can use your imagination and stay entertained. The challenges: The resistance unit is cheap and has a tiny flywheel. This means it doesn't regulate speed very well. Don't use knobby tires. Road tires will still be noisy but honestly not much noisier than other cheaper exercise bikes I've used. A large knob screw is included in the kit. This threads into the resistance unit to control how much tension is placed on the tire. Rotate the pedals by hand and tighten the knob so the roller doesn't slip on the tire. But not so tight that it causes too much deformation of the tire. Deformation means excess friction, heat, noise and wear. Ideally you don't want any deformation at all. But you may need some to prevent it from slipping at higher speeds. Keep road tires inflated to max pressure on the side wall. Rubber pieces/dust may be shed due to friction. So keep a throw carpet or mat under the bike. Run the cable loose to the handlebars. Do no twist or bend the cable. Do not wrap it around the frame. Put bike in highest gear. On mine, that means the largest front sprocket, and smallest rear sprocket setting. This makes the resistance much more reactive than using a lower gear. Depending on your bike, it may be too reactive. Try the next gear down until you are happy. Too low of a gear will offer too much mechanical advantage and won't feel like a challenge at all. I did not test this with a single speed bike. But the resistance unit might not offer enough load for a single speed bike. In that case, consider the brake mod below if you have hand brakes. Potential improvements: I ordered a set of "felt/wool" brake pads. I'm going to dispense with the resistance unit and modify my rear rim brakes to use felt pads. I already tested riding it this way with the stock brakes. In the highest gear I only need to hold the brakes on a tiny bit to feel reasonable resistance. I am able to do an entire workout this way, just regulating the brakes with my hand. Once I get felt pads, I will just use a zip tie or rope with a slip knot to control resistance. A little silicone spray on the felt every few weeks will make it quiet. I expect this approach to be more quiet and reliable than the included resistance unit. Summary: Overall I am very happy with this trainer stand. Wayyyy better than an overpriced $XXX (or $XXXX) stationary or spin bike, and helps keep derelict bikes out of the landfill. Or puts your existing outdoor bike to good use in the winter. I got the red unit -- on sale. Can't beat the price. I couldn't build one out of wood or with jack stands for this price, even if I toss the crappy resistance unit aside, it's still a bargain. I'm sure it will fit most 26-28" tire bikes just fine. Regardless if it has a quick-release skewer or old-fashioned axle nuts. It may even fit an ancient 29" 10-speed if you do the rim brake mod I referenced above and delete the tire and resistance unit. The stand alone is worth the price. Your own imagination is the limit. I may even consider using the stand for a custom generator project to make electricity with it someday. Hope this review helps someone.

I purchased this 7/23/2025 for $35 and opened it up right away and sat it in the corner of my basement gym. I just brought my bicycle in from outdoor storage today and set it up on this trainer. I have an approximately 2021 TREK FX1 XL Frame (22.5/60cm) my tire treads are 35x700 (1.375" x 27.56"). I have a small luggage rack on the back of my bicycle. I was able to clamp the rear of my bicycle into the frame of this trainer without even removing my axle or one nut. I did remove my kickstand but am now thinking I probably could have left it on. The resistance dial looks neat but seems useless, I cannot determine if it is providing any difference in the resistance from the trainer. There is some resistance from the trainer and utilizing the gearing on my bicycle provides way more than enough range of resistance (as others have said, and as makes sense). I'm gonna stay right in the middle of my gearing the entire time I use this. It does make some noise, there is an adjustment knob on the rear to press the steel roller up against the tire. Get it right and the noise is not too bad and the bicycle will pedal very smooth. Too tight and it will make much more noise and won't pedal as smooth. The difference is not very much. Its easy to adjust, just tighten it up a bit and back it off until it feels right. Now that I have it adjusted right the noise will be tolerable, no more than the noise of my treadmills, with my ear buds in I doubt it will affect my ability to watch movies on my gym TV. So far everything feels very solid but all of the hardware is obviously lower grade, I feel I could easily overtighten and strip stuff, so just use common sense. I weigh 270lbs (5'11" with a basement full of weights a couple treadmills) and I sat on the bike and used it and the rear of the bike feels very steady. I put the front tire holder on a couple pieces of plywood to raise it 1.5", I have a small TV higher on a wall I want to be able to view without arching my neck. The tire holder itself is perfect for my tire. My long torso and moderate height put me in between a large and an extra large bicycle frame. I prefer the XL frame to the L frame. I can just barely get on and off my XL while on the street. Mounting it into this trainer raises it an inch, I have a step stool I'll keep next to this rig. This is my first trainer, I quickly learned the bicycle will not be able to swing side to side at all, so be aware of that. Four stars because this trainer is very inexpensive $35. Clamped to my bicycle extremely easily. Works as intended. Of course I would prefer a $300 one. This was an experiment to try a bike in a corner of my gym. It will serve that purpose wwonderfully. I will use it. I already have. I think I might prefer an airdyne to an exercise bike. This $35 helped me figure that out. ANd I can use my bike while shopping Marketplace for that Unicorn of a deal on an as new Airdyne. If you need one of these and budget is an issue but this one, it works.

I was extremely impressed with the quality of this budget trainer, especially for the price. This is my first bike trainer, so I don’t have anything to directly compare it to, but it absolutely gets the job done. I hooked up a Garmin speed sensor and was able to connect to cycling games, which makes indoor training much more engaging and practical. The resistance feels smooth. The frame is made of sturdy metal with some plastic components, and it feels solid when in use, no wobbling or instability. It was very easy to set up.

Item arrived today, easy assembly. Having done some due diligence regarding noise/vibration issues I purchased a slick tire with no tread via amazon which also arrived today and installed on my 90s Honda mountain bike. The frame skewers accepted the nut which is under 15mm no problem. Rode about 3 miles, slight tire noise but nothing overly obnoxious that my music couldn't drown out. Resistance settings are okay but can be adjusted with gears as well. Seems to be a well built product and the price is nothing to complain about in the least. Recommended.

Iwavered between a 3 and 4 star. My wheels are 700c. It does not clear the floor, so I had to put it on top of some sturdy corrugated plastic sheets I had. I did not change out the axel. It fit just fine on the nuts that were already there. It is not overly heavy, but appears sturdy and was pre-assembled. Easy to install. The tensioner does nothing. I won't be taking any spin classes with it, but it should give me a decent cardio when the weather is yuck. The price was good for my needs.

This is an excellent tool for people who wanna exercise and don’t wanna leave the house. The only thing you have to do is bring your bike inside the house. It made my life so easy.

Excellent. J'ai reçu le colis sans problème. La boîte était intact. En ce qui concerne ce produit, je suis très satisfait. Il ne fait pas pour les fat bike, mais je l'ai acheté pour un vélos normal de 26 pouces.

For indoor exercise

Super agusto, lo uso casi todos los dias, me encanta que tiene diferentes resistencias y no tuve que hacer nada para esto ya que viene el cable directo al rodillo. Feliz con mi compra

Received the product QUICKLY! My initial observations after unpacking where that it came as advertised, complete with front wheel block and quick release axle. The weld quality looked good as did general paint, fit and finish. I would have liked to see metal "Quick nuts" on the threaded axle clamps but the plastic ones seemed robust enough. I am 6'4", 230 lbs and ride a hard tail Norco XFR with a 20" frame and 28" wheels. For indoor trainer use, I swap out the rear wheel for a skinny, 26" one that comes off an old road bike with the skinniest, smoothest tire I could find. Those of you complaining about noisey indoor trainers, if you do this, it will cut your noise by at least 75% or more, over the knobby MB tires. There was plenty of adjustment, via the simple, threaded adjuster to compensate for different sized wheels and tires and it took only about 15 minutes to get the bike set up and ready to ride. Initially there was some noise out of the unit itself, in addition to the regular tire noise but the longer I rode, the less the noise. Perhaps this was just some initial break in noise, time will tell. Even though my bike and I are both oversized, the unit held the bike fairly steady with only a little flex, mostly when on the pedals hard, in high gear. I would say that the resistance adjustment was OK, but I would have liked to see a greater range of resistance. After a short, 25km ride at a moderate to fast pace, I observed no heat buildup in the unit. Overall, seems to be a good trainer for the price!!!!

Me encanto el producto, lo escogí por que tenía buenas reseñas y no se veía tan “generico” como otros modelos y no decepciono. Los materiales son de buena calidad, sobretodo la calidad del metal y la pintura es sobresaliente y se ve que es muy resistente y durable. En cuanto al funcionamiento yo le instale mi bici de montaña y también la de mi esposa y ambas se ajustaron perfectamente, es cierto que hace algo de ruido sobretodo con la llantas de montaña, lo cual es normal, pero a la tercera sesión de uso te acostumbras. Tardo aprox días en llegar pero vale la pena el producto, no van a encontrar un mejor modelo como este por el precio.
