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.

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.

Funciona sin problema, un poco ruidoso en ocasiones dependiendo de la resistencia y los cambios que hagas pero nada que no pueda tolerar. Estoy satisfecha con mi compra

Viene armado y listo para utilizarse, se ajusta perfecto a la llanta de la bicicleta y queda firme, aún no he probado los niveles de resistencia más allá del 3 pero si se siente el cambio al pedalear. Ocupa poco espacio tanto desplegado como para guardarse.

No me gusto nada del artículo

Me gustó mucho y lo he encontrado bastante útil me ha servido para el propósito de ejercitarme un poco en casa. Se siente muy bien es de buena calidad pero si hace mucho ruido, nada que no arregle unos audífonos

Muy buen producto, la construcción es fuerte, el modelo azul incluye una base para la rueda delantera y un controlador de resistencia por cable, del cual el control se puede montar fácilmente en el manubrio de la bicicleta. Debido a que la bicicleta es de ruta, la rueda no hace tanto ruido al rodar sobre el rodillo del soporte. Lo único que no me pareció tan bien es que el manual es demasiado simple y le falta explicar algunos detalles, por ejemplo el ajuste del rodillo, pero como el equipo es tan sencillo es fácil deducir cómo hacerlo.

creo q la relacion precio calidad del rodillo es buena, cumple con su proposito. buenisimo el sistema de bloqueo muy practico, y el ajuste para la rueda y que te incluye el block para rueda delantera. unicos detalles, un pococ ruidoso para mi gusto y que los niveles de resisitencia son poco percepetibles en los primeros. pero buen producot en gral. satisfecho

He usado por 3 semanas el rodillo y funciona a la perfección. Es importante saber que NO tiene control remoto de resistencia, por lo que deberás usar una bicicleta con cambios. En mi caso utilizo una algo antigua de montaña con relación 3X7 cambios, rodada 26. Si no tienes una bici de velocidades mejor compra un rodillo con control remoto.OJO, si usas una rueda con "tacos" hará mucho ruido, como cualquier rodillo. Es MUY IMPORTANTE poner una rueda lisa, sin ningún dibujo y evitarás el ruido al 100%, además que no se desgastará a la velocidad que las otras. Coloqué una rueda muy delgada de bici de ruta, que incluso me la regalaron en un taller.El material con el que está hecho es muy resistente y bien vale la pena el precio.Les puedo recomendar para entrenar buscar rutinas de spinning en Youtube y uso de pulsometro.

Great indoor trainer for the price. I looked at various bike shops and they only carried certain brands that were too fancy for what I needed and definitely beyond my price range. I easily and quickly fixed my bike to this and it has been a great way to watch TV guilt-free! The only problem I had was the gear mechanism was too small to fit around my handles so I had to attach it with an elastic band. Other than that, I would recommend this product to friends.

Bottom line:I would recommend this product to a friend. Superb product considering this is a economy bicycle trainer.Background:I have used Minoura trainers in the past and Minoura is the only thing I can compare this trainer against. This is not a Minoura, nor is it priced like one. I used to cycle and compete in races. I have been off the bike for a 5+ years and have been interested in getting my cardio back up, using a trainer as at-home gym system.Noise:I was a little hesitant about this product, knowing how much noise a trainer can put out! I was pleasantly surprised with this model though. I use mine on a carpeted floor, so I can't comment on frame vibration, but for the most part this trainer is quiet - the noise put out by the bike's chain drive is louder than the trainer. Noise levels increase at position 1 a little bit, but the noise seems to subside as the trainer heats up with use. Considering this is an economy model, I am pleased with sound output. I can watch netflix on my computer while on the bike, but I find it easier to enjoy with subtitles on due to noise. Not much louder than my Minoura from the past.Build:The skewer provided with the trainer makes any bike compatible with the unit and allows for better lock in. The threads of the lock in mechanism are rough, so there is a little wobble when all locked down. Nothing I am concerned about. I have used the trainer now for ~10-15 hours in 30-50 minute workout sessions. No issues so far!Ease of setup:No instructions. Simple design, so you shouldn't need them. No tools needed for assembly.Overall:As a 150lbs ex-cyclist, this has been a great way for me to start getting back into shape. An at-home cardio system that allows you to watch netflix while you workout; it's a great inexpensive workout! After about 25 half hour workouts I am only pushing resistance level 2-4. This is with my regular road riding gearing allowing me to achieve 28km/h @ 110 rpm cadence. If you're a 300lbs athlete, resistance might feel a little light for you. If you've never cycled before, resistance level 1 may seem pretty high. I think resistance is geared towards the weekend-warrior cyclist, which is exactly what I wanted, and likely what you're looking for too.

Arrived the day promised. Set up was a snap. It comes with a quick release shaft for the rear axle. My old Trek Antelope doesn't have a quick release on the rear wheel. Wasn't a problem. The hub end cups on the Rad trainer fit nicely over the nuts on my axle (these nuts are 12mm across the flats). Once I tightened things up, the bike felt rock solid on the trainer. The handles you use to tighten things up are made of plastic, pretty sturdy plastic. I suppose you could break them if you tried to, but if you keep in mind that they are plastic, and can't be tightened as far as steel can be, you'll be fine.First ride was 40 minutes. Hardly any noise from the device. I probably have it set up pretty optimally for quietness. It sits on a welcome mat sitting directly on the concrete slab in my home, and I have street slick tires on the bike. I turned the TV on for a bit, barely heard the trainer then. It gives me plenty of resistance for burning calories/aerobic workouts, but is not going to please anyone who wants a trainer that will simulate steep hill climbs. I doubt there is any trainer for less than $300 that will do that. I'm very pleased with it.The only real problem is now I won't be able to use the weather as an excuse for not getting in a workout.
