  • Updated frame works with all standard wheels and now works with 29er mountain bike wheels (fits most treads to 2.25 in.)
  • No manual adjustments needed; simply shift gears as you would when riding outside to increase or decrease the resistance, and the faster you pedal the harder it gets
  • With a quick load cam lever, you simply adjust the resistance once and then lock it into place so there is no guessing each time you put your bike on the trainer
  • With a smooth, quiet ride, locking bolt ring and heavy-duty steel construction, you're ready to sprint, spin and climb with confidence
  • The Cyclops Magneto bike trainer features adjustable foot pads, a quick release handle, self-cooling mechanism and folding legs for storage

Rated 3 out of 5 by from Excellent While it Lasted I had a CyleOps Magneto trainer for about 6 weeks. As time went on it got noisier and noisier. Finally I took it back to the local bike shop where I bought it and upgraded to the Fluid2 with a full credit for the Magneto. The bike shop agreed that something was rattling around badly inside and the noise level was way too high. While I was using the Magneto (and while it was still quiet), I liked the ride, very road like, and the gears adjusted the resistance very well. I originally got the trainer shortly after having knee surgery and needed a way to exercise without putting stress on my knee. The Magneto filled the bill.

Rated 4 out of 5 by from Great product and workout so far A "requested" gift so I could get more excercise in my limited time. I used to be an avid cyclist but haven't really ridden much for 10 years. This trainer was very simple to set up, I can move it around with ease, fit my 25 year old road bike with no problems and seems to work very well, including providing progressive resistance when called for. My only dig would be to include a more recreational training/workout video as well or instead of the racing oriented video. So far I can barely get through the warmup portion of the racing video and am already looking for more recreational videos to ride with.

Rated 4 out of 5 by from Easy to use trainer The unit is very easy to set up. The assembly instructions could use some improvement however, those are really used once and the retailer should be able to provide the help needed. Putting the bike on the trainer is quick and easy due to the quick lock handle. Fit and finish was very good on the metal components but, the sticker decal on my trainer is starting to lift off. That may concern some and others won't care. It does not affect the performance of the unit. Overall, a very good bike trainer that is easy to set up and easy to use.

Rated 5 out of 5 by from Can't beat it for the price I've owned this for several years now and it's still going strong. For the price, you get a smooth, quiet, stable and long wearing trainer that isn't so heavy that you'll never take it to a friends garage for a group workout. Even the CycleOps support is awesome - over one summer some parts disappeared and it was easy to find replacements. For the price - you just can't beat it.

Rated 5 out of 5 by from Magneto Trainer works for me I use the Magneto to do routine exercise indoors, while reading. I set up a music stand to hold reading material, and make productive use of time that would have been spent just reading like a blob at my desk to also get in an adequate cardio workout. I've been off the bike for a few years, and I am stunned how just a few weeks back in the saddle have improved how well I feel. Time required for work related reading is no longer an obstacle to fitness, because I can handle both simultaneously using the Magneto with my dusted-off bike.

Rated 5 out of 5 by from High quality product and great customer service I originally ordered the Mag Trainer and there was defect in the resistance weight. The customer service made up for this 110% and sent me the resistance weight that upgraded my trainer to the Magneto. I've used this several times now and love it. It's very sturdy and a high quality piece of equipment. I break a decent sweat with a 45 minute ride. I needed something to help lower my cholesterol and stay in shape during the winter months. It's well worth the investment because I know I will get a solid workout for years to come.

Rated 3 out of 5 by from Solid Entry Level Trainer I like the trainer so far. It is easy to use and the resistance is pretty road like. I would like more detail on the resistance curve versus wheel speed to get a better idea of the power output I am riding at since I do not have a power meter.

My Magneto is 2yrs old, light use, on a newer GMC Denali 6061 (only used indoors). At avg speeds trainer produces low-pitch 'thumping' sound that inc/dec w/ speed (in addition to normal tire-on-drum noise). What causes this? Am I damaging the unit?

​To properly diagnose the issue we recommend taking a video or audio clip of the noise and contacting CycleOps directly.
