  9. WHICH BIKE TRAINER IS RIGHT FOR ME?

    When in the market for a new indoor bike trainer, the most important question to ask yourself is: what are my goals? If you don't have specific goals in mind, perhaps ask yourself what you're looking for in a trainer.

    Maybe it's the ability to sit, spin and catch up on Netflix. Maybe you're training for a race or have specific workouts in mind. Maybe you want to join a group ride on a cycling app.

    A clarifying point: indoor trainers may also be referred to as a turbo or a turbo trainer. So if you're in the market for a turbo trainer, you're in the right place!

CycleOps - Think twice!
At first, the trainer worked very well. However, about 2-3 weeks later, I could not pedal and popped my chain when I tried to calibrate the trainer. I received minimal support from CycleOps because the staff, albeit friendly, work Mon-Fri 8-4:30 CST. I work too! I cannot take off work to calibrate the trainer with Tech support. The company must have sensed an issue, so they released a firmware update recently. Unfortunately, it did not work for me. I returned the trainer. I am waiting for my refund to purchase a different brand smart trainer.

5.0 out of 5 stars Great for Zwift (Update 5 years later)

Takes a bit of work to get setup but works great once you do!

I’ve used this with Zwift for over a month now without issue. Be sure to clean your tire first and check for rocks so you don’t blow your tube.

Updated review below:
-----
After using this trainer for over 3 years I can still say it's holding up extremely well. I have had no problems with this trainer.

The trainer itself has minimal wear and tear and I have put thousands of miles on it. It's very important to keep the firmware updated on this unit (use the Roovy app) as well as calibrating the spin down (with Roovy, not Zwift). Always make sure your tire is 100% clean before putting the bike on the trainer. Because there is so much pressure that's added to the tire you need to make sure you're checking the air often as it will leak.

Bluetooth connection has been solid on my iPad Pro.

Any type of drops in power or connection have been solved in firmware updates and Zwift updates.

I have 0 complainers on their trainer.

Update 2022:
Trainer is still going strong! Firmware updates have still been released for this unit. Still working great with Zwift.

Great trainer. I'm not super well versed in trainers, so I can't comment on the "road feel" of this versus the Wahoo unit, etc. But I can say that they're a smaller company and they're very responsive. I had a couple questions while setting this up, and it was easy to get a tech on the phone for help. I've tried that when I had trouble with other cycling bluetooth devices, and the customer service was not as good. The product pairs on the first try every ride, and it works seamlessly with TrainerRoad, Zwift, and CVT.

This is my second smart trainer, I bought the Tacx Vortex and it didn't work, right out of the box and software and apps were difficult to set up. And the training website is not compatible with Apple. I purchased this CycleOps and it was much easier to set up than the Tacx however the Cycleops had a serious construction flaw that made it dangerous to use (one of the leg extensions was not properly soldered to the main body so there was tremendous flex after about 30 minutes of riding). I easily returned that trainer and it was replaced with a perfectly functioning new one. I love this trainer and all it allows you to do with indoor training programs. It's easy to use.

1.0 out of 5 stars Useless Trainer
Reviewed in the United States on February 4, 2017
Verified Purchase
Cycleops has been known for producing generally good quality trainers for years. I wouldn't say high quality as they've had notoriously leaky fluid trainers throughout their history. However at the recommendations of several friends and after researching trainers fairly extensively I decided to go for the Magnus. HUGE mistake.

I'll start with some positives. The frame is adequately built. It essentially does what its intended to though assembling is a bit difficult as putting through the right sided pin to hold the bikes rear axle is challenging and it does not operate smoothly after repeated use.
I have had no significant issues with connectivity or dropped signals via Bluetooth.
Speaking generally smart trainers are definitely the way to go. They definitely make indoor training more enjoyable. So when this particular trainer works as intended it can be a joy.

But here's the main problem. Rear wheel slippage on this model is out of control whenever the grade exceeds 5%. Essentially this renders any hill training and most online training programs that is syncs with useless and therefore makes the trainer useless. How Cycleops could possibly have allowed this to leave the R&D stages without either killing this design or correcting it is mind blowing.

Do yourself a favor and look at the Tacx or Wahoo Kickr or possibly even a Kinetic but steer clear of this joke of a company.

Update: I've now owned this thing for a year. It is no longer responding to commands from the training programs though it indicates that it is connected through Bluetooth. Essentially I have a $600 set of rollers after just over a year. CycleOps "Lifetime Warranty" is a joke...it applies only to the frame not the electronics which this clearly is an electronics problem. So now if I can actually get a hold of anyone at the company as they are based in Wisconsin and they work 8 to 4 with apparently a 5 hour lunch, I get the treat of spending more money to repair this thing. We'll see if they're reputable and make good on they're poorly designed and produced trainer.

I've been using the Magnus for 2 months now and it has worked flawlessly. Easily connects to my iPad for riding on Zwift and other services. One firmware update since I have purchased it after disconnecting halfway through, the second time it loaded with no issues. The tension knob is a very nice feature. The way it has been designed ensures you will have the same exact pressure on your tire (providing you keep the same air pressure of course) every time you install your bike.
