Fluid2 Trainer Smart Equipped

Saris takes its top-selling trainer in the USA and adds a dual-band ANT+ and Bluetooth speed sensor so you can reap the benefits of virtual training via apps like Zwift and Rouvy. The fluid resistance unit is quiet (64-68 decibels at 20mph), and offers a progressive power curve that increases the resistance as you shift gears and pedal harder—just like if you were on the road.


  • Reliable trainer that's ready for virtual and non-virtual rides

  • Included speed sensor lets you pair with training apps like Zwift

Easy Set Up!

Was gifted this for Christmas this year and had it set up the next afternoon. Took less than an hour to get it set up with bike attached and I am not someone who typically does my own work on my bike so removing the rear wheel was a new experience. Clear instructions, easy to follow. The most confusing part was trying to understand how to affix the included speed/cadence sensor to the rear wheel hub. The instructions for this are small, and images were not helpful but once I figured out the steps, it was easy. Was up and riding a couple training rides on Rouvy, using the included free month trial code, by mid afternoon. First impression is that I will be happily using this daily at least.

The trainer is great, the speed sensor is HORRIBLE

Bought this a year ago and have used it over the winter months. The trainer is great, provides constant and even resistance. I would HIGHLY recommend a trainer specific tire, as anything with a tread will be noisy. The included Saris Speed Sensor is awful and I ended up purchasing a different one to provide the feedback I wanted.

Winter training

Very happy with my purchase, this trainer is quieter than expected. It’s easy to set-up, installing your bicycle on the trainer is simple and Saris even supplies a metal skewer. I should of made my purchase sooner! I wish it would come with 2 sensor strait in the box?

Buying was a good decision.

After quite a bit of research into the somewhat confusing world of indoor trainer reviews I purchased this trainer with the speed sensor and have been very pleased with my decision. Combined with the Rouvy app I am able to get a great workout virtually biking around the world.

I like it.

I like it. Took weeks to get the attention of the support team to get the sensor working. But the trainer it self is good. I can watch TV at a reasonable volume while riding, it's a good workout.

Solid and reliable trainer

I have owned a Fluid 2 for 6 years, it has never skipped a beat. The speed sensor let's me log mileage and speed via my Wahoo Element for my indoor workouts. Most important is the lack of power limitations of this trainer. Unlike many of the smart trainers that freak out after a 5 minute block at 400W+ , this unit maintains it's resistance no matter what, even if you spoke beyond 1000W during your sprints.

So easy to set up

I've had my trainer for about a month and I use it 3 or 4 times a week and I just love it. It was super easy to set up... the hardest part was getting my bike down the basement stairs. Easy to use, connected easily with the apps that are out there.

Fluid trainer

For a basic trainer, its awesome. I have used it for about a month and its fun, quite and exactly what I was looking for . Saying that the sensor needs to better. It does not work as cadence but great as speed.

More of a dumb trainer

Speed/cadence sensor is trash, disconnects more then my dial up in the 90's
