Top 6 Best Smart Turbo Trainer

Top 1: Tacx NEO 2 Smart Indoor Trainer

Tacx Neo 2 Smart rollers are the best smart turbo trainer on the market that is solid and practical. Thanks to the weight of the flywheel, it guarantees realistic pedaling downhill. It is not exactly perfect but pleasant when used with Zwift.

The Downhill function is available. When you stop pedaling, the roller does not stop immediately but guarantees the feeling of continuing to have inertia. However, this feature only works if it connects the tool to the mains.

The device has a maximum peak resistance of 2200W, making it perfect for sprinting jobs too. It also has a negative consequence that the roller is challenging to move given by the excessive weight. Through the ANT+ protocol, you can record data on Garmin, and manage the roller itself.

The roller is decidedly quieter than non-direct drive ones. Therefore, you can also use it in an apartment. The noise you hear is the bicycle transmission since the cooling fan is not noisy.

Top 2: CycleOps H3 Direct Drive Indoor Bike Trainer

The CycleOps H3 model is a scaled-down version of the flagship model. The Core frame is less robust, the flywheel is slightly smaller and does not include a sprocket set, but the price is much lower. The CycleOps H3 trainer is a silent and reliable, smart trainer with a high-power calculation accuracy. The roller has a maximum power of 1800W and simulates a slope of 16%.

This roller may sound simple, but you need to push hard on your bike because the rollers require you to keep pedaling. It means it is even harder to stop to breathe. They ensure a stable and non-vibrant ride that is ideal for those with limited home space.

Thanks to the ANT+ or Bluetooth connection, you can use the trainer with all the most popular applications, such as Zwift. Also, we have some unique accessories, such as the Climb slope simulator and the Headwind fan.

It offers a fast response from electronics and flywheel to transmit even the smallest changes in resistance.

The manufacturer also provides speed, cadence, and power data on smartphones, tablets, and computers. The maximum resistance is 1500 Watts of power within 10 seconds (via electromagnets) and a maximum slope of 10%. Tacx Flux comes with a universal EDCO Multisys body that fits all Shimano and SRAM cassettes. Like most direct drive rollers, Flux produces minimal noise, even during the most intense efforts.

For people who do not want to spend too much, the Tacx Flux smart trainers are an interesting solution. These are magnetic rollers that allow you to control the resistance through a small lever to be mounted on the handlebar, connected to the tool by a cable.

The level of resistance it offers is good, but not great. Also, when you push hard, the rear curtain wheel slips. The item includes the rollers, the hubs for the wheel that connects to the rollers, and the change knob to be fixed to the handlebar.

The trainer is supported by Zwift and features the FE-C system, Fitness Equipment Control. It allows the setting of the resistance level to simulate a certain path, such as a climb.

It means that a roller with this characteristic allows synchronizing the slope variations established by the program with the resistance of the braking unit.

  • Reasonable price
  • FE-C system and Fitness Equipment Control
  • Zwift support

Who Should Buy Smart Turbo Trainer

Anyone who does it like a true professional or even for an irresistible passion knows well the reasons you cannot train on the street during the winter months. Rain, snow, frost, and reduced visibility make outdoor practice dangerous, even for the most extreme mountain bikers.

Best Smart Turbo Trainer FAQs

How do bike trainers work?

The principle of the rollers is very simple. They comprise a small stand, to which it attaches the rear wheel of the bike.

The wheel remains slightly raised from the ground and the surface of the tire rests on a roller coated in rubbery and elastic material. When pedaling, the rear wheel turns and by friction it makes the roller rotate.

Inside the roller, it connects the roller to a flywheel. It is a heavy disc that spins and guarantees the inertia necessary to make pedaling smooth. There is also a brake system that reproduces the friction of the road and the air.

What is a virtual reality with bike trainers?

The rollers come with a resistance change system, comprising a knob control that is fixed on the bike handlebar. Or in most advanced systems, the resistance is controlled directly by a computer or tablet that can also reproduce training programs.

Is the training duration of a smart trainer useful?

Usually, shorter sessions are performed on the rollers than on the road. They allow you to practice more targeted exercises. The average running time is between an hour and an hour and a half. The metabolic effort is greater as the exercises take place at a constant temperature and there is no possibility of adequate cooling. There is also the aim of psychological difficulty of sustaining training for longer times.
