Tacx Flux Smart Trainer

The maintenance-free Flux Smart is a compact and realistic interactive direct drive trainer. The swift response of the Smart electronics and the 7kg flywheel transmit the slightest fluctuations in resistance directly and accurately to your legs.

The trainer combines direct drive technology with an electro brake in order to offer an accessible smart and interactive direct drive. The Flux also has a powerful 1500w motor and a maximum slope range of 10%.

ANT+ & Bluetooth Compatible

The Flux Smart is connected wirelessly to smartphones and tablets and knows the ANT+ FE-C protocol, enabling you to train with Tacx apps as well as third-party apps like Zwift and TrainerRoad. You can also train stand-alone, so if you do not want to connect the trainer, it will simulate a flat road. LED lights on the side of the trainer show when it's connected to the mains and to a device over ANT+ or Bluetooth. With the Tacx utility app, you can always benefit from the latest firmware for the Tacx trainer and check the connection with other devices. When an update is available, you receive a notification and you can decide whether you want to update your trainer.

Quiet Direct Drive Trainer

The set up of the Flux enables an easy, automatic calibration process to ensure a high <5% accuracy in wattage drift when cross-referenced with an independent power meter. This means you can rely on the power data you see before you and take confidence from your indoor sessions, knowing your indoor power is relative to what you will produce on the road. The inner parts of the trainer are carefully selected to minimise sound levels. It is so easy to get going with the trainer due to its simple plug and play set up, simply remove your bike’s rear wheel and place it directly on the trainer, step on and start training.

The Flux is stable and robust and has been designed to enable you to really push your limits, especially when standing on the pedals.

The Flux is a sound stationary trainer that offers buyers a suite of thoughtful features, including a clever freehub body along with a fair amount of grunt in terms of resistance and slope choices.
