Tacx Flux 2 Electromagnetic Direct Drive Bicycle Trainer
8714895058610
A stable, heavy-flywheel direct-drive trainer for riders who want reliable sprint stability and realistic climbing simulation, without a fussy setup.
Overview
Flux 2 is Tacx's redesigned direct-drive trainer, built around a stronger resistance unit and a heavier flywheel than its predecessor to improve both ride feel and data accuracy. It's a genuine plug-and-play trainer — remove the rear wheel, mount the bike, and it's ready to ride.
What's actually equipped: an electromagnetic brake working with 8 permanent ferrite magnets and 8 electromagnets drives the resistance unit, paired with a 7.6kg flywheel that simulates a much heavier effective mass at the flywheel for a genuinely realistic pedalling feel. The well-balanced, large-footprint design keeps it stable through explosive sprints up to 2,000W, and spin-down calibration keeps the power readings accurate over time.
It's built for riders who want a dependable, stable trainer for regular structured sessions or Zwift racing — somewhere the sprint stability and climbing simulation actually get used, without needing the outright ceiling of a flagship trainer.
Why You'll Like It
Stable Through Hard Sprints
The large-footprint, well-balanced design keeps the trainer planted even during explosive efforts up to 2,000W.
Realistic Climbing Feel
Gradient simulation up to 16% is backed by a heavier flywheel and stronger resistance unit than the original Flux, so climbs feel genuinely resistant rather than artificially light.
Genuine Plug-and-Play Setup
Remove the rear wheel, mount the bike, and you're riding — no complicated calibration ritual before every session.
Wide Bike Compatibility
Axle compatibility covers 130mm, 135mm, 142mm, and 148mm hub widths, so most road, gravel, and mountain bikes fit with the right adapter.
Who Is It For?
Riders in India who want a stable, dependable direct-drive trainer for regular structured training or Zwift racing, without paying for a flagship trainer's outright power ceiling. It suits anyone who values a trainer that stays planted during hard efforts over one with maximum resistance headroom.
It's also a solid choice for a household training space where stability matters — the large footprint and heavy flywheel keep it settled even during sprint intervals.
Good to Know
A one-month free subscription to Tacx Premium is included, giving you a head start on structured training content.
An LED indicator confirms your connection status at a glance, useful for quickly checking a Bluetooth or ANT+ pairing before you start.
The trainer requires mains power to operate — it can't run resistance control without being plugged in.
