The trainer operates with or without external power connection. Start pedaling and the magnets generate sufficient electricity to power the electronics, connectivity, and LED status lights. This unplugged mode supports resistance up to 2200 watts and works for warm-ups in race parking lots or locations without convenient outlet access. Connect power to activate descent simulation where the trainer actively drives the flywheel to replicate downhill acceleration when you stop pedaling on virtual descents.

Gradient simulation handles climbs up to 25% grade, covering the steepest pitches programmed into current virtual training environments. The redesigned motor delivers stronger low-speed torque compared to earlier NEO models, improving resistance feel during standing climbs and sprint efforts. Instantaneous response to ERG mode targets and slope changes eliminates the lag common in belt-driven trainers where mechanical inertia delays resistance adjustments.

Connectivity spans ANT+ FE-C and Bluetooth Smart FTMS protocols for simultaneous pairing with multiple devices. Run Zwift on a tablet while broadcasting power and cadence to a Garmin Edge computer for concurrent data recording without choosing between platforms. The trainer communicates with smartphones, tablets, bike computers, and desktop training software without requiring ANT+ dongles for Bluetooth connections.

Axle compatibility covers 130mm and 135mm quick-release standards plus 142mm and 148mm thru-axle dimensions without adapter swapping. The cassette body accepts Shimano and SRAM 8-speed through 11-speed cassettes out of the box. Campagnolo users need a separate freehub body sold as an accessory. The redesigned axle system improves bike mounting compared to earlier NEO generations and accommodates wider hub spacing without clearance concerns.

Three folding support legs collapse for storage and transport though the 21.5kg weight makes frequent moves challenging without handles. Rubber feet protect flooring and the triangular footprint provides stable platform during high-intensity intervals and sprint efforts. The flat black casing presents clean lines compared to traditional trainer aesthetics and integrated LED lights illuminate the floor during operation while indicating power and connectivity status through color changes.

Noise output remains minimal because electromagnetic resistance generates no belt friction or flywheel wind. Drivetrain sounds from chain and cassette become the primary noise source during operation. The quieter operation comes from redesigned magnets that reduce internal air displacement and vibration transfer to the floor at low cadences. This makes the NEO 2T viable for apartment training and early morning sessions without disturbing household members.
