The Tacx NEO Smart offers the best in power & intelligence & is the quietest indoor trainer currently available on the market. The lack of any physical transmissions means this is the first true direct drive. Road feel is simulated in a highly realistic manner, there is no loss of power. The powerful motor is able to apply resistance up to 2200 Watt & simulate slopes realistically up to 25%. It also speeds up during descents. This ensures the most realistic cycling experience, also during climbs. The lack of any physical transmission, & in turn any parts that could rattle or rub against each other, ensures this trainer is extremely quiet. In addition, this trainer requires no calibration & suffers no wear & tear. Just like other Smart trainers, the NEO communicates using ANT+ & Bluetooth Smart, allowing it to be connected quickly & easily with Tacx apps. Performance data can be viewed on several devices simultaneously, including your smartphone, bike computer & sports watch. Furthermore, the Tacx NEO features Plug in/ Plug out technology & can therefore be used with & without a plug. When the plug is not in use, the trainer will act as a wireless motor brake. This means the trainer will be not be able to speed up during descents. The NEO represents the ultimate in ease of use. Direct Drive The operating principle represents direct drive technology in its purest form. Any physical transmissions such as belts, rollers or wheels have been omitted in order to ensure optimum power efficiency, from the pedal to the motor. Thanks to an uninterrupted power flow, you wont lose a single bit of output or power. A virtual flywheel dynamically controls the brake force. This means that the resistance is calculated & adjusted continually to simulate natural road resistance. Whereas other trainers use a flywheel to pass the dead centre, the NEO uses calculations to predict the movements of the bike & simulate the action of a flywheel. The inclusion of FAST technology means the NEO carries out a 1000 calculations per second to predict the riders movement. The virtual flywheel can generate a variable inertia effect, allowing it to simulate the bike movements of all cyclists up to a specific bodyweight (125kg max.) in a highly accurate manner. When calculating the brake resistance required, all physical formulas a cyclist encounters on the road are applied to create a situation that is as realistic as possible. Air & rolling resistance, gradient percentage, weight, air pressure, wind speed, temperature, altitude, inertia & brake properties are all taken into account & calculated hundreds of times per second to achieve a realistic feel.
