  • The VOLT™ has been designed to require minimal maintenance.  Periodically wipe down the VOLT™ with a moist cloth. Wiping moisture away will help maintain quality surfaces.
  • Moving parts like the cassette body can dry out. To maintain a silent ride, occasional application of grease will benefit the performance.
  • Do not use degreasers or petroleum based lubricants and keep corrosive substances clear of the VOLT™.
  • Regularly check the VOLT™ and particularly the mounting system for damage. If you suspect your VOLT™ may be damaged, do not use it and contact your supplier.

FAQs

The Bluetooth protocol FTMS is the most commonly used Bluetooth protocol adopted by indoor trainers. Some manufacturers use their own protocol which causes problems when using 3rd party App’s. All of the major App’s use FTMS for seamless connection.

 

Bluetooth is commonly misunderstood in capabilities. The VOLT™ transmits Speed, Cadence and Power as well as Heart Rate all bundled as one BLE signal. Most devices will only accept one BLE signal except Apple TV. If your device is searching for the VOLT™ via Bluetooth, the device will try to connect to every Bluetooth signal available. (ie. sound system, headphones, 3rd party App’s, speed, cadence and power sensors). If you happen to have any other App’s working in the background or even the JetBlack Cycling App open from a previous session, Bluetooth confusion will happen. When connecting to Bluetooth devices and opening App’s (Zwift included) make sure you have closed any App’s that may cause confusion. For a quick fix, navigate to ‘Settings’ on your phone and switch Bluetooth ‘ON’ and ‘OFF’. This will cut connection to other BLE App’s, if the VOLT™ is active it will easily be recognized.

Ensure your Apple TV is the 4K model or later and you have downloaded and opened your preferred App. Zwift, Rouvy, Fulgaz and RGT are all available now on Apple 4k.

Activate your trainer ensuring all older App’s are closed and BLE is disabled.

 

Unlike smaller devices, Apple TV can handle up to 3 BLE signals. The Apple remote uses one signal leaving two available signals for you to use. We suggest still using the VOLT’s™ bundled BLE signal (Speed, Cadence, Power and Heart Rate) for a simple connection.

All Apple products do not support ANT+. To connect via ANT+ you must purchase an ANT+ Dongle compatible with your device and desired App’s.

Unlike Apple, most Android devices support ANT+. Meaning no Dongle is required.

ANT+ supported devices can be found here.

Ensure you PC supports either Bluetooth or ANT+. If choosing ANT+, for best connection ensure the Dongle and VOLT™ trainer are in close proximity and have clear line of sight.

If using an extension cable to support the ANT+ Dongle, ensure stable connection between both. This is not ideal as in some cases signal transmission can be impaired.

Definition of ERG- a unit of work or energy, equal to the work done by a force of one dyne when its point of application moves one centimeter in the direction of action of the force.

The VOLT™ Erg method uses a complex model of the VOLT Smart’s power to calculate what resistance would be required to achieve the target power at the current speed and temperature. The resistance is adjusted to account for changes in speed and temperature to ensure the target power is met.

Erg mode is great for sustained efforts and for best results base your intervals around cadence. Set your target power then maintain your target cadence. Sudden cadence increases and decreases will affect the stability of your trainer’s target power.  The VOLT™ trainer will stop searching ERG (targeted power) at 10kph and restart once the rider goes above 15kph.  Most App’s will have a default built into their ERG. We suggest for a great ERG experience for the unfamiliar, use the small chain ring until becoming confident in your technique.

Suggested technique.

When the interval starts, maintain the same cadence until targeted wattage is achieved. You can adjust cadence from here in small increments. Sudden changes will affect the performance of your ERG workout.

 The VOLT™ uses an electromagnetic system to apply resistance. An electric current level is calculated and applied to an impermanent magnet to generate an electromagnetic field. The electromagnetic field exerts an electromagnetic force on the magnet, which provides resistance to the VOLT™ trainer in turn applying resistance to the user. This electromagnetic magnet system provides resistance over the conventional gravitational force used in free weights.  Other forms of resistance systems used in bike trainers are wind, magnet (non-electrical) and fluid.

The JetBlack VOLT™ maintains a 2.5% accuracy reading. This has been achieved through many hours of testing and firmware design. A calibrated jig attaches directly to the VOLT™ trainer to establish the base power profile. A series of tests are performed using Assomai Pedals, Quark Cranks and SRM Cranks (best in class for testing). The data gathered and analyzed enables JetBlack to achieve the targeted 2.5% accuracy. Our awesome team of electrical engineers design the firmware from this raw data to the smooth, accurate and rider responsive VOLT™ trainer we have now.

We decided early in the piece not to use a strain gauge on the VOLT™. With the huge range of results gathered from testing many power meters and the added problems associated with shipping and handling, air flow, humidity, mechanical design it was decided to use firmware to predict the power output (watts) on the VOLT™.

Through the design process, we noted how different each device was and how it reacted in different scenarios. We have found no two devices recorded the exact same readings. If you were to compare your 3rd party power device with the VOLT™ trainer the potential differences maybe influenced by the following factors:

 

  • Data transmission Speed/Rate (signals sent at different intervals)
  • Equipment tolerances
  • Rider technique
  • Wireless interference
  • Temperature (airflow, heat within the unit compared to external device)
  • Humidity
  • Sensor location
  • Calibration process
  • Battery life

 

The VOLT™ is rated to a simulation gradient equivalent to 16%. If you unit becomes very hot with excessive use this gradient may be compromised to support the functionality of the trainer.

Max Power of the VOLT™

  • 15kph = 350 watts (hill climb)
  • 40kph = 1250 watts (high intensity short intervals)
  • 60kph = 2000 watts (sprinting)

This is a measurement of the capabilities of the VOLT™.

The VOLT™ power accuracy has been designed for best performance with a Spin Down Calibration. To get the most accurate readings we suggest using the JetBlack App to complete a Spin Down Calibration. (You will find this in the ‘Settings’ page) DO NOT USE THIRD PARTY SPIN DOWN CALIBRATIONS; this will damage your VOLT™.

Heat plays a big part in the accuracy of your power readings, the warmer the trainer before spin down, the more accurate your readings will be.

The JetBlack VOLT™ uses industry standard protocols (ANT+ FE-c and Bluetooth FTMS) allowing us to connect to most Third Party App’s.

App’s include:

The VOLT™ comes assembled with a 10/11 speed Shimano/Sram cassette and compatible body. The VOLT™ is Sram XD-R 12 Speed compatible. Please see your supplier to fit other types.
