Introducing the latest i9 innovation – the Hydra Frequency Adjust Ratchet Technology. Whether looking to ride in silence or want to make your presence known on the trail, the all-new adjustable Hydra drive mechanism is Bluetooth connected for on-demand tuning.
Ranging from “silent but deadly” .5 db, to “blackout inducing” 150 db, the latest Hydra technology is tuneable for any riding condition. Just be careful, cranking the Frequency Adjust Ratchet to 11 is not suitable for all riders.
