WHISPER SMOOTH TORQUE SENSING PEDAL ASSIST

Because an electric bike is only as good as it’s power distribution.

  • Quad’s incredibly smooth torque sensor knows how hard you’re pedaling down to the microsecond and matches it with proportionate power.
  • Custom drop out design delivers whisper smooth torque sensor sensation at any assist level. In fact, you’ll swear it’s as so smooth as a mid-drive motor.
  • Gone are the days of simple cadence sensors!

REDESIGNED COCKPIT

Now with an extra-large colour LCD display to show all vital information and provide added security.

TIRES WITH STYLE & TOUGHNESS

Impressive aggressive trail capabilities, thanks to its stock Maxxis Rekon+ Skinwall 27.5" x 2.8" 35PSI plus size tires with 3C and EXO casing.

That larger contact patch means more grip, less feedback from small bumps and greater comfort.

Other eMTBs are simply not this sure-footed.
