1. Powerful 500w Motor

  • With a torque sensor and throttle on demand, the Rook is great for those that could benefit from an extra boost to make it up the hill.
  • Geared for performance - we paired all that power with an industry-leading 12mosfet 25A controller, so Rook delivers unmatched torque and speed.
  • Watch out for other riders as you zip pass them.

2. Long-Range Battery

  • Rook's high capacity 48V 14Ah Samsung lithium-ion battery provides maximum range.

  • Rook's incredibly smooth torque sensor knows how hard you’re pedalling 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 smooth as a mid-drive motor. Gone are the days of simple cadence sensors!

 4. Redesigned Cockpit
