Powerful 500W Motor

  • Purpose built for top speed 500W 48V electric motor. Feel the surge of quiet, consistent power distribution at higher speeds – vibration-free.
  • Geared for performance – we paired all that power with an industry-leading 12mosfet 25A controller to deliver unmatched torque and speed.
  • Watch out for other riders as you zip pass them.


Whisper Smooth Torque Sensing Pedal Assist

  • Because an electric bike is only as good as it’s power distribution.
  • Werk’s incredibly smooth torque sensor knows how hard you’re pedalling down to the microsecond and matches it with proportionate power.
  • Gone are the days of simple cadence sensors!
  • 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.

Tires with Style & Toughness

Versatile street style tread offers a smooth compliant ride with positive grip characteristics.

Standard Rubber Compound combines the best attributes of low rolling resistance, extreme durability and tread longevity into one universal package that benefits riders of all disciplines.

Sharing the same versatile tread pattern as the Kwick Nine and the Kranium, the Kwick Seven.5 takes advantage of the intermediate sized wheel on 27.5″ (650B) bicycles so you can ride the streets as efficiently as you do off road.

KENDA KWICK 27.5″ X 2.6″ SEVEN-5 features K-Shield protection – a layer of aramid and ceramic particles inside the tire under the tread area for puncture resistance and a Reflective Trim for better urban visibility, the Kwick Seven.5 is ready for your urban adventures.
