The Quella ELECTRIC Stealth maintains a vintage retro design with the upgraded finishing touches from our Stealth range.   The revolutionary electric motor and battery fit neatly inside the rear hub in a handsome, stainless steel plated body that enables partial re-charging whilst you ride – say goodbye to sweaty rides (if you want to!). You can arrive at work fresh as a daisy or regulate the power to have a great workout.

Our electric hub has 4 power levels –

  1. No assist (manual riding)
  2. Eco mode – Pedal assist with maximum distance (50/60km) from one charge.
  3. Turbo – Maximum pedal assistance up to 25km/h with a maximum power of 250W.
  4. Turbo Custom – Create your own Pedelec power mode! You can change 2 parameters: the amount of BOOST the motor gives you at low speed and the overall amount of ASSISTANCE factor of the motor.

 There is no need for tax, insurance or a licence as this innovative motor is compliant with EAPC law.

Bluetooth technology links the hub to your handlebar remote and your phone so you manage your hub settings through an app. The hub incorporates a regenerative KERS (Kinetic Energy Recuperation System) braking system, similar technology as used in Formula One engines, energy is converted to recharge and power the battery whilst back-pedalling and simultaneously slowing the bicycle down.

Extremely lightweight the Quella e-bike starts at just 13.9kg for our 51 and 54cm frames and 15.2kg for our 58 and 61cm frames.

Our stunning Varsity Oxford is finished in a classic Oxford Blue coloured frame with complementary Quella premium finish kit. Like the two great universities, it competes with the Varsity Cambridge for the top spot.
