Electric Single Speed Bike – Commuter eBike – Pedal Assisted Fixie Bicycle – Silver / Black – 58cm ( 5′ 11″ to 6′ 1″ ) – Quella Bicycles

New for Winter 2019, the Quella ELECTRIC Varsity range of fixie bikes.

The same vintage retro look but with an inconspicuous revolutionary electric motor pedal-assist drive system that re-charges whilst you ride.

The Quella electric hub is at the very forefront of technology offering the simplest and cleanest design pedal assist cycle system. It is ideal for those folk on the move, particularly those commuting who may not usually consider the cycle to work for several reasons, from distance to landing appearance. The Quella electric provides the opportunity to ride single speed but puts you in control of how much effort you exert – say goodbye to sweaty rides (if you want to!). Although the e-Quella is pedal assisted it’s still an exercise, offering low cost, energy efficient, and emission-free travel, with all the physical and mental health benefits whilst arriving in similar appearance as driving or taking public transport.

The best way to describe the experience is as though every ride is with a subtle and supportive tailwind!
The technology is revolutionary as both the motor and battery fits inside the rear hub in a stainless steel plated body. It contains a powerful brushless electric motor that complies with the ped-elec standard so no need for tax, insurance or a licence. Bluetooth technology let’s you link the hub to your mobile phone so you manage your hub settings through an app.
The hub includes the regenerative KERS system, similar technology as used in Formula One engines in which energy can be converted to recharge and power the battery whilst in motion. The converted energy may not be sufficient in keeping your hub from a plug socket all year however it will certainly reduce the need to power up the battery as a conventional bicycle electric motor, whilst doing your bit to help the environment.

The hub system is variable on our Varsity range only built around an upgraded 4130 frame and fork. The Varsity model features sealed headset, bottom bracket and wheel hub bearings, an intricate vintage aluminium 44T crank, and a full Quella Premium finishing kit for improved comfort and performance.

The eye-catching Varsity Imperial is named after the university nestled in the heart of London. This single speed bike with exclusive chrome paint job draws inspiration from the high-rise skyscrapers dominating our capital’s skyline.
