For some time, Yamaha has been perfecting designs for vehicles that use electric power as a viable, low-emission alternative to petrol.
The EC-03 is the result of that continuous effort. This pure electric commuter draws on knowledge and technologies developed over three decades. Slim and compact enough to wheel inside, but punchy enough to cut through rush-hour traffic - the EC-03 defines a new kind of convenient, low-impact urban travel.
Designed for users of all experience levels - including those who've not previously ridden a scooter or motorcycle - the EC-03 also features silent operation and incredibly low running costs.
Convenient and economical
Thanks to a built-in charger unit, the EC-03 charges from any common wall socket using a single cable. It's simplicity itself - and with a full charge costing a fraction of a tank of petrol, the EC-03 is exceptionally economical to run.
Quiet and green
As a pure electric vehicle, the EC-03 is kinder to the environment, with zero emissions resulting from usage. Electric power also means no noise during your journeys. A special YIPU power unit combines efficiency with a slim, light design; and for an extra boost, you can switch from Standard to Power mode at the touch of a button.
Easy controls
Controlling the EC-03 is effortless, thanks to an electronic throttle built into the handlebar grip. This works with the high-spec motor controller for lively, smooth performance. A stylish meter panel with digital LCD display keeps you alert to speed and battery levels, and electronic sound functions alert you to low battery or indicator use.
Slim and light
With a specially-designed aluminum alloy pipe frame, the EC-03 weighs just 56kg - making it easy to handle on the road, to wheel indoors for charging or storage, or to load into a caravan or car if you're heading away for the weekend.
Feel good
The seating on the EC-03 is designed to make every ride a pleasure. Seat height, seat hip position, footrest and handlebar position are calibrated for an upright riding position that looks and feels good, with easy leg reach to the ground.
Suspension for added comfort
The EC-03 features a rear suspension system with large-diameter spring coils, which lets riders take bumps and potholes in their stride.
See and be seen
A stylish mutli-reflector headlight ensures excellent illumination during dark conditions.
Handy extras
The EC-03 includes three handy features for riders: a grab handle for easy parking, a luggage hook at the front of the seat for fastening baggage during motion, and a wire helmet holder underneath the seat - ideal for securing your headgear when the scooter is parked.
