Intermot Exhibition, Cologne, Germany, 05 October 2010: Yamaha today introduces a new way for urbanites to commute. The EC-03 is a vehicle with a difference: a pure electric bike that’s slim, fun, and totally emissions-free.
Designed for busy city-dwellers who want to switch to independent electric transport, the EC-03 provides a fast, convenient way to get round town. It’s slim and compact enough to take into the office, can be charged from any standard wall socket, and boasts a stylish design that guarantees to turn heads on any street.
A timely response to the increasing need for urban transport with a low environmental impact, the EC-03 offers a fun, approachable way to travel – even for those who’ve never used a scooter or motorcycle before. With virtually no operating costs, it’s economical to run, and combines silent, clean operation with surprisingly nippy performance.
For a more versatile ride, the EC-03 features a choice of two motor modes. When riders need to boost their speed, they can switch from Standard mode to a special Power mode at the touch of a button – it’s ideal for overtaking or any moment when you can’t wait around.
Plus, thanks to its lightweight build and slim proportions, the EC-03 can easily be carried in a car or caravan if you’re heading away on vacation or for a weekend break.
The EC-03 will be available to buy in Yamaha dealers throughout Europe from the beginning of 2011.
Easy to charge
With the EC-03, riders can say goodbye to the hassle, expense and environmental impact of petrol power.
Thanks to a handy built-in charger unit, the EC-03 can be connected straight to any standard mains supply, using an electric cable. With a full charge taking around seven hours, the EC-03 can easily be charged to full power during a working day or overnight.
A full charge offers sufficient power for a journey of approximately 46km at 30km/h on a flat road. In Standard mode it achieves a running distance per charge of 30Km while in Power mode it reaches 20Km.
Super-slim power unit
The EC-03 owes its slim build to Yamaha’s specially-designed YIPU (Yamaha Integrated Power Unit). This innovative unit uses a direct-drive type in-hub motor, which minimises power-transmission loss, and a mini-computer control to calculate optimum output at all times.
In combination with the EC-03’s optimised gear settings and specially designed tyres, the YIPU helps to deliver a silky-smooth, near-silent ride – with none of the heat, vibrations, noise or exhaust gas you’d expect from a petrol-powered vehicle.
The YIPU has also been calibrated for maximum torque at low speeds, allowing riders to power away from the lights and leave cyclists standing.
Easy controls and instruments
Controlling the EC-03 is simplicity itself, thanks to an electronic throttle built into the handlebar grip. In combination with the high-spec motor controller, this ensures lively, smooth running performance.
To ensure riders stay informed of key vehicle information, the EC-03 includes an instrument panel with digital LCD display with speedometer and battery charge gauge.
As a safety precaution, electronic sound functions are included for the indicators and battery-low signal. Riders can also verify that the machine is in perfect running order by pressing a dedicated switch on the panel when starting the EC-03.
An effortless ride
At just 56kg, the EC-03 is easy to handle and manipulate when you’re on the road - and equally easy to wheel indoors for storage or charging. This lightweight construction is the result of a newly designed aluminium-alloy pipe frame, which is around 30% lighter than a 50cc gasoline engine scooter. Simply-designed exterior components enhance the feeling of lightness.
Riders will also notice that the EC-03 offers exceptional straight-line running ability. This is due to the careful calibration of all individual machine parts for an optimised weight balance.
Sit properly, feel good
The seating on the EC-03 is designed to make every ride a pleasure, with a set-up that combines compactness and ergonomics. Seat height, seat hip position, footrest and handlebar position have all been calibrated to create a straight-backed riding position that looks and feels good. The shape of the seat is optimised for easy leg reach to the ground.
Comfort is further assured by new rear suspension with large-diameter spring coils, which lets riders take bumps and potholes in their stride.
See and be seen
The EC-03 is equipped with a stylish, multi-reflector headlight (automatic lighting type) – ensuring excellent illumination, especially during night riding.
The EC-03 features a unique mutual-communication type controller YMCS (Yamaha Mutual Communication System). This allows battery, controller, charger and meter systems to operate constantly, exchanging data – for automatic control of key functions in all conditions.
The result is easier operation for the user and smooth running performance, as well as several important security features. Users can lock the EC-03 by key code on the meter panel, making it difficult to steal. The EC-03 will also not function during charging, or when the wheel is lifted off the ground.
Crucially, if an error is detected in the vehicle system during start-up, the EC-03 can intelligently decide to stay in error mode (and cannot be ridden until the problem is fixed), or - for smaller errors - allows riding but with limitations (for example, no battery level indication).

• User-friendly design
