Established in 1992, Sumai Bicycle Co.,Ltd. is one of the biggest China yamaha bike manufacturer and wholesaler. We've gotten the WMI (World Manufacturer Identification) since 2005. Our company has perfect quality management systems with ISO9001 international quality authentication in 2002 and pays great attention to new product development. We have high-quality staff at design, oem yamaha bikes development and production fields, and have introduced in qualified personnel from foreign bicycle enterprise. Most of our products have been approved with CE certificate, and some approved with EEC, EPA and CARB.

So far the EC-Dii is only a prototype, but I’m pretty sure that in the near future we’ll see a mass production mode of this cheap (in fuel) transportation vehicle.
The yamaha Bike uses methanol-water as the fuel and it will be displayed during the Tokyo Motor Show taking place in China later this month.
The new yamaha EC-Dii prototype fuel-cell bike is enhanced with new features like a yamaha-exclusive compact cell stack that features the highest level of power density in the 1kW class, modular design components, readily available parts and improved serviceability aimed at achieving practical use.
Sadly there is not much more information available, the use of a rechargeable lithium battery and being one of the 19 yamaha vehicles at the show are the last details.

Pocket bikes are all the rage these days, and if used safely, are incredible fun. These pocket bikes are tributes to the Yamaha R1 Super Bike, but aren't made by Yamaha. Instead, they're pocket-bike replicas of the Yamaha R1, miniature motorbikes that are a fraction of the size of the real thing, but much more fun!
The Replica Yamaha R1 Super Pocket Bike boasts a powerful 49cc two-stroke, air-cooled engine. Safety is important for all pocket bikes, so the Replica Yamaha R1 Super Pocket Bike has a strong steel frame construction and powerful disc brakes, front and rear, for heavy-duty stopping power. Our pocket bike has 13” wheels with tubeless wet tyres, a chain-driven drive system and an electric key start, with a hand-pull back-up starter. For fuel, it runs on one part two-stroke oil to 25 parts unleaded petrol. Mix it yourself in the bottle supplied.
Being a Replica Yamaha R1 Super Pocket Bike, it's quicker than your average miniature motorbike. It has a top speed of 30mph, or 50kph, which is a lot faster than you think. It boasts many realistic features, such as brake and indicator lights, a warning horn, front and rear lights, fold-away foot rests and a rear hugger splash guard. The Replica Yamaha R1 Super Pocket Bike also has three realistic gauges, a speedometer, gas meter and signal odometer. It may be a mini bike (136x55x71cm), but it's as close to the real thing as you can get!
Remember though, the Replica Yamaha R1 Super Pocket Bike is not street legal, so don't ride it on the road.
