Today, China is the world’s leading producer of e-bikes. According to the data of the China Bicycle Association, a government-chartered industry group, in 2004 China’s manufacturers sold 7.5 million e-bikes nationwide, which was almost twice the year 2003 sales; domestic sales reached 10 million in 2005, and 16 to 18 million in 2006.
The part that confuses me is the “saddle”. Recumbent trikes do not have the typical bicycle saddle seat. They have a nice comfy fully supportive seat. Some are like bucket seats. So then I’m thinking, would it be a moped under WA law?
What is it? Back to the definitions, since it is not an electric bike, it CAN be a motor driven cycle. So it is a Moped, and a moped IS a motor vehicle. If I look up the requirements for mopeds in other statutes, I may find my homemade moped will not be legal without lights, turn signals, dot approved tires, valid drivers license needed, etc etc etc. If that is so I’m screwed! ARRRGHHH!

Last year we heard about the Draisine 200.0, a one-off wooden electric balance bike for adults. Well, if you wished that you could buy something like it, now is your chance. The Big Buddy Bike has a tempered wooden frame, it’s adult-sized, and it’s an electric balance bike – of a sort.
Nicolas Zart Nicolas was born and raised in the world of classic cars of the 1920s. It wasn’t until he drove an AC Propulsion eBox and finally a Tesla Roadster that the light went on. Eager to spread the news of that full torque, he started writing in 2007 for various CleanTech outlets. Since then, his passion led to cover renewable energy, test drives, podcasts, shoot pictures, and film for various international outlets both in print and online. Nicolas offers an in-depth look at the e-mobility world through interviews and the many contacts he has forged in those industries. Today he focuses most of his writing effort on CleanTechnica, a global online outlet that covers the world of electric vehicles and renewable energy. His favorite tagline is: “There are more solutions than obstacles.”

The Japanese giant, which manufactures everything from motorcycles and musical instruments to personal water scooters and motorboats, will begin selling Yamaha Power Assist Bicycles through U.S. dealers in 2018.
And let’s not forget the economic advantages of owning an e-bike. The annual cost of running a new family car is, on average, about $9,000 per year. Running an electric bike costs around $400 per year. And while filling a gas tank costs around $30, recharging an electric bike battery costs only about 50 cents. A tank of gas may get you further, but not 60 times further!

There are two distinct types of controllers designed to match either a brushed motor or brushless motor. Brushless motors are becoming more common as the cost of controllers continues to decrease. (See the page on DC motors which covers the differences between these two types.)
Lower the voltage. Depending on the battery, the first block or two of riding might do the trick. If your battery drops voltage fast, you might be a lot slower than 20-MPH for 98% of your ride. I’d call that close enough if that is the case. Or maybe I can just charge my battery to a lower voltage. Maybe if I charge it to 40 volts instead of the normal 42V-44V, I won’t be quite so fast. That could work if my battery still gets me going 23-MPH for too long to fudge it.
Unlike drivers of electric cars who are plagued by “range anxiety,” electric bike owners don’t have to worry about running out of electricity: They can travel under their own power, assuming they’ve got the energy to pedal a bike that weighs 45 to 60 pounds. Batteries typically deliver 20 to 40 miles of assisted riding, and they can be recharged in a few hours in ordinary power outlets.
Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas. It seemed almost every bike vendor at the show has at least one fat bike model in their booth this year. On top of the fats were the electric bikes. And I think it goes without saying that nobody wants to actually pedal a fat…

We Can Build It. Built by hand in Pennsylvania, mostly by Harry and Alec. Custom Wheelbuilding Some people don’t know that we build every one of our wheels here by hand in Pennsylvania. This lets us control each step of the process, ensuring that the spokes are uniform, straight, and undamaged, allowing us to apply spoke-prep to the spokes, oil to the nipple seats, and inspect the rims before…
By 2007 e-bikes were thought to make up 10 to 20 percent of all two-wheeled vehicles on the streets of many major Chinese cities. A typical unit requires 8 hours to charge the battery, which provides the range of 25 to 30 miles (40 to 48 km), at the speed of around 20 km/h.
They’re Entering the Public Domain: There’s a good change that e-bikes are coming soon to a city bikeshare program near you, especially if you live in California. The Golden State’s goal to get 1.5 million zero-emissions vehicles on the road by 2025 has opened up the funding pot, inviting electric bike share providers to apply.
Four prototype bikes, shown at the annual Interbike cycling convention that opened today in Las Vegas, will be offered to retailers. The production models will wear the traditional Yamaha fork emblem, which harkens back to the company’s roots in musical instruments.

“[the] electric motor must have a power output of no more than one thousand watts, be incapable of propelling the device at a speed of more than twenty miles per hour on level ground, and be incapable of further increasing the speed of the device when human power alone is used to propel the device beyond twenty miles per hour.”
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.

Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.
An Electric Boost for Bicyclists by J. David Goodman. The New York Times, January 31, 2010. There are over 120 million electric bicycles in China, and now Chinese makers have got behind the technology, they are driving growth in other world markets.
There is some more progress, an electric bicycle is not a “motor vehicle”. That means that signs that say “no motor vehicles” do not prohibit electric bicycles. It would help if they defined electric bicycle someplace. And they finally do.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
