An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider’s pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and the lighter varieties can travel up to 25 to 32 km/h (16 to 20 mph), depending on the laws of the country in which they are sold, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany, they are gaining in popularity and taking some market share away from conventional bicycles,[1] while in others, such as China, they are replacing fossil fuel-powered mopeds and small motorcycles.[2][3]

The California section indicates the need for an M-1 or M-2. Not completely correct, if the motorized bicycle, moped, scooter, motorcycle, has 3 wheels (attached sidecar or trike) then a Class C is enough, and no special motorcyle endorsement is needed.

“This is the beginning of a multi-year shift away from regular pedal to electric bikes,” Jump Bikes CEO Ryan Rzepecki told CNN Tech. “When people first jump on an ebike, their face lights up. It’s exciting and joyful in a way that you don’t get from a regular bike.”

GenZe e-Bikes come in sizes to fit every shape. Height is usually the best gauge of size, but we also recommend comparing your inseam to the standover height if you’re considering the Sport or 201 models. The 200 series also comes with adjustable handlebars and a 4-way adjustable seat to get the perfect fit.

Add a device to control speed.  One example is a three speed switch.  Some controllers have a plug for it, or there are types that just modify the throttle signal.  If your controller comes equipped with a cycleanalyst plug, then the CA can have its speed limiting function set to 20-MPH.  Lastly, some controllers have a jumper wire that limits potential speed. In most cases this jumper wire, when connected, will result in speed a lot slower than 20-MPH. So that may not be the first choice.  However you get it done, it beats having to comply with the moped laws, particularly if you have no drivers license.

Pedelecs are much like conventional bicycles in use and function — the electric motor only provides assistance, most notably when the rider would otherwise struggle against a headwind or be going uphill. Pedelecs are therefore especially useful for people living in hilly areas where riding a bike would prove too strenuous for many to consider taking up cycling as a daily means of transport. They are also useful when it would be helpful for the riders who more generally need some assistance, e.g. for elderly people.

The most common questions regarding e-bikes – is it cheating? The short answer is, no! Anyone who has owned an e-bike will tell you that you end up using the same amount of energy, sometimes more, but the amount of effort depends on the individual and what they want from it. In reality, because you’re free from the usual limitations of cycling, you’ll ride faster and for longer.

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.

In most jurisdictions, the bikes are limited to 20 mph. Many can be ridden up to 50 miles before running out of electricity and can be recharged in two to four hours. In price, they run from several hundred dollars to many thousands.

Some e-bikes have an electric motor that operates on a power-on-demand basis only. In this case, the electric motor is engaged and operated manually using a throttle, which is usually on the handgrip just like the ones on a motorbike or scooter. These sorts of e-bikes often, but not always, have more powerful motors than pedelecs do.

China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[69] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][70] This boom was triggered by Chinese local governments’ efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[69] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[70] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[69][70]

If you are concerned about the speed and power of an electric bike, pay attention to the motor size. Electric motor size is measured in watts and usually ranges between 250 and 750. When deciding on the appropriate amount of wattage, think about factors like the weight of the rider and the desired speed and terrain for the bike. If your child will mostly be on a flat surface, lower wattage should suffice; if they are planning to ride up and down hills, look for a bike with a larger motor.

Lithium-ion polymer batteries have the same electrical properties as standard Li-ion batteries, but the material can be shaped more easily. There’s the potential for some interesting designs, though we’ve yet to see them.

I’ve had 3 throttle bikes and have been riding a pedelec for 2 weeks now, and so far, I liked the throttle. I’m basically a cyclist who likes to keep the pace up going up hills, so I used to ride unassisted a of the time, but that’s not really possible with the pedelec. It would be better if it had a 0 setting so you could still use the throttle override, but the only option is to switch the whole thing off. And I agree with Dan, it’s just another thing to go wrong, cost money and add weight. I’ll bet in my case it detracts from the range. Imagine if they told you that you couldn’t switch off cruise control in your car!

Vintage Electric offers a few e-bike options for getting around California, and for its latest ride it has enlisted one the Golden State’s most iconic figures. The Jeff Clark Signature Cruz has the legend’s fingerprints all over it, and offers fellow surfers a stylish way to cruise to the beach.

Thanks for helping a little Southern California startup become a global company. A company that can not just hang with the big boys, but lead the way. Thanks for helping us stay true to our roots. For embracing innovation. For realizing that style and substance aren’t mutually exclusive.

Yes, There Are Age Limits: According to Portland State University’s TREC Transportation Insight for Vibrant communities, as of December 2015, at least 40 US states and Canadian provinces had a minimum operator age for e-bikes, typically 14 or 16 years of age. In Alberta, 12 year olds can operate an e-bike, but in Quebec, you must be 18.
