Because of the energy crisis, hybrid is the buzzword of the day. With respect to cars, hybrid usually refers to engines that uses electricity and gasoline. The combination of both gets you more gas mileage. For example the 2008 Toyota Prius, a well-known hybrid car, gets 48 miles per gallon as oppose to a comparable 4-cylinder non-hybrid car, say a Honda Civic, that gets 36 miles per gallon. By the way, Honda also has a hybrid version of the Civic and it gets 45 miles per gallon. The point is hybrid technology allows you to cover more grounds for a given set of resources, gasoline in this case.
In the cycling world, the term hybrid refers to bicycles with electric motors . Yep, that's traditional push pedaling made easy with electricity . Instead of more gas mileage, you get more miles pedaling and best yet, you don't have to buy gas (because it's a bicycle).
THE FRUGAL AND HEALTHY CONSUMER
But you're asking why mention gas with bicycles? In the past, at least in the United States, gas prices were never a concern. Up until 2006 or so, Americans were able to buy gas for under $2.00 per gallon. That's practically nothing! Two years later, it's a different story.
In other parts of the world, however, they haven't been so lucky. Europeans have been experiencing gas prices between $5-$8 per gallon for years. But they still get around. Common among their usual transport is a bicycle. You've seen many pictures of common folks getting around town bicycling. Kinda like what we did when we were kids. To get more "mileage", a lot of Asians and Europeans use hybrid electric motor bikes.
Many smart and frugal folks are discovering electric bicycles for short distance commuting to save money. You don't have to pay for gas!
There is another advantage. Since you're pedaling, you're exercising. Makes you healthy. Of course, not everyone is in superb physical shape to be pedaling from one side of the city to the other. But remember, it's a hybrid bike. The electric motor helps you pedal . Therefore you can get in shape slowly, but at the same time do so enjoying the outside.
The price of a hybrid bike may set you back from $500 to $1000 USD. But that should pay for itself within a year if you can save on $50-$70 a month on gas and/or $20-$30 on gym membership.
THE ECO-FRIENDLY CONSUMER
Just as important as saving money, there is a global trend, or at least in the US, to be more eco-friendly. Among others, gasoline is a concern. As you know, burning gasoline emits pollutants that are harmful to both the environment and our health. Transportation that uses less gas (hybrid cars) and no gas (electric car, hybrid bikes, electric scooters) are getting a lot of attention among consumers.
THE CHOICES OF HYBRID ELECTRIC BICYCLES
Though there are quite a few manufacturers of electric bicycles in existence, none of them are quite household names yet. But below are just a handful electric bikes readily found from Amazon, eBay, Shop.com and other online retailers:
iZIP Enlightened Hybrid Electric Street Bicycles
From Currie Technologies, the iZIP is one of the more popular electric hybrid bikes. In one battery charge, it can travel up to 23-30 miles depending on the cycler's weight. Top speed on this 8-gear street bike can be up to 18 mph. As you can see from the pictures, the motor and battery pack are cleverly integrated within the bike's frame. So unlike most electric bicycles, these components are not visually obtusive. The geared hub motor is a brushless DC type encased in an alloy shell. The battery pack is made of NiMH EV Rated Batteries Down Tube Concealed 24V / 9AH Pack (20) 1.2V Rechargeable Cells. There are men's and women's versions of the iZIP bike.
The Euro Electric Bicycle
Designed for urban commuting, the Euro gives you the impression you're gliding to your destination. The rear storage rack makes it easy to run errands such as groceries. The Euro is powered by a 24V 10Ah Li-ion battery with 6 speed Shimano derailleur and a high speed 350W motor. Since the battery is Lithium-ion, it can be recharged over 1,000 times, making it more durable than a typical NiMH battery and SLA (sealed lead acid) battery. Another plus is that Li-ion batteries are recyclable making this electric bike a truly eco-friendly.
Electrec Electric Bicycle
From Ideation Taiwan, the Electrec electric bicycle allows for non-pedal cruising for an 8-12 mile ride using only the motor. Of course, the actual range depends on the terrain and weight of the cycler. This seven speed electric bike comes with a 600-watt high-torque brushless motor powered by a 24-volt, 12 amp-hour battery pack.

A Guide to Electric Scooter Parts
When buying electric scooter parts, make sure they're compatible with your scooter. Many customers make a mistake of buying the wrong parts for their scooters.
Popular electric scooter parts are:
- Accessories - Batteries - Chains - Chargers - Controllers - Throttles
Accessories
There are different kinds of accessories available. A popular choice for a scooter's bag is a large multi-compartment bag than can be placed onto the rear cargo rack. A good bag would be made of a cloth that is high resistant to abrasions, tears and scuffs. Twin Velcro straps should hold the bag securely onto the seat rail or post.
You can also choose a basket to be placed in front. Good baskets would be those that fold out of the way when they're no longer in use. Steel construction is the best with thick enamel finish.
You should have a safety warning bell for your scooter. Some bells are made with compasses too. These bells fit all electric scooter and bicycle handlebars. Bells that have a pleasant sound and are audible are advisable.
A bike motor kit includes self-contained removable power unit, a mounting rack and mounting hardware. You can also buy this kit in local motorcycle stores.
A good headlight would have side light markers that provide additional illumination in the right and left side of the scooter. This is for visibility during nighttime.
Your helmet should cover the back of your head to protect it from backward falls. It should have an air-gulping front, top and back holes. There should be a thick shock absorbent lining inside the helmet that can be easily removed and replaced for cleaning purposes. Most importantly, helmets should be certified by the ASTM F1447 helmet standards or any country's helmet standards.
Even though some states don't require scooter drivers to wear helmets, it is still recommended to wear a helmet no matter how short the distance is.
Additional mirrors are also available as extra electric scooter parts. You can choose a round shaped mirror that is made of chrome plated steel, glass and rubber construction. There should be a safety reflector at the back of the mirror.
Batteries
There is a different range of batteries available for electric scooters. If you know the voltage, dimensions or amp hours, you will be able to choose what battery should you require.
Chains
The #25 chain is the most commonly used for electric scooters. This chain has a " spacing between each chain link and is " wide.
Chain Breakers
Chain breakers don't break the chain despite what they're called. Their function is to remove the pins that hold the chain links together. Master links are used to connect chains together in a continuous solid loop.
Chargers
Intellect Charger - An "Intellect Charger" works with electric scooters and bikes that have a 12 Volt battery or two 6 Volt batteries.
Controllers
There are speed controllers for Chinese-made electric scooters. This part helps control the speed of your scooter from full stop to full forward.
Throttles
The Hall Effect Throttle is the most common type that is used on electric scooters. They work on Chinese-made electric scooters and are sometimes called accelerators, twist bar, speed bar, turn throttle, speed control or derailleur.
Another type of throttle is the on / off throttle. This is used for medium size electric scooters.
5k Ohm Throttles are for high-end and older model electric scooters.

what is the difference btw long cage and short cage derailleurs?
I'm looking for a new rear derailleur for my mountain bike and am seeing long and short cage versions? What's the difference and how do I know which I need?
I have a full suspension mtb.
The length of the cage determines how much excess chain the derailleur will handle. I ran across this explanation a while back and it explains it better then I could.
