Faq Regarding Electric Bikes

Electric Bicycle Faq

1.) How do electric bikes work?

Electric bicycles use batteries as a source of power and a quiet DC electric motor as the driving mechanism. Electric bikes have several modes of operation and can be pedaled, power-driven or pedaled with the help of ‘power-assistance’.

2.) Power-assisted vs. throttle controlled?

Most of the electric bikes and scooters we sell are ‘throttle controlled’ – meaning you use a throttle to control the power and speed at which you travel. But some of our higher-end electric bicycles (IE: IZIP Enlightened models) use ‘power assist’ – which is an automatic mode of operation. Once you start pedaling, power assistance integrates seamlessly while you ride and provides the power you need automatically. No extra hand controls or throttle – just pedal and go. Once you use the brakes or quit pedaling, the power is deactivated and you need to pedal again slowly to re-activate assistance.

For people who prefer full control, a throttle provides a traditional feel and operates just like a motorcycle. For those looking for simplified operation, power assistance does all the work and eliminates the need for a throttle. Operating with power assist is comparable to a "moving sidewalk" at the airport – you do a little work – but move really fast!

3.) How fast do electric bikes go?

The speed of an electric bike will vary based upon several factors. With no pedaling, U.S. law restricts the speed of electric bicycles to 20 mph or less. This ensures you don’t need a license, registration, or insurance to operate your electric bike.

Most electric bikes are rated between 15-18 mph by the manufacturer. But the actual speed will vary depending on rider weight, terrain and road conditions. Some riders will be able to exceed the top rated speeds – while others may experience slightly less power. Keep in mind, U.S. law does not restrict how fast you can travel while pedaling, so most riders will easily exceed the top rated speeds while providing human assistance.

4.) How far can I go on a single charge?

The ‘range’ of an electric bike will also vary upon several factors. One of the main factors in determining how far you can travel on a single charge, is the type of battery you choose. Typically, Lithium-Ion (Li-Ion) batteries have the longest range – anywhere from 25-40 miles per charge (with pedaling) – but cost the most money. Nickel Metal Hydride (NiMH) batteries average between 20-30 miles and are moderately priced, while sealed lead acid (SLA) batteries are the cheapest, with only 15-25 miles per charge.

Other factors which determine the range of a single charge include: rider weight, amount of pedaling, wind, road conditions and terrain (such as inclines or declines).

5.) How long does it take to charge the battery?

Battery charge times will vary between manufacturers, models and battery types. Typically, the initial charge will take 6-12 hours. For routine charging, higher quality batteries (such as Li-Ion and NiMH) will take less time – but you should expect to wait anywhere from 2-6 hours for a full charge.

6.) How long will the battery last?

Battery life will vary depending on the type of battery you choose and how well you take care of your battery. Typically, Lithium Ion (Li-Ion) batteries last the longest – anywhere from 750-1000 charges. Nickel Metal Hydride (NiMH) batteries have a life span of about 500-600 charges, while sealed lead acid (SLA) batteries last between 200-300 charges.

To extend the life of your battery, charge the battery regularly and promptly after each use. If you store your bike for prolonged periods of time, both the batteries and charger should be stored at temperatures above freezing and recharged every four weeks. The longer a battery sits uncharged, the faster the life will be reduced.

7.) What types of batteries are available?

Battery technology continues to improve everyday. Currently, there are 3 main types of batteries used in electric bicycles:

Lithium Ion (Li-Ion) – Lithium Ion batteries are the highest quality batteries available in today’s market. Although they cost the most money, they have the longest life, the lowest weight and the best total range per charge.
Nickel Metal Hydride (NiMH) – NiMH batteries are a mid-range battery type, and in our opinion, the best value. They’re light-weight, have an extended life span and provide great range when compared to the more common (and outdated) SLA battery.
Sealed Lead Acid (SLA) – Sealed lead acid batteries have been around for decades. Although they’re the cheapest form of battery technology, they have the shortest life, the lowest range and are extremely heavy when compared to other battery types.
