Currie Ezip Trailz Electric Bike
bikeengines.org 24 volt electric motor. On a scale of 1-10, I’d give this bike an overall 8. My main issue is the loudness of the motor. No, electric bikes aren’t all silent. Range is probably about 10 miles and depends on a lot of factors. An extra battery pack can be bought and attached on the right side for increased range. Best of all, the bike uses no gasoline. Charging takes no more than 3 hours. This is the lowest priced of all ebikes and no matter how much you spend on one, even thousands of dollars, you’ll get about the same range out of all of them. If you spend big bucks on an ebike, it would be only for status, and people won’t notice anyway.

Motorized electric bikes are sometimes also referred to as e-bikes. It is just like a bicycle but has an attached electric motor which is recharged by plugging it into an electrical outlet. They are very popular in China while relatively new in Europe and the United States. For cyclists who want a little help with climbing hills it is an ideal choice.
There are various reasons to buy an e-bike. They are an environmentally friendly modes of transportation and they do not require spending money on gasoline. Even a current bicycle can also be converted into an electric bike with the help of an electric conversion kit. It is the safest, cheapest and quickest option. You will no longer have to worry about the increasing price of fuel, where to park, or deal with traffic jams. They are suitable for people of all ages, including kids and older adults. The lack of gas prevent pollution ot the environment, but the bike is mobile enough to cruise around town in and can even prevent you from having to buy a car in big cities.
You may be asking yourself, how do I go about purchasing an electric bicycle? Well here are a few key points to consider before making your purchase.
1. Look for a light weight bike. If its weight is heavier then it is more difficult to pedal when the motor is not being used.
2. Before going to purchase an e-bike the purchaser must consider what type of motor to use. The speed of the bike depends on the power of motor.
3. An e-bike battery usually lasts between 12-30 miles. The battery power is drained considerably more when used for climbing hills, so keep that in mind. Pay attention to battery life when purchasing your bike.
4. The cost of an electric bike ranges from 0 to ,500. So by considering the features of the bike you can purchase an electric bike which suits you the best.
5. The best and most important thing before buying an electric bike is to take one for a test ride. There are various models and manufacturers of e-bikes, with some of them being: Currie bicycles, Rayos, Ultra motor, Urban Mover Bikes, Prima Power bikes etc. with different features. Before buying an electric bike compare the features of different bikes and then purchase the one that suits you best.
Most of all, have fun riding your new bike!

What Maintenance Is Involved For My Electric Bike
What Maintenance Is Involved For My Electric Bike
Basically there is no ongoing maintenance of electrical components other than recharging batteries. Many of our bicycles use the latest generation Brushless Hub Drive motors where there are no contact point inside the motor that can cause wear and tare. It is advised to keep bicycle clean at all times. Under normal use, motor doesn’t need readjustment and maintenance except that its outer surface needs cleaning at regular intervals.
How e-Bikes Work is by assisting your pedaling. Electric bikes are everyday bicycles with an added battery-powered electric motor. Although capable of pushing you along without your help, electric bikes perform noticeably better when you pedal. The average “couch potato” who normally rides at 10 mph can ride at 15-20 mph using the same effort. He can also expect a range of 10 miles, with a recharge time of several hours. Do you remember that easy pedaling after you get your bike up to speed? That’s the cruising feeling you get all the time with an electric bike.
Power, when activated by a switch on the handlebar (power-on-demand) or in response to your pedaling, gives you an immediate, nearly silent push. When you release the switch (or stop pedaling), the motor coasts or “freewheels” – like when you stop pedaling a regular bike. Standard bicycle hand brakes and gearing round out the controls.
“Power-on-demand” means just that – no pedaling required! Although all electric (or “electric-assist”) bikes are designed to work with your pedaling, power-on-demand allows you to break the rule. Most systems offer a variable speed control, although some are simply on/off (like the yellow switch pictured). It senses you are pedaling. And it’s “power output to pedal pressure” ratio is often adjustable. Most people find 250-watt motors adequate for their needs, although folks with steep hills may want more power. Some bikes offer through-the-gearing power assist – i.e. the force of the motor goes through the bike’s gearing system – which provides better hill-climbing and top-end speed than direct drive systems with the same size motor.
How e-Bikes Perform depends on many factors. The most important factors are listed here with the (generally speaking) most important at the top:
terrain (number and incline of hills)
e-bike speed (range at 10 mph is 8 times as far as at 20 mph)
wind conditions (going 10 mph against a 10 mph headwind feels like 20 to the bike)
pulling a trailer (which is like pulling another bicycle)
correct tire inflation (under-inflated tires slow you down)
battery size (measured in volt-amp-hours)
weight of rider and baggage
motor/controller/drive system efficiency
As you can see, battery size and system efficiency rank near the bottom. The speed you go makes a big difference in how far you go.
All else being equal, range is a function of either 1) battery capacity (amp-hours X volts) or 2) speed and ease of recharging (high-power chargers provide lots of miles in less than one hour). There is a close relationship between battery capacity (A/hrs) and both weight and physical size (total volume). Generally speaking, the bigger the battery, the greater its capacity. For hill-climbing, expect about 3 feet of elevation gain for every volt-amp-hour.
All else being equal, speed is a function of motor (watt rating) and controller. Most scooter motors are capable of higher performance characteristics than the controller allows.
