48V 1000W Electric Bicycle Conversion Kit with Optional 21ah Battery

Why do we use a Double Walled Rim and heavy duty 36 Gauge Spokes? ? 
In the beginning we tried various kits and many of the brush less motors were very good motors. The problem with most of the conversion kits available are that they are spoked incorrectly, use a single walled weak rim., have spokes that are the wrong length causing the spokes to be bent in an "s" shape. Simply put bicycle wheels were not made for this type of torque on them and on occasion you will need to tighten your spokes until they finally "seat" themselves. 

FRONT VS REAR? 
FRONT elctric bike kits= easy to install, easy to maintain. This is the best for Balance if you are using SLA batteries on a rear mounted rack because of The weight. 
REAR electric bike kits= harder to install, BUT for big motor, =More safety Installation only for the very Mechanically inclined or professional. Only enough space for 7 rear speeds Max (we ship with 5 speed). Bad balance if you are using heavy SLA Batteries...Good for wheelie's lol but bad and unsafe balance with SLA. 
Good points are that they are a slightly more natural feeling ride when using Lightweight LiFePO4 batteries.

We are located in Changzhou city, Jiangsu, China. We are just one hour from Shanghai by high-speed train. 
Our factory is certified by CE, SGS, CCC, EEC and other related certifications. Our products are reliable and durable. We export to Europe, the USA, Canada, Southeast Asia, Australia and many other countries. At CNEBIKES we always pay close attention to good customerservice and a logical service. 

Q: What is the electric bike conversion kit? 
A: The kit is designed to transform your standard bicycle(manual pedal power)to an electric-powered by a motor and battery pack. 

Q: Will the conversion kit fit my bicycle? 
A: The conversion was designed to fit 90% of the bicycles, and you can check your bicycle fork(the two metal pieces that attach the wheel to the bicycle) to be sure. You will need at least 100mm for front wheel and 135mm for rear wheel. 

Q: If my bicycle meet your standard, how can I choose to install front wheel or rear wheel motor? 
A: A front hub kit is normally much easier to install than a rear wheel kit since you don't have to worry about gearing or derailers. When riding, the rider can easily see the front wheel and respond quickly to problems such as wheel spinning. 
Rear wheel drive has the advantage of better traction which is great for hills and inclines. And because the rear frame dropouts are normally stronger than the front fork dropouts, a rear wheel can handle more torque and increased power. 

Q: How fast will it go? 
A: The speed would be decided by the motor power, controller and battery spec. According to different countries rules, we provide 25km/h for EU and AU market, provide 30km/h for other market. 

Q: How far can I go on one charge? 
This varies depending on usage, your specification will affect the your battery performance and life. And mostly of the battery have a cycle life of more than 700charges. 

Q: Do I have to pedal to assist the motor? 
A: There are two kinds of modes available, throttle controller and pedal assist. 
Throttle controller means you use a throttle to control power and speed. To get started, simply twist the throttle to accelerate and hold it to maintain speed. 
Pedal assist means once you start pedaling, a torque sensor picks up your movement and power integrates seamlessly while you ride. Just pedal and go. Once you use the brakes or quit pedaling, the power is deactivated and you need to pedal again (lightly) to re-activate pedal assistance. 

Q: How long does it take to recharge the battery? 
A: Usually it takes 4-6 hours. 

Q. When should I recharge batteries? 
A. The battery can be charged after every ride. We do recommend that every 20th charge that you run the battery flat and give it a full charge. 

Q: How should I store my battery? 
A: Store in cool dry place, you should fully charge your battery before storing it. 

Q: How can I get the best battery performance and range? 
A: Pedal while the motor is on, start the motor after the bike is moving, use the motor mainly to climb hills, and don't use the motor while you are going downhill.

Cylindrical fenders are simple and effective for a range of ships and applications. They are commonly used in areas with small tides and where low hull pressures and reaction forces are not significant. Cylindrical Fender is one kind of very popular marine rubber fenders because of easy installation and operation, versatile and highly cost effective. With hollow cylindrical design, they can be produced to almost any length and diameter as required, matching to almost any application, including berths serving both large and small vessels such as general cargo, fishing vessels and tug vessels. They can be installed horizontally, vertically or diagonally and can be adapted to wharf corners.For all the different types of vessels, to ensure a safe and linear berthing, cylindrical fenders are generally used and recommended for all types of use. These cylindrical fenders are very economical and easily to install to the berthing installations.
