Care and Maintenance for Your New e-Bike

You should in general take care of your e-bike the way you would with a regular bicycle
by keeping it dry, clean and the moving parts well lubricated. You should also avoid
parking your e-bike in exposed areas whenever possible.

You should check the effectiveness of the brakes before each use.

1. Your e-bike is designed for regular road use for a single person. Using your e-bike for extreme maneuvers, such as extreme off-road use, jumping, or carrying excessive load will damage the e-bike and could cause serious injury.
2. Do not use high pressure water streams to clean your e-bike, as water might seep inside the motor or the wiring compartment and cause rusting of electrical parts or short circuits.
3. Avoid parking your e-bike outside when there is rain or snow. At the end of a trip where there was rain or snow, bring the e-bike inside and use a clean, dry towel to eliminate any wetness.
4. Be sure you do not lose both keys. If you lost one key, you should immediately make a copy as a back-up. If you lost both keys, you will be unable to remove the battery from the e-bike.

• Use only the supplied charger to charge your battery. Do not use an unauthorized substitute. If your charger is lost or damaged, contact your dealer to order a replacement.
• Do not open or alter the battery or the battery charger.
• Do not place the battery near fire or corrosive substances. Do not immerse in water or other liquids.
• Avoid subjecting the battery to high temperature, such as directly under the hot sun, for prolonged periods of time.
• Do not connect (short circuit) the two poles of the battery.
• After much use, your battery's charge holding capacity will decrease. If you find that your battery does not hold sufficient charge even for short trips, you should contact your dealer to order a replacement. Under normal use, the battery will undergo 1000 charging and discharging cycles.
• If the battery will not be used for an extended period of time, charge it fully and recharge it every 3 months. Store it in a cool place.
• Your e-bike battery is engineered with precision for high capacity and a long useful life. We do not recommend that you use it to power other electrical devices. Improper use of the battery will damage the battery and shorten its useful life, and may cause fire or an explosion.

How to Assemble Your New e-Bike

Stand the main body of the e-bike on the kickstand. Insert the stem of the handle bar subassembly into the steering column that is at the front of the main body frame. Make sure that the fork (that will hold the front wheel) is pointing forward, and orient the handle bar accordingly. Insert the stem all the way and tighten from the top using the big hex wrench.

Make sure that the fork from the steering column is pointing forward. Place the front fender within the fork: locate the small projection with a screw hole at the top of the fender, fit it to the bolt at the back of the base of the steering column; attach the supports (two on each side) to the base of the fork using four small bolts (supplied). After all five points (the dorsal point and the 4 support points) are properly attached, use the multi-wrench to tighten.

Make sure that the fork from the steering column is pointing forward. Place the front wheel within the fork and between the two brake pads on either side, seat the axial stem properly within the receptacles at the tips of the fork, and tighten the nuts with the multi-wrench. Make sure that the front wheel moves freely and does not wobble from side to side. Reposition the wheel and re-tighten if necessary.

You may need another person to help you with this step. The front brake is installed and assembled except that the cable was relaxed to allow the installation of the front wheel. After properly installing the front wheel, the cable can be tightened again.

Using the small hex wrench, loosen the screw that tightens the cable so that the cable is completely free to slide back and forth. Arrange the several pieces of metal and rubber along the brake cable in their correct positions by referencing the rear brake. Squeeze the brake arms so that the brake pads are against the wheel, but leave sufficient clearance of 1/8 inch on each side (you might want to insert some scrap material, such as a piece or cardboard, between the wheel and the brake pad to ensure there is sufficient clearance). Pull the cable at the end to take out all the slack, tighten the cable by means of the small hex wrench.

Test the brake by lifting the front of the e-bike and setting the wheel in motion (turn it) and apply the brake at the handlebar to stop it. If you could not set the wheel in free motion, or if you could not stop it by apply the brake, you need to re-adjust by increasing or decreasing the clearance.

Caution: Do not operate the e-bike until you are satisfied that both the front and rear brakes are operational.

(Note: Installing of the light and dynamo assembly is optional. Some people prefer battery-powered LED light as opposed to dynamo-powered light.)

Attach the light and dynamo assembly to the special receptacle on the right side of the fork for the front wheel. Tighten slightly. The front light has a wire already connected to the dynamo. Connect the loose electrical wire that runs from the rear light to the same connection point at the dynamo. Operate the lever to check that the two dynamo positions are properly assembled to the effect that the dynamo can engage and disengage from the front wheel. Tighten the nut and bolt. Test the installation again by checking that, in the engaged position with the front wheel turning, the lights are turned ON.

Insert the pedestal stem of the seat into the seat column of the main body frame, use the built-in lever to tighten.

Attach a pedal on each side of the crank, tighten with the multi-wrench.

Inflate the tires to proper pressure.

At this point, your e-bike is a completely functional bicycle, although without any battery operated function as yet. Check all tightening points to make sure. Take a short ride. Adjust the height of the handlebar, and the height and the tilt of the seat, if necessary, for maximum comfort.

Remove the battery from the box and turn the switch to the ON position. The LEDs on the battery should light up to indicate that the battery is functional and that there is an appreciable amount of charge in the battery. Install the battery by first seating it at the base at an angle and then gently push it into a vertical position. You need to insert and turn the key anti-clockwise to lodge battery snugly into the top bracket. You should also see the charge level indicator at the handlebar will also light up. Remove the key, make sure the battery is in position and not movable. Turn OFF the battery.

Remove the charger from the box, attached the power cord and insert that to any wall outlet. Insert the plug at the end of the smaller cable into the charging terminal of the battery and start charging. The charging terminal is on the side of the battery opposite to that of the switch. The LED on the charger glows RED while charging and glows GREEN when charging is complete. The battery should be turned OFF while being charged. When the LED on the charger turns Green, disconnect the charging cord and cover the charging terminal with the metal cap. The battery has a series of LEDs as charge level indicators. There is a similar series of LEDs on the handlebar. If a battery is installed on the e-bike and turned ON, the LED indicators will show the charge level of the battery.

You are now ready to start using your e-bike.

How to Buy an Electric Bike

Step 1
Choose a style that suits your commute. Sure, you want something sleek. Your bike should also be comfortable and reliable.

Step 2
Decide how much you can spend. Look for quality but don't break your budget. Prices can range. Think of your purchase as a long-term investment.

Step 3
Compare the stock at different bike shops. Don't be shy! Ask the salespeople about the brands. Find out how long the batteries last, and how long they take to charge. Also ask how much replacements cost, and how often--if ever--they need to be changed.

Step 4
Test ride the bikes you like. Check the handbrakes and the ease with which it shifts. See how it handles turns. Imagine sitting on it for long commutes. The seat should be comfortable.

Step 5
Make sure the bike fits your body. When you stand, there should be 3-6 inches between your crotch and the frame.

Step 6
Before you buy a bike, check online for the best prices.

Step 7
Choose the bike that suits your needs and enjoy the ride!

How to Determine Which Type of Bike to Buy

When you go to buy a bike, you will find that you have a choice between mountain bikes, road bikes or hybrids. But which bike makes the most sense for you?

Step 1
Decide what you want to do with the bike. Where do you want to ride? How often? Is comfort a top priority, or is performance more important?
Step 2
Buy a mountain bike if you want to ride off road. Mountain bikes also make great city bikes. If you don't plan to ride off road, simply switch to smoother tires.
Step 3
Buy a road bike if you want to go fast, and if you only ride on the pavement. Road bikes are light and efficient, but people who don't ride very often generally find them uncomfortable.
Step 4
Buy a hybrid if you want the upright, comfortable riding position of a mountain bike, and the efficiency of a road bike. Hybrids are great for city riding, commuting, and light trail riding.
Step 5
Consider a one-speed cruiser for a quality low-cost, low-maintenance bike. Cruisers are great for running errands and getting around a college campus. But watch out for long hills!

How to Learn to Ride a Bike

Everyone knows how to ride a bike. However, we all had to learn to do it at some point. Here are some tips on how to teach your child to ride their bike.

Step 1
Make sure to get protective gear for your child. Accidents can and will happen, so be prepared for them.

Step 2
Make sure your child has driven a bike with training wheels before attempting to go without them. Training wheels require a certain amount of skill to navigate the road, so they are beneficial and necessary to the process.

Step 3
Next, get your child psyched for the impending ride. Encouragement can and will go a long way.

Step 4
Get a bike that your child is comfortable with. Make sure that the bike is the right size and height for the child.

Step 5

How to Pack for a Bike Tour

Step 1
Put your saddlebags, called panniers, on the bike. Clip the hooks on the panniers to the top of the rack, with the elastic on the bag's back facing the wheel. The larger panniers hang from the rack over the rear wheel and the smaller ones from the front rack.

Step 2
Line each pannier with a garbage bag in case of rain.

Step 3
Pack items tightly, filling the garbage bags inside the panniers with camping gear, cooking supplies, spare clothes and tools. Balance the weight so that one side of the bike is not heavier than the other.

Step 4
Put on the handlebar bag. It should hang from a clamp that came with the bag, and it attaches to the center of the bike's handlebars.

Step 5
Fill the handlebar bag with sunglasses, sunscreen, wallet, snacks and other items that require frequent access. If your bag has a map pocket, slide your folded map into the appropriate section.

Step 6
Strap your sleeping bag and tent to the rear rack with bungee cords or nylon straps. The cords should run from the front of the rack, over the bag and tent to the rear, and then back. Fasten tightly.

Step 7
Shake the bike from side to side - when everything is mounted - to see whether anything falls off.

How to Pick a Bike for a Toddler

A bike is a toddler's first real sign of independence. It is similar to when a teenager gets his first car and it's exciting for him and for you. The question, though, is how to pick a bike for a toddler with all of the choices available out there. Just follow these guidelines.

Step 1
Consider your toddler's height. Take your toddler to the store with you so that you can properly fit him for his bike. When he sits on the seat both feet should touch the floor.

Step 2
Check the age range recommended for the bike. Your child should be in that age range. Bikes come in different sizes for each range so if your child is big or small for his age the bike should accommodate his needs.

Step 3
Think about where you will be riding. Bikes come designed for either the road or the trail. Road bikes cannot be ridden safely on a dirt trail.

Step 4
Take into consideration your child's maturity level. What type of bike he should ride is going to depend on what he is mentally ready to use.

Step 5
Allow your child to pick out the theme of her bike. Toddler bikes come decorated with Barbie, Spiderman and other childhood heroes. Allowing your child to pick her own bike really makes it her own.

How to Plan a Bike Tour

Take the extra time to plot out your bike tour, and your journey down the road will be much more enjoyable.

Step 1
Get an updated road map, a topographic map and weather information for the area you intend to tour.

Step 2
Decide how far you're comfortable riding each day, keeping in mind that you'll be riding for several consecutive days.

Step 3
Decide whether you'll camp or stay in hotels, and make appropriate reservations.

Step 4
Arrange for a friend to accompany you in a car if you don't intend to carry your gear.

Step 5
Identify secondary and tertiary roads using a road map. Consult travel guides for scenic routes.

Step 6
Call local transportation authorities for shoulder information, and avoid roads with gravel or no shoulders.

Step 7
Check prevailing wind conditions, if any, and try not to plan a ride that keeps you heading into the wind.

Step 8
Schedule rest days (days with fewer miles) after especially long rides.

Step 9
Plan night stops at the base of hills rather than at the top and before entering areas with narrow roads or high traffic.

Step 10
Identify stops for water, food and mechanical assistance, and plan accordingly.

How to Select the Right Battery!

Some of our customers are confused to choose the right battery for themselves. Here, we'd like to share our ideas.

Step 1
You need to know the battery part number and the fit model of your machine. Only when these are both advise on the item description that the battery could meet your need.

Step 2
You also need to know the battery type of your battery and battery charger. For example, when you want to buy a Ni-MH power tool battery, but your battery charger is only for Ni-Cd battery. It will be a waste of money since the Ni-CD charger is not fit for the Ni-MH battery.

Step 3
You need to take a look at the dimension too. Some of the high capacity battery will be bigger than the low capacity OEM battery. Hope these tips may help!

How to Use an Electric Bike

Step 1
Adjust the seat to fit your body size. The seat should be high enough that your legs are slightly bent when you are in the down stroke of pedaling. Balance and comfort are the keys to enjoying the ride.

Step 2
Be sure the battery is fully charged. Then turn on the power switch.

Step 3
Begin pedaling, as this will conserve the battery charge. It takes a lot of battery power to start from a dead stop. Use the electric feature only when you need to get up a tough incline or simply need a break from pedaling.

Step 4
Engage the battery power by using the throttle on the handlebars. It will disengage when you quit pedaling or take your hand off the throttle. Some bikes have pedal-activated power, which engages when you are riding up a steep incline.

Step 5
To increase your speed, first pedal to your desired speed and then engage the throttle. This will conserve your battery power for those tough hills. For pedal-activated bikes, the power will automatically engage when you begin the incline.

Step 6
Apply brakes to slow down or stop.

Step 7
Turn off the power switch when done riding.

Racing Bicycles - Light and Fast

The Tour de France has existed for over 100 years. It is the most well-known bicycle race in the world, bar none, covering more than 2200 miles over the course of 23 days. Although it takes place primarily in France, its route often passes through neighboring countries. It is a test of endurance, skill and some of the most technologically advanced bicycles ever made. The bikes used in the Tour de France are racing bicycles, specially designed to deal with the numerous demands cyclists must put on them during a race. The Union Cycliste Internationale (UCI), the cycling association that oversees all competitive cycling events around the globe, defines the requirements of a racing bicycle.

Racing bicycles are designed to do one thing-go fast. To that end, there are two important characteristics to this kind of bike. One, it is light weight, which means that the cyclist has to put in less effort to propel the bicycle; and two, its makeup is as aerodynamic as possible, up to and including the position assumed by the cyclist. It is the combination of these two attributes that allows the racing cyclists to attain the speeds they do for the amount of time required.

Every component of a racing bicycle is designed to weigh as little as possible. The wheel rims, for example are usually made of aluminum alloy, a very lightweight material. Alternatively, some bicycles have carbon fiber rims, which weigh even less. Most such rims have triangular cross-sections, which allow for greater aerodynamic efficiency. To further reduce weight and increase aerodynamics, many racing bicycle wheels have as few spokes possible. Some high-end wheels have spokes with bladed cross-sections, which further reduce wind resistance. The tires of racing bicycles are lightweight, narrow and have a thin, smooth tread. They are inflated to a very high pressure, which increases the potential speed of the bike.

The term "groupset" refers to the mechanical components of a racing bike, which exclude the frame, fork, wheel set, bars, stem, pedals, saddle and seat post. Derailleur gears are an essential part of any groupset. These gears consist of a chain, multiple sprockets (wheels with teeth), and a mechanism that shifts the chain from one sprocket to another. This system is what allows the racing cyclist to adjust his or her speed and effort according to the terrain. The shifting mechanism can be located on the bike's stem, handlebars or frame, but total integration systems utilize combine brake and shift levers that allow the cyclist to shift gears without moving his or her hand. Derailleur was developed in the late 19th century and aside from the introduction of total integration, they have changed little since that time.

There are a number of different manufacturers who produce complete bicycle groupset, including Shimano, Campagnolo and Mavic, although the first two are probably the most well known. The various companies have different design philosophies, and cyclists are often loyal to one brand over all others. As with the non-groupset components, the mechanical elements of a racing bicycle should weigh as little as possible. As a result, carbon fiber has become popular in the manufacture of such elements. They are used for shifters, brake levers, cranks and parts of derailleur.

Safe Cycling Tips

Cycling can be an enjoyable pastime. It can also be a great way to beat the congestion on your way to work or school, and keeps you fit and saves money. Following a few simple road safety rules can keep you out of trouble, and help keep you and your bike safe on the roads.

Riding Tips

* Know the cyclists highway code
* More usefully, read Cycle Craft by John Franklin. This guide shows you how to ride a bike confidently and safely in today's traffic conditions. It is the basis for the National Cycle Training Standard syllabus.
* Or consider getting some cycle training, which meets the National Cycle Training Standard syllabus. The old-fashioned Cycling Proficiency Test is not enough - the NCTS is tailored to modern needs.
* How to not get hit by cars!!
* Where possible choose a route that you can cope with. You may wish to avoid busy roads and junctions. On cycle paths be aware of pedestrians, especially the elderly and the very young.

* Be aware of your surroundings by looking and listening. Always give clear signals for your safety and for that of others.

* Always look behind you for other vehicles before turning and changing direction and signal clearly by sticking out your arm wide on the direction you are about to travel.

* Never go through red traffic lights, and think carefully about then to go through an amber signal.

* Avoid undertaking large vehicles particularly at junctions as you may find them turning into you, or the space between you and them narrowing suddenly. Long vehicles turning left may swing to the right first.

* Never cycle after heavy drinking or taking drugs.

* Make sure lights and reflectors are kept clean and in good working order.

* At night, use lit front and rear lights and has an efficient red rear reflector. Wear something that is light colored, reflective or fluorescent to be seen by other road users.

* Keep you bike in good working order: regularly checking brakes; keeping the saddle and handlebars properly adjusted; making sure gears and chains are working properly and are oiled; checking tyres are in good condition and inflated to the correct pressure.

* Wearing cycle helmets.

Where to Race Your Pocket Bike

While many Pocket bike owners race their pocket bikes at competitions and go-kart tracks, others simply enjoy zipping around on their pocket bikes for recreational purposes in open local areas. There are many options for legally racing your pocket bike with friends and in organized competitions.

A racing sanctioning body has been established to promote racing in North America called NAPRA, the North American Pocket Bike Racing Association. Go-kart tracks offer a road racecourse that is perfectly scaled to Pocket Bikes You can give your local go-kart track a call or get in touch with NAPRA itself to see if any tracks or leagues are offering racing in your area.

Major kart tracks across the country have adopted pocket bike racing, and there are sure to be more as the national interest in pocket grows with every passing day.

Outside of pocket bike competitions, you can ride your pocket bike on private property in enclosed courses. Here are some guidelines for recreational pocket bike riding: find a clear, open area that allows for high speeds, be sure there are no major obstacles or obstructions that could cause harm or injury, ride on a relatively smooth surface to maximize control, and steer clear of public roads and pedestrian-heavy areas.
