Electric Bike - Choosing a Suspension Fork When selecting a suspension fork for your electric bike you need to make sure it is the recommended length to match the frame it is going on. If you purchase a complete bike the fork that comes with it will already be a good match. A fork that is too tall for the frame will change the handling characteristics of the bike and add more stress to the head tube than it was designed for. This could...more

Electric Bike Batteries - Why You Shouldn't Completely Discharge Them If you are thinking about buying or building your own electric bike then there are some things you should know to help make maximize the life of your expensive battery pack. DOD or depth of discharge is one of these things.When calculating how much battery capacity you need for the distance you want to travel on your bike you should only plan on discharging the pack to 80 percent DOD. Most battery cycle life (how many times it can be recharged) specifications are based on 80% DOD. If you discharge more than this each time the cycle life can be reduced. The batteries will also slowly lose capacity over time so the extra 20% capacity gives you an added buffer zone before you need to replace them. Don't forget to add any electrical loads from accessories that are powered from your battery pack such as lights and a heated jacket if you intend on using one. Something else to consider is your battery capacity will decrease as the temperature gets colder. You will have approximately 15% decrease in capacity when riding in temperatures close to or below freezing so you may need a larger capacity pack if you...more

Electric Bike Batteries - Three Important Things To Know If you are thinking about building an electric bike you will obviously need a battery pack. Many people get confused when they started shopping for batteries because there are so many different types and various specifications for each brand of battery. Hopefully I can help clear up some of the mystery for you to make you decision easier. The first thing to consider is what voltage battery pack you need. The top speed of your bike depends directly on the voltage of the battery pack, the higher the voltage the faster the bike. If you want a motor just to assist you while you pedal your bike continuously you will probably only need a 36 to 48 volt battery pack. On the other hand if you want to use the bike more like a motorcycle and cruise around at high-speed without pedaling something in the 72 to 100 volt category would provide much better performance. You also need to make sure your motor and controller are rated for the voltage of battery pack you are using. Next thing to consider is the battery capacity which is how long a battery will last on a single charge. It is measured by how many amp-hours (Ah) it can...more
