These controllers are cheaper but come with no guarantees and no manual. Kelly makes good controllers here are some links: kelly brushed: kelly brushless: Another cheaper option is to use a chinese electric bicycle controller from Ebay. The controller is what ultimately will decide how much current will get pumped into your motor so make sure you are happy with its current rating. Again keep in mind the voltages and currents you want to run on. Here are some great brushless motors from hobbyking: (when ordering from hobby ALWAYS make sure to use PAYPAL payment option) Controller: The kind of controller is specific to wether your motor is brushed or brushless. ![]() Always look on forums for and tips and hints about motors to use. My friend is running 40V on a motor rated for 24V for instance. ![]() However keep in mind most motors can actually surpass their ratings quite a bit. Make sure the motor you select can handle the currents and voltages you select. ![]() Chiquicycle has a 245 Kv motor and i wish it was lower so i could have a better acceleration. i recommend a Kv of less than 200 for a pocket bike. Think of a high Kv being like higher set of gears on your bike/motorbike or car (harder to pedal but faster). It is the "gear ratio" of motors, a lower Kv will generally give a lower final speed but more torque for the same amount of current. A high Kv means the motor will spin faster at steady state but it will also produce less torque per unit current. Kv is measured in RPM/volt and represents the speed that the motor will obtain in no-load conditions. Brushed and Brushless motors have an important parameter to pay attention to this is the Motor Back EMF constant commonly reference to Kv. Brushless motors are generally higher performance but also generally more expensive. Brushed motors are cheaper but they may need more maintenance. Motor: First question is if to use a brushless motor or a brushed motor. Voltages for pocket bikes range from 24-40V and current limits can vary from 20-60A. Before selecting components its important to get a sense of the voltage and current you will be dealing with. The drive has 3 components: the motor, the controller and the batteries. Next is to get an electric drive for your pocket motorcycle. We have a "pocket bike gallery" in cambridge MA, we have all sorts of bikes we can convert so don't limit yourself to a specific brand or style! Make sure your rolling frame (wheels, handlebars, chassis and brakes) are in good condition before you start modifying it. In addition the brake levers/cables can definitely be bicycle parts. Luckily you should be able to find most of these materials in the internet here are some good resources for pocket bike specific parts! Many times you can probably replace the original parts by bicycle parts (Chiquicycle has a bicycle handlebar + bicycle seat). Sometimes you won't have the chain, or the driving sprocket. After you get your frame, take a good look at it and try to find any missing parts. These frames tend to be heavier but more sturdy and their brakes are much much better that child motorcycles. Also there is a lot of pocket bikes that used to be gas and you can easily convert to electric. If you look hard enough you should be able find a couple of used razors for a small cost (<50$). I have helped many of my friends find pocket bikes online and here are the models and brands that most often come up: Razor Pocket Bikes form the majority of pocket bikes Chiquicycle is a Razor MX350 i got from some people that had taken it apart and were about to throw it away. Luckily craigslist and ebay is full of people trying to give away their old pocket bikes because they sons have grown out of them or because the electrical system got toasted by some kid doing burn outs. To hear all the sounds on the road is bigger pleasure than just making noise by your bike.First step in making your own pocket bike is to find the frame. Choppers are recognizable through their sound, and probably around 50% of the people are still like ” Yeah but where is the sound in your electric chopper?” Choppers are about freedom of riding as well, and taking your soul to the road. We hope that you will support this project and check out the build on Ballistic Cycles Facebook page! Custom chopper motorcycle design companies are having a hard time with their customers making transition from Gas to electric. ![]() Imagine how much patience you have to have while making this out of aluminum! motor mounting plate + design check Electric Chopper by Ballistic Cycles Ballistic Cycles E-Chopper Design Look at how many curves this side panel has.
