To facilitate the development of new electric bicycles, a computerized electric bicycle testing facility has been created in this study. Electric bicycle standardized testing cycles have also been developed. Three different methods for testing electric bicycles have been investigated in this work; these methods are: the Electric Bicycle Velocity Testing Cycles (EBVTC), the Electric Bicycle Grade Testing Cycle (EBGTC), and the outdoor Electric Bicycle Road Acceleration Testing Method (EBRATM). All three methods are found to provide useful results. The EBVTC provides detailed vehicle performance measures for a given drive cycle of a specific area, such as New York City. It is particularly useful for designing electric bicycles to fit a specific market. However, due to the present open loop control to match the velocity profile, time consuming calibration for each test electric bicycle is needed. With the addition of speed sensor and a closed loop control system, this issue can be resolved. The RacerMate Computrainer and a dedicated control unit built using a Basic Stamp 2 microcontroller form the electric bicycle dynamometer needed for the EBVTC tests. The EBGTC is simple and effective, giving useful acceleration information, as well as performance values for comparison purposes. The EBGTC takes very little time for a complete test (less than 30 minutes for set-up and testing). The method could also be used to determine the grade limit of each electric bicycle. The EBGTC is programmed into the Computrainer by using the Computrainer Pro PCI software. It does not require the dedicated control unit since no complex driving cycle is involved. The electric bicycle road acceleration testing method (EBRATM) is very quick (under fifteen minutes) to complete an acceleration test for an electric bicycle, but tests, especially those in terms of repeatability can fluctuate due to varying outdoor environmental conditions. It is observed that road testing is very inexpensive, and gives realistic performance values at the time of testing (even though the results will most likely be different if the same test is initiated the next day due to wind, temperature, etc.). The EBRATM also does not presently have the ability to observe the power output of the electric bicycle. The AEBPS design enables most bicycles (including full suspension) to be easily and quickly transformed into electrically powered vehicles. The AEBPS prototype is constructed and tested in outdoor conditions on and off road; it is found to fulfill all expectations. During off-road testing the AEBPS proves to be extremely successful. The Heinzmann hub motor has more than enough torque to climb most hills; the motor controller can also handle the large loading, and never shut down.
