E-bikes represent one of the best balances of personal utility and environmental performance of all forms ofurban road transport. This research will help promote the adoption of e-bikes and quantify how e-bikes can bemost appropriately used and to reduce emissions in Canada's urban centres can benefit, and will better positionExro to capitalize on the growing e-bike market using its advanced electric motor.Exro's electric motor is based on a new and patented control technology that shows great potential in achievinghigher efficiency over a wide range of operating speeds. The electric motor uses Dynamic PowerMangementTM (DPM) technology that senses changes in motor load and switches on the fly between eitherparallel or series arrangements of the multiple windings within the motor to achieve optimal efficiency over awide range. This project will adapt and implement this technology in e-bikes and assess its performance in avariety of driving cycles representative of actual use in various urban environments including personalcommuting and drayage. E-bikes require fairly significant variations in both speed and torque from theirelectric drive-train and Exro's DPM technology offers the potential of significant performance gains. Theproposed study will allow systematic assessment of the technology and identify critical developments requiredfor its commercial adoption in e-bikes.
