Leveraging my experience at Grin Technologies, I engineered a custom electric bicycle optimized for urban commuting and efficiency testing. The build integrated commercial off-the-shelf components with custom telemetry solutions.
Component Specifications#
- Frame: Montague Paratrooper (Folding Mountain Bike)
- Propulsion: Nine Continent 2807 Direct Drive Hub Motor (optimized for regenerative braking).
- Power Storage: AllCell Technologies 36V 11Ah Li-ion battery (utilizing Phase Change Material for thermal management).
- Control System: ASI BAC-350 Field-Oriented Controller (FOC) for silent, efficient operation.
- Lighting:
- Front: Cycle Lumenator (1000 lumen output, tapping into main pack voltage).
- Rear: Electrolight (Integrated brake light).
- Telemetry & Human Machine Interface:
- Display: Cycle Analyst V3 (Primary dashboard for tracking Ah consumed, Watts, Speed).
- Data Logging: Custom-solder HC-05 Bluetooth Module bridge to transmit serial data to the EV Trip Analyzer web app.
Note: This vehicle served as the primary testbed for the EV Trip Analyzer software.
