Abstract

Kit that can be attached to any ebike to increase functionality.

Features such as turn signals, Speedometer, led lightstrip for wheels, speakers, trip meter/odometer, rear object sensor, and security alarm.

This project allows improved safety by clearer comunications from bike riders to other vehicles as well as entertainment.

Challenges and Proposed Solutions

Software


Bluetooth interfacing with a phone

Learn Bluetooth protocols from online sources

Mobile app development

Either recruit someone who knows app development or one person dedicates time to learn this

Handle proccessing from sensor and accessory input

Navigate the datasheet of the sensing devices and may have to create protocols to interpret all the information

Future Challenge


Hardware


Reliable power supply

Build a rechargable lithium-ion battery pack that can handle the requirements of the device

Designing a pcb to manage the sensor, accessory, and connect with bluetooth

Study the datasheets of the sensor we use in order to interface it correctly with a microcontroller

Calculations for speed and which sensor to use

Determine a technique and way to calculate speed

Adapting ebike power supply

Try to develop universal adapter

Prototype


We plan to implement an LED Matrix board that displays behind the bike. This will be connected to a microcontroller which is in turn connected to a phone via bluetooth. We will be able to turn on and off turn signals and send messages from the phone to the board. We plan to work on each aspect of the protoype together. Beyond the protoype, we will split the work when it comes.
