Purpose

Problem Want to know how much calories you burned

while riding your bike, but don’t want to be confined indoors?

Current Solutions Expensive, complex systems

Our Solution The Bicycle Energy Measurement System

(BEMS)

What is BEMS

BEMS is a simple, user friendly product that measures and computes the energy expended by the cyclist

BEMS

Features

User-friendly interface Easy to enter personal information

Eg. Weight of cyclist & bike

Display Velocity (km/h or mph) Distance (km or miles) Power (W or kCal/h) Energy (kJ or kCal) Trip duration Average velocity/power

How does it work?

Sensor package measures Speed Inclination

Display unit Inputs personal info Outputs energy expended

Operation concept

Measures Speed &

Inclination

Calculates data from Sensor

PackageCyclist Pedals

Sensor Package Microprocessor

Display Output

Cyclist enters weight using the display unit Start pedaling Energy spent displayed on LCD screen

System Overview
