Current Solutions
Expensive, complex systems
Our Solution
The Bicycle Energy Measurement System (BEMS)

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

6. Features User-friendly interface Display
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

7. How does it work? Sensor package measures Display unit Speed
Inclination
Display unit
Inputs personal info
Outputs energy expended

8. Operation concept Cyclist enters weight using the display unit
System Overview
Cyclist enters weight using the display unit
Start pedaling
Energy spent displayed on LCD screen

9. Sensor package Houses Attaches to the fork of the bike
main power supply
optical encoder
accelerometer
signal conditioning
circuitry
Attaches to the fork of the bike

10. Display unit Mounts on the handlebars
Processes data from the sensor unit
Main point of communication with the user

11. Market Recreational Cyclists
Monitoring physical output is part of a healthy lifestyle
Fact:
33 billion dollars are spent annually in the United States on weight-loss products and services
