Design Concepts

Design One | Power Storage Ability

Problem
The generator stops when the bike is not in motion, cutting off the power delivery to the light. Thus putting the driver's safety at risk when he/she is about to cross a road in the dark.

Solution
Power is harnessed from the generator to recharge a battery pack, and then electricity is delivered from the battery pack to the light.


Design Two | Fully Wired Closed Circuit

Problem
Traditional generators use the bicycle frame to ground the circuit. However, many modern bicycles use composite materials that do not conduct electricity.

Solution
A closed circuit is created with wires connecting to both the positive and negative terminals of all the components.

Design Three | Detachability, Charge Indicator, Power Button

Problem
From our market survey, these features are preferred by most users.

Solution
A closed circuit is created with wires connecting to both the positive and negative terminals of all the components.
