BikeSense smart handlebar system

Technology & Mobility Studio – BikeSense

The Technology and Mobility Studio at Pratt Institute, taught by Professor Rebeccah Pailes-Friedman, explores the intersection of technology, design, and human movement, focusing on innovative solutions that enhance mobility in all environments. Students engage in hands-on projects that integrate cutting-edge technologies to create products that address real-world challenges. Through a combination of research, ideation, prototyping, and testing, students developed a deep understanding of how technology can improve the safety, efficiency, and experience of movement in complex settings. 

This project, BikeSense, by students Brooks Butler & Mehul Bhargava, introduces a smart handlebar system that incorporates technology driven by user-centered design to enhance safety and awareness for cyclists in urban environments.

Project Overview

Cycling in urban environments faces significant safety challenges due to heavy traffic, inadequate bike lanes, limited driver awareness, high population density, and restricted space. To address these issues, BikeSense aims to develop an innovative bike handlebar that enhances safety by improving cycling awareness for both the rider and those in the surrounding environment.

BikeSense enhances rider safety by detecting nearby obstacles and alerting the rider through consistent vibrations as objects approach. It also increases visibility on the road with integrated turn signals and headlights.

Design Solution

Powered by an Arduino system, the BikeSense handlebars incorporate key technologies, including ultrasonic sensors for obstacle detection, haptic feedback systems for rider alerts, and LEDs for turn signals and headlights. Pogo pins are utilized for both data transfer and power delivery to the handlebars’ electronics. Magnets have been strategically placed to secure the detachable battery pack, ensuring an easy and convenient charging experience utilizing a USB-C charge port.

Outcome

Cycling in urban environments presents pressing safety challenges stemming from factors such as heavy traffic, inadequate bike lanes, driver awareness gaps, high population density, and constrained space. The BikeSense handlebar system improves cycling safety by increasing the rider's awareness of their surroundings, reducing the risk of accidents in high-traffic areas. The functional, full scale prototype demonstrated the effectiveness of these features, with haptic motors activating when objects were detected within 4 meters, providing consistent vibrations as the object approached.
