I Bike KNX app for smartphones logs your bicycle trips. The data you record is sent to regional transportation planners in the Knoxville area and can be used to make our region a better place to ride.
By learning about what routes you prefer, ongoing efforts to improve bicycling conditions in the area can be strategically enhanced.

-GPS track of each trip you record along with the mileage and duration of the trip.
-Reports of calories burned and pounds of CO2 emissions saved
-Report problems along your route such as potholes, obstructed bike lanes, etc

The I Bike KNX app uses your smartphone’s GPS to record information about your bicycle trips. When you start the app, information about the route you take is recorded, along with the speed and time of day. Optional information including the purpose of your trip can be specified. When you complete your trip, the data is sent to the Knoxville Regional Transportation Planning Organization where it will be aggregated with hundreds of other trips to build a picture of the routes most frequently used to travel in the area.

The I Bike KNX smartphone app is a collaboration between Civil and Environmental Engineering researchers at the University of Tennessee – Knoxville and the Knoxville Regional Transportation Planning Organization. The project aims to improve bicycling safety and use the valuable data it provides to understand how improvements to area roadways can best meet the needs of area bicyclists.

Please note: continued use of GPS running in the background can dramatically decrease battery life.

Customer Reviews

Useful app


This is a great idea for improving cycling conditions in our area. I was using it just for short trips such as errands and getting someplace but plan to include all my rides. I had a problem with the app and someone responded right away! Turned out the issue was something I did but it's good to know my message was taken seriously.

Can't upload bike rides


I've taken two bike rides using this app. Neither one will upload. When I click on My Trips, it says "Found unsynced trips" but every time I try to upload them, the app crashes.
