What is TheBikeShieldApp?

Simple and revolutionary, TheBikeShieldApp is a First Layer Crash Avoidance Technology mobile app which establishes communication between cars, motorcycles and bicycles that are sharing the road. When using this app, car drivers get an acoustic signal that warns them about approaching motorcycles and bicycles. These signals raise drivers’ awareness and reduce distracted maneuvers that may result in a fatal crash with motorcycles and bicycles.

The BikeShield API

Integration of BikeShield B2V Communication channel to other apps.

We have developed the APIs to open our Bike-to-Vehicle (B2V) communication channels to other road apps. That includes apps for bicyclists, bikers and car drivers. We are connecting everyone because we are all people and we are all sharing the same roads!

Bike Share Programs

Ideal because they have their own app and they are delimited to a specific part of town. The recently launched program MiBici from Guadalajara (Mexico) is the World's first program to incorporate the BikeShield in its own app, becoming the first World’s bike share program with a B2V system. It is expected that by the end of the year, the program will have 20,000 users. We are also in conversations with Mexico City, Barcelona and Santiago de Chile. We want to do the same in your city.

Road Navigation System Apps

If you have developed or you are developing apps for car drivers we can also open our B2V communication channels to you. With our API, your users will get warnings when cyclists or motorcyclists are getting too close.

The BikeShield Bus

The World’s First Bike-to-Bus (B2B) Communication System

We have developed the BikeShield Bus, tailored for bus drivers. It makes a lot of sense to develop the implementation of the BikeShield API to bike share programs and the BikeShield Bus in parallel. Both programs are normally managed by the local Administration, which is responsible for creating and building sustainable and safe transportation systems. And let’s face it, buses will not get smaller and bikes will not get bigger. So let’s use technology to enhance road coexistence.

It makes sense.

How many times have you been driving your car and all the sudden a motorcycle passes you, splitting lanes, catching you by surprise? Imagine if at that precise moment you decided to change lanes without paying too much attention…?

  • Creates a virtual Shield with just one tap
  • Simple and sleek user interface
  • Very easy to share with your contacts

How it Works

Motorcycles and Bicycles

As you ride, all the cars surrounding you that have the Shield activated will get an acoustic notification 5 to 10 seconds before they can even see or hear you. But remember, that should not make you lower your guard. Always be very careful.


When you begin driving your car, your phone will automatically activate the app using it's accelerometer. When you get an acoustic notification, just keep driving as you locate the bicycle or motorcycle. Simple, isn’t it?

About Us

The TDG Company is a startup created in 2014 by a group of enthusiastic cyclists and bikers from Los Angeles, California. That’s right, we love being on two wheels. We want to breathe cleaner air, we want to live in a less congested area and we want everyone to be happier. But, we want to do it safer.
