Wroom is a fun and unique application that allows you to make your bicycle sound like a sports car or a motorcycle. Developed by Firesoft Oy, this Android app adds an element of humor and excitement to your cycling experience.

Using the accelerometer on your phone, Wroom determines how fast you are pedaling and changes the engine sound accordingly. It even simulates gear changes for a realistic experience. To maximize the loudness, you can connect your phone to a Bluetooth speaker.

Setting up Wroom is easy. Simply adjust your sensitivity and engine sound preferences within the app. It's important to place your phone in your pants front pocket, as the sound is based on the movement of your leg. Once everything is set, kick-start your bike or tap the screen to start the engine.

Whether you want to turn heads or simply have some fun, Wroom is the perfect companion for your bike rides. When you're done, just tap the screen to turn off the engine.
