This may be my favorite feature on my bike. Yes, I can stop, unclip, punch in my garage code to open the door, circle back around and ride between the cars to my bike shop. I could stop at the door, take out my phone and open the garage with the app. But it is sooo nice rolling into the driveway, pressing a tiny button on my bar-end, and just coasting right in.
The DoorMate is from 12 Speed Products. It's about the size of a chapstick and weighs nothing. It captures the garage code just like the HomeLink in your car. Literally took a min. to program and 30 seconds to "install". Installation means removing the bar end plug and replacing with the opener. Really.
Edit: $39
