For avid bike riders, especially in metropolitan areas, it is often difficult to keep a bike secure when it is parked on the street. The safest locks are often extremely heavy and bulky, and lightweight locks often don’t do the job.

Enter the Ellipse Smart Bike Lock from Lattis, a happy techy way to keep a rider’s investment safe.

The Ellipse is solar powered and comes with a built-in accelerometer that is able to alert the owner if it is quickly moved or adjusted by a possible thief thanks to a companion app.

Opening the lock with the app is also easy: just click open on the smartphone, and it unlocks easily, making it easy to allow another person to move and lock the bike with sharing privileges from the owner.

Lattis created the lock and app with bank-level security to ensure the lock is safe from hacking. The solar panels are also a cool feature, as only an hour of sunlight gives the lock a full charge for up to a week.

The Ellipse Smart Bike Lock is set to retail for $200.
