Keyless Entry

Ellipse doesn't require a key; it locks and unlocks with a tap of your phone. You can even set Ellipse to unlock automatically as you approach your bike, so you never have to take your phone out of your pocket.

Secure Backup Access

The touchpad is a novel and personal way to interact with your Ellipse. Key in a personal code of up to eight characters to lock or unlock your Ellipse if your phone runs out of battery. When it's not in use, the touchpad goes dark, so no one even knows it's there.


Ellipse's built-in solar panel automatically charges the battery as you go about your day. Normal use in outdoor or indoor light will keep the battery charged. In the rare instance the battery runs out, you can charge it by exposing Ellipse to light or through a micro-USB charger.
