Reactive lights for safer rides
When you face moments of increased risk on your commute (e.G. At junctions, filtering traffic or high-stress intersections), ace reacts by automatically flashing brighter and faster to make you more visible to other road users. It also shines powerfully both in daylight and at night-time, helps you be seen from over a mile away, and gives you 200° of side visibility.
- Help create better cycling infrastructure for everyone by sharing your rides with transport planners, or providing them with direct feedback.
- Receive theft alerts if your bike is moved without you, automatically send crash alerts to a nominated contact, and get low battery notifications.
- Control and customise your lights by changing their flash mode, brightness level or flash patterns.
- See your cycling stats or pair ace with a compatible garmin device thanks to ace’s Ant+ technology.
