With VeloAppie, you can easily control your Veloretti e-bike (Ace or Ivy). This is an unofficial app and is not affiliated with the manufacturer. However, the app is actively maintained, so you can keep riding independently. You can view bike data, control the light, change the bell sound, send weather information to the bike display, and show navigation prompts on the display. Key features: • View battery, odometer, firmware, max. speed, and other bike data • Control light, bell sound, and assistance level • Automatically turning on the lamp around sunset • Send weather to the bike display, including an optional clock mode (see time on display) • Bike navigation on the display (improved!) Features may depend on firmware, bike model, location services, and an active Bluetooth connection.
