Can I trigger the turn blinkers while wearing thick winter cycling or ski gloves?

Yes. The 5 conductive-fabric touch ribs are tuned to respond to a broad gloved press or even bumping Pad 1 against your jacket chest so you barely move your hand.

How do turn instructions reach the sleeve from my phone?

The ESP32 BLE controller bridges navigation notifications over Android BLE or iOS ANCS (Apple Notification Center Service) without needing your phone screen unlocked on the stem.

Is the sleeve washable after sweaty summer rides?

Yes—slide the LED and BLE core out of the inner pocket in 5 seconds and hand-wash the spandex/nylon compression sleeve in cold water.

Bike & E-Scooter Handlebar Turn Chevrons on a Forearm LED Sleeve

With both hands on the bars, your forearm streams animated amber turn chevrons and a shrinking 32-column distance bar over Bluetooth — turn direction stays in your lower peripheral vision while a gloved tap fires a 100-foot night blinker ($199).

Turn cues in peripheral vision: Amber chevrons and a 32-column distance bar stream to your forearm while both hands clamp the grips.
Glove-friendly taps: Bump a pad against your chest or press with a gloved thumb to fire a 4-second amber turn strobe.
Ships as 1 of 50 modes: Pre-loaded as Turn-by-Turn Chevron; rewrite any message in the Sleeve Studio app.

Watch the 8×32 RGB LED matrix and 5 conductive-fabric touch pads running cycling, running, navigation and commute modes on the forearm sleeve. Concept render · simulated 8×32 display · first production run of 500 units.

Why Taking a Hand Off E-Scooter Handlebars to Check Maps Is Dangerous

Both hands stay on the grips: Small e-scooter wheels destabilize instantly the moment you ride one-handed to signal a turn or read a watch.
Readable in real traffic: High-visibility amber pixels sit in your lower sightline instead of a 40 mm watch face at 18 mph.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
