The Boost-R includes an integrated battery fuel gauge that provides visual status updates regarding remaining capacity.
Yes, the unit features an IP67 rating, meaning it is protected against full immersion and heavy road spray.
The light provides 200 lumens in flash mode and 75 lumens in constant mode.
Using the USB-C port, charging is optimized for fast power delivery, though exact times vary based on the wall adapter used.
It is designed to fit most standard seatposts; check for specific aero seatpost adapter availability if your bike has a non-round frame geometry.
Ensure the USB-C cable is fully seated and the charging source is providing adequate power; wait 15 minutes before attempting to power on.
Ensure the light is mounted level to the ground; if tilted too far upward or downward, the internal accelerometer may not calibrate correctly.
Ensure the sensor area on the rear of the light is clean and not obscured by mud or reflective stickers.
Mount the Boost-R securely to your seatpost using the provided bracket, ensuring the lens is perpendicular to the road surface for accurate sensor detection. To maintain the IP67 waterproof seal, ensure the USB-C port cover is firmly pressed into place after every charge. When cleaning, use a soft, damp cloth and avoid harsh chemical degreasers that could damage the lens housing. Avoid leaving the battery completely depleted for extended periods to preserve cell health. If you are mounting this on an aero seatpost, verify your mount compatibility with Exposure accessories, as the standard bracket is optimized for round posts.
