a light I’d recommend for those of you who strive for a clean modern look and a set it and forget it build.
- Bike Rumor
See and Be Seen, No Matter WhatThe auto-adjusting Radius F1 bike light ensures that you stand out on the road and can visibly see the path ahead.
This smart technology conserves battery life by automatically responding to your cycling activity. No wasted power, no button-pushing required.
The Radius F1 seamlessly shifts its brightness to match your speed, so you always get the appropriate amount of lighting. No manual adjustments necessary.
As you brake to a stop or make a turn, the light automatically switches to flash or pulse mode to increase your visibility. No switch-flipping required.
Biking at Night Just Got BetterHere’s how the versatile Radius F1 improves battery life, visibility, and safety.
Lighting for the Long Haul
After three minutes of non-movement, the light switches to standby mode. Start moving the bike again, and the light returns to default speed-controlled lighting. After one hour of bike inactivity, the light’s power shuts off completely—because nothing is worse than forgetting to turn off your light and discovering it's dead on your next ride.
Brightness Where & When You Need It
As your cycling speed increases, the headlight automatically brightens and projects farther down the road. As you slow down, the Radius F1 dims to ensure optimal visibility where you need it the most. And unlike other speed-controlled lights, the Radius F1 transitions between dim and bright seamlessly, with no jarring shifts in light output.
Extra Safety at the Crossroads
Abrupt changes in cycling speed and/or direction can increase your risk on the road, so the Radius F1 bike light increases your visibility with its safety-enhancing pulse mode. As you brake to a stop or make a turn, the smart light will automatically switch to pulse mode to warn oncoming drivers (and to keep you alert).
Even More InnovationIn addition to automation, the Radius F1 offers top-of-the-line construction and materials.
Detachable Bluetooth Remote
Easily mount the accessible and detachable Bluetooth remote to either side of your handlebar. The remote's positioning allows for quick adjustments to the light’s brightness as you continue to maintain complete control of your bike.
The mount and casing firmly secure the bike light for stability and super-steady lighting without jiggling, slipping, or rotation, even on rough roads. When you want to remove the light, the bracket stays on your bike; simply disengage the lock with a 90-degree turn, and the light disconnects from the bracket—pop it off to charge it or to prevent theft if you head inside.
Hassle-Free Magnetic Charger
Recharge anywhere with the simple magnetic charger — no dirt infiltration, inroads for water, or damaged USB ports. Simply snap the magnet-equipped charger to the light and recharge.
Precision-Manufactured Micro Lenses
Hundreds of micro lenses and a reflector generate consistent illumination over both distant and close-up terrain: spot lighting hits further ahead and flood lighting illuminates a wider area in front of your bike for superior visibility.
Durable and Waterproof
Constructed with rainy rides in mind, the F1's IPX7-rated casing ensures you’ll have long-lasting light, even in the nastiest weather. It’s also impact-resistant from up to 1m, because drops and spills happen to everyone.
No, Radius F1 is designed to imperceptibly change brightness with speed so the rider doesn’t get distracted. With stepless speed-controlled light output technology, the Radius F1 transitions between dim and bright seamlessly, with no jarring shifts in light output. Other speed-controlled bike lights jump between two or three preset light levels, which can be distracting and irritating, especially when your ride involves frequent speed changes (e.g. most urban cycling).
Yes, you can switch between manual mode and auto mode by double clicking the power button. Rely on the light’s auto-adjustment functionality for the majority of your riding, but have instant control over personal lighting preferences whenever you want it.
