How long does it take to recharge?
The typical time to fully charge the on-board Lithium-Ion battery from an empty or discharged
state to full capacity is 3.5 hours. It uses a standard micro USB charging cable provided with the
product.
How long will it hold a charge when it is off?
The unit does not use any power when OFF. We observed during testing that the charge lasts
for weeks.
Will it work going downhill?
Our bicycle light senses any change in ground angle and recalibrates for that angle. An example
is downhill mountain biking. The light recalibrates in approximately 1.5 seconds when you start
going downhill, recalibrates for the new angle, then continues to measure any new angle
change. To our knowledge, this is the only bicycle brake light with this capability.
Why does the flashing pattern look like it is changing?
We designed our flashing pattern to not repeat over a 12-second interval. An automobile
taking the typical time to overtake or pass you on your bicycle will not see the pattern repeat.
Why? Because our brains expect to identify patterns quickly and begin to ignore them. We
draw more attention to you and your bicycle by not having a simple flash pattern but rather
one that is similar to what emergency vehicles use. Want to look even more like an emergency
vehicle? Mount two Stoptix Bicycle Brake Lights on your vehicle and put them in flash mode.
Is there plan to make a smaller version in the future?
No. Our light is 2.0 inches across flat-to-flat intentionally and by design. It does not need to be
this large to accommodate our circuit or the battery. We insisted on making it larger than our
competitors’ products because a larger effective area makes your bicycle more visible. A great
deal of research went into developing the required minimum effective area for lights on
automobiles and motorcycles. Why would you dispense with all that research data for a
“blinky” light? We started our company working in automotive and powersports and you
benefit from as a cyclist from our company’s unique approach.
Why is the lens not red?
We use an optical diffuser instead of a lens. This not only spreads the light to 140 degrees
output but it also homogenizes the light so it appears to be uniformly lit across the entire face
of the light. Our light is opaque off-white when OFF and uniformly red when ON. Emitting
white light is wasteful when only red light is needed for tail and brake function. Emitting only
red light means our light can operate for a longer time on the same battery.
Why can’t it be attached with elastic straps?
Our light is an instrument using an accelerometer to measure deceleration by measuring g-
force. You can’t mount an accelerometer using elastic straps because the motion of the bike
