questions with answers...
Q: How do I open my light to install batteries?
A: Just take a coin (a nickel works well), stick it into the slot on the side of the light where the two halves of the light meet, and twist. We have tutorial videos here.
Q: How do I know if the light I order will provide enough light to see with?
A: Click here to visit our light finder.
Q: How can I mount my tail light to a rear rack?
A: We make a tail light rack bracket that fits all of our tail lights except the Blinky 1, available here.
Q: I've got an aero seat post. How do I mount my tail light?
A: We offer a mount that will fit aero seat posts specifically and we also have a rubberized mount that will fit round posts larger than 31.8mm diameter.
Q: My light doesn't turn on, what's the deal?
A: Open your light and make sure the batteries are aligned correctly to the positive and negative markings inside the light. Also make sure that you have tried a new set of batteries in case the originals are dead. If your light got soaked, take out the batteries and let it dry for a few hours.
Q: My BRT Strap does not turn on consistently. How do I fix it?
A: Sometimes the battery can become unseated from the contacts. First, try pressing the side of the case opposite the red button very firmly with your thumbs to try and pop the battery back into place. If this doesn't work, open the battery compartment by removing the four small screws and bend the battery contacts towards the battery. View the tutorial video here.
Q: How should I take care of my NiMH or Li-Ion rechargeable battery?
A: Your battery can last for years if you make sure to disconnect it from the light head when not in use and make sure to charge it completely (1) before its first use, (2) after every use, (3) before extended periods of storage, and (4) once a month when not in use. This will ensure that your battery doesn't "starve" and lose its charge past the point of revival.
Q: Can I put a 15 watt bulb in my 10 watt light?
A: Yes, but you will experience shorter run times (as the light will draw more power). If your 10 watt lighting system was purchased after January 2005, it already is a 15 watt system! We made a running change and are still using old packaging that states 10 watts.
Q: My light clamp is too small to fit on my handlebars. What can be done?
A: A clamp that is adjustable to oversize handlebars (31.8mm) is available here.
Q: Will my bike still fit on my roof rack with fenders installed?
A: Most bikes will still fit on roof racks with fenders installed. We must caution, however, that driving on the highway may cause breakage due to the high wind force causing the fenders to vibrate dangerously.
Q: Modifications: Can I paint my fenders? Drill holes in them? Cut them in half?
A: We can't tell you what can and cannot do, but we never recommend any modification to our products (doing so will void all warranty). If you chose not to take our advice, please be forewarned that modifications might compromise the products structural integrity. We will not be responsible for modifications gone awry.
Q: Sometimes my computer resets itself when I am riding, or when I take it off of the mount. What's up with that?
A: It sounds like there isn't solid contact between the battery and the contacts. Remove the battery and bend the contacts located below and to the side of the battery in towards where the battery sits.
Q: Why doesn't my mode button work?
A: Usually if the mode button does not work it is because one of the red buttons is slightly stuck inside the case. The best way to cure this is to use either a small screwdriver or an unbent paperclip and gently pry the red button back towards the center of indentation where it sits.The button should pop back into place and appear flat within the computer case.
Q: Why does my LCD screen show the time, but won't register speed when I ride?
A: The sensor and the magnet must be within 2 mm, which is pretty darn close. The magnet must also be aligned with just ONE of the round dots (lines on the Protege 9.0 wireless) on the sensor. DO NOT align the sensor between the round dots or the computer will become angry. On the Protege 9.0 Wireless computer, make sure the sensor is within 21 inches of the computer head.
It's also possible you need to change the battery. The battery in the computer head should last approximately 6 months or 1500 miles (depending on usage and more like 2500 miles for the wired computer) The battery in the sensor (for wireless computer ONLY) should last twice that long. The time will still be displayed in a computer that has a weak battery - there's just not enough "juice" to pick up the sensor signal.
Q: Why is the screen unreadable with my sunglasses on?
A: If you wear polarized sunglasses you may not be able to read the screen or a small dark spot may appear on the screen. This is because we already polarize our screen for easier reading and the double-polarization effect can obscure the data on the screen.
Q: What if the bracket is too small for my handlebars?
A: A bracket that will fit oversize (31.8mm) handlebars is available here.We also now have a stem mount available for our wireless computer - you can purchase just the bracket here.
Q: How do I change the time on my computer without resetting the entire computer?
A: Push the mode button until you see the time displayed on the bottom line of the computer. Push the red set button on the back of the computer (upper left). On the screen the hour digit should be flashing. Push the mode button to get to the correct number and push the set button to choose the hour and move on to the minute digits.
Q: Why does air come out the wrong hole in the pump head when I am pumping?
A: Sometimes the mechanism inside the head that automatically switches to the correct hole gets stuck. Strike the pump head against the palm of your hand or a hard surface to loosen things up. You can also give it one hard, abrupt pump stroke and that will have the same effect.
Q: What if the seals on my pump hose or head wear out?
A: Our pumps are all rebuildable. You can purchase replacement parts here.
Q: Will your CO2 cartridges work with other manufacturers' inflators?
A: Yes, in most cases. Our cartridges are tested to the highest standards for durability, safety and reliability. They contain pure CO2 with no oils or contaminants. Please note, if you use a Genuine Innovations inflator that accepts non-threaded CO2 cartridges, you must use Genuine Innovations non-threaded cartridges. Planet Bike threaded cartridges are compatible with G.I. threaded inflators.
Q: I forgot the combination on my lock. Is there a master code that will open it?
A: No, there is no master code.
Q: How can I order replacement keys?
A: To order replacement keys:
1) We need to know the number on the key.
2) We need to know what lock it came from.
3) We need a photo of the key for manufacturing reference.
4) Cost is $4 per key and takes about 9 weeks to manufacture.
5) We need your name, address and phone # for shipping, as well as credit card info for payment.
6) Key orders are placed once a month on the first working day of the month.
Q: Can I buy several locks that all use the same key?
A: No, that is not possible. An easy solution is to buy resettable combination locks and set them all to the same combination. Click here
Q: How do I mount my EcoRack?
A: The part with the lip points forward and the two stays connect to the corresponding holes on the seat stays of your bike. If no such holes exist, you can wrap the rubber coated u-clips around the seat stays and bolt the rack stays onto those. The bottom of the rack bolts into the holes that are located where your chain stays and seat stays meet near your rear axle.
Q: Will you sponsor my bicycle-related event?
A: We prefer to sponsor events that improve conditions for cyclists. If your event fits the bill, or even if it doesn't (we make exceptions) email Jay with a description of your event.
Q: Where does the 25% percent of profits that you donate to bicycle advocacy go?
A: We sponsor scores of organizations through grants and product donations. Find out more here »
