  • when you need a golden bicycle bell, this is it

    posted by ndftz2

    nice satisfying ding.. feels more polite than my previous 'ding
    for a gold bell. this works and affixes easily.
    where I live (brisbane, Australia) you get a $50 fine if you do not have a bell.
    for much less than the cost of the fine, i have a cool looking bell with great acoustics.
    i would have preferred an all silver or brushed metal finish bell but now that i've gone the golden path, i need to get other golden accessories for my ride
    get it here if you need it. probably the best bell on DX
  • Great alarm for the price

    Very convenient bike alarm. Siren is loud enough. I was impressed by it's sensitivity which can be adjusted in three different levels. Fits perfect under seat. Battery cover is nicely protected when mounted on a seat tube.Certainly worth the money.
    It would (probably) be better if manufacturer uses two AA batteries instead 9V block one.
    This is nice little bike alarm which come in handy when your bike is near you and you don't want to look for the thieves all the time. You should use keylock also, this is just audible alarm.
  • Lightweight alert device

    It is useful if you leave your bike unattended in places where people is nearby. If anyone wants to steal it, it is triggered.
    It sounds for a period only, so it won't annoy excesively the occassional neighbors.
    Sensitivity adjustment works.
    Really easy to use.
    Get one if you want to scare a pottential thief.
  • Cheap & actually useful

    A really loud vibration activated alarm you can use on your bike, motorcycle
    or anything. Turn key to green and its armed. If you (or a thief) bump it or
    what its mounted to it will sound a loud alarm until you turn the key to red
    to disarm it. It reacts to small vibrations, not movement/acceleration. So
    if you move it really smooth it wont go off. To turn it off without the key
    you would have to smash it or demount it and then unscrew battery
    compartment (the one screw on the back both closes battery compartment and
    mounts the bracket to the alarm).
    * I have not tried to let it sound the alarm till it stops (the sound is
    quite painful), so i don't know how long it lasts (claimed 35 secs).
    * I don't know if it will be broken by rain/water. Probably it will work if
    you let it dry.
    * Where the bracket is mounted to the alarm there is two extra screw holes
    in the mounting bracket. I recommend finding two screws that fit here to
    stop the alarm from spinning around the big screw.
    * I mounted it to the luggage carrier of my bicycle by bending the mounting
    bracket around a bar. It was the only place on my bike with a thin enough
    A cheap and actually very useful alarm. I use it when i ride my bike to the
    shop and park it outside while I'm inside. Much quicker than locking it. It
    seems to survive quite bumpy rides. Although it broke once. But i opened it
    and could see what had happened. The one connector from the lock didn't have
    contact with the circuit board anymore. I soldered it back in place and now
    it works again!
    So the bottomline is: Although it has poor build quality, it works as
    intended, has many uses, is quite useful, is cheap and is not hard to repair
    if you have a soldering iron.
