Bike Light Set with Bicycle Speedometer, USB Rechargeable Bike Computer with Loud Bike Bell, Waterproof Bike Front Light and Tail Light, Bicycle Headlight Taillight for All Mountain & Road Bike

Works absolutely great for me. High power headlight is super bright. If I set the tail light to a marquee or blinking mode, and the headlight to the orange light mode, it uses less electricity and the charge last over 18 hours. With little traffic on country roads these are the modes I use. One push of a button and the headlight is in super bright mode if I hear cars. Yes, the wires do not have stress relief fittings coming out of the housing, but a dab of silicon seal fixes that and they are then very robust. Very loud horn.

I needed a flashlight for my old Schwinn, and found this on Amazon and thought I would give it a try. I would have to say I am pretty impressed! I have installed wired speedometers on bikes before so it didn't take too long to get it on, and it works pretty well. Here are a few pointers to make it work well:1. Make sure you measure the circumference of the outside of your bike tire (easiest way to do this is to mark a line on the sidewalk and roll the tire in a straight line for a whole rotation - then take the distance between the start and the end). You will need this distance (in cm) for the initial setting.2. Make sure the magnet on your spoke is aligned with the bottom of the sensor - (other side of the wire - see my installation image) - inside the sensor there is a small toggle switch that the magnet engages - you can hear the switch engage if you move the magnet near that part of the sensor. The gap should not be more than 3mm.3. The horn is LOUD!!! I did not expect it to be so loud - Not sure how many decibels but I am sure it is close to the 120 db advertised. I made the mistake of testing it in my garage and jumped thinking I set off an alarm or something.4. The light is pretty adequate and bright - even has a cool all yellow setting for daytime riding.5. The horn connector uses the USB port, so be careful connecting any USB cable attached to a computer that has data signal - it will set off the horn!6. The kmph measurements are much more accurate - mph was a little iffy for me, but I am okay with the speed in kmph.Thats about it! I think for the price this is a great gadget for your bike - a flashlight, horn, speedometer/computer in one (and it comes with a nifgy taillight as well!) Best part is that both lights use internal rechargeable batteries so no need to spend money on batteries!

Installing components was not an issue ; however, setting up an accurate milage and speed is proving to be a pain. Installed on 26 inch wheel assembly and default for milage set up is 26 inches or a circumference of 208 centimeters. It is not close to being accurate --going to try and adjust to obtain accurate speed and milage.

I have been looking for a Bike Light w/Speedometer & found this Combo Set that also has a USB rechargable cord (-vs- Batteries) & also works at night...exactly what I wanted & a Tail Light,which is beneficial at night. After charging the Headlight -I was sadly disappointed when I went to attach it to my Bike, only to find that the Light had not charged. I attempted to charge it again, unsuccessfully, so will be returning it & am hoping the Light I received was just a "glitch" & they can replace it with a working Head Light that will charge. My Review reflects the Tail Light working ~

all parts of this work perfectly and exceeded my expectations for the price.the plastic contruction feels strong and reliable and have held up durring rides in the city.two complaints.the mount is streachy rubber and can slide a bit if not on the tightest setting.the magnetic spedometer needs some way of adjusting the depth of the magnet. cause ive tried this on 2 bikes of different sized and neither of them get accurate speed. at all..

I did not like this item the wires fell out of their spot, after 3weeks of use, and it doesn't work anymore.

The media could not be loaded.  It works perfectly. Would recommend

Best deal you can get for the price plenty bright and loud also great flashlight for many purposes
