Waterproof 7/8"- 1 1/8" Handlebar Luminous Dial Motorcycle Clock for Dirt Bike Motocross Yamaha Kawasaki Honda Suzuki Harley Davidson (Black)

So far, very nice and attractive clock. We'll see how well it keeps time and how well it stands up to bicycling vibration and shock. No instruction sheet so here is what you do with what you get: (1) Pull the knob out to set the time; then push it back in. Just like a wristwatch if you know what those are. (2) Peel off the paper on the two rubber strips and apply to the case and bracket grooves. The radius of the grooves is larger than any handlebar, so these strips are needed to grip and avoid scratching up the handlebar. (3) A thin double sided adhesive disc is provided. It has no purpose. You can either (a) throw it away, (b) remove the paper on one side and stick it to the bottom of the case, or (c) use it as-is between the clock and case. There is nothing wrong with having a thin gap there. (4) Drop the clock into the case and rotate it to where you want it. Secure it with one of two set screws provided. (The second set screw is a spare.) (5) Align the case and bracket on the handle bar and tighten with either the long or short allen head screws, depending on the diameter of your handlebar. Be sure to position the case such that you have access to the set screw with the small allen wrench. Note: the set screw threads are not straight threads. They or the threads cut into the case are slightly tapered. Thus the set screw goes in tight and WILL NOT back out with vibration. (Somebody did something right! Straight threads would have rendered this thing useless.) (6) Position the clock in its final position and tighten the allen head screws evenly with the large allen wrench, compressing the rubber strips. Voila, a beautiful clock! Another reviewer has posted excellent instructions for changing the battery. Note: This appears water resistant (can tolerate splashing or a sprinkle) but I doubt it is waterproof. There is no gasket around the bezel, though one could easily make one. It is not sold as waterproof.

Fits my bike Moscow plus great , easy to read and to mount , come very fast ( 2 days) looks good. Very happy with this purchase

El reloj está bien solo que no se ilumina en la noche

This works very well. All the hardware that comes with it for attaching it to your handlebars is a decent size and very sturdy. I haven't had an issue with this. The bright numbers make it easy to read even in low light conditions

really like this bike clock. I use it on an etrike. Looks and works great, well worth the low price
