There can be some confusion over the terminology. Our brake light is a tail light/rear light. Just like a tail light it lets drivers see you so that they will drive safer. It has blinking patterns as do all tail lights. It is rechargeable and has all the other features of a tail light. BUT, unlike tail lights, it has the ability to notify cars behind you, as you slow down or stop. It get 2-3x as bright when you stop and cars are now aware that you are stopping and they will stop as well. Just like a car brake light. 98% of tail lights do NOT have this feature. We do. It is the best of the best.
It is simple to operate so your kids can use it. It is extremely accurate so has immense value to commuters and urban riders. A novice or a beginner, it offers safety like no other light available.
The answer is simple with some caveats. It will work on an e-bike as well as on any bike. Mounting is the same and the accelerometer will not be affected. I have seen a few e-bikes that have installed a regular brake light that is triggered by squeezing on your hand brakes. We elected not to go this way for two reasons. The more wires you have to connect things, the more potential issues done the line (breakage, erosion, rust, etc and then harder to repair) but the next reason is even more important. These lights are so dim in comparison!! My girlfriend bought a new bike that comes with a brake light. But, she immediately attached the tailgator to her seat post. It is 3 times as bright.
People have aske about mounting on a helmet, backpack, leg, and more. The answers to all those are a resounding NO! The light was designed to be attached to a relatively fixed area on the bike; the seat post being the most obvious. Any other motion, back and forth, up and down will give less accurate readings - and the brake light will be triggered more often. The seat stay is pretty darn stable, not much different than the post, unless you have a seat that has "shock absorbers" or springs, etc. I have such a bike with a variable seat height. The light works but is triggered more often. Gives me more visibility when the light goes on. A fixed seat stay should work fine. people have gotten creative when attaching the light if they have small bags under the seat and only when it is mounted on something moving all the time, are they disappointed. So, the long answer is yes, it should work.
No. If you mount it on a helmet or a backpack it will be moving in lots of directions. This will cause the light to illuminate irregularly and give off false-positive braking signals. It will also cause the battery to run out of juice more rapidly, which is why we recommend mounting only on a seat post.
Hold the light firmly in one hand and pull back the lever. Do not worry, you will not break it! As you pull it back, push the light up and the light will attach to the bracket with two definite clicks. Make sure you hear them, for a solid fit. When you detach the light from the bracket, pull back on the lever, push the light down firmly and it will come free.

I live in central Florida. I ride about four hours a day. Often in heavy rain. So far I have had no problems with the accelerometer!
Depending on its remaining battery power, it will take from 1 hour to three hours for 100% charge. We use a larger battery than 95% of all tail lights lights (1000 Ma) to give you maximum riding safety.
This feature is meant to save battery power when not in use. When your bike id motionless for 5 minutes or so, the light will go into a "sleep mode". It will blink slow and dim, thus using little power but making you aware it is still on. If you start moving within 45 minutes, the light will return to full function - same flash pattern as well. After about 45 minutes of inactivity, the light turns off completely. To restart, simply press the rubber button and it will come on to the same pattern you had before. The light has a sensor which also dims the light about 20% a night. Otherwise it would be too bright for approaching traffic.
