Nellvita Wireless Bike Computer, 27 Multi-Functions, Water Resistant Bicycle Speedometer, Cycling Odometer with Extra Large LCD Display, Cycle User A/B Function, Can Wake Up Automatically

The system is very easy to install on bike, Im using it on a Stumpjumper bike with 29" wheels and calibration was simple enough. The computer is up and running fine, there are a comprehensive amount of functions which is very nice for low priced product like this. The issue I had encountered is that while in use, if sweat, even a small drop falls on the screen, it lock the computer up to a point none of the functions work. Even if you wipe the small drop off and dry the computer it is still locked and unusable. I understand product is not liquid resistant nor that is the expectation, however if by mistake a sweat falls on it, you will lose usability on the computer for the rest of your ride. =(

Evaluation of the Nellvita YT-318 Bicycle Computer Recieved 20 Feb 20191. This bicycle computer allows for configuration of two sets of wheel sizes for bicycle A and bicycle B, however the package comes with mounting and transmitting hardware for only one bicycle. In order to use this computer on a second bicycle, the mounting hardware and transmitter would have to be removed from bicycle A and reinstalled on bicycle B.2. The mounting bracket I received with my unit, designed to attach to the bike with zip ties, lacked a tab for releasing the computer. The instructions provided show a tab for removal of the computer from the bracket, however the bracket I received did not have the release tab and therefore, once the computer is engaged in the bracket, it will be impossible to remove once the bracket is mounted to a bicycle. The same applies if the battery in the computer needs be replaced. The computer cannot be removed from the mounting bracket, therefore the bracket would have to be removed from the bike to gain access to the battery, requiring new ties and remounting the device to the bicycle again.3. Because the limitations of the mounting/release mechanism, I designed my own using velcro, shown in the pictures.l4. Once I input the initial settings on the computer, things went well. The setup is a bit involved but once everything is input things work well. I had to read over the settings and adjustments a number of times to learn how to reset things like the speed, trip meter, travel time but once learned things work smoothly.5. The output has so many readings and is actually more complicated than needs to be, but overall I am happy with the product, only disappointed in the mounting setup as it is seriously lacking. I also don't know why anyone would need a tire RPM for. I sure don't. With my limited use at the time of writing this review, I give this product a solid four stars. However, if the mounting and release were modified to be functional then I would give five stars.6. This is just my initial evaluation of this device with only a few miles since installation. All works well so far and I'll provide an update once I put it to more use. I like that the readout is large, starts immediately once motion is detected and it's easy to reset. I don't like the mounting design or the flimsy zip ties included. With a better mounting and release design, this would easily rate a four star rating.

I had originally written a fairly scathing one-star review for this product. My original concern was that one of the two units I purchased stopped working almost immediately, and the other quit after a few weeks.I was disappointed because other than the total failure of these units, I really liked the feature set and the display. I discovered that the batteries that came with the unit were nearly dead, and replacing them with fresh name-brand batteries helped. For a while.I'll spare you the details, but after a little more than a year of use, both of my units quit working. The display still comes on, but the touch controls are no longer working on either one. New batteries didn't fix them this time.This is a shame, since these computers deliver a very useful feature set with a nice, easy to read display.

A few things you should know about this unit. Good display, easy to setup. But it is not labeled Nellvita, it is really a Bogeer yt-318. Mine was labeled Bogeer. Also mine the censor had to be within about 4inches from the display to read. I tried it a few ways with known good batteries. Each time I started close the display where it was reading and started moving down the fork or away from the display and it would loose signal about the 4 inch mark. At first I thought I might be all the steel in the big front fork blocking the signal. I then tried it horizontally to the display no steel in the way. Again it would get to about 4inches and drop out. I did return the unit. I will be using a hard wired unit moving away from wireless.

I was really excited to get this bike computer. However, the instructions were severely lacking making it somewhat frustrating to set up. After I got it installed and programmed, I took my bike out to try it and the computer was not registering anything. I tried putting the computer in 3 different places on the bike and none worked. It came with an extra battery so I switched out the battery in the transmitter and it started working. It had come with a dead battery. I was about to return it because I thought the distance on my bike to the transmitter was too far. I am glad I gave it one last try. I have not used it enough to comment on the functions or durability.
