Great replacement for my Tao Tao Hellcat 125. I used stock wiring for speedo to the wheel and did a plug swap and it works great. Bright and colorful.NOTE: You’re going to have to calibrate the speedometer to your bike by inputting a three digit code. I’ll save you the headache... someone posted a 21†front wheel is at a 016. I’m at a 12†wheel and I put an input of 045. Gps confirmed accuracy within 1 mph with that input.

Several issues with this product.Installed on a GY6 80cc moped Grom cloneRPM bar jumps up to 13000 then back down when engine is reved up.Clock goes off 3 minutes per day, at the end of the week you need to adjust the clock.2 months into using it. The whole display flashes on and off. Have tried various ways to reset the unit with no success.Horrible quality. Cannot return the unit as the return window closes a month after purchase.

For the price, this thing is fine. The calibration for speed made no sense to me. I put it on a bike with a 21 inch front rim, and I ended up putting in a calibration value of 016. I had to use a GPS to find a baseline, and then did some ratio math to figure out about what the value should be. Now that it is dialed in it works great.. Also, even though it went on a machine that once had a tachometer on it, the wire that fed the tachometer from the bike did not work. I had to tie into the trigger coil to get RPM indication. Before I started connecting, I used a 12 volt battery to identify all of the lights before I soldered it up. This helped me to know where everything was going to connect. The neutral light, and all of the gear lights are reverse polarity, meaning the wire you are connecting for the neutral light is really going to ground. On my bike the neutral switch connects the neutral wire that goes to the light to ground. It worked out great for that. The wiring diagrams that came with it were fairly accurate. Just one wire was a different color than what was indicated. Also, it did not have a wire in any way for temperature. It was simply not present in the wiring harness. Also, I never did get the fuel indicator to stop blinking empty. I used the appropriate resistance values on that wire to fool it into thinking it had a full tank, but no luck. I just put up with it flashing. Now that it is all working, I am mostly happy with it.

You need to figure out the wheel perimeter and set the cylinder number according to the manual, I had problem on how to switch kph to mph, Jenny answered my question timely and kindly. Five stars..

This thing was NOT a super straightforward install or configuration but overall I am very happy with the accuracy and the functionality of it.I had to:-switch pins for 3rd and 4th gear-switch the connector for my current speedometer-do math to calculate the tire circumference in cm and set the # of magnets to 4After doing those things, I tested the accuracy of the speedo and it is within 1 mph of accuracy at 25 mph.I like the background color selection and the fact I actually have a digital clock on this bike now.If you're comfortable with moving pins if needed and doing the math you need to get accurate speeds, then you will be happy with this product.

Nothing about this accurate. Impossible to get it to work. Not worth the money. Directions are horrible. The colors listed dont match. The descriptions for each wire they have make zero sense. They need someone that actually speaks English and is from America to make new directions. On top of that I didn't even receive everything listed. I would give zero stars if I could.

Very easy to install following the instruction, If wires were longer ,that would be better.

Saving 100 dollars from buying something else is nice especially when it works without a problem. You may have to repin for your specific harness like I did but it's not hard. The settings are there so you can change how many wires for fuel sensor, how many magnets for the rotor, tire diameter. It reads accurate can't complain.
