Stopwatch Assembly Instrument Display Accessories Compatible With Segway Ninebot Gokart Kit/Gokart Pro/Gokart Lamborghini Electric Kart

Works perfectly as a digital display. The numbers are large, bright, and easy to read even in daylight. Simple to install and very reliable — exactly what I needed for timing and monitoring.

This synchronized with my Segway Ninebot Pro go kart instantly. It is very easy to set up and it never fails to sync or work. It automatically turns off when you turn the go kart off. You do have to turn it on when you start. The only complaint that I have is that you cannot switch this to mph. I understand that the rest of the world outside of the U.S. and U.K. uses Kmph so I'm not going to dock a star for that, but it would have been nice to have.

Works great, no issues. 4 stars because no MPH. This device connects with ease each time the gokart is turned on.

Given that this device did not come with instructions of any kind, I thought it was going to take research and trial and error to get it to pair and function properly... not so. I did not even have to pair the unit using the white pairing button adjacent to the battery compartment. I powered on both the Ninebot and the device and they auto-paired. Really a useful feature to be able to switch driving mode without disconnecting the speaker, pairing the phone, making the change, disconnecting the phone, reconnecting the speaker... you get the idea. With this just bring the kart to a stop, then adjust be pressing down on the red toggle button. The speedometer is in Km/h and there is no option to switch to Mph. I am from the USA, so I would have liked to have had the option for Mph; however, it is useful to be able to make quick conversions from imperial (which basically no one but the US and Australia use) to metric (which the rest of the world quite sensibly prefers). So I don't view it as a point against it because it will indirectly provide a benefit. Great little accessory.

This stopwatch assembly is perfect for my Segway Ninebot Gokart. Easy to install, clear display, and really helps monitor lap times and performance. Makes racing more precise and fun! 🏎️
