I’ve used A couple of other GPS speedometers , and this one so far is the most accurate, even more accurate than the Google GPS map that comes with the phone , and you get a variety of different colors to choose from and you can use it vertically or horizontally , The format is easy to understand and the settings are easy to use , and believe me whether you ride regular Bicycle or an E bike , it’s a good addition it makes your bike look cool , people who saw it didn’t even know it was my phone they thought it was the actual speedometer that comes with the bike , Believe me this will save you money if you go Buy a speedmeter , like this out there they’re overpriced too complicated to use and most of them don’t even work on 20 inch fat tire bikes , this is perfect 😊
