Bicycle Speedometer & Wireless Odometer for Bicycle Cycle Bike Computer with LCD Display & Multi-Functions

Solid speedometer. I had the sensor just a little off and it was not working correctly. Moved it up a bit and has been great since.

I tried attaching this so many different ways but the design is very flawed. You have to have the magnet SO close to the sensor it basically has to touch. Not sure what bikes this works on, I even tried attaching something to the back of the sensor so it would be closer to the magnet but it still wouldn’t work. Very frustrating! I wish I had returned.

PROS:Inexpensive especially when on sale.Similar to some Cateye models.Easy to install.Accurate if you know what you're doing and understand how to tweek things.Well built.This version is wireless. (Wired version only uses one battery.)2 batteries included. (Rechargeable versions available.)Comes with double-sided tape and zip ties.Menu is easy to use and understand.Any option in the menu you can think of is available.Backlight (4 secs or all the time)CONS:Microscopic font used in instructions.Because of the wireless unit, getting it to lineup with the magnet on my specific mountain bike takes some finagling.Generic box doesn't look good for gift giving.I've owned some very expensive cyclometers over the decades and although you can get better ones then this, for the price you can't beat it.

Great tool for a bike, and at a really good price. I admit I had some doubts, but was pleasantly surprised at how accurate this device is.

Should be build with straps on it

Mounted on E bike

Low quality . Stopped working after 100 miles, troubleshooting did nothing , look somewhere else

The screen is a good size, not too big or small. Numbers are easy to read but not accurate at all. The modes are funky. I would suggest keeping the back off where the battery goes because you'll need to reset it if you skip a mode.Just not worth the hassle. I'll be returning it.
