Velo 7

Good speedometer for the money. Screen can appear distorted with polarized glasses. This is my second from this company. Good products

works great, easy to install and set up

Some folks say it's hard to set up, I found it quite easy. While I really wanted a wireless, I was concerned about interference from my many lights and stray signals in my suburban area.
Only con is no back light, but battery will last longer.

I have had a Velo 7 for years and just bought another one for a different bike. This is a simple odometer, speedometer, and clock that gives me all the information I need on my bike rides - very easy to set up, install, and use.

This is a great device to track time riding, distance & speed. I’ve had others that were too complicated to use.
