What makes a classic speedometer great is its simplicity. It doesn’t require power to show your speed, there are no complicated screens to navigate or batteries to charge or replace. It’s always “on” and ready to go. When you want to know how fast you are going, look down and there is your speed. That makes it the most reliable of all of the speedometers. Some of the better models feature an odometer as well.

The drawback to a mechanical speedometer is that the installation can be difficult. It does require removing the front wheel and attaching hardware to the hub. If you are comfortable with DIY bike repair and you’re mechanically inclined, you should be able to have it installed in under 30 minutes.

Aside from the more difficult installation, another important consideration is the size of the wheel the speedometer is rated for and the size of the wheel on your bike. Installing it on a wheel larger or smaller than it is rated for can result in an inaccurate reading.

Unfortunately, a dial speedometer is the most inaccurate of all bicycle speedometers. The faster you ride, the greater the inaccuracy. Overall they generally provide an acceptable reading, usually off by only a couple of miles per hour if at all. If you are looking for a simple and reliable speedometer, where accuracy, bells, and whistles don’t matter, this may be the best speedometer for you.

Digital Speedometers and Bike Computers

If you are looking for a highly accurate and feature rich speedometer solution, a bike computer may in your future.

Prices range from 10 dollars to hundreds of dollars all based off of brand names, screen type and size and capabilities of the unit.
