Wired bike computers
Not long ago, wired cycling computers greatly outnumbered wireless ones. Due to great advances in wireless data transmission, this ratio has almost reversed today. Wired cycling computers now mostly represent the lower end of the market. However, these computers can still impress those who want something simple and lightweight. Instead of a wireless sensor, on these computers, you'll find a purely mechanical transmitter on the fork that doesn't require an additional energy source to send the signal from the spoke magnet.
