Hey everyone, I recently got my Nimbus Impulse 36er (love it :D) and now I want to get a relatively cheap wired cycle computer. I have no clue how to set it up/install one. If someone could give me a kind of step by step on how to do so it would be greatly appreciated.
Thanks. 
You set it up just like on the front wheel of a bike.
Check this thread for an idea of what kind of value to enter for wheel size.
Try to find one that can take size settings big enough for a 36" wheel - quite a few of them don’t. If you end up with one that doesn’t go big enough, you’ll need two magnets on the spokes (and set the size to half what it should be), so make sure you get a spare magnet in that case.
