I think it will vary based on where you can mount the sending unit and the head unit. It is a low powered transmitter, so has to be pretty close. If you used silicone to attach magnet to one of the spokes, should be fine. Do your wheels have stickers on them? If so, can you get new stickers from the supplier? If yes to both, glue the magnet to the sticker and then replace the sticker if you ever have to sell the wheels / bike.
