Hi! Super interested in this awesome gadget. So, you would have to buy two M232, so that you could have one for each wheel correct? How long would the batteries usually last if imagine being run continuously? Also, won't the cable get wrangled up in the wheel? Thx! :).

Firebox says: Hi Rúben, you would have to buy one for each wheel yes. The cable shouldn't get wrangled up as if you put in the middle of the wheel it will just revolve through the center of the mechanics...
On the suppliers website they say that with 3AA batteries the light should last for around 20 hours. Hope this helps! :)
