The 80100 that you posted SkyHobby wanted $106 for, versus $122 at Leaders. HobbyKing was cheapest, but since there's no sign mine will ever come, it's worth a few bucks more if someone else will just SEND IT.
Just looking that this I impulsively ordered an $8 motor that's more powerful than any of the heavy metal motors in my current scooters, I'm sure replacements for them are all around $70-80. Plus a $12 RC controller. Let's see how this does on a bike.
