The replacement brushes are only like $10.
If you shop around online you can find a deal. My understanding is that the brushed motor provides more torque and not as much speed but the range is reduced. But for a five mile commute it probably won't matter. Putting this setup on a road bike fork you need to be careful and not break the fork with the torque the motor provides. You also need 10 mm spacing on the fork and most newer bikes are 9mm. I only engage the motor once up to speed which also lengthen the usable distance.

When you look for these kits check the controller and batteries. Some come with a 36 amp controller and 12v 7amh batteries. Some kits have 50 amp and 12v 12amh batterries which means more speed and more range.
