I have the same problem with my Currie scooter. Actually my kids have the problem after driving for 20-30 minutes in the grass (I won't allow the 8 year old on the road, even with a headgear). My soluction? I'm installing one of our Neodynium rotor motors with high current MOSFET's. It is a nice coincidence that our motors are a drop in replacement for the Currie!. Your option? stick a fan cooled heatsink on the side of the Currie motor with good gap filler material to make up for the imperfections between the heatsink and motor. Rod Now you say this because your motors are so expensive or unobtainable or you aren't sure that they will work. I would like a report if your experiment works and you might get a few customers.
