MotoTec has an interesting one, too. I thought about getting the MotoTec but decided not to. They both have a hub motor. IMO, a hub motor is fine for an e-bike (I have 3) but I wouldn't want one on a minibike. A geared hub motor has planetary gears inside the housing/hub so you're stuck with the gearing whether it's ideal for your use or not. I also question whether the motor is powerful enough, Greenworks is 1000 watts (converts to 1.34 HP), MotoTec is 1500 watts (converts to 2.01 HP). I've looked at 72 volt, 3000 watt, 6000 RPM conversion kits on Amazon that are around $300. They are chain-drive kits so you would have gearing options. They come with a T8F (metric) sprocket so would require adapting a #35 or #41/420 sprocket. The big expense would be a good battery, a 72 volt battery with enough capacity to be worth using would cost at least twice as much as the conversion kit, I'd want at least 40Ah on a large bike (MotoTec's 60v is 20Ah, Greenworks' two 60v are 16Ah total). You can use a lower voltage (as low as 48v) battery with the kit to use a less expensive battery but that wouldn't make sense, IMO, I'd want the full power output. You could use a lower capacity 72v battery, say 20Ah, to lower cost at the expense of range. I'm thinking one of the kits installed on a little Coleman CT100U would be fun and I just happen to have a couple of those sitting around... 3000 watts converts to 4.02 HP, doesn't seem like much but electric motors make a lot of torque from 0 RPM.
