I just received one and matching controller, for the same possible end use!. It’s a serious looking thing with massive 24FET controller and the motor has steel gears in the gearbox. It’s about an inch longer than the standard cyclone 3000 and comes with a bottom bracket extension for 68mm. Cyclone-tw.com is great to deal with, email the guy first with your requirements and he’ll set up a custom PayPal link for each time. Shipping can be combined on request.
