Recently, we went to one of the steepest hills around to test the new BMC 600 watt, internally geared brushless hub motors. There are two versions, a "torque" (the V2-T) and a "speed" (the V2-S). We wanted to see how they did for steep hill climbing on an Xtracycle equipped bike, and did some head-to-head rides with them. Note that Morgan is the heavier rider by about 40 lbs, so we did multiple tests by swapping bikes back and forth to get to the heart of the question, "which motor is best for climbing?"

So cool!

I have a BMC V2-S, but it's mounted on the front 20" wheel of a LWB recumbent, which makes it more torquey. I use 48v. It basically erases hills! You can cruise up them at 25 mph, or a bit slower if you don't pedal. Amazing motor. Hasn't stalled yet.
Great video. Post some more.
