48V Ping - Brushless Wilderness Tests

11/16/2008 - 1st Long Ride (~5miles): Stable, smooth performance. About 23-24mph on flats. Very quiet. Some cogging at startup, but soon goes away. Some vibration up the steepest hills without pedaling. Pedal-first controller is smooth and kicks in about 3mph or less. May opt for the "shunt mod" in the future to double the current (40A). Bike uses a shimano internal hub shifter, which is a great match to the hub motor: very easy shifting. Highest gear is just barely acceptable for pedal assist on the flats & downhill.

Ping - Brushed Kollmorgen Tests

IMG_4452.jpg
10/11/2008: 3rd test ride: Farther. Went on a 5 mile loop. Very windy, long rolling hills for the most part. I adjusted the pedaling gears so that I could contribute from about 15mph-22mph. Everything went very smooth. This thing is really fast! Scary fast!
