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. May opt to up the "front ring" of the bike for higher gearing...

Development Background: Bought bike from Craigslist. Came with 400W BL-36 and no battery. Wanted to go to 48V, and quickly found out that the controller was only rated at 50V (50V caps). Bought C7220PF controller from ebikes.ca. Bought Ping 48V 16Ah V2 battery on ebay...

Forks are welded aluminum, appear very strong, but still wanted a torque arm for safety. Ampedbikes seems to have a killer product...
