I just finished installing a rear Crystalyte 408 Hub motor on a stretch cruiser frame. When the wheel is on the bike with no load (just on the kickstand) the wheel goes around smooth with no vibration. When I sit on the bike and take off, I feel vibration in the handle bars and seat until I reach higher speeds, then it goes away. I understand that these motors will vibrate the bike some, I have a 5303, and 5304, and they vibrate a tiny bit on start up, but nothing like this. Is there a problem with my controller or hub motor? Or is this behavior normal?
Thanks Guys! :)
