[QUOTE="12- carbon, post: 43794, member: 2397"] [USER=56]@John Conroy[/USER] The motor is [URL]https://www.astroflight.com/3220-astro-brushless-motor-details.html[/URL] In my application the motor can see about 10,500rpm motor speed. Input into the planetary gear set, gets the output shaft of the planetary reduced to 1/6th which then feeds into a chain drive that reduces a further 1/6th. I dont see a problem with a small drill hole in the end of the shaft. My timeline is sooner the better :cool: but I'm happy and grateful to wait patiently for any help I can get. A shop with full of motorcycle parts sounds like the right kind of shop! This toy is my "motorcycle" now that I have kids and need life insurance lol. [USER=3]@Janger[/USER] It's for a electric downhill bike. I had it mated to a very impressive cycloidal drive initially.
