Re: what did you do to your motorized bicycle today?
You know what would be nice?
A good, heavy duty wheel with bearing races shaped to accept a high quality, sealed bearing.
Those cage bearings are kinda delicate.
Also, maybe when I get some tacky grease I'll try just lining that race with balls and leave the cage out of it. Of course, I'll probably just get into trouble. But I'm fairly adventurous. Maybe I'll give it a try.
