I did this a while ago, but just figured it was worth a share.

If anyone has a broken, dirty or missing Ebrake handle cover a bicycle grip fits perfect, have to trim just a tad off the back end if i remember correctly.

They are cheap, and there are thousands of different designs and colors to choose from.

And being its made for a bicycle they are pretty durable as well!

Slips right on, have to use a little spit, or other lubricant of your choosing to slide on but no glue or screws or anything else required to hold on. Nice and snug, hasnt slipped since i put it on Jan 2016.
