Delta Cycle and Home& Universal Bike H lebar Bar End Mirror, Fully Adjustable H lebar Rearview Mirror For Bicycles, Large Ultra-Clear Glass Safety Mirror fits Road, Mountain, Cruisers, E-Bikes

It's easy to install in the handle bar end. No tool needed. Good for the price of $4.99. I'm buying another one for the other side of the handlebar.

installed worm style hose clamp around base of ball socket, this reactified the problem. delta design should correct this problem ! gary
