    Seeking opinions about rear rack connections

    I am building a rear rack for a Townie Electra with a front wheel electric assist ( link to original build ). I have already broken two bought aluminum racks due to the 22 lb battery, so I am brazing a steel one together.


    The problem is the connection to the seat stay. The original frame boss on the right side has pulled out due to the weight on the rack.



    I am thinking of 'wrapping' this part of the frame with an aluminum band/clamp, and bolt it to a support beam from the rack. I am also thinking of adding to additional support from the rack to the seat stays below the brakes with P-clips.

    .

    I am concerned about the hole left from the pulled out boss on the seat stay. Should I try to fill it with epoxy or wrap it with fiberglass, or just leave it alone? Any comments about the planned supports or their placement?

    Thanks for your time.

    the hole isn't doing anything, I wouldn't worry much about it

    I would make the rack closer to the wheel
