BikeBac Under Rack Case

Built a case for Bikebac theft/loss tracker for my daughter's e-bike - normally the bikebac attaches discretely to the water bottle carrier but her bike didn't have one. Instead, her bike had a bike rack similar to those found on Amazon (they seem to be sold under various brands). The construction of the racks is highly variable, so the lid may or may not fit (i installed without as the tracker is well secured without it). Secured using 4x Hex M4x16 bolts and 4x M4x8x6 heatset inserts for plastic (94459A170).
