Review on 🚲 Enhance Your Bike's Utility with Black Adjustable Bike Cargo Rear Racks - Retractable and Versatile Luggage Carrier Bracket for Mountain Bikes by Bill Lacy

I extended this pole all the way and it was too short. The extension is still under the seat when fully extended. I compared it to a Schwinn rack I had and the extension tube portion (slider) was over 3 inches shorter on a similar rack. I ended up discarding the shelf as unusable for my purpose. Electric bike battery inside. I didn't expect the pole to be so short. I understand why they make it so short (the weight rests on the seat tube), but I add stays to support the weight and minimize movement. The lack of length adjustment resulted in the bag being under the seat and inaccessible.
