橋 5 It’s perfect for two motorized bikes in one regular bike. No space problems no jittery problems. Wheels fit perfectly without any interference from the motorized wheel In the rack position.But this one problem the manual in the section where I have the photo is too dark how am I supposed to understand even the reading it included how about how this part is supposed to go in please in the future fix this problem. It’s annoying I truly recommend this product other than the problem with the manual photo. Have a nice day
