Q: I have the single bike 1upusa rack and wanted to add three single rack attachments so I can carry a total of 4 bikes. Technically, this is against 1upUSA recommendations. To carry 4 bikes they advise needing to use the double rack plus 2 add ons to carry a total of 4 bikes. If my bikes are fairly light, am I safe carrying 4 bikes using the single rack and three add ons? They say you should only have 2 places where the racks are joined by bolts, not 3. Thoughts? -Guest
A: Hi, I was wondering the same thing and wanted to see if you ever gave it a try. My plan was to start with the super duty single (2" only reciever) and make it for 4 bikes. My bikes are all under 30lbs and the 4th bike would be my daughters Micro BMX (17lbs).
