Inner tubes

[flhtci2006]

I have 2 bikes on order and want to be prepared in advance.  The RadRunner plus has 20x 3.3 tires and the Rad Rover Step thru has 26 x 4.  What size range of tubes fit these tires?  Is there a preferred tube?

Morning,

Here is the recommended replacements at Rad. https://bit.ly/30yHkhW

They are sold out of a lot of things but I would imagine you can use the information to search for another vendor but might find the same since the entire bike industry has seen astronomical increases in buying. I was shocked at Walmart the other day when I want to the bike department and their hung rows of bike racks were virtually empty unless you were looking for that first bike with training wheels HA!

Thank you for the info.  Looking at various online places, seats, tubes, etc are all on backorder.

For these not as standard tire sizes, especially with the new RadWagon 4 I highly recommend everyone stocking up on 2-4 tubes to make sure that you're never without a replacement. Nothing is worse than having a beautiful day and not being able to ride due to not having bike tire tubes.
