I would do that if we had the bike, but it's in transit (previous owner told me the tire was flat). I'm hoping to get a tube to throw in the bike when it arrives so we can get our little guy started asap

Hi all - We just picked up one of the 12.5" models for our 3 year old after months (and months and months) of searching for a gently used bike. The rear tire is flat and needs a new tube, I know Oset sells 'em on their site, but I was hoping to get one at a local bike shop and not wait for shipping. That said, I don't know what tube to get - there are multiple widths available...12.5 x 1.75, 12.5 x 2.25, 12.5 x 2.5...etc. I know the rim width is 2.4"...not sure which tube to get. Thanks in advance for any help
