Hello folks, I need some advice


I recently aquired an Apollo Commuter bike with the intention of putting a nexus IGH hub in it.
It was only once I got the bike home that I discovered it has 650b wheels and not conventional 26" as was advertised.

Whilst I know 650b bikes are growing in popularity, the simple fact is that finding decent-priced 650b rims and tyres in Australia is damn near impossible, and im trying to stick to a tight budget on this build

My question is this: has anyone successfully swapped out 650b wheels for 26"? the bike has side-pull brakes and by my measurement using long-drop bmx calipers I should have no brake problems

Or go 650A's for a near perfect fit. Performance tires are sometimes hard to find.

650B are 26" tires. Just one of the 5 or so versions of 26" tires.
Maybe going to a 650A (590mm) would simplify things?

Not sure what you mean, but I found this to differentiate the two: https://www.bikerumor.com/2012/06/06/...reakdown-more/

Velocity makes the Synergy in 650B and are Australian if I'm not mistaken.

Good idea, I just did some quick measurements thanks to info from Sheldon Brown and that looks like it will work well. just ordered some rims and tyres in 26 1 3/8

I'll let you all know how it works out
