Trying to help a buddy build a BMX inspired commuter bike. He wants something that will ride as much like his 20" as we can get but with a 1x setup to help with the hills. The only options I have found so far are the Black Market Contraband and NS Suburban but both use a axle mounted hanger which has already proven to difficult for him on his current bike so I'd like to avoid it if I can.

I'd also be open to 26" geared rigid bikes if they are more BMX then MTB.
