For those of you that has or currently have experimented with single speed conversions, please share your thoughts with me. I'm looking for ideal (and safe) setting for my son. Chainring 42T. What's a good teeth count for him?

Background story, my 13 yr old and his friends got busted riding their surrons on streets and got a hefty fine for Mom and dad. Mom locked his surron down to be used for track days only.

I bought a bafang mtb for him so he can ride without being bothered by cops much, but I want to make the operation and feel to be like a electric dirt bike.

No hill climbing. Mostly flat terrain like parking lots. Lot of wheelies and now he can hit bmx pump tracks.

Thanks.
