Why not replace everything at the same time? A complete wheel set in 24” is plainly the in-between size when switching from a child’s bike to a youth bike. 24” wheels are the ideal size to be converted to a mountain bike. A front wheel in the 24” category offers an enormously comfortable ride and a large range of applications from mountain bikes, trekking bikes, city bikes, recumbent bikes and also bike trailers. A dynamo, a hub gear with or without coaster brakes, a roller brake, or an anti-lock disc brake can be built on and with this comes an adjustment period which is almost not needed with this diameter.
