We just started to do recreational rides as a family. I pull 6yo on a "trailer bike" which makes me almost as slow as my wife
I got Motobecane Elite Adventure and my wife got Motobecane Latte disc. Her bike is faster, but we doing OK riding together.
Problem we have is with my 11yo daughter. She rides bike that was given to us(Diamondback). Fit is good, just right size. I tuned it, all works nice and smooth. However she can't keep up with us. One thing is she have "mountain" tires and another thing - brakes is not very good. I wouldn't mind doing something about this but don't wan't to buy bike she will overgrow in 2 years. Will changing tires improve her speed? It's 24 inch tires. Or it's just kid not being able to keep up?
She does good on flats but hills is really bad.
