Why can't a child bike seat be mounted on a carbon frame? I have bought a BoBike junior bike seat for the rear of my bike which is a Cargo bike but the seat instruction says it can’t be mounted on carbon frames, baffles me as to why?
Carbon tubes tend to be very strong at withstanding forces in the direction they are designed for, but weak at resisting other forces (such as clamping forces compressing the tube), hence why bolts for carbon bars, seat posts etc are usually only torqued to 4-5Nm.
