Hi all quick question is it ok to put a rear babyseat on a carbon boardman roadbike would the carbon be sturdy enough.
Thanks

I think the quick answer would be definitely not, the seat will put stresses on areas of the frame not built to take that sort of load. I would guess it would be a quick route to damaging your frame.

I heard a horror story in the bike shop when I was getting my bike of someone bring back a carbon frame they had clamped the child seat to the cross bar. Luckily the frame had failed when the child wasn't in it.

Dont do it.

Carbon seat tubes are often shimmed internally with a metal tube. This makes them stronger than top tubes. Also, different direction of force.

I wouldn't recommend it but it might be OK if done carefully.

Thanks for the advice everyone as annoying as she can be I kinda like my little girl. Gonna keep her around for a while. No child seat on the roadbike it is.

Unsure what this would do with carbon but it does avoid clamping and crushing the carbon.


If there are eyelets for mudguards on the rear you could possibly get a rear rack which attaches to the eyelets and on the top get a seat collar that has an extra bit on the back to take a rack. Then there is a baby seat that mounts straight onto the rear rack.

The problem I see with this is the additional weight issue not being supported through the seattube, you are also putting weight through parts of the frame just designed to hold mudguards in place. When my two year old is on the back of my tricross there is a huge difference in the weight and general balance of the bike. It's genuinely a completely different feeling bike which takes more care to cycle.

'Carbon' bikes are made from carbon fibre reinforced composites, not egg shells :pac:

How about a front mounted seat - I have one like at WeeRide.ie.
I doesn't put weight on the handlebar stem and only some on the seat post area. To be honest I am not sure where the weight goes. It is not clamped onto any part of the bike. And the balance is much better as the child is close to the bikes centre of gravity. And you can talk to the child.
