This morning, Bea and I took the Brompton for a spin. As you can see, the iBert seat sits a bit lower than usual compared to its position on a full-sized bike. Yesterday, I thought that issue would be a problem but its really not. I was able to pedal quite normally.
As usual, whether on a full-sized bike or a folding bike, Bea enjoyed her bike ride with Daddy. Look at the smile on her face. It's priceless!
Now for the bad news. After I uninstalled the iBert seat, I discovered that the clamp of the stinger left a deep scratch on my head tube / stem. And this is after I put black rubber foam padding around the tube precisely to protect the head tube / stem from these kind of things. Imagine what the damage would be if I attached the metal clamp bare and without padding. The abrasion would be bigger and deeper.
Argh!
I touched it up with white nail polish. It didn't erase the scratch, but at least its not that noticeable.
I guess that's it for the iBert-Brompton combination. It's back to the Trek Allant for this child seat. I don't want to further damage the head tube / stem of my Brommie.
If you don't mind paint chipping off your folding bike, then go ahead and install the iBert seat. I think the head tube / stem can carry the load. And you can pedal normally.
