Velorbis Mobii Cargo Bike Maintenance
 

So I bought this bike on Craigslist a couple years ago.

Cycle-chic with Mobii - the ultimate bike for mums - Babyology

The steering is getting a little sloppy and I can't remove the stem to see whats going on in the headset (not sure if that's what you'd call it).

Anyone work on these? Is there a trick to removing the collar at the top of the headset? Anyone have a repair manual for these bikes?

I emailed Velorbis a few times and got no response.

Maybe post some clear, well lit, close up photos of the headset and stem.
