Oh, I was just having a related conversation here .
The bobike mini looks cute, I've not used it before. Is the child in front of the handlebars?
I'm a fan of the centric safe haven. Costs about £60, new. It goes on the front, on the crossbar, but it has a harness and so on. It's only meant to be good from a year, but I'm sure it'd be fine for an 11-month-old.
I'd recommend the rhode gear seats for the rear of your bike, very safe,ds1 dropped my bike with ds2 in his seat and he was fine, easy to use and comfy for baby. Used mine since ds was 6 months, still using it every day at 2 yrs.Even tried to buy another recently to keep at grannies.
