As an update
Bought a weeride, and its going straight back.
fitted it on my turner flux and couldnt even get on the bike, impossible. Maybe my frame too small?
Also the small thumb screw that attaches the seat to the bar?? really thats the only thing attaching your little one to the bike??
i spoke to weeride before buying and said my little one was approaching the 15kg weight limit, and they said it would be fine, and that limit is only set by the EU as other front seats attach to the handle bars? even at 14kgs the seat felt flimsy and really didnt ave much confidence in the single screw attachment. The foot rests also fouled my steering hitting my forks.
There is no way this seat does ages 1-4 years, very disappointing. back to the drawing board. thin Ill look at trailers or tag-alongs
