This is a hugely significant difference between a WeeRide and rear-mounted seats.
Because the child falls asleep between your arms, on the balance of the bike you can continue riding safely - not usually the case with a rear-mounted seat.
This means you can go for day trips and not worry about the journey home when the little one will be asleep within 5 mins!
