Trikes/Bikes/Getting Around

Hi,

My daughter is five and has mild CP. She is a reluctant walker and can manage around 10 mins before getting tired - once tired, she struggles to walk and then trips up, scuffs her feet, becomes upset.
We’ve been managing this by pushing her around on a toddler trike. She is now too big for this though and she’s still at least a year away from being able to peddle a bike.
Can anyone recommend a company who make trikes for older children (we’d still need to push her though)?
