Using the SmarTrike STR5 is a breeze. When your child is around 9 months old, you can use it as a stroller. As they grow, you can transform it into a trike. Steering is easy with one hand. To assemble, no tools are needed - just a few clicks and you're good to go. You can control or let your child take the reins with a simple button push. Remember, keep the trike away from sharp objects to avoid damaging the 3 - tier canopy. Also, regularly check the front wheel shock absorbers for any signs of wear. Clean the trike with a damp cloth. Enjoy safe and smooth rides with your little one!
