Using the SmarTrike STR3 is a breeze. For the stroller mode, simply unfold it with a few clicks as it's tool-free. Attach your baby who is at least 10 months old securely. You can easily steer it with one hand. When your child is ready for the independent trike mode, switch it with a push of a button. Regarding safety, always make sure your child is strapped in properly. The stroller has safety certification, but you should still be vigilant. For maintenance, wipe it down regularly with a damp cloth. Avoid using harsh chemicals. If the front wheel shock absorbers seem to need attention, you can check the manufacturer's website for further guidance. Enjoy many happy rides with your little one!
