Frequently Asked Questions (FAQs)

1. Can you put a 5 year old in a bike seat?

Front or Rear Mounted Kids Bike Seat Rear child bike seats are generally larger and can often accommodate kids up to 5 or 6 years old! If you start with a front-mounted seat, you'll eventually need to transition to a rear-mounted seat to fit your growing toddler.

2. What age do child bike seats go up to?

Most child seats are suitable for children between the ages of about nine months and four years. The lower limit is dependent on the ability of your child to sit up unsupported – that is, on the floor rather than propped up with cushions.

3. Are child seats on bikes safe?

Baby bike seats are the only safe way to carry a child on your bike; the American Academy of Pediatrics advises that front packs, backpacks, slings and carriers don't offer adequate protection. It also isn't a good idea to go out for a ride during nap time.

4. How do you carry an older child on a bike?

Front seat, rear seat, and Followme Tandem is an option, or two seats and a trailer. Try a longtail Cargobike with two back seats and a tag-along if the older child insists on pedalling too.
