FAQs
Please read our FAQs page to find out more.
What age is this bike suitable for?
Each model is designed for a specific age range — from our Balance Bike (ages 3-6) to the ET-02 Ultra (ages 8+) and 350W 20" (ages 9+). Check the product specs for the recommended age group. Always ensure your child can comfortably reach the handlebars and touch the ground with both feet.
Is this bike safe for my child?
Safety is our top priority. Our kids bikes feature speed limiters, key-start ignition, disc brakes, and sturdy frames. Select models are UL-certified. We recommend always using a helmet and protective gear, and adult supervision for younger riders.
Can I limit the top speed?
Yes! Most DuoDian kids bikes offer multiple speed modes so parents can set a lower speed limit while children are learning. The ET-01 and ET-02 series also feature key-start ignition for additional parental control.
How long does the battery last?
Battery life varies by model, ranging from 5 miles (Balance Bike) to 15 miles (ET-01 MAX, ET-02 Ultra). Actual range depends on rider weight, terrain, and speed mode. Full charging takes 3-5 hours.
Does it come with a warranty?
Yes! All DuoDian kids bikes include a 2-year manufacturer warranty. We also offer a 90-day risk-free trial. If your child doesn't love it, return it for a full refund — no questions asked.
How much assembly is required?
Our bikes arrive 90% pre-assembled. Typical setup involves attaching the handlebars and pedals (if applicable), which takes about 15-20 minutes with the included tool kit and illustrated instructions.
