Converting a kids' bike requires extreme caution — low power, speed limiters, and safety-first design. Here's what we recommend (and what to avoid).
Let's start with an honest disclaimer: converting a kids' bike to electric is controversial. Many e-bike experts advise against it entirely. Kids don't have the reaction time, physical strength, or judgment to handle motorized speeds safely. That said, there are legitimate use cases — kids with disabilities who can't keep up with family rides, rural families with long driveways, or teenagers who need transportation.
If you're going to convert a kids' bike, the rules are very different from adult conversions. Power must be minimal (250W maximum), speed must be limited (12-15mph maximum), and the kit must include brake cutoff sensors. This guide covers the safest approach to kids' bike conversion.

Final Thoughts
If you decide to convert a kids' bike, do it with extreme caution. Limit power to 250W, limit speed to 12mph, install brake cutoffs, and supervise all riding. For most families, buying a purpose-built kids' e-bike with integrated safety features is a better choice than DIY conversion.
