We’ve had 3 different e-bikes for 5-8yr kids… the Hiboy is by far the best. Plenty of speed, it’s rugged, and has the best battery life by far. My son rides it all the time. Perfect for honing skills prior to stepping up to a gasser.

After 4 months of watching my son (4 years old) on the Hiboy DK1, I can confirm that this is a GREAT first dirt bike for a kid his size! While there are cheaper electric dirt bikes on the market, this was the most affordable one I could find with a variable speed throttle. Right now my son and I are working on strengthening his throttle control, which means he’s practicing on “speed 3” to help him break the habit of just “gunning it” all the time. So far, I’m pleased with how the bike’s holding up!

I have it and it works perfectly for me. Maybe it doesn’t work perfectly for you because you’re almost fully grown. It’s for eight-year-olds and five-year-olds.

Yeah when I drive those I got those but my dad sell them now he got a motorbike but the throttle on that electric bike is terrible and you can slide your hand on it
