KEY FEATURES

RIDE MODES
Three different drive modes allow riders to learn the fundamentals of an electric balance bike at a lower speed, then boost performance as comfort and experience increase.
LONG MOTO-STYLE SEAT
The moto-style saddle allows for freedom of movement in varied riding situations while accommodating growth and riders of different sizes.
REGENERATIVE BRAKING
The K1D features a rear hydraulic brake with regenerative braking. Braking while riding the bike will transfer the kinetic energy back into the battery, thereby increasing the riding range.
INTUITIVE RED TWIST THROTTLE
K1D comes with a red twist throttle that clearly communicates control input to new riders.
REMOVABLE BATTERY
Extend their adventure! A convenient removable battery makes charging and swapping a breeze.
Confidence comes on two wheels
Unlock New Adventures
Built for ages 4-8, SUPER73’s first electric balance bike empowers your little ones to enter the two-wheel world with an emphasis on safe riding and self-assurance. Broaden their horizons and give them the confidence they need to tackle any adventure.
Peace of mind included with every ride
Safety First
We’ve anticipated every bump in the road with the K1D’s regenerative braking system, durable, puncture-resistant battery, and intuitive twist throttle. Whether you accidentally drop the battery or your mini-me fancies themselves an Evel Knievel, the K1D has you covered.
Paying homage to the young at heart
The Cool K1D
The K1D was designed to stand out. We combined the nostalgia of 80’s BMX styling with futuristic Hexagon patterns for a distinctly SUPER73 feel. But it’s not all curb appeal; a comfortable banana-style seat allows your child to grow with their bike while its platforms offer increased stability.
The K1D offers unparalleled performance
Regen for the New Gen
The K1D has a regenerative braking feature controlled by the throttle; when the throttle is released, the motor slows, recuperating kinetic energy. This energy is transferred back into the battery, which increases rider range. This range, paired with our longest-lasting battery, means unlimited playtime.

Getting your K1D up and running
THE FUN starts now
Each K1D initially comes in “Sleep Mode” to preserve battery life and will only work once activated; remove the battery and plug it into a charger so your family can get in on the fun ASAP! We recommend fully charging your kiddo’s new bike so that they can get the most out of their first ride.

Reviews
K1D, the kiddo loves it!
"Bike is great. My oldest was messing on it and the kickstand broke off. We tried to fix it but the plastic piece snapped. I went online to see if I could order a replacement, I do not see one for the K1D. Can someone help me with this?"
Great bike! Please bring these back!
"Great bike, my 4yo daughter loves it. Build quality is top notch, my only criticism is spare batteries don’t seem to be available and the bike is listed as discontinued. This is a great platform and there isn’t many options for kids’ e-bikes/e-motos, I’d love to see Super73 bring these back! That being said, it’s a great bike, if you can find one, buy it!"
Epic birthday/Christmas present. 4 year
"Epic birthday/Christmas present. 4 year old daughter loves it so do the parents."
Fragile Components
"Battery broke within the first week. Super73 says it will replace it. It has been two months. Fender also broke a few days after. Do not recommend."
You won’t be disappointed!!
"Our kids LOVE this bike. We’re grateful for the different speed settings so each child can ride at their own comfort level. It handles well in grass, gravel travel, and on the road. The battery life is great & it has held up well to crashes while learning throttle control. ;) I was skeptical because the price is much lower than others but it has far out performed my expectations!"
Would be 5 star but throttle control is zero
"The bike is awesome. Well built. Battery life is pretty good. The Only reason this isn’t a 5 star review is- there is zero throttle control. It’s not proportional, and therefore doesn’t teach a child to use a throttle effectively. It’s 0% or 100%. So keep that in mind if you want them to learn how to ease on a throttle. He’s adapted to bumping it on and off but I am legitimately unhappy with this throttle."
My Daughter LOVES her Super!
"My Daughter absolutely LOVES her Super73, she said she just wishes the battery lasted longer, LOL."
Cool Ride!
"Pretty awesome. My 5 year old loves it. It's a cool ride."
Fantastic, but not perfect.
"The bike is fantastic and my boys love it. Rating 4 stars because within 1-2wks of light riding from a 4yo, the plastic rear fender (right behind the foot rests) broke loose from the frame/tube. It’s a pretty poor design for a pretty necessary part, in my opinion. No other complaints so far."
Learned to ride!
"Very cool bike. My kid was not interested in riding bikes at all. We tried balance bikes and traditional bikes but he was not interested. Within a week he has learned how to balance and has been off and ripping since! I wish there was a battery indicator and a light option. Other than that solid product!"
