Inspired by children, built for parents

Learn to ride

Teach your kids to ride the smarT way by simply adding pedals to the balance bike they are already familiar and comfortable with. The added confidence gained from learning to pedal on a bike they can already ride makes the leap-of-faith towards independent pedaling much easier on children.

Seamless modularity

The innovative design of the Xtend Mg+ means that you get three products for the price of one. Start your kids off with a fun sturdy balance bike, when they are ready add pedals and teach them to ride, and finally extend their bike and let it grow with them.


For a bike to grow with a child, it needs to last with a child. We built the Xtend Mg+ out of the highest quality materials so that you can hand it down from child to child as your kids get older, allowing the whole family to enjoy their bike for years.

— My Grandson loved it! He's in another state so I had it delivered to them which was super convenient. I compared about 10 different balance bikes but this one made the most sense since it grows with my little guy. Very happy overall.
— Laura W. Love Smart Trike! We bought one of the trikes for my sons 1st birthday he is now 3 and we still use it almost daily, so when it came to his first bike, i loved the look of the Smart trike xtend, another quality product that would grow with him and last years, their customer service and sales teams are fantastic, it came really fast and wasnt too hard to assemble. My only suggestion would be i couldnt see a helmet to match on the site for availability in the UK so had to purchase else where.

My opinion, don't use stabilizers!

I see a lot of parents here asking about stabilizers. I taught my 3 children to ride a bike, and I never used stabilizers. They're just counter-productive. They don't teach children how to balance, they make the bike less agile, they only teach kids bad cycling habits, they can't be used on uneven ground in addition to being ugly and noisy. Stabiliser graduates still have to learn the primary skill – balancing – with a sudden transition from being supported to unsupported, which can result in wobbles, crashes and loss of confidence. Don't use them, don't need them.
