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.

Ride with the best

Customer reviews
— 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.

Great bike, worth the money

Originally wanted to buy their first version last year but bought this one the moment it came out since my son was desperate to learn to ride already. Very happy with the decision. Very high quality, looks professional, and my youngest will be able to use it next summer when its time so I dont need to buy another. Love the extension system which I didnt see on other bikes would recommend.

Great investment

Teaching my daughter how to balance FIRST was the way to go! She had enough confidence to skip those loud and uneven training wheels and set off on her own. This 3-in-1 bike is a great investment, especially if you have multiple children who will benefit from this bike’s versatility.

We love our Xtend 3-1 bike ...

We purchased this bike through Walmart.com in April 2020 and my daughter absolutely loves it and it is a great bike. I love the sturdy tires, it all great quality and the frame extension is cool. I am only disappointed that it went from being $100 to $250, I understand that we got a great deal but maybe go up $50, But adding on $150 was just too much, so we won’t be purchasing one for our 4 yr old now. So review of bike is that it really is a well made, super intelligently designed bike but not for $250.
