The Perfect First Bike to Learn, Grow & Have Fun
The Mongoose Lilgoose is made for kids aged from 2 years old who are ready for their first big adventure on two wheels.
With built-in training wheels and easy-to-use features, it’s the perfect bike to build balance, confidence, and a love of riding.
Safe, Stable & Easy to Ride
The Lilgoose is built on a lightweight aluminium frame with a tough steel fork. The combination makes it easy for little riders to handle.
And the Lilgoose stays strong and durable as they learn.
It's also got coaster brakes (pedal backwards to stop). So it’s a simple and natural action for toddlers to control their speed and stop safely.
Designed with Kids (and Parents) in Mind
Every detail of the Lilgoose is made to keep young riders comfortable and secure:
- Training wheels add stability as your child learns to balance.
- Enclosed chainguard protects clothes and little fingers.
- Rear mudguard helps keep them clean when splashing through puddles.
- Adjustable seatpost and handlebars grow with your child for long-term value.
Ready to Ride, Right Out of the Box
It has bonus extras like a mudguard, chainguard, and bell.
The Mongoose Lilgoose is fully equipped and ready to hit the footpath.
And it comes full assembled by our team of experienced mechanics.
