Mongoose LilGoose 12

A great bike that your little one will love.

The bike comes equipped with all the essential mechanical & cosmetic features. The bike has training wheels that are height adjustable so that you can raise the height of the training wheels as her confidence builds.

It has a chainguard to protect clothing and legs.

A mudguard to prevent getting too dirty when she rides straight through those muddy puddles.

The seat post & handlebars can both be adjusted to fit your child perfectly as they grow. It also comes with rear coaster brakes which make pedalling & stopping easier for the little ones.

Last but not least, the frame is aluminium, which means it’s lightweight and easy to manoeuvre.

All in all, Mongoose know how to make a great kids bike and the Lilgoose is no exception.
