Hi do the straps velcro on like could this strap onto a mountain buggy?

Hi Kim, we have a review on our website from someone that says “I have this mounted on an old Mountain Buggy Urban. Fits perfectly”. If you are unsure though you are welcome to trial one at your local Baby On The Move. Here are our store locations here: https://www.babyonthemove.co.nz/store-locations/. Hope that helps
