Thank you
Thank you , i highly recommend buying a bike from early trailz. I bought a bike thinking it was for kids and I miss read the information. I realised a mother later after delivery and was worried I was going to be stuck with a bike to big for my daughter. I emailed e trailz and they have contacted me...
