Very happy with bike , 3 day uk delivery , tracking worked fine, bike needs front wheel attaching, tyres pumping up, front caliper needed adjusting , nothing unexpected, bike comes with tool kit, pump, comprehensive manual, bike exactly as listing.

Seller highly recommend, had couple of questions that were answered straight away, great bike at great price ! 👍 😃 , very well packaged
