When a newly bought uni wheel spins reluctantly ......it is worth to asses tightness of the bearing brackets. I bought new Uniqo trick bike. The rear wheel felt quite tight. The thing is pretty sensitive to wobble when front and back wheel(uni) are RELATIVELY disengaged. When I finally relised bearing brackets and have made them finger tight the back wheel spins freerly and I wobble minimally while riding it in disegaged mode.🙂
