Like the bike and don’t regret the purchase. For me, the shifters do lack significantly and lack smooth and reliable gear switches. I upgraded to this from a 5 year old 500 dollar bike and the shifters are essentially the same quality. Other than that, love everything about th
e bike, the form is comfortable but the seat sucks. Very fast and sleek and good geometry.

This bike is great value for money. The front brakes rubbed a bit initially but once they were seated it is now running smoothly.

Suite à ma première sortie mon pneu arrière ne se gonflait plus. Le service après-vente a été excellent et ont changé mon pneu. J'ai un autre rendez-vous car le dérailleur n'est pas parfait. Je monte des pentes abruptes et il "saute". J'espère que le problème pourra être réglé
