Sportique is THE best scooter shop in Denver.
The owner, Colin, told me that it is his mission in life to please scooterists. I took my 50cc Vespa to Sportique to get it upgraded to 70cc. Colin took great care of me. Sportique got the parts ordered and installed quickly, communicated well to keep me updated on the status of the job, and the scooter is awesome now that the kit is installed. Everyone I talked to there (Colin, the parts guy, a couple of sales guys, and the mechanic who did the work) were all super friendly and more than happy to answer all of my questions.
Colin lives up to his word that it is his mission in life to please scooterists. I'd highly recommend going to Sportique for all of your scootering needs. Sportique is Awesome!
