so, i am pretty new to the moped game. i bought a puch maxi in july and have been riding it around ever since. the other day i had the misfortune of getting to my moped after work and finding a flat front tire. for those of you in boston, is there a place to buy tubes? or do these things just take a heavy duty tube, like a mountain bike tube? i would imagine not, but if anyone has any suggestions please let me know.
