"Reasonable" ?
Reasonable is what my lone scooter/motorcycle shop wanted. $40 if I bring in the wheel & new tire. They don't balance scooter tires (nor does the closest actual "scooter shop", 45 miles distant.)
Hourly shop rate was $108 per hour.
Put scooter on lift, pull front wheel, dismount the tire, remount the new tire, install wheel on scooter....probably close to 1 hour shop time.
Save a lot of $ by blocking up your scooter - unbolting axle and taking you wheel in to the shop.
