As above, Morzine or Les Gets plenty to do and you won’t really notice the bikes. Avoriaz is very quiet in the summer and really quite ugly. Its only an hour to Lake Geneva (eg medieval town on Yvoire) too for a day trip. Samoens town square is very pretty, good for an ice cream. Lac Joux Plan above Les Gets has stunning view of Mont Blanc on a clear day, take a picninc and walk 20-30 mins to Bourgeoise (start of mtb descent to Samoens). If you want an alternative you could consider around Lake Annecy, Grand Bornand/La Clusaz ?
Note Alps are much quieter in the summer than winter but that can be a plus.
Here is a photo from a cute local restaurant at Mont Caly above Les Gets. Pretty vilage and some simple family walking around there.
