Had itchy bumps for a week now after going biking w/ sunscreen. Seem to be clear/flesh colored until I scratch them and they turn red. Is it heat rash?

In brief: Not likely
It is likely the sunscreen had an ingredient that when exposed to sun caused a reaction called "photo sensitivity".

In brief: Maybe
It is possible, depending on location of the bumps/rash.
Areas under clothing or heavy perspiration are potential sites for such rashes. If on outside skin areas where sunscreen was applied, may be assoicated with contact allergy to the sun lotion or its preservatives contained. Do not scratch them. You may try use of 1% hydrocortizone cream (cortaid) applied 2-3 times a day... No scratching.
