For the best match, check both the phone size and the handlebar diameter before choosing an offer. The case also uses a touch window rather than open access, so the way you plan to use the phone matters.

Confirm that your phone is under 6.4 inches and that your handlebar diameter falls between 18 and 32 mm. If you need fingerprint unlocking through the cover, this model does not state that it supports it. The stated bag size and extra storage space should also be checked against what you plan to carry.
