Bottom line

OTTOLOCK’s SIDEKICK is a low-cost keyed U-lock available in two sizes: regular and XL. OTTOLOCK provides three keys. The security of this lock isn’t third-party tested. Owners praise the easy-to-use locking mechanism, low weight, and protective silicone coating. The regular version’s compact size is convenient for carrying, but the opening may not fit over thicker poles or bike racks. The XL provides additional length and a wider opening. Owners and testers deem the lightweight SIDEKICK a user-friendly option for quick stops or use in low-risk areas, but its effectiveness as a standalone lock in high-risk areas is questionable.
