Best budget bike rear-view cameras

Top pick: the Wscoficey rear view camera — the cheapest one that's still a real rear-view setup: a 1080p camera feeding a 4.3" handlebar screen, with a 5000mAh battery so it runs for long rides without a power bank. If you just want to see behind you on the cheap, start here.

Who the others suit:

• COSITTE 1080P with 4.3" monitor — a small step up in polish if you'd rather buy a named-brand kit.
• Zootealy handlebar mirror camera — best if you want the screen to double as a mirror.
• Sharper Image Rearview Bicycle Camera — the most finished, most expensive option; pick it for build quality over value.
• Unbranded dual-lens dash cam — cheapest of all, but it's a front-and-rear recorder, so treat it as a dash cam rather than a live rear view.

All are handlebar-mounted and need charging; none is a plug-and-play mirror.
