Sharper Image Rearview Bicycle Camera vs MT80 Dual Lens Dash Cam

Buy the Sharper Image rearview camera if you want a simple, wireless-free rear view with a bright 4.3-inch handlebar screen and a camera that survives rain. The unbranded MT80 dual-lens dash cam records both directions and loops footage to a micro-SD card, which suits riders who want evidence after an incident. The Sharper Image has the better build and waterproofing (IP68 vs IP65) and a larger screen; the MT80 adds front recording and loop recording but its 720p front and 480p rear video is soft, and it needs 12-24V wiring and a memory card.

• Choose the Sharper Image if you mainly want to see traffic behind you on a bright handlebar monitor and ride in rain.
• Choose the MT80 if you want front and rear recording saved to a card for later review.
