Vivinavi

車載用サイクルキャリア（リアマウント・2台用）

・ Body, manual

Purchased at outdoor store REI in July 2019 for $ 160. It has some age-related wear and tear, but is perfectly usable. I switched to a hitch carrier type when I recently replaced my car and no longer need it.

It can hold 2 bicycles and after working on it a few times and getting used to it, you can attach and remove the carrier in 2-3 minutes.
*The time required to mount bicycles is not included.

In our family we used it on our sedan （ e.g. ： Corolla ） and SUV （ e.g. ： CR-V ） depending on the occasion. I did not leave it installed, I put it on just before use and removed it as soon as I was done.
*The disadvantage of this type is that the trunk or rear gate cannot be opened or closed while in use.
