BEBEROAD T4 vs bicystar fold: two small cabins, two different limits
Both are one-hand folds for a small dog. The useful difference is the weight number you can trust and the height of the wall the dog leans on.

Weight limit
The bicystar Amazon title and the YX-D01B support guide both say 35 pounds. A marketing block on the brand store also says 45. We use 35.
The T4 brand sheet says 44 pounds and the Amazon details table says 30. We use 30. On the number PawRank will stand behind, the bicystar is the higher limit, 35 against 30, even though the T4's brand claim sounds bigger.
Cabin
T4 basket: 22 × 12.5 × 9.84 inches. bicystar carrier: 22 × 12 × 8.3 inches. Length is a tie. The T4 is half an inch wider and about an inch and a half taller at the wall.
Neither wall is a sitting room for a leggy small dog. The bicystar page mentions an opening up to about 19.3 inches with the top open. That is not a fixed roof, so we do not score it as 19 inches of cabin.
Fold, weight, and evidence
The bicystar is 17.4 pounds and folds with the wheels on, to about 23.6 × 20.5 × 10.8 inches. The T4 is about 16.5 pounds. Both are a one-person trunk load. The T4 carrier does not detach. The bicystar is also a fixed stroller, not a carrier you unclip.
Ratings on November 10, 2026: T4 beige 4.4 from 29, bicystar 4.5 from 24 on each color page. That is a draw. Both colors of the bicystar were in stock. T4 beige was in stock and black was low.
How we call it
bicystar YX-D01B is the call on this page. For a dog between 30 and 35 pounds, the bicystar is the one whose limit we will actually use. For a dog under 25 pounds who wants the taller wall, buy the T4, or look at the Pet Gear Lite, which publishes 17 inches of height and a longer review history.
Which one holds two cats?
Only if both cats are small, the combined weight is under the limit we use, and they accept a 12 inch width. Neither stroller is a side-by-side double.
Which fold is smaller?
The bicystar's published fold is the flatter package. The T4's brand tables swap which side is the long one, so measure the folded T4 before you promise it a shelf.
