We looked at your RFQ for a bulk baby stroller order and I think the GD-KB-S001 fits what you're after pretty well — it's the model that most buyers go with for newborns up to about 3 years, and the five-point safety system is pretty much standdard at this point for any serious suppiler, it's not something you'd want to skip on.

The adjustable seat is nice for older toddlers who want to sit up more, and honestly the 340mm width is comparable to what you'd find on mid-range units at retail — it's not the widest but it's fine for most kids, the seat height is 580mm which is higher than some cheaper models and that matters for getting them in and out without bending too much.

Bulk pricing kicks in at around 50 units, which you'll want to check on because we usually have stock but confirm lead time — it's about 20 days or so for that quantity, MOQ is typically 10 units for a first run but (if you're doing a standard SKD 85% setup) the lead time could shrink a bit.
One concern buyers always raise is weight, 10.9kg net, which is not the lightest on the market but that aluminun rim matrial and teh 10.5-inch wheels are what make it stable and smooth on uneven ground — you don't want something too light if you're using it on pavement or grass, trust me.

Also the carton size is 520x230x760mm per unit, which is easy to handle for shipping, and it folds down small enough — about 85% SKD — that you could probably fit more on a pallet than some inflatable models we've seen, though the gross weight at 12.4kg means shipping cost isn't negligible.
Our standard MOQ is 100 units per model, but we can discuss smaller trial orders if you're just starting out. Just reach out and we'll see what works.
Yes, we include the CE certificate and a test report for each batch. Just let us know when you place the order, and we'll prepare the docs.
The seat height is fixed at 580mm from the ground, which is ideal for most dining tables and easy parent access. The backrest reclines, though, so the baby can lie flat.
It ships in a single carton, size 520*230*760mm, with the stroller folded 85% SKD. That means you'll just need to attach the wheels and canopy on arrival.
We can customize the rim material or wheel size for larger orders. The standard is aluminum rims with 10.5-inch wheels, but we're open to your specs.
