We run them through a 12-point stability test before any batch leaves—frame load, handlebar torque, wheel alignment, all checked against CE cert we hold, and we retest if anything shifts by more than 2%.
The steel frame (it's 1.2mm wall thickness, not the thin stuff you see on some budget models) holds up well, and the PP saddle is actually impact-tested at 15kg for 500 cycles—basically simulates a 6-year-old bouncing on it for a few years.

Batch consistency is pretty tight because we keep the same mold suppiler for the PP parts, but we do a random 3% retest on every production run, and if any sample fails we pull the whole batch for re-inspection.

4kg net weight means it's light enough for a 2-year-old to steer without tipping, but teh 12-inch EVA wheels (or air-filled if you prefer) give decent grip on pavement—just don't expect it to handle gravel, it's really a sidewalk cruiser.
Lead time is about 30 days or so for a standdard 4pcs/ctn order, but we usually have stock for 200-300 units ready to go if you need a quicker fill.
We ship in cases of 4 pieces per carton, so the MOQ is 4 units. For larger orders, we can discuss volume pricing.
Yes, the 9594B is CE certified as listed. We can share the certificate with your order confirmation.
Absolutely. We offer both wheel options on the 9594B — EVA for lighter weight and no maintenance, or air-filled for a smoother ride. Just let your sales rep know your preference.
Typically 15-20 days for a standard order after confirmation. If you need it faster, we can check stock levels.
The handle is adjustable, but the PP plastic saddle itself is fixed at the standard height for ages 2-6. The steel frame design keeps the ride stable for that age range.
