In my experience stores buying for that 3-6 age group usually start with the 12-inch since it's easier for smaller kids to mount, but we actually see more gyms and daycares going for the 14-inch because of that it lasts an extra year or so before they outgrow it.

Frame's carbon steel, so it takes a beating, and the whole thing—handlebar and seat—adjusts without tools which matters when you're fitting five different kids in one afternoon. Load capasity's about 20-50kg, roughly 44 to 110 pounds, so most kids under 8 are fine. Wheels are either EVA or rubber depending on your cost point and rims are just plastic (not the best for rocks but fine for pavement or grass).


We've done batches with custom logo and color, MOQ is usually 50 units or so, and the PU foam seat is pretty basic but actually holds up better than the padded ones for outdoor use. It's not great for serious off-road trails though—teh plastic rims won't handle that long-term, just so you're aware. 40kg kid on a 14-inch feels stable, but 50kg gets close to the limit.

Anyway, lead time is roughly 20 days after deposit, and we ship one per carton with bubble wrap so no scuffed frames. COA and CE certs are standdard.
We typically require a MOQ of 500 units per model, but we can discuss smaller trial orders if needed.
Lead time is about 30-45 days from order confirmation, depending on the quantity and customization requirements.
Yes, we include the CE certificate with every shipment to confirm compliance with safety standards.
Yes, the seat is adjustable to fit kids from ages 3 to 8, with a height range that accommodates inseams from about 35 cm to 50 cm.
Each bike comes in a single carton, fully assembled except for the handlebars, which require simple attachment.
