We're shiping these in mixed color batches of about 12 units per pallet, 155×82×76cm each, so plan your floor space accordingly—lead time is usually 20 working days or so, but we've had some orders come through in 15 when the factory isn't slammed.
You get a 350W motor pushing 70kg of fiberglass and steel at up to 20km/h, which is pretty much ideal for a standerd bumper car ring—the lithium batteries (two 12V50A units) give you 4-6 hours runtime, though we've noticed heavier usage in peak hours tends to eat into that closer to 4.

It's not for toddlers—minimum age is 8+ years, and teh radar warning system actually works well enough that we've had fewer collision claims than with the old mechancial bumpers, but the auto-stop can be a bit abrupt if someone's driving aggressively.

Remote control is included, so you can override form the sidelines, which most operators appreciate for crowd control, but the music system is pretty basic—basically a preloaded MP3 player that you'll want to swap out for your own playlist after a week.

core components for 12 months, though the fiberglass body is tough enough that we've only had one replacement claim in the last 200 units or so—just be aware the LED strips are considered wear items and not covered.
Anyway, you'll get the bumper cars with COAs for the batteries, a remote, and a charging cable—no assembly required beyond bolting on bumper guards, which takes maybe 20 minutes per unit.
We typically require a minimum order of 10 units for first-time orders, but we can discuss smaller trial orders depending on your location and shipping logistics.
Lead time is usually 15-20 working days after order confirmation and deposit, though it might vary based on current production volume.
Yes, we can supply CE, RoHS, and FCC certifications upon request, along with a warranty certificate for the 12-month coverage on core components.
Absolutely, we offer mixed colors as standard, and we can do custom color matching or logo printing if you order at least 20 units.
Store them in a dry, cool place away from direct sunlight, and keep the batteries at about 50% charge if you're not using them for more than a month.
