Most of my buyers are tired of paying for lithium they don't actually need—the 24V 12AH lead acid battery on this TEW108LA(E) keeps the price down, and it's usually enough for a 6km/h top speed with about 18km range per charge, though expect a bit less if you're on inclines.

It's 42kg with the battery, so not lightweight, but the steel frame folds down to 745×370×730mm which fits most car trunks without issue. The dual 250W motors give it an 8° climbing ability, and the electromagnetic brake system is actually pretty responsive—we've tested it on a 45cm seat width unit and it holds well on slopes.

Front wheels are 8-inch solid, rear are 12-inch pneumatic (or solid if you prefer), and the padded nylon upholstery holds up better than cheap vinyl in my experience. You can flip up the armrests and swing away the footrests for transfers, which most buyers find easier than messing with detachable parts.

Anyway, the 45cm seat depth and 39.5cm backrest height are standerd for most adults up to 100kg—anything taller and you'll want to check the fit before ordering. One thing nobody asks but matters: lead acid battery takes about 6-8 hours to charge fully (form flat), so plan for overnight charging.

We do custom colors on the upholstery for MOQs of 50 units or so, and teh swing-away footrests can be swapped for ones on request—just specify at order. CE, FDA, and ISO13485 certs are current, but I'd confirm lead time if you need the COA within 2 weeks; we usually have stock, but not always.

It's better than most steel-frame folders in this price range for the climbing ability alone—8° isn't a hill, but it handles curbs better than the 6° models. Not suited for heavy off-road use though, those solid front tires will bounce on gravel.
It supports up to 100kg, so it's suitable for most adults. Just keep that limit in mind for safe operation.
It's CE, FDA, and ISO13485 certified. We can share copies of those certificates upon request.
You get about 18km range per charge with the 24V 12AH lead acid battery. That's under typical conditions.
Yes, the footrests are swing-away, so you can push them aside to get in and out of the chair more easily.
Lead time is usually 30-45 days, and the minimum order quantity is 50 units per shipment. We can discuss flexibility for trial orders.
