Dual motors inside wide balloon wheels, a foldable aluminum frame, swappable batteries, and three control methods make B1 impressively capable. Its rugged, modular design feels purpose-built for soft sand rather than adapted from an ordinary wagon.

Reusable batteries, an optional solar panel, replaceable components, and honest production-risk disclosures are encouraging. More detail about material sourcing, repairability, and end-of-life recycling would strengthen the sustainability story.

The B1 Standard Kit is HK$4,702, while the non-powered version starts at HK$2,347 and specialized bundles begin around HK$6,508. It is a substantial purchase, but the electric drive system, modular accessories, and heavy-hauling capability help justify the premium.
