It is the conversion kit for people who want an e-bike, not a project: one front wheel swap, two batteries strapped where bottles would go, two connectors clicked together — twenty minutes, no frame damage, fully reversible. And because it is 250W with pedal assist at 15.5 mph, it is completely UK road-legal from the first ride. No settings. No paperwork. No grey areas.
The 2026 upgrade rewrites its one old weakness: range. Twin LG-cell packs (7Ah + 15Ah, 22Ah total) now carry it 40–60 miles between charges — three times the original — while the new 4A charger halves the wait. All-in weight, both batteries included: 6.0 kg. Plenty of rival kits weigh more before a battery is even fitted.
