Variants of this model differ. LVNENG publishes TWO LX04 builds side by side and they are not interchangeable. LX04 (the figures recorded above): 1.44 kW BOSCH motor, 1×48V26Ah Greenway portable lithium pack, 5 h charge. LX04-SE: a 2.05 kW motor and a 1×60V23.4Ah pack — a different system voltage, so chargers and spare packs do NOT cross between the two, which matters enormously in a mixed used lot. Both are quoted at the same 45 km/h, 217 kg max load, 12°(23%) gradeability, 1700×700×1050 mm, 1230 mm wheelbase, 80/100-10" tubeless tyres, front and rear disc brakes, and EEC L1e-B / Euro 5 homologation. The 45 km/h figure is the L1e-B regulatory ceiling, not a hardware limit, so non-EU units may be set differently. Separately, the designation 'S6' given in the brief could NOT be confirmed: LVNENG's own model list contains S8, S9 and S70 in its lead-acid range but no S6 anywhere, so treat 'LX04 = S6' as an unverified reseller equivalence and confirm against the frame plate. Because the range figure appears to be quoted for two packs while the battery row specifies one, establish pack count per unit before assuming 50 km.
