ADO folding eBikes: storage, weight and riding features
Battery configuration: Air 20 Ultra uses a 36V 9.6Ah Samsung battery. Air 20 Pro and Carbon Pro use 37V 10Ah Samsung batteries. All three offer NFC power-on and ADO app ride recording with riding statistics; built-in GPS tracking is a separate Carbon Pro feature.
Rack accessories: Choose accessories for the exact rack and mounting system. MIK compatibility alone does not establish child-seat suitability or mean accessories are included; observe both rack and bike load limits.
Storage and lifting: Ultra and Pro figures follow their official ADO specifications. Their net weights exclude rear rack and mudguards; Carbon Pro's quoted weight includes them, so these are not like-for-like equipped weights. Battery inclusion is not specified. Folded sizes are not packaging dimensions; no battery-removed weights are stated. Leave clearance around the folded bike and consider a folding and lifting demonstration.
Range: Maximum assisted figures are not guaranteed. Rider and cargo weight, assistance level, terrain, wind and tyre pressure affect actual range. Optional range-extender batteries are not included in the standard-range comparison.
Ask Sun Chaser which ADO folding model suits your storage, commute and accessory needs.
