Rear-rack load counts within the bike’s carrying capacity. Observe the bike, rack and accessory limits. Rack capacity alone does not establish child-seat suitability. Confirm any unspecified limit before loading.
These are stated pedal-assist figures, not guaranteed or directly comparable test results. Rider and cargo weight, assistance level, terrain, wind and tyre pressure affect actual range.
One Ultra’s 140km figure requires the optional second battery; its standard-battery figure is up to 100km.
