Real‑world range example

Sur‑Ron LBX, aggressive off‑road riding pushing it to the limits, 100 kg rider, bike fully modified and fully loaded with all the upgrades like bigger wheels, extensions, etc - weighting 67kg and set to push 25 kW with 650 phase amps ( with upgraded motor) ≈ 80 km / 50 miles 
*Range varies with rider mass, terrain, gearing and throttle habits (but realistically it's 50-70miles)

• 55 Ah – about 70‑80 % more range, longer peak‑power window (recommended)
