Motion response and synchronisation. TÜV Rheinland-commissioned indoor testing covered walking and transition scenarios. Published test notes report up to 64.9% faster response, CMC above 0.90 and as high as 0.99, plus average assistance-phase synchronisation of 97.5%. Fit, gait, terrain, settings and environment can change results.
Cycling exertion. SGS testing at 60 ± 5 rpm and 100 W resistance recorded an average heart-rate reduction of 42.68% across the tested participants. Results depend on intensity, terrain, fit, physical condition and use.
Walking runtime. The 30 km / 7.5-hour figure was measured at 4 km/h on a Grade 2 incline, with Eco Mode at 30% power, through continuous movement to battery depletion. Real routes, loads and users will vary.
Cycling runtime. The 1.7-hour Hyper Mode result came from continuous indoor cycling at 20 km/h and 100% power. Environmental conditions, bicycle, load, terrain and riding style affect practical performance.
Materials and protection. X Max S construction includes aluminium-alloy hip tubes, stainless-steel hip levers and carbon-fibre reinforced leg levers. IP54 performance was measured under controlled conditions and may reduce with wear.
General limitation. Manufacturer performance figures were collected in laboratory conditions. Experience can differ with firmware, environment, fitting and use.
