Epic Long-Distance AdventurerRelative to Current E-Motion range
HELIX identifies safety & visibility as the strongest suitability profile, followed by comfort and confidence.
HELIX estimates each bike’s relative performance using consistent engineering principles and the best verified specifications available. Results are modelled comparative estimates rather than laboratory-certified measurements. Actual performance varies with configuration, rider, battery condition, terrain, weather and tyre settings. Acceleration: modelled 0–25 km/h on level ground. Electric-Only Range*: minimum pedalling only to keep assistance active, with no meaningful rider propulsion. Hill Climb*: modelled 60-second climb at 10 km/h.

Why This Bike?

Who is the Mamba Savannah best for?
It suits riders wanting an easy-access, step-through commuter with an upright, confidence-focused ride. HELIX positions it for everyday travel, practical errands and routes where strong hill assistance matters.
Why is the Savannah a strong choice for hills?
HELIX estimates a 24.6% hill-climb capability and records 85Nm of peak torque. Those figures indicate strong low-speed assistance, although actual climbing depends on rider weight, gradient, surface, gearing and battery charge.
What Electric-Only Range* should I plan for?
Use the HELIX estimate of about 68km as a planning guide, not a guarantee. Range changes with assist level, hills, rider and cargo weight, tyre pressure, temperature and stop-start riding.
Is the Savannah easy to get on and comfortable to ride?
Yes. Its step-through frame reduces the height you need to lift your leg over, while the balanced posture supports relaxed everyday riding. The governed rider-height guide is approximately 162–187cm; a test ride remains the best fit check.
What supports confident everyday control?
Hydraulic disc brakes, stable 26-inch wheels, an aluminium step-through frame and practical visibility equipment support predictable daily use. The rear rack and fenders also make the bike better prepared for commuting and errands.
Is this Savannah configuration eligible for NSW public-road use?
The governed E-Motion record treats this 250W constant-rated configuration as NSW public-road eligible when pedal assistance is limited to 25km/h. Confirm that the selected bike has not been modified or switched to a non-compliant mode.
