Heartway Monster X S12 Heavy-Duty All-Terrain Mobility Scooter
Description
Heartway Monster X S12 Heavy-Duty Mobility Scooter
Heartway's Monster X is a 350 lb (160 kg) capacity, full-suspension 4-wheel scooter built for gravel, uneven pavement and outdoor trails rather than shopping-centre aisles.
A 900W 4-pole motor and independent front and rear suspension are paired with oversized 15 in rear and 13 in front pneumatic tyres, and independent retailer listings for this model state a driving range of roughly 25-45 km depending on conditions, close to this store's own stated 40 km figure.

Suspension front and rear, not just big tyres
Independent front and rear suspension absorbs shocks from bumps and uneven terrain on top of the traction from 15 x 6.3 in rear and 13 x 4.8 in front pneumatic tyres, aimed at riders who need more stability than a standard recreational scooter provides.

Frequently asked questions
How far will it go on a charge?
This listing states up to 40 km per charge; an independent Canadian retailer's listing for the same model cites a range of 25-45 km depending on wind, rider weight, terrain and speed - treat 40 km as a mid-range planning figure rather than a guarantee.
What terrain is it built for?
Full front and rear suspension plus oversized pneumatic tyres are aimed at gravel, park trails and uneven pavement, not just smooth indoor floors.
What's the weight capacity?
350 lb (160 kg), confirmed both by this listing and an independent Canadian mobility retailer's listing for the same Heartway S12 Monster X model.
