Description
The Fortress S425 mobility scooter is Sunrise Medical Canada's compact outdoor 4-wheel scooter. Westin Healthcare sells it and delivers it for homes in Brampton and the Greater Toronto Area. It is a current S-series Fortress, not the older 1700-DT.
Sunrise rates the S425 at 330 lb (150 kg), 12 km/h (7.5 mph), and 258 lb (117 kg) including batteries. The S-Series brochure puts two 55 Ah Group 22NF batteries and 12 in (30 cm) pneumatic tyres on the chassis. The 2019 Scooter Matrix prints a 78 in turning radius. The CA spec table's 119 in figure looks mislabeled; we use the matrix.
Who this scooter is for
This scooter is for a person who wants a 4 wheel mobility scooter for mixed indoor and outdoor use, stays at or under 330 lb, and wants more speed and tyre than the S410. Families usually call us when a 1700-DT leftover is no longer the right factory order, or when a travel scooter feels too small outdoors.
If you want the tightest current Fortress turn, start with the Fortress S410. If you want 15 km/h and 13 in tyres, see the Fortress S700. If we still have a mid-size 1700-DT in the shop, that page is the Fortress 1700-DT 4-wheel.
- 12 km/h (7.5 mph) and a 330 lb rating
- 12 in pneumatic tyres and all-round independent suspension
- Two 55 Ah Group 22NF batteries
Range, speed, and batteries
The Fortress S425 has a top speed of 12 km/h (7.5 mph). Sunrise does not print a kilometre range on the CA card or the S-Series brochure. The 55 Ah pack is the maker's "longer journeys" story. We do not invent a km figure. Range on any scooter shortens with rider weight, hills, cold, and aging batteries.
Charge with the charger Sunrise supplies. Ask us about charge time from the S-Series owner's manual when we write the order. Keep the batteries off a concrete floor in winter. Do not run them flat.
Portability and transport
The Fortress S425 weighs 258 lb (117 kg) including batteries. That is a mid-size outdoor scooter, not a suitcase scooter. Sunrise does not print a heaviest-piece weight for a take-apart. Westin delivers and assembles it. Do not plan to lift it into a car by yourself.
This is not an airline scooter. Group 22NF lead-acid batteries are not a cabin lithium pack. For a folding travel scooter we stock, see the Solax Transformer.
Fortress S425 specifications
These figures are from Sunrise Medical Canada's S425 card, the S-Series brochure, and Scooter Matrix 628749-CAN Rev.1. The specification tab holds the stored values. When the CA card's 119 in turning radius fights the matrix 78 in, we use 78 in.
Weight capacity 330 lb (150 kg). Top speed 12 km/h (7.5 mph). Weight including batteries 258 lb (117 kg). Width 26 in. Length 53 in. Turning radius 78 in (matrix). Seat 19 in wide, 18-20 in deep on the matrix; CA card also prints a 20.6 in seat height. Wheels 12 in (30 cm) pneumatic. Batteries two 55 Ah Group 22NF. All-round independent suspension. Front and rear LED lighting. Luxury seat with height, depth, and recline, plus flip-up arms and seat rotation. Brochure colours: Urban Grey or Red. Large wire basket standard.
Warranty on the April 2021 S425/S700 matrix: 3 years on the main frame weldment and the tiller, 2 years on the controller, motor, transaxle, and charger, 1 year on shrouds, seat, tires, and lights. Wear items sit outside that term.
S425, S410, or S700
The S425 is the compact outdoor Fortress: 12 km/h, 12 in tyres, 330 lb, 78 in turn. The S410 is the everyday 4-wheel with a 58.2 in turn, 10 in tyres, and a 34 km printed range. The S700 is the 15 km/h, 13 in, 350 lb outdoor step-up. The 1700-DT 4-wheel is leftover stock, no longer available to order from Sunrise.
Funding help for a mobility scooter in Ontario
Ontario's Assistive Devices Program (ADP) can fund 75% of the cost of a mobility scooter when the need is long-term and the scooter is prescribed through an assessment by an ADP-registered occupational therapist or physiotherapist, and some income-support programs cover the full cost. Not every scooter qualifies, so talk to us before you buy. March of Dimes Canada, Veterans Affairs Canada (VAC), and community programs can also help. Westin Healthcare's staff work with these programs every week and will point you to the right route for your situation. Visit our funding page or call (905) 451-7743 to talk it through.
Delivery and setup in Brampton and the GTA
Westin's own team delivers and sets up the Fortress S425 across Brampton and the Greater Toronto Area. We bring it in, assemble it, and show you the tiller, charger, and freewheel lever before we leave.
We have three stores in the Brampton and Toronto area if you would rather see a 4-wheel outdoor scooter first. For a scheduled in-home setup, call (905) 451-7743 and we will book the next date that works. Same-day delivery is offered through our hospital bed rental service; purchased scooters are delivered and set up on a scheduled date.
This mobility scooter is oversized. The Canada-wide free ground-shipping offer on smaller goods does not apply. If the scooter is going outside the GTA, ask us for a freight quote. Inside Toronto and the GTA, White-Glove Delivery (bring-in, unwrap, test, take packaging away) is described on the shipping policy. Any charge is confirmed on your order.

Service and warranty
When something on the scooter needs work, you call the shop that set it up, not a distant parts desk. Westin Healthcare has a service and repairs department. Our technicians come to the home or workplace.
Sunrise Medical Fortress warranty
The April 2021 S425/S700 matrix for the original purchaser is 3 years on the main frame weldment and the tiller, 2 years on the controller, motor, transaxle, and charger, and 1 year on shrouds, seat weldments, upholstery, tires, tubes, and lights. Wear items and buyer-added parts sit outside that term. We handle the claim with you. Ask us if an extended warranty is offered for your order.

How Fast Is the Fortress S425?
The Fortress S425 has a top speed of 12 km/h (7.5 mph) on Sunrise Canada's card and the S-Series brochure.
How Far Can a Mobility Scooter Go?
Sunrise does not print a kilometre range for the Fortress S425. The brochure points to two 55 Ah Group 22NF batteries for longer journeys. Real range shortens with weight, hills, cold, and battery age. Ask us to talk through a typical Brampton day.
Does ADP Cover Scooters?

3 Wheel Vs 4 Wheel Scooter?
The Fortress S425 is a 4-wheel scooter. A 3-wheel turns tighter. If you want a leftover 3-wheel Fortress, see the 1700-DT 3-wheel. The current S-series on sunrisemedical.ca is all 4-wheel.
Can I Take a Mobility Scooter on a Plane?
The Fortress S425 is not an airline travel scooter. It is a 258 lb chassis plus two Group 22NF batteries. For a folding lithium scooter, see the Solax Transformer.
Can You Use a Mobility Scooter in the Rain?
The Fortress S425 has LED lighting and outdoor tyres. Follow the S-Series owner's manual on wet pavement. Do not spray the scooter. Ask us to walk through the manual notes at delivery.

Can a Mobility Scooter Go in a Car Trunk?
The Fortress S425 is not a trunk-fold travel scooter. Westin delivers it so you do not have to lift 258 lb.
Is the Fortress 1700 Still Available?
Sunrise lists the 1700 series as no longer available to order. The S425 is a current S-series 4-wheel. We may still have 1700-DT leftover stock. Ask us what is in the shop.
