Frequently Asked Questions
Buying & Choosing
1) Start with body size: seat width & weight capacity
Your body size is one of the most important factors:
- If you have a standard or petite body type
â you usually donât need an extra-wide seat. - If you have a larger build (broader hips/shoulders or higher body weight)
â youâll be more comfortable and secure in a chair with more seat width and higher weight capacity.
With OAS models:
- OAS Air Pro â best for standard or petite body types
Seat width: 16.5"
Weight capacity: 260 lbs - OAS Air Ultra â for larger builds who still want a lightweight, foldable chair
Seat width: about 17.8"
Weight capacity: 300 lbs - OAS Cruise Pro â for maximum comfort with recline, headrest support, and higher weight capacity
Seat width: 17.8"
Weight capacity: 350 lbs
If you are close to or above 260 lbs, or you feel tight in a narrow seat, Air Ultra or Cruise Pro will usually feel better.
2) Think about where youâll use it most
Different models shine in different environments:
- Mostly indoors, tight spaces, apartments, narrow hallways
â You want something compact with a small turning radius.
â OAS Air Pro is usually the easiest for narrow doors, small bathrooms and elevators.
â OAS Air Ultra is still quite compact, but a bit wider. - Mix of indoor + outdoor use (sidewalks, parks, shops)
â All three models can handle mixed daily use.
â Choose based on body size + how much stability/space you want:
Standard/petite â Air Pro
Larger build â Air Ultra or Cruise Pro - More outdoor cruising, rougher paths, neighborhood rides
â OAS Air Ultra with 12-inch magnesium alloy rear wheels and Stronger Frame offer more planted, stable ride outdoors.
â OAS Cruise Pro with 12-inch aluminum alloy rear wheels offers the most planted, stable ride on grass, gravel, asphalt, and more.
Air Pro
- 39 lb with 12 Ah battery; 33 lb without battery
- 22.6 Ă 13.2 Ă 27.6 inches
Air Ultra
- 44 lb with 2*10.4 Ah battery; 36 lb without battery
- 25.98 Ă 13.78 Ă 28.35 inches
Cruise Pro
- 62 lbs with 12 Ah Battery; 57 lbs without battery
- 15.8 Ă 25 Ă 30 inches
Tip: If you lift the wheelchair often, remove the battery first to reduce carry weight.

Fitting Support
Right now, we offer fitting guidance by phone or email. Our team can walk you through key details like seat width, turning space, doorway clearance, transfers, and loading into a car. Weâll also help you decide between the Air Pro (lightweight, easy to handle, tight turning radius) and the Cruise One (roomier seat, higher weight capacity).
What to Look For During Your At-Home Trial
- Can you or your caregiver lift the chair and fit it into the trunk with ease?
- Try tight hallways and kitchensâAir Proâs ďź Air Ultra small turning radius shines here.
- Check seat width, posture, and armrest heightâCruise One ďź Air Ultra may be better if you want more space.
- Practice transfers, crossing thresholds/ramps, and gauge how far it takes you on your typical outings.
Start with how youâll use it most days. Use this quick guide:
Choose a travel-friendly model â Air Pro ďź Air Ultra if you:
- lift/store the chair often (car trunks, stairs).
- tight spaces (apartments, narrow hallways, small elevators).
- frequently.
â Travel-ready/TSA compliant lithium setup (confirm airline rules before flying). - shortâmedium daily trips and want the option to add range.
â Base range about 15 mi; with extended battery, 50+ mi
Choose a heavy-duty model â Cruise One if you:
- space and capacity over portability.
â Wider seat (48 cm / 18.9 in); higher load capacity (~330 lb). - longer or on mixed/uneven surfaces (paths, parks, ramps) and want extra stability.
- 52 lb without battery / 60 lb with 1Ă15 Ah
â Folded: 31.3 Ă 15.0 Ă 28.1 in (795 Ă 380 Ă 715 mm)
1. Your body size: seat width & weight capacity
First match the chair to your body.
Seat width & capacity for each model:
- OAS Air Pro
Seat width: 16.5"
Weight capacity: 260 lbs
Best for: standard or petite body types - OAS Air Ultra
Seat width: about 17.8"
Weight capacity: 300 lbs
Best for: users with a larger build who still want a compact, foldable chair - OAS Cruise One
Seat width: 19"
Weight capacity: 330 lbs
Best for: users who want the roomiest seat and higher capacity
How to use this:
- If you have a standard or smaller body size â
Air Pro is usually the best match (no need to carry extra width/weight). - If you have a larger build or feel tight in narrow seats â
choose Air Ultra or Cruise One for more space and stability.
2. Where youâll use it: indoors, outdoors, or both
Think about your main environment.
Mostly indoors (narrow doors, small bathrooms, elevators)
- You need: a compact footprint and small turning radius.
- Recommended:
Best: OAS Air Pro â our most compact model, designed to handle tight hallways and doorways.
Good balance: OAS Air Ultra â similar design, just slightly wider because of the larger seat.
Mix of indoors + outdoors (homes, malls, sidewalks, parks)
- You need: a balance of maneuverability indoors and enough wheel size and power outdoors.
- Recommended:
Standard/petite body â Air Pro
Larger build â Air Ultra
If you expect more uneven paths and want a more solid feel â consider Cruise One
More outdoor cruising (neighborhoods, paths, rougher surfaces)
- You need: larger wheels, stronger frame, more stability.
- Recommended:
OAS Cruise One â with 17" rear wheels and a more robust frame, it offers the most planted, stable ride outdoors.
3. Portability: weight, folding & car/air travel
Ask yourself:
âWho will fold and lift the chair, and how often?â
OAS Air Pro â lightest and most compact
- Designed as the easiest to lift and load
- Ideal if you or a family member will often lift it into a car trunk
- Great for travel and airports when paired with airline-friendly battery handling
OAS Air Ultra â wider seat, still trunk-friendly
- Folded size about 26.0" (L) Ă 13.8" (W) Ă 28.3" (H) (â 660 Ă 350 Ă 720 mm)
- Slightly heavier and wider than Air Pro, but still designed to fit most trunks
- Good if you have a larger build but still care about portability
OAS Cruise One â more robust, heavier
- Can be folded, but:
Heavier and larger than the Air series
Often better if you have a caregiver to help, or use a ramp/lift for vehicle loading - Great if stability and space matter more than ultra-light lifting
Simple rule:
- Want the lightest, most suitcase-like chair â Air Pro
- Want more seat width but still foldable and trunk-friendly â Air Ultra
- Donât mind extra weight and have help/ramp â Cruise One
Use this quick, OT-style sizing checklist at home:
1) Seat width (most important)
How to measure:
- Sit on a firm, flat chair (not a sofa).
- Ask someone to measure the widest point of your hips or thighs in a relaxed sitting posture.
- Add 2â3 cm (â 0.8â1.2âł) total for clothing and a little hand clearance on each side.
This final number is your target seat width.
Model guide (using your final number after adding clearance):
- Up to ~41 cm (â â¤16.1âł)
â You likely have a standard or petite build.
â OAS Air Pro (internal seat width â 42 cm / 16.5âł) is usually a good fit. - Around 42â45 cm (â 16.5â17.7âł)
â You need more room than a standard seat, but still want a compact chair.
â OAS Air Ultra (internal seat width â 45 cm / 17.8âł) is typically the best match. - Around 46â48 cm (â 18.1â18.9âł)
â You have a larger build or simply prefer extra interior space.
â OAS Cruise One (internal seat width â 48 cm / 19âł) gives you the roomiest seat in the OAS family.
2) Seat depth (thigh support)
- How to measure: From your back (buttocks) to the back of the knee (popliteal fold), minus 2â5 cm (â1â2âł) to avoid pressure at the knee.
- Goal: Thighs supported, 2â3 fingers of space behind the knee.
3) Seat height / footrest
- How to measure: Floor (heel with usual shoes) to back of knee + cushion thickness.
- Check: Thighs roughly level, feet flat on footplates, and ~5 cm (â2âł) ground clearance under footplates when rolling.
4) Reality check during a home trial (7-day returns)
- Transfer on/off safely?
- Any rubbing at hips or behind knees after 20â30 min?
- Can you reach the joystick comfortably without leaning?
- Does clothing (winter coat) still leave a little side clearance?
Model mapping (simple rule of thumb)
Need more interior space, higher capacity (up to 330 lbs) or you have a larger build / like extra room
â OAS Cruise One (â 48 cm / 19âł seat width, robust frame).
Larger build but still care a lot about portability and trunk loading
â OAS Air Ultra (â 45 cm / 17.8âł seat width, 300 lbs capacity).
Care most about liftability, tight turns, and travel and you have a standard or petite body size
â OAS Air Pro (â 42 cm / 16.5âł seat width, 260 lbs capacity, lightest and most compact).
Air Pro
- Typical range: ~15 miles (â24 km) per charge with the 12 Ah battery.
- Extended option: Up to 50+ miles (â80+ km) with the extended-battery setup (your stated UVP).
- Best for shortâmedium daily trips, airports, travel and city errands.
Air Ultra
- Typical range: ~15 miles (â24 km) per charge with the 2*10.4 Ah battery.
- Extended option: Up to 50+ miles (â80+ km) with the extended-battery setup (your stated UVP).
- Best for shortâmedium daily trips, airports, travel and city errands.
Cruise One
- Battery noted: 24 V, 1Ă20 Ah
Estimated real range: ~10mi per charge.
**Actual range varies with rider weight, terrain/slope, average speed, stop-and-go usage, tire pressure, temperature, and accessory load. Expect lower range on hills, rough surfaces, and in cold weather.
Quick tip to maximize range
Keep tires properly inflated, avoid top speed for long periods, accelerate smoothly, and store/charge batteries at room temperature.
Air Pro (24 V Ă 12 Ah = 288 Wh): Generally allowed for air travel because itâs ⤠300 Wh. You still need airline approval and must follow packing rules.
Air Ultra (24 V Ă 10.4Ah = 249.6 Wh): Generally allowed for air travel because itâs ⤠300 Wh. You still need airline approval and must follow packing rules.
Cruise One (24 V à 20 Ah = 480 Wh): Above 400 Wh. In most cases this will not be accepted if the battery has to be removed or carried as a spare. Many U.S. carriers apply a 300 Wh limit for lithium-ion wheelchair batteries. If you plan to fly, choose an airline-compliant pack (⤠300 Wh) or use Air Pro.
The typical service life of a power wheelchair is ~5 years under normal use and maintenance.
How to maximize lifespan (quick checklist):
Charge smart: Avoid deep discharges; partial, regular charging reduces stress on Li-ion cells. Store/charge at moderate temperatures.
Routine care: Keep the chair clean and dry; check bolts, brakes, joystick operation monthly; schedule an annual inspection.
Tires matter: Keep pneumatics properly inflated; replace worn solids/pneumatics promptly.
Operate within limits: Stay within rated capacity and avoid frequent curb drops or rough terrain beyond the chairâs designâthis preserves motors, gearboxes, and frame. (Best practice per manufacturer manuals.)

Travel & Portability
Yes, you should choose OAS Air Pro (or OAS Air Ultra if you prefer a wider seat).
OAS Air Pro uses a 24 V Ă 12 Ah lithium battery (â 288 Wh), and OAS Air Ultra uses a 24 V Ă 10.4 Ah lithium battery (â 250 Wh). Both capacities are generally within most airlinesâ limits for mobility-device batteries (⤠300 Wh), so they are usually accepted by airlines.
However, you must still follow each airlineâs procedures, notify them in advance, remove and carry the battery in your hand luggage if required, and obtain approval before flying.
Yesâjust compare your trunk opening to the folded size below and use the quick check.
Folded sizes (L Ă W Ă H)
Air Pro: 22.6 Ă 13.2 Ă 27.6 in (575 Ă 335 Ă 700 mm)
Air Ultra: 25.98 Ă 13.78 Ă 28.35 inches
Cruise One: 31.3 Ă 15.0 Ă 28.1 in (795 Ă 380 Ă 715 mm)
All our electric wheelchair are tool-free, quick-folding power wheelchairs. Most users can fold them in a few seconds after a little practice. You generally donât need to disassemble anything for transportâjust fold and (optionally) remove the battery to lighten the lift.
Air Pro (33 lb without battery / 39 lb with 12 Ah) ďź Air Ultra (36 lb without battery): For many adults, yesâsolo lift is realistic, especially if you remove the battery first.
Cruise One (52 lb without battery / 60 lb with 1Ă20 Ah): Often two-person, a ramp, or a small hoist is recommended. A strong single lifter might manage occasionally, but itâs near/over common ergonomic limits for one-person liftsâespecially at trunk height.
Car transport (trunk/SUV)
- Fold & lock: Power off, fold, and make sure the latch is fully engaged.
- Remove the battery to reduce lifting weight; place it in a padded tote (terminals covered).
- Pad + secure: Lay a blanket/mat, add soft padding around the frame/joystick, and strap it to prevent sliding (heavy items shouldnât sit on top).
- Lift safely: Slide rather than dead-lift; hold the main frame, not armrests.
Air travel (gate-check or baggage)
Tell your airline in advance youâre traveling with a battery-powered mobility aid and provide the Wh rating (Air Pro 288 Wh; Cruise One 360 Wh). Airlines must know where the battery is and how to secure the chair.
Battery rules: If your battery must be removed, it goes in carry-on only, with terminals protected (insulate/exposed contacts covered). Many policies limit lithium-ion wheelchair batteries to ⤠300 Wh.
Protect parts: Remove or secure anything that sticks out (cup holders, cushions, loose tools). Zip-tie cables; wrap the joystick with padding.
Handling card (attach to the chair): A one-page sheet with weight, fold/unfold steps, battery location, how to release/engage the brake, plus âDo not lift by armrests.â (DOT recommends attaching clear assembly/disassembly instructions for airline staff.)
On arrival: Inspect immediately and report any damage before leaving the airport; new DOT rules strengthen protections if a wheelchair is mishandled.
Keep it clean, dry, and cool; power off, fold, and store the battery correctly. Use this checklist for short-term (daysâweeks) and long-term (30+ days) storage.
Power off and make sure freewheel levers are in âDriveâ (so it wonât roll).
Fold & latch the frame; donât lift by the armrests when moving it.
Remove the battery if you wonât use the chair for a while; keep terminals covered.
Protect the joystick with a soft cover; avoid weight on it.
Dry, ventilated place away from heaters, rain, or direct sun. Use a breathable cover (not airtight plastic).
Yes. You can carry an extra, model-compatible battery for longer days.
Around town/by car: Bring a spare pack in a padded pouch, with terminals covered, and swap when needed. Use OEM batteries only to ensure BMS compatibility and maintain safety/warranty.
By air: Extra (spare) batteries are allowed only under airline rulesâsee below.
Airline rules (spare batteries)
- Watt-hour limits: Airlines follow a ⤠300 Wh per lithium-ion battery limit for mobility aids. You may carry one spare ⤠300 Wh or two spares ⤠160 Wh each, in carry-on only, with terminals protected. Airline approval is usually required.
- Installed vs. spare: If the battery is installed and protected by design, the chair is typically checked with the battery installed. Spare/removed batteries must never be checkedâcarry-on only, and protect terminals from short-circuit. Inform the airline where the battery is.
Maintenance & Care
Daily riders: Charge after each dayâs use. Partial charges are fineâno need to fully drain first.
Occasional riders (a few times/week): Charge whenever you drop near ~30â40%, or at least once a week.
Long-term storage (30+ days): Store at ~40â60%, then top up every 6â8 weeks.
1. Quick checklist (every time)
Power off; ensure freewheel levers are in âDrive.â
Fold & latch the chair; avoid lifting by armrests.
Remove the battery if you wonât ride for a while; cover the terminals.
Protect the joystick with a soft cover; donât place weight on it.
Store in a dry, ventilated, shade-cool place; use a breathable cover (not airtight plastic).
2. Battery care (most important)
Daily/weekly use: Charge after rides; OK to top upâavoid deep (0%) discharges.
Idle 1â4 weeks: Store at â50â80%; top up monthly.
Idle 1â6 months: Store at â40â60%; check/top up every 6â8 weeks.
Temperature: Aim for 50â77°F (10â25°C); avoid freezing/heat (>95°F / 40°C).
Charger: Use the original charger; donât leave connected for monthsâunplug after reaching the target level.
3. Frame, tires, cushion
Wipe off moisture/dust before storing.
Pneumatic tires: keep inflated; solid tires: roll the chair occasionally to avoid flat spots.
Long storage: stand the cushion upright or relieve pressure so it doesnât take a set.
Keep it cool, stay mostly in the 20â80% charge window, avoid deep discharges, and store around 40â60% if idle for weeks.
High-impact habits (do these first)
Charge after your ride; donât run to 0%. Aim to finish days above 20â30%.
Avoid heat. Charge/use/store around 50â77°F (10â25°C); never leave the pack in a hot car.
Partial charges are good. Itâs fine to stop at 80â90% for daily use; save 100% for trip days.
Gentle driving = longer life. Moderate speed/acceleration reduces current draw and heat.
Use the OEM charger only. Itâs tuned to your BMS and voltage.
Charging routine
Daily riders: Top up after each day (4â6 hrs typical).
Occasional riders: Recharge when near 30â40% or at least weekly.
Gauge calibration (optional, monthly): Run to ~20â30%, then charge to 100% onceâkeeps the indicator accurate.
Storage routine (30+ days)
Store the battery at ~40â60%, cool/dry place; top up every 6â8 weeks.
Donât leave on the charger for months; unplug after reaching target.
Remove the battery from the chair if storing long-term; cover terminals.
Usage factors that steal range (and age the pack faster)
High load: Steep hills, soft ground, heavy payloads.
Under-inflated tires: Keep pneumatics properly inflated.
Cold weather: Expect less range; warm to room temp before charging.
Power off, wipe with a damp (not wet) cloth and mild soap, keep water away from electronics, andâif neededâdisinfect with 70% isopropyl alcohol or an EPA-registered product. Never hose down or submerge the chair.
Pneumatic (air-filled) tires: Check pressure weekly and before long trips; inflate to the PSI printed on the tire sidewall (donât exceed it).
Solid / foam-filled tires: Inspect weekly for cuts, cracks, chunking, or flat spots (no pressure to check).
The motors are sealed and largely maintenance-free; the brakes are electromagnetic and should be function-tested regularly. Keep both dry, clean, and correctly adjusted (freewheel levers in Drive)

Safety & Usage
All OAS wheelchairs (Air Pro, Air Ultra, and Cruise One) have water-resistant, not fully waterproof, designs.
They are built to handle light splashes and damp ground, but we do not recommend riding in the rain on purpose.
Water resistance in simple terms
- The electronics and joystick are designed with splash protection (for example, ratings like IPX4, which means protection from light splashes from any direction).
- This is meant for:
Wet pavement after rain
Small splashes from puddles
Occasional light drizzle you canât avoid
It is not meant for:
- Riding in steady rain
- Very wet conditions, heavy splashes, or high-pressure water
- Driving through deep puddles or standing water
- Washing the chair with a hose or pressure washer
Long or repeated exposure to rain can affect electronics, connectors, battery, and frame over time.
Good news: all ouir wheelchairs share the same, simple joystick logicâpower on, choose a speed level, then push the stick in the direction you want to go. Release the stick and the chair brakes automatically.
