Frequently asked questions
‘Zeen’ is an homage to ‘Draisine’ — the proto-bicycle invented by Baron von Drais in 1816. Draisines had a saddle and handlebars, but no pedals. Riders coasted along by striding on the ground, and by all accounts the experience was exhilarating. Our Zeen clearly needed more than two wheels (see the next Q!), and the pair at the rear became our patented ‘dual-state’ casters for controlled four-wheel steering.
Zeening is likewise exhilarating!
With a Zeen one can confidently walk and coast, even if challenged by age, injury or disease. The Zeen is for people at risk of falling, or those who walk perfectly well but get tired.
It’s for those who use walkers and just plain hate the things.
It’s for wheelchair users who gave up walking prematurely because of fatigue or risk.
It’s for those determined to stay upright and put off that one-way descent to non-ambulation.
With our proprietary lifting technology, the Zeen ‘floats’ any desired percentage of your weight, so it’s hugely helpful for those who have difficulty getting up on their feet!
‘The Zeen is essentially a big comfortable saddle surrounded by four agile wheels. Once you pre-set your inseam length and desired amount of lift, the saddle will effortlessly raise you up to standing, walking and ‘barstool’ position, and gently lower to become a comfortable chair.
Zeens have two controls only — Seat-Height Lock and Brakes.
You can stand, or walk with all your weight on the ground, and the loosely fastened lap-belt and saddle-prow will still positively keep you safe.
Leaning back slightly and edging onto the wide part of the saddle allows you to ‘stride’ — to scoot easily over the ground and coast. Coasting covers a lot of ground and is surprisingly fun.
Your stride directs the Zeen where you want to go and, with no conscious effort, the chassis swivels and follows!
When coasting, one can also steer by applying either the left or right brake to influence your direction, and the brakes bring you easily to a stop.
Initial production Zeens may be available on a limited basis by fall 2021 — initially, direct from our new factory in West Chester, PA, and eventually from dealers around the world.
Unlike walkers and wheelchairs, Zeens do not stigmatize the rider. They
are cool. They are both !active furniture", and a mode of
transport. Compared to walkers, Zeens are safe, comfortable, and fast,
and do not have to be set out of the way when you arrive at the dinner
table. (Nor do they have to be retrieved in order to get back to the buffet
For those who gave up walkers because of falls or fatigue, Zeen offers a safer and more pleasant extension of walking ability and overall health, since remaining upright is strikingly beneficial for your cardiac, circulatory, muscular, digestive, and psychological fitness!
Not to mention the social benefits of standing among one’s peers vs looking up from seated limbo. (see ‘Bar-stool mode’ below!)
The Zeen is typically mounted standing, by holding the handlebars and
backing onto the saddle. Transfer techniques to and from beds, toilets,
and chairs vary according to user capability; however it"s physically and
socially beneficial to effect such maneuvers without the help of
With brakes engaged, one may transfer solo between bed or toilet in one of two ways: either by sliding laterally with the Zeen in seated position; or by bracing your forearms on the armrests to help you up. Once standing, you can turn and back onto the saddle as usual.
Phenomenally maneuverable. Zeens sport patented 'Dual-State Casters'
for perfect forward tracking, uncanny four-wheel steering and easy
lateral and rearward motion.
A Zeen occupies slightly more floor-space than a rollator or wheelchair — and can be instantly folded to take up as little as 10” of space next to a wall.
‘Barstool Mode’ is at the appealing heart of Zeening. It’s when you come
to a standing stop in the midst of a social gathering, put your feet on the
footrests, shift back on the saddle and join the crowd!
Instead of being isolated on a wheelchair with your head at waist-height, you are up at your natural standing eye-level with both hands free, joining the conversation in the warmth of human conviviality, with perfect ease and no jeopardy of falling.
Zeening is easier, faster, and arguably more secure than 'walker-ing', and can keep up with an energetic wheel-chair user, plus it's less tiring than either, and way more social, since encounters along the way are at eye height, and with nothing mechanical in between you and your friends.
Our initial Zeen trials indicate that people immediately love feeling of
being more secure.
They like that the Zeen is both their mode of travel and their comfy chair, with no dangerous transitions.
They love the relative rapidity and ease of coasting.
They cherish the face-to-face quality of human interactions.
They love being able to pop up and down from a seated position with no strain.
And they particularly like not having to set aside and keep track of a walker or wheelchair while dining.
Those initial few who had had access to a Zeen at home report happily cooking, working, cleaning, doing the wash, reaching into closets and cabinets, etc. with no contraption in the way!
“There’s nothing ahead of you — nothing ‘in your space’ — and what’s behind is invisible… follows you like a ghost!”
One old gentleman even mentioned the ease of putting on his pants!
Rehab protocols include those involving mobility and those related to other aspects of life. Many rehabilitation accessories and protocols are adaptable to the inherently safe and dramatically mobile Zeen platform, so patients can be more independent, and therapists are freed up to attend to other tasks.
Yes. Certainly. As with any human activity, excess exuberance or
carelessness can be dangerous. One would have to work much harder to
tip over a Zeen than a walker or wheelchair, but a certain amount of
caution is prudent:
- You can safely lean as far forward, backward or sideways as you like, but don't, for example, back up rapidly in Barstool Mode without scouting in advance for obstacles that might trip you up.
- When walking uphill or down, slightly lower your saddle height so your feet have better traction. Likewise when stepping on or off a curb. Either is easy if you first lower the Zeen saddle about as much as curb height. Then negotiate the curb in a standing position, stepping up or down while appropriately lifting up or lowering the front of the Zeen. The rear wheels will simply follow up and over as they get to the curb.
- When approaching ramps, hills and curbs, lower the saddle height; and keep both hands on the brake levers when coasting! In fact, don't ever coast downhill at high speed! If you encounter a slope, up, down or sideways, just walk — with the saddle lowered enough to give you good traction — and keep your hands on the brake levers. Bringing the Zeen along with you will not be difficult and it will continue to help protect you from falls!
That’s a tough one. We’re working on that of course, but don’t try it with your Zeen!
See 'hazards' above for tips on hills and curbs. Lightweight, folding
Zeen models with pneumatic tires can definitely be of use outdoors,
even on gentle hills, if you have the core strength to propel them up over
Even if unsteady at ambulating, such as from disease or stroke, the Zeen can still help protect you from falling unless you undertake a hill that's too steep for braking, or a side slope that's too extreme for the walking ability you retain. (Common sense and your accumulating Zeen experience will be your reliable guide.)
Rain is no particular obstacle if the ground is smooth since Lightweight Zeens are waterproof, and with a seatbelt it's easy enough to devote one hand to your umbrella.
We would definitely not recommend riding a Zeen in snow, ice or high wind.
The Zeen folds laterally with one upward pull to be 33" long x 39" tall x 10" wide folded. Our ‘Car-Loader’ accessory clips to rear seat-backs or headrests and requires half the effort of simply lifting your Zeen into a cargo area or trunk.
