When we 1st reported my wife had a hard time getting up the 2" apron at our garage entrance. Since then we read the manual (always helpful) and adjusted the anti tip arms that extend above the ZX-1 shroud and press against the backrest tubes. We moved the 2 screws (on each side) and moved them further back on the plate by one position. Now she approaches the apron, pushes head and shoulders against backrest while moving forward - the front casters pop over the apron. The front casters were too front loaded to jump obstacles in the original position as shipped, the manual has a table which advises which holes to pick based on chair COG. A lot of forethought went into the ZX-1.

A big concern of mine with those hitches behind the vehicle, is what happens if someone rear ends you and ruins your expensive powerchair/zx1? Also, what about weather? Raining or snowing?Board Member of Assistance Dog Advocacy Project working in Education. Feel free to ask me any service dog questions!

The actual theoretical speed is:
Tire circumference = 10 * 3.14 = 31.4 inches
or 2.62 feet
Motors turn 4600 RPM gear ratio is 21
So RPMs at axle is 219
Axle RPM * Wheel Circumference = Feet per minute
So 219 * 2.62 = 573.78 fpm
573.78 * 60 = 34426.8 fph
34426.8 / 5280 = 6.52 mph
I think if you account for user weight road drag and air resistance it would still be closer to 6 than 5.

If it was damaged by UPS in a drop, it would've had to have been a big drop. Look for damage like that.
I'm positive UPS dropped the box that's why there is a slight bend on the support that holds the Wheel, I just noticed a big gap on the box in my garage that I never noticed before. I might not only be disabled but I am blind, But somebody else took the packaging off so that's why I didn't notice. Here is a picture of the box.

I wonder when that sticker was applied, before or after dropping the box... Any bets?Board Member of Assistance Dog Advocacy Project working in Education. Feel free to ask me any service dog questions!

I'm gonna try with my Garmin GPS see what that says, i'll let you know.

Do you know why they got rid of the polymer/elastomer? Isn't suspension the whole point in the Frog Legs, and without that it does not make sense?

Oops, just read this after I had already replied.

The swivel radius would also be tighter.Partner of an incredible stroke survivor. Limitations: hemiparesis and neglect (functional paralysis and complete lack of awareness on one side).
