I posted this question to BionX's web site two days ago and no answer.
Called NYCEWheels and put it to whoever answered the phone, but they accompanied their answer with the assertion that different size wheels for, say a BionX 350 unit, contain different motors - which I think undermined her credibility.
The question: If I buy a 2009 BionX 350 with a 26" wheel and then put it in a 20" wheel, can I reprogram the system so that it knows about the bigger wheel? How about the other way? Can I decrease the wheel size?
Anybody know for sure?
My real agenda is defeating the 20 mph cutoff.
I don't really want to go much over 20, but if I have tail wind or something, I don't want it doing sudden things at, say, 19.5 mph. I keep hearing the phrase "Hitting a wall".
Instead I want smooth response/activity for a few MPH over 20 - so I can do 20/21 or even 22 without it getting weird.
