To add just a bit to this, I found a Google reference to use of a
BionX electric assist system on the Greenspeed site by a dealer, but
it mentioned the minimum size of a BionX wheel is 18", and the GT3 has
16" wheels, which would seem to rule that out as an option. Looks
pricey too, starting at over $1G. IF it's going to cost as much as a
GTT, we'd likely rather just have a GTT.
