There aren't any TRIKE shops in WA, OR or ID that I know of. It's a big
problem for trike mfrs. Silverdale sells Catrike. Coventry (Portland)
sells a few brands and there is a recumbent shop in Wenatchee (Go
Bent?). This black hole for trikes even has had me considering opening
a shop. If you want to add a 3x9 Angle Lake or Angletech (mail order,
Dale's brother Kelvin) are your best choices. Angletech specializes in
DualDrives and he is the only shop I know who does this. As for just
decent bike shops, I dealt with Center Cycle out by IKEA for many
years. Dave and his crew are very friendly, but I never had them work
on recumbents and I doubt they do DualDrives.
