Hey leggs, no offense taken and sorry if they are bugging you about it. Not knowing exactly what it is that keeps you off the bike, here are a couple of ideas i have seen done around here.

1) At our gym, they have folks that do the MS rides on spinning bikes or recumbent exercise bikes. That way when they get tired, they can get off, if they have balance problems, they don't have to worry about weaving into traffic, and if they have heat issues, they can do it in air conditioned comfort. Some folks ride for 30 minutes, some ride for 4 hours.

2) One of the ladies in our Because We Can group has bought several tandem bicycles and she and her church work to pair up strong riders with riders with MS and they provide the tandem bike to ride. That works for some...but not for others...

FWIW, I love the idea of the Wii challenge...sounds like a terrific idea...you could even do multiple different events and give prizes to the top fundraisers and to the winners of the events. Seriously...that is one you should approach your chapter with, they would probably be very interested. I may even have to steal the idea and talk to our local chapter about it too...
