Re: another canadian
I do hope your disability isn't the type that would affect your balance or ability to handle the bike at low speeds, where they can be a bit clumsy. But I suppose you'll already have considered this.
And I hope you're able to do some basic bicycle maintenance. It's really all but necessary for the owner/operator to do some of this sort of stuff. Otherwise you're dead in the water too much of the time.
I don't mean to be discouraging. It's meant more as a 'heads up'. But if these things won't be a problem, then you're very likely to have a blast.
