Juse get a used bike from a local bikeshop. People buy and sell them all the time and the money will keep them going.

Don't support a global conglomerate.

Spend your money where it matters.

For example, the place local to the uni where I work also trains apprentices and runs courses for homeless and vulnerable kids.

That's where the money, albeit not a lot, should be going.

Bicycle Recycling - Sales, Repairs and Hire

I know you're not in the UK, but the US must be running something similar. These guys are sponsored by motiv8, which runs educational programmes for non-university-bound people (we all shouldn't be going to university, so these are cool.)

Good luck.
