Solution:

Don't sell your old bike!

However, you can buy a new Coda (2011 * $500) or a new Coda Sport!

After you've recouped from the expense of the new bike, gradually upgrade your older bike. First dissasemble the bike. Next have it powder-coated glossy black or something. Get the wheels after a couple of months or so. The following month maybe get the tires. After a few more months, get new derailleurs. So on and so forth...etc.

By this time next year, you'll have two "new" bikes instead of just one. One will be for running errands, trekking on rough terrain, and locking in marginally secure areas. The other will be used exclusively for enjoyment and recreation.

Besides, everyone should have a plan B, back-up commuter bike anyway! ...Right?
