I have been riding the bike into work the past few weeks for a bit of exercise and it's all going well so far. I have borrowed a mountain bike, and are using that until I can get my road bike operational again - this may never happen as it needs 2 new wheels which may well cost more than a new bike.
Yesterday I put some road slicks on the bike instead of the knobbly tires. This took my time from 1 hour 10 mins to 55 mins. Just like that, 15 minutes gone from my time. I knew it would make a difference, but I'm quite impressed with this result.
