You don't need masses of bits and bobs, but there are a few vital things that you should price into your budget for commuting. Check out the clothing section – start with a rainproof jacket to arrive dry. Also consider as a priority:
1. A good lock. Prices range from £20 to £55. See the security page for details
2. Lights – unless you're a very occasional commuter, or work very favourable hours, you'll need to set yourself up with some illumination. See the lighting page.
3. If you have to carry stuff, get a rack to pop your bag on and make the bike do the work. Prices from £20. For small amounts of gear, you can simply bugee a bag to the top, but later you may want to consider panniers. See the luggage page.
4. For year-round use, invest in a pair of mudguards. They help keep you dry, especially your shoes and that strip down your back. They protect your bike from road grime, too, which helps everything last a little longer. As an added bonus, they make your bike a little less sexy, reducing its appeal to theives.
5. It's worth having a small toolkit, with a spare tube and a pump.
Later you may want to branch out in the clothing, luggage and accessories directions, but if you're starting from scratch, you may want to build up slowly.
Your year's free servicing covers fitting accessories, so if you decide you need extras later, arrange for us to pop them on your bike for you.
In an ideal world, your place of work would have lots of lovely facilities to make it easier to commute. Secure bike parking saves you from having to tie your beloved steed to a railing in the rain, and from worrying about it. A shower and changing facilities are helpful, so that you can wear your cycling clothes then change into whatever you have to wear at your job. Smart clothes suffer badly when cycled in, and don't often do that well at keeping you warm and dry. If you think all this would cost too much for your employer to provide, work out how much they spend annually on car parking spaces.
