The UK Government Cycle to Work Scheme is a very popular way of buying a new bike and associated equipment. Your employer buys the bike and equipment and then leases it to you through an interest-free salary sacrifice scheme. This means you'll get the bike and equipment tax-free and in instalments. But remember that the bike belongs to your employer rather than to you so make sure you understand what happens to the bike at the end of the lease.
The great thing about Cycle-to-Work schemes is that it can save you between 25% and 42% on the price of the bike and equipment through tax and national insurance savings.
Unfortunately Cycle to Work Schemes are only available to UK residents. Sorry.
