Cycle to Work Scheme: Affordable Riding for UK Employees

Unlock a cost-effective way to own the bike of your dreams through the Cycle to Work Scheme. This initiative, available to employees in the UK, lets you enjoy the benefits of cycling while saving on your bike purchase.

With the Cycle to Work Scheme, you can use your pre-tax salary to acquire a brand-new bicycle and essential cycling accessories. This means significant savings for you, as your salary sacrifice reduces both your income tax and National Insurance contributions.

The process is seamless: Choose the bike that suits your needs and budget from our extensive range. Your employer will then set up a salary sacrifice arrangement, spreading the cost of your bike over a specified period, typically 12 to 18 months.

Once the salary sacrifice period ends, you have the option to own the bike outright for a nominal fee, ensuring you get to keep and enjoy your trusted two-wheeled companion for years to come.

Experience the freedom of cycling, save money, and reduce your carbon footprint with the Cycle to Work Scheme. Join countless UK employees who have already embraced this eco-friendly and wallet-friendly way of commuting.
