Introducing the 'Specialized Jett 20', the perfect bike built specifically for rapidly growing kids. We understand that finding the right balance between size and lifespan of a bike for your child can be challenging, hence, we've created a solution that grows with them.

The 'Specialized Jett 20' is carefully designed to accommodate your child's growth spurts. Our meticulous research showed us that kids' limbs grow faster than their torso, and we have kept this in mind whilst designing our bike. The Jett features child-specific touch points that adjust and evolve to keep pace with your child's growth, ensuring that they always ride in comfort.

Not just that, the Jett Multispeed offers an adjustable handlebar to fine-tune its reach as per your child's arm length. It features a 2-hole position crank paired with longer seat tubes, providing abundant scope to adjust the optimal pedalling position.

And to top it all, each component of the frame has been designed thoughtfully to make the 'Specialized Jett 20' one of the lightest bikes on the market. So, let your child embark on a joyous ride with a bike that is as adaptable as them, keeping them happily pedalling for years to come. Once they hop on it, you'll have to coax them to get off!

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.
