Bike and frame supply has vastly improved since the pandemic, but pre-ordering is still essential for some models and sizes. Hope HB916 frames are made to order too, so we have updated our pandemic bike deposit policy to take the current situation into consideration.

Please note - we can only deliver complete bikes to UK Addresses.

The ETA's (estimated times of arrival) we quote are from the information provided by the manufacturers and distributors. These dates are not guaranteed, as the manufacturers are also at the mercy of component suppliers. We will tell you the same dates as the manufacturer tells us.

We only take deposits on bikes we have on order with suppliers and have confirmation that we are going to receive them. We want to make it clear that there might be issues outwith our control that will prevent us from supplying the bike you want. If that happens, we will do our best to provide an alternative.

Deposits are non-refundable, except for when an ETA date changes by a month or more. If it looks like the date might change, we will do our best to find you an alternative.

If a bike arrives earlier than expected, it will be offered to the person with the oldest outstanding deposit, then the second, and so on. We'll then offer the bike to anyone with a similar bike on order. We should point out that this is a rare occurrence!

Bikes and frames up to £3500 require a £500 deposit.
Bikes over £3500 require a £1000 deposit.

We ring-fence deposits in a separate bank account until the balance of the bike or frame is paid, then the bike or frame is delivered.

We've tried to be as honest and open about the situation as it stands and not make promises we know we are not in the position to fulfil! We have great relationships with our suppliers, and we will work with them and you to try to get you your bike as soon as possible.

If you've read this and have any questions or would like to place a deposit, please phone us on 01330 828562.

We offer free UK delivery on all bikes unless bought through a Ride To Work Scheme.

We don't currently deliver complete bikes outside the UK.

Custom-built bikes can be delivered in kit form (for you to assemble) - we can include shipping to your country in your quote.

Kids Sized Pedals

Sale price bikes bought though Cycle To Work schemes will have a handling fee added.

This information is intended as a guide only.

Cycle To Work is a Government Initiative to encourage cycling to work. The idea is that by cycling to work, you get fitter and healthier, and at the same time reduce congestion and improve air quality.

In simplest terms, your employer pays for the bike, and you hire it from them through salary deductions. At the end of the hire period, the employer can sell you the bike. (Until the bike is paid for, you hire it from your employer, so don't get fired).

Your employer might administer the scheme themselves, or use a third party like one of the following:

Green Commute Initiative
Cycle Solutions
My Benefits World

If your employer doesn't offer Cycle To Work as a benefit, you can send them this employer information from the Government that outlines how it all works.

Taking inspiration from the award-winning Nukeproof Scout adult hardtail range, the Cub-Scout 20” has been designed from the ground-up as a proper mini-hardtail mountain bike. It has been designed to allow rippers from around 5 years old to learn the ropes of riding. Designed to inspire confidence on the trails and act as the perfect platform for progression, with optimised geometry and size specific components. Developed and tested with our World Class test team (the Nukeproof team's own children), Nukeproof have created a class leading lightweight kids bike range to inspire and nurture the future generations of Downhill World Cup or Enduro World Series champions. 

The range of Cub-Scout Hardtails are available in 20”, 24” or 26” options; meaning that there should be a bike to suit kids of all sizes from aged 5 and up. Each bike features a lightweight custom butted 6061 Alloy frameset with bang up-to-date long, low and slack tiny human optimised geometry.

Updated Kids Specific Components:

Proper fit and function of components is essential for kids bikes because adult components are not optimised for smaller people. To ensure that these bikes fit and function perfectly, Nukeproof took the time to test and develop their own or work with their partners to select the best kids-specific components they could find on the market.

Kids Specific Parts Include:

  • Nukeproof Urchin Saddle, Grips & Handlebars
  • Custom tuned forks for young rippers
  • Specific resized cranks
  • Kids specific brake levers
