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.

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.

Unlock a world of adventure and redefine your mountain biking experience with the Transition Spur. This remarkable bike is designed to effortlessly connect you to the trail, making it feel like a natural extension of your body. With its lightning-fast and efficient performance, it provides an almost weightless sensation and precision control, urging you to conquer steeper climbs, venture farther, and conquer any descent you encounter along the way. Prepare to be amazed as you enjoy the newfound speed that comes effortlessly, even in places where you're used to constant pedalling. But don't be fooled by its lightweight and uphill-oriented features; the Spur requires no adjustments to handle descents like a pro, and you might find yourself descending even faster.

Transition's "GiddyUp" suspension system is engineered to intuitively adapt to a wide range of setups. Sometimes you just want to grab your bike and go without worrying about fine-tuning your settings. With GiddyUp, you can hit the trails with confidence, knowing your ride will always feel exceptional.

The Spur boasts nearly 30% progression and maintains a consistent linear rate of change, striking a perfect balance between support and sensitivity to small bumps. The anti-squat feature is finely tuned to enhance pedalling efficiency and acceleration without interfering with the suspension when it's needed most.

The GiddyUp suspension system and a one-piece flex stay rear triangle, is optimized to work seamlessly with inline-style rear shocks. It offers a well-balanced ride when paired with 120 mm travel forks. Riders have the flexibility to add or remove volume spacers in the rear shock to match their unique riding style, and there's ample control for those rowdy moments. The Spur comes with 120 mm of rear wheel travel when equipped with the supplied 190 mm x 45 mm stroke shock. If you prefer a shorter travel experience, you can opt for a 190 mm x 40 mm stroke shock to reduce rear wheel travel to 100 mm.

With a versatile sag range of 25% to 35%, you can fine-tune your bike's feel to suit your preferences – from a firm and responsive ride to a more supple and active one. Best of all, there are no remotes, levers, or knobs to fiddle with; simply grab your bike and GiddyUp, and hit the trail with confidence.
