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.

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:

Vivup
Green Commute Initiative
Cycle Solutions
My Benefits World
Cyclescheme

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.

Transition's bike-for-everything is now available in a more wallet friendly alloy construction. 140 mm of composed GiddyUp travel, Enduro MAX sealed bearings with additional bearing seals and bottle and accessory mounts are all stand-out features of the new alloy Sentinel frame.

Looking for the basis of a solid, dependable 29er that's up for any UK trail and won't have you fretting when it picks up a few dings and scrapes? This is the frame for you!

While we're happy to supply this as a frame only, we specialise in custom-built enduro bikes. We can build you a new bike around this frame - a bespoke custom build, with exactly the suspension, brakes, and drivetrain you want - no compromises!
