COVID-19 Important collection and delivery information
Due to a combination of new working practices and demand our lead times for both collection and delivery have been extended.
Where delivery times are stated as a month this is based on the latest information from the manufacturer. These dates should be treated as a guide and may be subject to change. Due to an increase in global demand for bicycles and the disruption in supply during the COVID-19 pandemic supply chains have become very strained. Lead times are based on factory and shipping schedules both of which can be disrupted by delays in component supply and shipping/port capacity.
Should you place a future order with us for a bicycle we will monitor the bike’s ETA and keep you informed of any changes.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
The following finance options are available to apply for online immediately. If you are collecting your bicycle in store you can arrange your finance prior to visiting the store by selecting the required finance method as well as Click & Collect.
