A quality bike is an excellent investment, especially if you plan to use it long-term. However, if you are still starting and want to spend less on a practice bike, you can purchase Bikes Online Ex Demo Bikes. These discount bikes are slightly used and offered at low prices, perfect for anyone looking for a great bike at an unbeatable value.
Here at Bikes Online, you'll find various options for your choice of activity, from gravel and Ex Demo Bikes to electric and hybrid bikes. You may browse our extensive online catalogue and learn more about them.
What is an Ex Demo?
Ex demo is short for ex-demonstration, which refers to vehicles on display used for test driving or utilised for marketing. These kinds of bikes range from unused but opened to barely used, and they are significantly better performing than second-hand mountain bikes.
Bikes Online's team of professional mechanics perform rigorous quality checks on the Ex Demo Bikes for Sale to ensure that every customer gets a top-performing bicycle. Therefore, you can be confident that they are as sturdy and reliable as the new road, electric or mountain bikes.
Ex Demo Bikes: A Cost-Efficient Option
We are all about being efficient and economical, so we don't let our barely-used bikes go to waste. And the great thing about these Ex Demo Bikes? You save while receiving a first-rate and high-grade two-wheeler that will last a long time.
In this range, heaps of bicycles will suit your style and preference – from ex demo road bikes to mountain bikes.
These are the characteristics of a Bikes Online ex demo:
- Small scratches or superficial damages during transit.
- Bikes used for outdoor promotional photo shooting or test rides.
- Bikes returned under our Free 14-Day Bike Return.
We are selective on which slightly used bikes to categorise under this category. Once these bikes arrive at our workshop, our qualified mechanics unpack, assemble, inspect and test them before labelling them as ex demo.
Ex Demo Bikes Quality Control
Bikes Online values transparency. That is why we photograph and report all cosmetic damage on the specialised ex demo bikes and post them on their product pages. These photos are there for you to view so you can make an informed decision before you purchase — all part of the worry-free shopping experience we aim to give you!
IMPORTANT NOTE: Some components will be in new condition when getting ex demo bikes from our range, usually for bikes with less than 10 km of travel. The company replaces their wearable parts such as bearings, chains, hubs, pads, cassettes and chainrings to be fresh and have a complete life cycle expected of newly-purchased bikes.
In cases like that, our mechanics will do their best to clean all bicycles from any dirt acquired during the bike's short travels. However, it is only sometimes possible to remove them entirely, especially from tyres or other inaccessible parts.
To summarise, here is the process that our ex demo range goes through when handled by our qualified mechanics:
- Unpack and meticulously inspect the bike for any damage.
- Replace any component that suffered structural damage.
- Assemble, tune and test the bike.
- Document any damage found on the bike post inspection and service.
- Repack the bike, create the ex-demo product and input the appropriate discount.
- The bike is ready to be sold as an ex-demo.
Our Bicycle Consumer Guarantee Policy covers all Ex Demo Bikes in this range from the date of purchase. So, rest assured that any cosmetic damage or mechanical defect covered by the policy will be covered under warranty too. No need to stress!
If you have any questions or need further assistance, please don't hesitate to contact us. Our support team is more than willing to assist with your concerns.
