Used e-bikes: 10 expert tips for finding the best pre-owned e-bikes

Are you looking to find the best used e-bike? If so, it pays to take a close look! The second-hand market is booming, as more and more people are choosing e-bikes over cars. E-cargo bikes, in particular, are seeing strong growth: sales increased by 14.5% in 2023. This makes used e-bikes an attractive option because they hold their value well and can save you a lot of money. But be careful: not every bargain lives up to its promise. With a few clever tips, you can quickly discover what really matters.

Key Insights

• Consider carefully how you intend to use your used e-bike to find the right model.

• Prefer buying from dealers or refurbished providers if you want security and a warranty.

• Check the battery age, capacity, and charge cycles carefully to avoid expensive surprises.

• Thoroughly test the motor, brakes, and electronics during a test ride before you buy.

• Ensure you have complete documentation and a bill of sale to stay on the safe side legally.

Used e-bikes: Choosing a type

Intended use

Before you decide on a used e-bike, you should think about how you want to use it. Do you want to ride it to work every day, go on tours on the weekend, or do you need a bike for grocery shopping? Many people underestimate how much the intended use influences the choice.

Tip: The more precisely you know what you intend to do with your e-bike, the more satisfied you will be later on.

Studies show that sporty riders keep their e-bike for an average of three years, while others use their bike for up to seven years. Interestingly: 30% of sellers do not even know what their bike was originally designed for. This often makes reselling more difficult. When you buy used e-bikes, a clear plan helps you find the right model and makes it easier to sell later. Experts recommend passing on used e-bikes after a maximum of 1.5 years because technology evolves quickly.

Model types

There are many different e-bike models. Each one suits a different purpose. Here is a brief overview:

• City E-bikes: Perfect for the city, short distances, and your daily commute.

• Trekking E-bikes: Ideal for longer tours and mixed terrain – they are considered true all-rounders.

• Mountain E-bikes: For off-road adventures and sporty riders.

• Cargo E-bikes: Great if you want to transport a lot, such as groceries or children.

Manufacturers like trenoli offer various series with different motors and batteries. Models like the TANARO or LIVENZA regularly receive top marks in tests and are praised for their versatility. This shows: making the right choice when buying used e-bikes ensures more riding pleasure and less hassle. So think carefully about which model fits your daily life.

Purchase sources

Private or dealer

You face a choice: would you rather buy your used e-bike privately or from a dealer? Both paths have their pros and cons. Many people look first on classifieds or in online forums. You can often find the cheapest prices there. You can sometimes get a used e-bike privately starting at 2000 euros. That sounds tempting, but you bear the full risk. As a layman, you often cannot detect damage to the battery or motor. There is no warranty, and sometimes a proper bill of sale is even missing.

Dealers offer you more security. They professionally inspect the e-bikes and usually provide you with a one-year warranty. You get a bill of sale and precise technical data. The risk of hidden defects is much lower. However, you often pay a bit more at a dealer. Many buyers appreciate this security: according to a survey, 57% of prospective buyers prefer dealers with a warranty, while 41% prefer buying privately.

Here you can see the most important differences at a glance:

Tip: Don't just let price be your guide. Security, warranty, and condition are just as important when buying used e-bikes.

Refurbished

Refurbished e-bikes are an exciting alternative. Providers like Rebike or Upway take used bikes, inspect them in over 100 steps, and replace worn parts. The battery and motor are professionally tested, and software updates are included. These e-bikes feel almost like new. You get a two-year warranty on the motor and battery. The service quality is even certified by TÜV Rheinland. This gives you peace of mind and protects you against unpleasant surprises.

Refurbished e-bikes usually cost a bit more than private offers, but often start at 3500 euros. In return, you save up to 60% compared to a new bike. You benefit from verified technology, high customer satisfaction, and a dense network of service workshops. If you value security and quality, it is worth taking a look at these offers.

Checking the battery

The battery is the heart of your used e-bike. This is where it’s decided whether you will have long-term enjoyment or quickly have to spend a lot of money on a replacement. Many underestimate how important it is to take a close look at age, capacity, and charge cycles. Let’s take a look together at what you should watch out for.

Age and capacity

Always ask about the age of the battery. A battery does not last forever. Experts recommend that the battery should not be older than two years at the time of purchase. Older batteries often lose performance and range. The capacity indicates how far you can get on a charge. For the city, 400 to 500 Wh is usually sufficient. If you are planning longer tours or ride uphill often, you should look for at least 700 Wh.

Here are the most important facts at a glance:

Tip: Ask to see the remaining capacity. If it is under 80%, an expensive replacement is usually due soon.

Charge cycles

The number of charge cycles tells you how often the battery has already been fully charged. Most batteries last for 700 to 1,000 charge cycles before performance drops significantly. Many sellers don’t know this exactly. Ask specifically or request a printout from the diagnostic software. Workshops or dealers can usually check this quickly.

Caution: A new battery can easily cost 500 to 900 euros. Therefore, always check the age, capacity, and charge cycles before you finalize the purchase. This will protect you from unpleasant surprises and ensure you enjoy your e-bike for longer! 🚲

Motor & Electronics

Functional test

The motor is the centerpiece of your e-bike. Without a functioning motor, riding isn't fun. You should always test the motor before you buy a used e-bike. Switch the bike on and check if the display starts up. Test all support levels. Does the bike start smoothly in every mode? Listen carefully: a healthy motor runs quietly and smoothly. Is there any clicking or rattling? Then something is wrong.

It is best to take a short test ride. Pay attention to how the motor reacts when you start pedaling. Do you feel a jerk or is there a delay in support? That can indicate problems. Also, test whether the motor works properly at higher speeds. Have the seller show you how the display works. Check if all readings like speed, battery level, and range are correct.

Tip: Have the seller show you how to change the support levels. That way you can quickly tell if everything is working.

Sources of error

Many used e-bikes have small quirks in the electronics. Some faults you recognize immediately, others only later. Here is a list of typical problems:

• Error messages on the display: Look out for warning symbols or flashing lights.

• Loose connections: Cables on the motor or display can be loose.

• Sensors defective: Does the motor sometimes not engage? Then a sensor might be broken.

• Software problems: Sometimes an update helps, sometimes it doesn’t.

Caution: Electronic problems can get expensive. When in doubt, have the bike checked by a workshop. That way you play it safe and enjoy your e-bike for a long time! 🚲

Frame & Brakes

Paint & welds

Do you want to enjoy your used e-bike for a long time? Then take a very close look at the frame. The frame is the backbone of your bike. Small damages can lead to big problems later.

Take your time and check the following points:

• Paint damage: Do you see scratches, dents, or chipped paint? That can indicate accidents or rough treatment.

• Rust: Rust can hide in hidden places, especially under the bottom bracket or at the dropouts. Rust weakens the material.

• Welds: They connect the tubes of the frame. Look for cracks, uneven seams, or tiny hairline cracks. These are warning signs.

Tip: Run your finger over the welds. Do you feel unevenness or see tiny cracks? Then it’s better to walk away from the purchase!

A stable frame ensures safety. A damaged frame can break. That is dangerous.

Brakes & tires

Brakes and tires are genuine wear parts. They decide how safely you ride. Always check them before buying.

Here is a short checklist:

1. Brakes: Pull the brake levers firmly. The brakes must engage immediately. Do they squeak or grind? Then they are worn out or improperly adjusted.

2. Brake pads: Take a look at the pads. Are they very thin or worn unevenly? Then a replacement is due soon.

3. Tires: Check the tread. Are the tires worn out or brittle? Cracks or bulges are a no-go.

4. Air pressure: Press the tires with your thumb. They should be firm. Soft tires indicate leaks.

Note: New brake pads or tires don’t cost the earth, but they show how well the previous owner maintained the bike.

If you pay attention to these points, you will find a used e-bike that is safe and reliable. 🚲

Documents

Service history

Do you want to know how well a used e-bike has been cared for? Then take a look at the service history. It shows you whether the previous owner has regularly maintained the bike. A well-maintained e-bike lasts longer and is safer to ride. Ask for maintenance records or a service booklet. Many workshops stamp every inspection. This way you can see at a glance when the brakes, chain, or battery were last checked.

Tip: A complete service booklet is a real plus. It shows that the owner took their e-bike seriously.

Some sellers also have invoices for repairs or replacement parts. These documents help you to better assess the condition. You can tell if important parts like the battery or motor have ever been replaced. This gives you security when buying.

Purchase receipts

Purchase receipts are worth their weight in gold when buying used. They prove that the e-bike is not stolen. Always ask to see the original invoice. There you will find the date of purchase, the frame number, and often the serial number of the battery. These data should match the bike.

Here is a short checklist for you:

• Original invoice available?

• Frame number on the frame and the invoice identical?

• Serial number of the battery noted?

• Manual and technical data sheet included?

• Original accessories like charger, keys, and display present?

Note: If important documents or accessories are missing, you should be cautious. Without proof, there may be problems later, for example with the warranty or in the event of theft.

With complete documents, you are on the safe side. It will be easier for you to resell your used e-bike later and you will always have all the information at hand.

Test ride

A test ride is mandatory when buying a used e-bike. It is the only way to find out if the bike really suits you. You will feel immediately whether everything works and what the e-bike feels like. Take your time and test the bike calmly. Ideally, ride on different surfaces: a bit uphill, over cobblestones, and on smooth asphalt. This will give you a good feel for the bike.

Testing riding modes

Almost every e-bike has different riding modes. You can choose between Eco, Tour, Sport, or Turbo. Each mode changes how much the motor supports you. Cycle through all modes while riding. Can you feel a difference? The motor should work smoothly in every mode without jerking.

Here is a short checklist for you:

• Eco mode: Low support, ideal for long distances.

• Tour mode: More power, good for everyday use.

• Sport/Turbo mode: Maximum support, perfect for inclines.

Tip: Also test how easy it is to ride without motor support. A good e-bike is comfortable to ride even without assistance.

Brakes & motor

Now check the brakes and the motor in everyday conditions. Pull the brakes firmly. The bike should come to a stop immediately without squeaking or grinding. Test both brakes individually. Do they feel different? If so, something might be wrong.

The motor must run quietly. Do you hear strange noises, such as clicking or grinding? That is a warning sign. Accelerate and brake several times. The motor should deliver power evenly and not jerk.

Checkpoints	What you should test
Brakes	Do they engage quickly and safely?
Motor	Does it run quietly and smoothly?
Support	Does it work in every mode?

Note: If you feel comfortable on the bike and everything works, you have a good sense of your purchase. Do not let yourself be rushed and trust your gut feeling! 🚲

Legal aspects

Proof of ownership

Do you want to be sure that your used e-bike really belongs to the seller? Then always ask for proof of ownership. Without this proof, you risk buying a stolen bike. That can cause real trouble later on. The police can even confiscate the e-bike.

Here are the most important documents you should see:

• Original invoice: It shows who bought the bike first.

• Frame number: This number is on the frame and on the invoice. Both numbers must match.

• Theft register: Some e-bikes are registered in a database. Ask for proof.

Tip: Have them show you the frame number and compare it with the invoice. This protects you from fraud.

If the seller has no papers or answers evasively, you should be careful. Better to ask one time too many than to have problems later!

Purchase agreement

A purchase agreement protects you and the seller. It records all important information. This prevents misunderstandings later on. You can write a simple contract yourself or use a template from the internet.

The purchase agreement should include:

1. Name and address of you and the seller

2. Description of the e-bike (brand, model, frame number, battery serial number)

3. Purchase price and payment method

4. Date and place of purchase

5. Note on known defects

Here is an example of a simple table in the contract:

Item	Example
Buyer	Max Mustermann, Musterstraße 1
Seller	Erika Beispiel, Beispielweg 2
E-bike	trenoli TANARO, frame no. 123456
Battery	serial no. A987654
Price	€2,200

Note: Both parties should sign the contract. That way you are on the safe side if there are any questions later.

With a clear purchase agreement and proof of ownership, you are playing it safe when buying used. This allows you to enjoy your new e-bike with total peace of mind! 🚲

Price & depreciation

Market prices

You are probably wondering: How much does a used e-bike actually cost? Prices vary widely. Many factors play a role. Age, condition, brand, and features determine the price. A rough rule of thumb: An e-bike loses about 20% of its value in the first year. After that, the price continues to drop each year, but more slowly.

Here is an example for you:

Age of e-bike	Estimated depreciation	Price (at a new price of €3,000)
1 year	approx. 20%	approx. €2,400
2 years	approx. 36%	approx. €1,920
3 years	approx. 50%	approx. €1,500

Tip: Always compare several offers. Use online portals like eBay Kleinanzeigen, rebike, or Upway. This will give you a feel for fair prices.

Pay attention to whether the battery and motor are still in good condition. A low price won't help you if you have to buy expensive spare parts right away.

Maintaining value

Do you want your e-bike to lose as little value as possible? Then maintain it well! A clean, serviced bike brings more money when reselling. Keep all invoices and service receipts ready. They show the buyer that you have taken care of it.

Here are a few simple tips for you:

• Store your e-bike in a dry, protected place.

• Charge the battery regularly, but not to 100% capacity.

• Have it serviced once a year.

• Keep original accessories and the instruction manual.

Note: A well-maintained e-bike with complete paperwork sells faster and at a better price. You save real money in the end! 🚲💡

Additional services

Warranty

A warranty gives you security when buying a used e-bike. Many dealers and refurbished providers offer a warranty of 12 to 24 months. This protects you from expensive repairs if the motor or battery suddenly fail. Private sellers usually do not provide a warranty. You then bear the full risk.

Tip: Always ask about the warranty terms. Read the fine print. Some warranties only cover specific parts, such as the motor or battery. Wear parts like brakes or tires are often excluded.

Here is a quick overview of what you should keep in mind:

• How long is the warranty valid?

• Which parts are covered?

• Is there a workshop near you?

• Does the warranty have to be transferred upon purchase?

A warranty makes the difference if you want to be on the safe side. You can ride more relaxed and have fewer worries.

Insurance

Insurance protects you against high costs if your e-bike is stolen or damaged. Many insurance companies offer special policies for e-bikes. You can insure against theft, vandalism, or even accidental damage.

Take a look at these options:

Type of insurance	What is covered?	Who is it suitable for?
Theft insurance	Protection against theft	For everyone, especially in the city
Comprehensive (Vollkasko)	Includes damage from falls, vandalism, battery	For expensive or new e-bikes
Liability	Damage to third parties	Mandatory for S-pedelecs

Note: Many household insurance policies only cover e-bikes when they are stored at home. When you are out and about, you often need an extra policy.

Do you want to use your used e-bike for a long time? Then insurance is worth it. It gives you peace of mind, no matter where you are riding. Ask about suitable offers at the time of purchase or compare policies online. This way, you are always on the safe side! 🚲

With good preparation, you will find the right e-bike and save real money. Take a look at the most important checkpoints:

1. Test the motor, brakes, tires, and electronics.

2. Check the battery and ask about charge cycles.

3. Take a test ride and pay attention to how it handles.

4. Check documents and service history.

Also keep an eye on depreciation:

Age of e-bike	Estimated depreciation
1 year	20–30%
2 years	30–40%
3 years	40–50%
4 years	50–60%
5 years and older	60–70%

Use this checklist next time you are looking for used e-bikes. This way, you will make a safe and smart decision!
