Buying a powerful electric scooter second-hand: Key things to check
A powerful used electric scooter can be a great deal, or a complete disaster. The battery, steering, brakes, and modification history make all the difference, and most of these factors can be checked in just twenty minutes if you know where to look. Here's the checklist we follow in the workshop when a customer brings us a scooter for inspection before they buy it.
The essentials
- The battery is the most expensive component: its condition determines the actual value of the machine.
- There's a noticeable play or looseness in the steering column when the vehicle is stationary, with the brakes applied, and when pushing the handlebars.
- Discolored connectors, water stains, damaged screws: all signs of a difficult life.
- A modified machine (with its performance unlocked, or with controllers replaced) often loses its manufacturer's warranty.
- For transactions between private individuals, only the warranty for hidden defects applies. Please request invoices and proof of purchase.
1. Documents and history
Start by checking what doesn't require any tools. Ask for the original purchase invoice, maintenance records, and the date of first use. Verify that the frame's serial number matches the one on the invoice: a machine without an invoice or a readable serial number may be stolen. Also, inquire about any parts that have been changed or modified, and by whom.
Regarding the warranty, the difference is significant. When purchased from a private individual, a used item is only covered by the warranty for hidden defects, according to service-public.gouv.fr: the buyer must prove that the defect was hidden and existed at the time of the sale. When purchased from a professional, it also benefits from the legal guarantee of conformity. See our guide on warranty and after-sales service.
2. The battery
This is the most important point, and the most difficult to assess visually. Here are a few simple checks:
- Appearance: No warped, swollen, damaged, or open battery casings. A swollen battery is dangerous: do not purchase it.
- Performance under load: During testing, the battery charge indicator should not drop with each acceleration and then return to normal when stopped. A sudden drop indicates worn-out cells.
- Range/Battery Life: Ask the seller how many kilometers the scooter actually travels on a single charge, and compare that to the advertised range for a new scooter.
- The connected BMS (Battery Management System): If the battery has one, the application displays the voltage of each cell group. Significant differences between groups indicate an imbalance.
A worn-out battery needs to be replaced (we manufacture batteries for many models, see our electric scooter batteries), but this cost is deducted from the price. See our guide on battery lifespan.
3. The Steering System
On most powerful electric scooters, the folding column develops play over time. To detect this: with the scooter stopped, apply the front brake, and push and pull the front handlebars back and forth. A clicking sound or movement between the handlebars and the deck indicates play in the folding mechanism or the steering bearings. See our guide on steering column play.
4. Brakes, tires, wheels
- Discs: Rotate each wheel and observe the disc as it passes through the caliper. If it wobbles, it is warped.
- Pads: There must be some material remaining. A spongy feel on a hydraulic brake indicates the need for bleeding.
- Tires: Check for wear, cracks, and bulges. Smooth tires should be replaced.
- Wheel bearings: Wheel lifted, no scraping noises or lateral play.
5. Electricity and Electronics
Open anything that opens easily, or ask the seller to do so. A blackened or melted power connector indicates overheating. Rust or white deposits on the deck suggest water damage. Check that the display shows no error codes, that the lights, horn, and modes are functioning, and that both motors are working on a dual-motor configuration.
6. Modifications
An unlocked scooter, with modified controllers or a battery of a different voltage, isn't necessarily bad; it all depends on who did the work. However, it often voids the manufacturer's warranty, and poorly executed modifications can hide fragile wiring. Ask for details about the components installed and have the wiring checked. Remember: on public roads, an electric scooter must remain limited to 25 km/h.
7. The Test
Ride on a parking lot or a quiet road. Accelerate forcefully, brake hard, and turn in both directions. Listen for: clicking sounds from the steering, squeaking from the suspension, or unusual whistling from a motor. If the motor cuts out during acceleration, it indicates a problem with the battery, the Battery Management System (BMS), or the wiring.
Workshop tip
For a machine costing several thousand euros, a pre-purchase inspection at our workshop is a small price to pay considering the risk. Schedule an appointment and come with the seller: our 30-minute labor service is often sufficient for a complete inspection of the steering, brakes, connectors, and battery. After the purchase, follow our maintenance checklist.
Frequently Asked Questions
What is the most expensive part to replace?
On a powerful electric scooter, the battery is by far the most expensive component. Next come the controllers and the motors. That's why the condition of the battery should be a significant factor in any negotiation.
Is it risky to own a machine without proper documentation?
Yes. Without an invoice, you cannot prove the origin of the machine, and the manufacturer's warranty will not be valid. At the very least, check the serial number.
Does a modified electric scooter retain its warranty?
Generally, no: electrical or software modifications not performed by the manufacturer or its authorized network are excluded from commercial warranties.
Is the private seller obligated to provide a warranty?
The product is covered by a warranty against hidden defects. You have two years from the date of discovery of the defect to take legal action, but you must prove the existence of the defect.
Is it possible to have the machine inspected before purchasing it?
Yes, by appointment at our workshop in Lyon. Contact us and specify the model.
