What Should You Check When Your New E-Bike Arrives?

If you buy a new electric bicycle, can you just unpack it, attach the handlebars and pedals, and ride off right away once it arrives?

We do not recommend doing this. When a new electric bicycle arrives, you should first check for shipping damage, ensure all parts are included, verify that key components are securely installed, confirm that the brakes and tires are functioning properly, and check for any abnormalities in the battery and electrical system. Only after confirming that the bike meets the manufacturer’s assembly requirements should you take it for its first ride.

Electric bicycles purchased online may have been subjected to bumps or vibrations during shipping, and some models require users to complete certain assembly and adjustments. Even if the outer packaging appears undamaged, you cannot assume the bike is safe to ride on the road.

Below is a practical guide for inspecting your new bike upon delivery. It will help you identify any issues before your first ride and determine which situations can be resolved by following the instruction manual and which require contacting the seller or a professional technician.

Inspect the outer packaging for shipping damage

When unpacking, we recommend first taking photos of the outer packaging, shipping labels, and the vehicle’s initial condition. If you notice any damage to the packaging, obvious dents, or loose parts, keep the photos as evidence when contacting the seller or the shipping company.

After removing the electric bicycle from the packaging, perform a general visual inspection, paying close attention to:

• Check the frame for cracks, visible dents, or abnormal bending.
• Check the connection points between the front fork, handlebars, and frame for signs of impact.
• Check the rims for visible deformation.
• Check the brake levers, display, lights, and other protruding parts for damage.
• Check the battery casing, charging port, and related cables for cracks, crushing, or other abnormalities.

If you notice cracks in the frame, severe deformation of the rims, damage to the battery casing, or obvious damage to the cables, do not turn on the power or test ride the bike. Take photos to document the issue, and contact the seller or manufacturer for advice on how to proceed.

Verify the parts and order information

After confirming that the vehicle has no visible damage, check the items in the vehicle against the packing list. Common items include:

• Electric bicycle and components that require separate installation.
• Charger compatible with this model.
• Battery key or other vehicle key (if applicable).
• Pedals, fasteners, and necessary installation tools.

Package contents may vary by brand and model. If any key parts are missing, the charger model does not match, or the model you receive does not match your order, you should contact the seller first. Do not purchase replacement parts on your own if you are unsure whether they are compatible.

Check the handlebars, seat, and folding mechanism

To facilitate transportation, many electric bicycles have their handlebars, seatposts, or other components packaged separately. After assembly, these connections must meet the manufacturer’s specified installation requirements.

First, check that the handlebars are in the correct position, that they turn smoothly, and that the mounting bolts and clamps are secure. Next, check the seatpost height and insertion depth to ensure they do not exceed the minimum insertion line marked on the frame.

If you have purchased a folding electric bicycle, you should also check the frame and handlebar folding latches according to the instruction manual to ensure they are fully closed and that the locking mechanisms are functioning properly.

When tightening bolts, do not simply tighten them as much as you feel is necessary. Over-tightening may damage threads or components; the correct procedure is to follow the manufacturer’s specified torque values and installation steps. If there is noticeable play at the handlebar connection, the latches do not close securely, or you cannot confirm that the assembly is correct, you should stop riding and seek professional assistance.

Check the tires, rims, and wheel fasteners

Tires and wheels directly affect a vehicle’s stability, so they must be inspected before your first ride.

First, check the tires for cuts, bulges, or obvious deformation, and ensure the tire bead is properly seated. Next, inspect the rims for noticeable bending and confirm that the wheels are securely mounted. Adjust the tire pressure according to the permissible range indicated on the tire sidewall, the vehicle manual, and the specific model requirements—do not assume that higher pressure is always better.

Next, gently rotate the wheels to check for noticeable wobble, friction, or unusual resistance. Verify that the axle fasteners are installed correctly according to the manual. If you find that the tire bead is not properly seated, the wheel wobbles noticeably, or the axle is not securely fastened, do not ride the bike; resolve the issue first.

Check the front and rear brakes

The brakes are a critical component that must be checked before your first ride.

With the vehicle powered off and in a stable condition, operate the front and rear brake levers separately to ensure there is no abnormal play, sticking, or bottoming out. While pushing the vehicle, test each brake to confirm that it effectively stops the corresponding wheel from rotating.

You should also check the brake cables or hydraulic lines for visible damage, leaks, or abnormal kinks, and ensure that the brake components are installed correctly.

Please note that the braking feel on a brand-new bike may differ from that of a bike that has already been broken in; however, you should not ignore insufficient braking power or unusual noises on the grounds that “a new bike needs to be broken in.” If the brakes fail to reliably stop the wheels, the levers bottom out, or you detect a leak in the hydraulic system, do not continue riding. Contact the manufacturer or a qualified bicycle technician for inspection and adjustment.

Check the battery, charger, and electrical system

The electrical system of an electric bicycle also requires careful inspection, particularly the battery and charging equipment.

First, check that the battery casing shows no cracks, swelling, fluid leakage, or signs of abnormal heat, and that the battery connectors have no visible damage or moisture. Install the battery according to the instruction manual, and ensure that the locking mechanism works properly so the battery cannot come loose easily.

Next, verify the charger’s model and compatibility requirements to ensure it is the product provided by the manufacturer with the bicycle or one explicitly recommended by the manufacturer. Do not assume that a charger is compatible simply because the plug fits. For the initial charge, use the specified charger, charge under supervision, and avoid charging while sleeping or when unattended.

If the battery exhibits abnormal heat, an unusual odor, swelling, smoke, or other abnormal conditions, do not continue to use or charge it. If there is a risk of smoke or fire, move away from the device and contact local emergency services.

After turning on the power, check the display, lights, and power-assist function.

Only after completing a mechanical inspection and confirming that the battery and cables show no obvious abnormalities should you turn on the power according to the instruction manual.

After turning on the power, you can check the following:

• Check that the display screen turns on correctly and that no error messages appear.
• Check that the battery level indicator is displaying correctly.
• Check that the headlight, taillight, and other lights are functioning properly.
• Check that the assist settings, control buttons, and other controls are responding correctly.
• Check that the brake-activated power cut-off function (if equipped on the model) is operating according to the user manual.

Do not operate the throttle indiscriminately when the wheels are off the ground or the vehicle is unstable, and do not suddenly start the motor in confined indoor spaces. If abnormal error codes appear, the motor starts on its own, the controller malfunctions, or there are issues with the wiring, stop testing immediately and contact the manufacturer or service personnel.

Perform a low-speed test before your first ride

Only after passing all the preceding checks should you consider taking your first ride.

Choose a flat, open area free of traffic and pedestrians, wear a properly fitting helmet, and start in a low-assist gear. Begin by riding at a slow speed—close to walking pace—to get familiar with the bike’s steering, braking, and motor response. Test the feel of both the front and rear brakes to ensure the bike can decelerate and stop smoothly, then gradually familiarize yourself with the other features.

During your first test ride, do not immediately attempt high-speed riding, sharp turns, steep slopes, or carrying passengers or cargo. If you notice handlebar wobble, wheel friction, unusual noises, brake failure, or abnormal motor response, stop riding immediately and inspect the bike.

If you are unsure about assembly, brake adjustment, or testing the electrical system, the safest approach is to have a professional bicycle mechanic perform the inspection rather than attempting to verify the bike’s safety while riding on the road.

Save photos, serial numbers, and warranty information

After completing the inspection, we recommend keeping a record of the frame serial number, purchase order, photos of the delivery, and warranty documents, and documenting any issues found along with how they were resolved.

If the vehicle has shipping damage, missing parts, or malfunctions, contact customer service as soon as possible through the channels specified by the seller. Keeping photos, videos, and communication records will help determine whether the issue is due to shipping damage, an assembly problem, or a product defect.

Some sellers or manufacturers may impose a short deadline for reporting shipping damage, so you should inspect the item as soon as possible after receipt and refer to the order terms and official after-sales policies.

Summary

Once you receive your new electric bicycle, don’t rush to ride it. First, inspect the frame and packaging for damage, as well as the accessories, handlebars and seat, wheels and tires, brakes, battery and charger, and the display and power-assist function. If you find structural damage, brake malfunctions, a damaged battery, or cannot confirm that key components are installed correctly, do not test ride the bike. It is safer to contact the seller, manufacturer, or a professional technician first and use the bike only after the issue has been resolved.

Frequently Asked Questions (FAQ)

What’s the difference between inspecting a new bike yourself and having it inspected by a professional bike shop?

Inspecting the bike yourself is best for verifying the order, parts, and obvious cosmetic damage; a professional bike shop is better suited for confirming that the assembly, torque settings, and brake adjustments are correct.

Buyers can document any packaging damage, check the battery label, and inspect the display on their own, but if they are unfamiliar with the installation of the wheels, stem, or pedals, they should not assume the bike is safe simply because it “looks like it’s assembled.” If you cannot confirm the quality of the installation, you should have a professional technician inspect it.

What is a PDI (Pre-Delivery Inspection) for an electric bicycle? Can buyers perform it themselves?

A PDI is a systematic inspection of the bike’s overall safety condition prior to delivery. Buyers can complete most routine checks using basic tools and a checklist.

A standard PDI includes checking the tightness of mechanical components, testing electrical system connectivity, adjusting brakes and gears, checking tire pressure, and testing battery charge and discharge response. Although professional bike shops have torque wrenches and testing equipment, online buyers can complete most safety checks by following the manual’s instructions and using the tools provided with the bike to perform visual and static inspections of key components. However, for adjustments involving brakes, axles, or the electrical system, it is still recommended to consult a professional technician if you are unsure.

Once your new bike arrives, which issues can you handle on your own, and which ones require contacting customer service?

Minor cosmetic issues, checking the parts list, standard assembly, and basic functionality checks can be handled on your own; however, if you encounter structural damage, brake malfunctions, battery failures, or electrical error codes, you should contact customer service.

For example, issues such as surface scratches, loose screws, or low tire pressure can usually be resolved on your own by following the instruction manual. However, if you discover a cracked frame, a deformed front fork, brakes that fail to stop effectively, a bulging battery or unusual odor, a motor that starts on its own, or an error message on the display, you should not attempt to disassemble or repair the bike yourself. Instead, stop using it immediately and contact the seller or manufacturer.

Under what circumstances must you stop using the bike and refrain from test riding it?

Do not test ride the bike if there are suspected cracks in the frame or front fork, if the wheels are not securely fastened, if the brakes do not function effectively, or if the battery or charger is damaged or exhibiting abnormal behavior.

In addition, you should immediately stop using the bike if you experience uncontrollable power output, obvious electrical malfunctions, or if the folding mechanism fails to lock securely. Safety-related issues should not be addressed with a “let’s just ride it and see” attitude; instead, resolve the problem first or seek professional assistance.
