Why is it difficult to push an electric bike backward?

Possible reasons include: Mechanical issues: The "locking" phenomenon caused by mechanical problems in the motor. This could be due to damage to the motor bearings (or the motor magnetic cylinder). Rear brake: Check if the rear brake of the electric bike is locked. Rear wheel anti-theft lock: The rear wheel anti-theft lock might be self-locked or already engaged without being released. Precautions for riding an electric bike Follow traffic signals: First, no matter what type of vehicle, it is essential to follow traffic signals. Even electric bikes should not recklessly run through red lights, as encountering a car that also ignores the signal could result in fatal consequences. Check components: Before riding an electric bike, always ensure that all parts of the bike are safe, especially the brakes. If the brakes are malfunctioning, not only is it easy to be hit by other vehicles on busy roads, but it also increases the risk of colliding with pedestrians. Additionally, encountering steep downhill slopes can easily lead to falls and injuries.
Last time I was pushing my electric car in the parking lot, I found it particularly difficult to push backward, feeling like the wheels were stuck and hard to move. This is mostly due to issues with the braking system, such as the parking brake not being fully released, which can jam the rear wheel bearings and cause a significant increase in resistance. Additionally, low tire pressure can enlarge the contact area, making it feel like dragging a sandbag when pushing. The complex structure of electric cars, such as the regenerative braking system, may generate additional drag when not in motion, especially in winter when low temperatures cause components to contract, making it more prone to such issues. After my inspection, I discovered that the brake pads had aged and stuck to the brake discs. If not addressed promptly, this can wear the tire surface and increase the risk of a blowout. It's best to visit a repair shop as soon as possible to ensure the brakes and tires are functioning properly. Regular maintenance is also essential to avoid such troubles in the future.
As someone who frequently works with electric vehicles, I've encountered the issue of increased resistance when pushing backward several times. The most common culprits are problems with the rear axle or drivetrain, such as rusted and stuck driveshaft components, which cause squeaking noises and a sudden rise in resistance when pushed. Underinflated tires are another pitfall, especially when the rear tire pressure is low, doubling the ground friction and making the vehicle feel heavier. In electric vehicles, a malfunctioning battery management system might cause the electric assist to work in reverse, creating drag instead of assistance. I recommend starting with simple checks: ensure the parking brake is fully released, inflate the tires properly, and then try pushing lightly to see if it feels easier. Don’t underestimate this issue—long-term neglect can wear out suspension components or shorten the motor's lifespan. Addressing it early can save money and ensure safety.
