Why is there no response when twisting the electric bike throttle?

You can prop up the bike. Rotate the rear wheel to check for noticeable resistance. If there is resistance, it can be determined that the controller or motor is faulty, and you need to visit an after-sales service or repair shop for repairs. Below are some precautions for using an electric bike: Regular Charging: Generally, the battery starts discharging after leaving the factory. If unused for one or two months, the battery will be completely drained. Over time, this will reduce battery performance and range. Therefore, even if not in use, charge the battery every half month to one month. Fully Charge Before Use: Many owners often forget to charge after use, forcing them to rely on fast charging when in urgent need. While one fast charge may not have a significant impact, frequent use can create poor memory in the battery, making it unable to fully charge in the future, affecting range and lifespan. Simply put, a fully charged standard battery can run for about thirty kilometers, whereas fast charging may reduce the range to just over ten kilometers. Frequent use of fast charging can negatively impact battery performance and shorten its lifespan.

Last time my electric bike's handle didn't respond when twisted, which was quite frustrating. Usually, it's a battery issue—either insufficient charge or protection mode preventing startup. Check the dashboard display. If it's out of power, try charging it; battery aging is also common, and replacement is needed if it's reached its lifespan. Another possibility is a controller malfunction, which manages motor response—if broken, the handle won't twist. During inspection, check if the electric lights turn on and listen for unusual noises. Loose wiring can also be the culprit, such as corroded lines or loose connections disrupting current flow. It's advisable to first check if the plugs are secure; if not, consider disassembling for adjustment or visit a professional repair shop. Avoid forcing the handle to prevent further damage. Safety is crucial—if this happens while riding, pull over immediately to avoid accidents.

I've encountered this issue several times, mostly due to faulty handlebar sensors. The electric bike's handlebars contain small components that detect twisting force, which can fail from drops, impacts, or moisture exposure. You'll notice the handle feels loose with no feedback when turning. First check externally - gently wiggle the handlebar to rule out jamming. Then test other functions like the horn - if it works, it's a localized issue; otherwise there's complete system failure. Loose battery connections or blown fuses are also common, especially after rain. The fuse box is usually under the seat - locate it using the manual. Avoid tampering with electrical components yourself due to shock risk. Clean the bike before taking it for inspection to prevent dirt ingress and prolong part lifespan. Professional workshops can diagnose this quickly and accurately.

The electric bike handle isn't responding? I suspect it's a control circuit bug. The controller module is responsible for transmitting finger commands to the motor. Once it's burnt out or has a software bug, no matter how much you twist, there won't be a response. Check the dashboard for error codes, or try restarting the bike several times. It could also be a low-voltage protection—automatic lock function when the battery is below half, just wait until it's fully charged. Avoid parking in damp places as the risk of circuit shorting is high. If the system has been modified, it's more prone to failure; prioritize using original factory parts. Avoid overloading and sudden acceleration in daily use, as these stresses can accelerate component aging. For simple diagnostics, connect to the bike's app via Bluetooth on your phone and check the log information for clues. If that doesn't work, seek after-sales service to save time.
