The idea of electric bike classes was first mentioned in Europe then extensively applied in America.?By the time?we have known that e-MTB of speed less than 32km/h is included into Class 1 e-MTB in America.?We explained the classification methods at How electric bicycles are classified in Europe and America. Besides the classifications of electric bikes,…

People in Europe and America buying an electric mountain bike are for different purpose?than who in Asia. Electric bikes for a large part are used by the young as the traffic tool in China (the globalization factor may affect the riding culture and habit in future), but their multi-purpose performance is the big pro compared…

Cause of failure 4: the drive system of electric mountain bike rub resistance is too big. The elimination method: 1 adjusts the relevant parts of the transmission system so that the flywheel, sprocket and chain are on the same plane to eliminate the axial run out of the sprocket. Trouble cause 5: wheel soft. Troubleshooting…

When you ride an electric mountain bike normally, if you feel the car heavy, electric, pedaling, and slow, we call these phenomena hard riding. As soon as you get more and more tired on an electric bike, it is likely that there are seven reasons for this: Cause of failure 1: insufficient air or jogging…

Whether brushless motor or brushless motor, it is normal to produce some mechanical noise (brushless) or electric magnetic resonance (EMR) during operation. However, if the brushless motor produces abnormal vibration and sound during operation, the power lock should be shut off and overhauled in time. When the electric dirt bike moves backwards, it is normal…

First of all, like the maintenance of ordinary bicycles, the front axle, center shaft, flywheel, chain and other transmission parts of the electric dirt bike should be inspected regularly, wiped and lubricated to prevent the normal use due to rust. The motor does not need to scrub and lubricate itself, but only to the repair…

Fault phenomenon First, let's look at the standard case where the battery voltage drops too fast: put a new battery on an electric mountain bike, and as soon as it moves together, the voltage of the electric car drops very fast. Failure check and treatment of battery voltage drop too fast Check that the display…

If your electric mountain bike has leakage, do the appearance check first, find out the leakage of acid leakage; Then take the lid off to see the impermeable acid leak around the cap valve, and then open the cap valve to observe the flow of electrolyte inside the battery. After the above work has been…

Do not change the charger at will. Use the charger correctly according to the instructions. Before charging, make sure that the charger plug (positive and negative electrode) matches the battery socket of the whole car. It is forbidden to use non-standard and inferior charger to charge the battery so as not to cause unnecessary damage…

The gas in the electric mountain bike tyre is reduced or exhausted in 2-3 days, which is called the chronic air leakage of the tires. Specific failures and troubleshooting methods can be found in the following four points: Failure cause: valve tube rupture or valve tube due to aging soft. Elimination: screw out the pressure…

As a new type of vehicle, electric dirt bike is favored by more and more friends because of the characteristics of environmental protection and energy saving. But a better electric dirt bike is generally not too cheap. Battery is important electric dirt bike. So it's important for most friends to use and maintain an electric…

The chain often falls off the flywheel or sprocket during the normal cycle of an electric mountain bike. This failure is called the drop of the chain If the rear wheel is no longer in position and the chain is still loose, the chain should be cut short and then adjusted. The sprocket, chain and…
