Hub Motor With High Powerful For Mountain Cross-country Riding



Electric Bicycle Hub Motor Advantages


Hub motors is require little or no maintenance. They are an entirely independent drive system that retain all of their components inside the motor casing, leaving nothing for you to mess with or maintain.

That enclosed system also means there is a lot less to fail. There are two types of hub motors: geared hub motors which have internal planetary gears to reduce the speed of a higher RPM motor, and gearless hub motors, which have no gearing and directly connect the lower RPM motor stator’s axle to the bike. Geared hub motors usually have just one point of weakness: the gears. Over time, a tooth can break off and the reinforced nylon gears will eventually strip.


Gearless hub motors, on the other hand, have zero moving parts aside from their bearings, so there is basically nothing to wear out. As long as they don’t rust out or wear down their bearings, they can pretty much last forever.

Electric bicycle hub motors also help reduce other bike maintenance tasks compared to mid-drive motors. Since they don’t connect to the main pedal drive system, hub motors don’t add any extra stress to your chain or shifters, and don’t cause any of those parts to wear out more quickly. If anything, your chain will probably last longer than a non-electric bike because the hub motor will be doing more work, allowing your chain to often sit idle.


As an independent drive system, hub motors also add redundancy. Since the hub motor and the pedal drive system are completely independent, you can lose one and still get home on the other. Chain breaks while you’re hitting it hard on a trail? Toss the chain in your bag and ride home on just electric power. Hub motor somehow fails? Pedal back. Either way, you’ve got a backup. This can be huge if you’re far from home, especially for older riders or those who use e-biking as a form of rehabilitation.

The weight of a hub motor can both positively and negatively affect the balance of a bike, depending on the circumstances. In some cases, it can be nice to have the weight of a motor farther forward or backward in one of the wheels. This is especially true of e-bikes with rear mounted batteries. In such cases, a front hub motor can redistribute the weight so the center of gravity is still in the center of the bike.

Lastly, hub motors are much cheaper than mid-drives. Hub motor bikes are mass-produced by the hundreds of thousands, perhaps even millions depending on the factory. The same designs have been in constant use for over a decade in some cases. This means that the prices are astoundingly cheap.


The hub motor is equipped with a cassette torque sensor, which is an upgrade of the conventional cassette motor. Its response speed is faster, and the stable power output makes the motor run more smoothly and convenient for control. The powerful torque output makes the motor more powerful, and the superior waterproof function makes the motor suitable for mountain cross-country riding.

1. Q: What is the E-bike motor kit?

A: The kit is designed to transform your standard bicycle(manual pedal power)to an electric-powered by a motor and battery pack.


2. Q: Will the conversion kit fit my bicycle?

A: The conversion was designed to fit 90% of the bicycles, and you can check your bicycle fork(the two metal pieces that attach the wheel to the bicycle) to be sure. You will need at least 100mm for front wheel and 135mm for rear wheel.


3. Q: If my bicycle meet your standard, how can I choose to install front wheel or rear wheel motor?

A: A front hub kit is normally much easier to install than a rear wheel kit since you don't have to worry about gearing or derailers. When riding, the rider can easily see the front wheel and respond quickly to problems such as wheel spinning.

Rear wheel drive has the advantage of better traction which is great for hills and inclines. And because the rear frame dropouts are normally stronger than the front fork dropouts, a rear wheel can handle more torque and increased power.


4. Q: How fast will it go?

A: The speed would be decided by the motor power, controller and battery spec. According to different countries rules, we provide 25km/h for EU and AU market, provide 30km/h for other market.


5. Q: How far can I go on one charge?

This varies depending on usage, your specification will affect the your battery performance and life. And mostly of the battery have a cycle life of more than 700charges.
