Whether you're looking for a high-end ebike or an inexpensive urban commuter, there's one option that is sure to fit your budget and your style: the hub motor. However, there are a few differences between the various motors available on the market.
There are two types of motors available on the market: the wheel hub motor and the mid drive motor. These motors drive the wheel directly, without a gearbox or chain. These motors can deliver a range of torque from 107 horsepower up to a whopping 1,000 Nm.
The wheel hub motor can be used in the front or rear of the bike. The rear wheel motor is quieter than the front wheel, and it offers a more motorcycle-like pushing sensation. This is ideal for city riders, who prefer the feel of riding a rear wheel. However, rear wheel motors have a higher weight than front wheels. This can cause a skidding effect when the bike is ridden on loose dirt roads.
The mid drive motor is used near the pedals. This type of motor can be used in the front or rear of the bike, but it works better in the rear. It can help with weight distribution and help to balance weight.
A front hub motor is easier to install, but it doesn't offer as much power as a rear hub motor. A front hub motor is a bit of a compromise, but it can be used as a backup if your budget won't allow for a more powerful motor.
Rear hub motors are more powerful than front hub motors, but they are also more bulky. A rear hub motor also has more traction. This is especially helpful on rough and off-road terrain, but riders are more likely to pick up road debris with a rear wheel motor.
In addition to rear wheel motors, there are also geared hub motors. These motors are a bit smaller than the direct drive motors, but they spin at high RPM. Regenerative braking is not available with geared motors. Regenerative braking uses the motor to reduce the frequency of brake pad replacements. This can increase range by 3-8%.
