We have a sale good through Dec for the Aotema hub motor kit. It includes everything except the batteries and we throw in a multi-tool and a lock.
Why the Aotema motor is superior:
1. It's sensorless. This increases reliability tremendously. Hall sensor issues account for 90% of failures. Sensored motors have five extra wires coming out of the motor which are very delicate. If you break any of these (fall over, spin axle), you are out of commission as the controller will no longer work. Also the hall sensors in the motor can fail at high temps like going up hills. They are a bitch to repair. Leading motor companies are moving to sensorless designs.
There are only three wires coming from the motor allowing an easier install. Also the wires come out the side of the axle, not the end where they are more noticeable and can be damaged.
2. Name brand. Aotema has been manufacturing quality motors for at least 6 or 7 years now and have been imported in the U.S. for at least 5 years (W.E.)With other kits, you really don't know where the motor is manufactured, and can change over time.
3. Quality. Aotema is a successful company that pays their workers a fair (by China's standards) wage so they produce good work. They have top designers who are at the leading edge. We have had zero, yes 0.0 returns. That's why we have extended the warranty to five years!
4. Smaller size. The torque is virtually the same as motors that are a lot larger. It accomplishes this with huge magnets and a steel band surrounding them, increasing the magnetic flux. This makes your bike more stealthy. If you are a flashy person who likes to show off and attract attention (from law enforcement and thieves among others), then you might be happier with one of the larger motors. Most are painted black, so they really stand out. If you do not want to attract attention, and would like the option of riding on sidewalks and on the beautiful trails in state/federal parks, then you will want the Aotema. Most people think it's a large brake.
