Types of Ebike Motors:
We currently only offer ebikes with geared hub motors in the rear wheel. This will give you an overview of geared hub motors and how they work in our Roadster V2, CORE-5, 500 Series, 700 Series and LMT'd. We will also cover 2 other common types of motors. The mid-drive and the direct drive hub motor.
Soon (relative term) we will be releasing our Prodigy, a gorgeous Brose mid-drive motor that could not be smoother (Brose designs the motor, controller, display, and all settings for the torque sensor, so it is dialed in!). You can see the internals for this mid-drive below:
Geared hub motors: Provide good low end torque and hill climbing ability. Inside they will have internal gears, bearings, magnets and copper windings as you can see in this stator replacement video. They provide very little resistance, so whether you are coasting or utilizing the PAS or throttle, there will not be any excessive friction slowing you down.
Mid-drive motors: Like the one shown above, these motors have the best hill climbing ability. There are some things to be aware of though, with a mid-drive, it is more critical that you are in the correct gear. You can also cause excessive wear and tear on the chain if riding to aggressively and/or in the wrong gear. Since the chain is used by the mid-drive, if the chain breaks, you will be walking home. Where as hub motors do not use the chain, so you could power home if you still have some juice in your battery.
Direct drive hub motors: These motors are quiet and efficient once at speed and on flat ground. However, they are a little slow to accelerate and do not perform as well on hills. They are often larger and heavier than geared hub motors, however, they are also more robust due to their simple design. Additionally, when coasting or pedaling with the bike off, there will be noticeable drag created by this type of motor. On the flipside, these motors are capable of regenerative breaking (not all have it), but it the battery gains seen as this time are relatively low. Many do not think the trade offs are worth it, you will have to decide what is best for you.
Motor Wattage Ratings
As the ebike industry grows and grows, standards are changing. Many companies used to list the nominal sustained wattage of the motor. Now more and more of them only list the peak and often do not list the brand of motor. Some of the more forthright companies will list the details in the specs, but it might further down and not noticed immediately on the model page where customers often do quick comparisons. We have always strived to provide accurate information and will continue to do so. However, we must follow this trend some larger companies have created. We were reluctant to do so, however, in a quick comparison for customers shopping, we have to share the our specs in the same format that has become the industry standard. In order for proper comparisons to be made, we have simplified our motors rating to be:
500W Shengyi Geared Hub-Motor (350W nominal) for the Roadster V2
750W Shengyi Geared Hub-Motor (500W nominal, 880W peak) for the CORE-5, 500 Series, 700 Series
750W MXUS Geared Hub-Motor (750W nominal, 1000W peak) for the LMT'd
250W Brose German Made TF Sprinter Mid-Drive Motor for the Prodigy
You will notice the new Prodigy has a 250W Mid-Drive motor, but it also has 90nm of Torque. Comparing a mid-drive wattage to a geared hub-motor is not apples to apples. If you want a better understanding of it, make sure you order in advanced this fall: https://ride1up.com/product/prodigy/
Another consideration to take is that whether you have the LMT'd or the 700 Series, 500 Series, Core-5, all bikes will reach 28mph. So while one has more power available or higher wattage sent to the motor, the top speed is still the same.
