They are also more efficient, because they sense how much effort the rider is choosing to give (or HAVING to give, depending on gearing, terrain, etc), and respond accordingly. Torque sensors are less common and more expensive than cadence sensors, but generally regarded as better. Responsive cadence sensors can trigger motor assistance after only a quarter-turn of an e-bike’s cranks, while slower versions take a half or even up to a full turn. These require only that the pedals be moving in order to activate their motor, and as such are less efficient than torque sensors that rely on rider input. Usually, just one type is used at a time, but some e-bikes use a combination of both.Ĭadence sensors are the most common variety used with hub motors. There are two types of sensors used with e-bike motors: either torque or cadence. Direct drive motors are also typically most efficient when operating at high speeds, and so are most often used only on Class 3 (speed pedelec) e-bikes.Īll e-bike motors require input from a sensor in order to provide assistance appropriately. Direct drives are larger and heavier, but are quiet and incredibly long lasting. They are also less expensive.ĭirect drive motors are gearless, and use magnets to turn their shell, which is an essential part of the motor itself. These are the most common type of hub motor, and are typically smaller, lighter, more efficient, and better at climbing hills than direct drive motors. In a nutshell, geared hub motors use a system of internal gears that drive (and turn) the shell of the motor. We have a full article that goes into detail about direct drive and geared hub motors, but a brief mention of their distinctions is appropriate here. Regardless of their placement, hub motors can transfer power to drive their e-bikes in two different ways, and so have two further divisions or sub-categories e-bike hub motors can be either direct drive or geared. The Eunorau Defender S is a rare example of an e-bike with both front and rear hub motors. In this article, focused exclusively on e-bike hub motors, we will dive into the most common manufacturers, discuss some of the best e-bike brands who use their products, and also cover some unique one-offs. The topic of e-bike motors is complex enough that we have a separate guide to mid-drive motors. They are, however, much more expensive, and as such are most commonly found on higher-end models. Mid-drives are also known for their ability to replicate or approach the feel of non-electric bikes. Mid-drive motors, on the other hand, have a reputation for being more efficient and responsive than hub motors – though hub motor technology is improving constantly and coming ever closer to bridging the gap. In fact, you’ll find hub motors on some of the best electric bikes we have had the pleasure of reviewing. They also function well in conjunction with belt drives and internal gear systems that are nearly maintenance-free. Additionally, hub motors are often much lighter than their cousins, and make practical additions to urban e-bikes or folding frames that need to be carried often. We’ll focus on the latter type in this complete guide to e-bike hub motors read on to learn the differences between types of motors, and keep scrolling to examine some of the best hub motors on the market!Īt the present time, electric hub motors are much more affordable than mid-drives, and are subsequently much more prevalent. While mid-drive motors are placed centrally at the bottom bracket and tie into their e-bike’s cranks, hub motors – as their name suggests – are mounted at the center of either the front or rear wheel.
