Most new E-bikers don’t care about the details inside the motors that we ride, as long as they just work. But occasionally we use terms in our articles to describe some characteristic about electric motors, and we want our readers to understand why one choice is better than another for a given application. This article is part-1 of a two-part series, with this first part covers the basic terms that are used to describe E-bike motors. Here is what part-1

Sine-wave controllers are starting to get some interest, so we thought some of our readers would like to know what the benefits are, so they can decide if one of these is the right choice for them.

This is an affordable and useful mid drive, if you think you would be happy with 750W…and live where there are hills. Quite a few buyers who have heard about the GNG kits opted for the 1,000W-2,100W  big-brother kit (article about the GNG 1,000W here), that has proven itself to be a very capable and versatile off-roader. The GNG-Gen2 kit featured in this article is listed as the 350W/400W brushless kit depending on which voltage you choose. The GNG 1,000W kit has

There is a recently introduced battery chemistry that we will likely be seeing a lot of soon. Lithium-Nickel-Manganese-Cobalt-Oxide, or LiNiMnCoO2/NMC. Since Asian battery manufacturers have been working on a wide variety of alternative chemistries,

Regenerative braking is very common on electric cars, and rare on electric bikes. Regen means that the electric motor is used to slow you down when stopping and generating electricity which is fed  back into the battery pack which increases your efficiency and increases range. That is how a Prius is able to get almost as good of gas mileage in stop and go traffic around town as it does on the highway.  Obviously, the regen braking system offered on

Common hub motor kits have a simple construction which keeps the price low (especially with Chinese mass-production). The low price and easy installation makes them the big seller by a wide margin.

This is the first in our series of ebike repair stories. Also, replacing the wires going into your motor is a great first step in hotrodding your hub motor since burned wires is the #1 reason for failure in an overvolted overwatted hub motor. (read our hotrodding hub motor story). For an example how effective such a motor can be, one builder/racer modified his $100 9C motor by upgrading to thicker wires and was the first electric bicycle to finish

A torque sensor is a type of throttle that determines how much juice to feed the motor based on how hard the rider is pedaling. This is different from a cadence sensor which measures simply how fast you are pedaling. Cheap cadence sensors are what can be found on most pedal assist system (PAS) bikes on the market today. When done right, a torque sensor can make you feel bionic when you ride your ebike. It allows for a more

The Cycle Analyst is a piece of ebike geek tech created by Electric Bike Guru Justin Lemire Elmore (see our list of most influential people in the Ebike Revolution), the owner of the forum Endless-Sphere and website ebikes.ca. The Cycle Analyst  is the first digital dashboard and battery monitor originally designed around the specific needs of electric bicycles. However, the flexible setup configurations, wide feature range, and affordable price have also led it to widespread appeal in a range of other EV
