May 1, 2013, written by Ron/Spinningmagnets I haven’t written about the GNG Gen2 drive yet (It’s been out for about a year), because I was waiting to hear about which parts needed upgrading, what the actual performance was, and also because…very few people had bought this kit (so the available info was scarce). 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

The Next Best Ebike Battery for 2013?
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 Brakes on Ebikes
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

DIY non-hub builds, the why and how (part 1)
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.

Replacing or Upgrading Hub Motor Wires
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

Torque Sensors on Electric Bikes
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

Cycle Analyst; Ebike Battery Gauge
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

Adding speed & comfort to your E-bike: the Aerobar edge
Submitted by Larry Hayes ”Deerfencer” As a former road bike devotee partial to 30-40 mile fast touring rides, back in the 1990’s I began experimenting with clip-on style aerobars on my road bike in search of more comfort and speed. The fact is, certain style aerobars can offer as many as three additional hand/arm positions to most road or mountain bikes, so the motivation was there to play with various designs on the market until I found one I was
