Electric Bikes

Electric bike components

Motors

Electric bicycles can be built with various

types of motors, which differ in strength,
effi ciency, rotational speed, mounting loca-
tion, and other factors.

Electric motors are generally mounted

on bicycles in one of 3 locations: the front
wheel, the rear wheel, or centrally on the
seat tube or around the bottom bracket.

Hub motors

Most wheel-mounted motors are hub-

type motors. These motors sit in the center
of the front or rear wheel, and drive that
wheel directly. The hub motor’s axle is held

fi xed in either the front or rear dropouts,
and its shell is spun by internal electronics.

The rotation of a hub motor is independent

of any bicycle drivetrain components, like
the cranks, derailleur, or cassette.

Most electric bikes use rear hub motors,

meaning the motor is contained in the rear
wheel. This confi guration usually gives the
best handling characteristics, which means
the bike is easier to control; in some cases,
however, a front hub motor is preferable
for a given application.

Hub motors are further classifi ed by

whether they are gearless (direct drive),
or geared. Geared motors are built with
internal planetary reduction gearing. They
give high torque at low speeds, and free-
wheel without any drag. Gearless motors
generally reach higher speeds than geared

motors, are quieter (some are completely
silent), can be rated for higher wattage, and
are capable of regenerative braking (see

“Does it charge the battery when I pedal?”

on page 43). They also produce less
torque, especially at low speed, and have
some inherent drag when freewheeling.

Center drive motors

Centrally mounted motors which add

power to the bike’s normal drivetrain by
driving the chainwheel are growing in popu-
larity. These “center drive” systems are ideal
for off-road applications because of their
high torque, as well as other factors. For

example, in full-suspension bikes, a cen-
ter drive motor greatly reduces unsprung

weight when compared to a hub motor.

Because they integrate with the bicy-

cle’s standard drivetrain, center drive
motors usually require more interaction
from the rider than a hub motor does. The
rider must shift the bicycle’s chain into the
proper position for a given situation: high
gear for speed, low gear for torque. This
extra effort is paid back by a system that
is able to excel in a wide variety of terrains.

Motor power

Electric bike motors are generally clas-

sifi ed by wattage and torque. Watts are a
measurement of the capacity of the motor
to do work. A motor that is consuming
more watts feels more powerful and usu-
ally reaches higher speeds, but drains the
battery faster. Torque is measured in New-
ton-meters and is a measurement of the
rotating force produced by the motor. This
