Technical Data
This section provides you with the technical specifi cations for your e-bike.
The Motor and Wheel Assembly
The Smart Bike has a 500 Watt magnetic DC brushless motor on the rear wheel hub. This type of motor has
excellent low-end torque and high effi ciency when working within its range. Note that while the motor is
very quiet, it does produce some noise. Also attached to the rear hub are speed reduction gear and the
speed free clutch.
The Freewheel
The wheels have freewheels, so the e-bike’s drive train is not fi xedly geared. This means that when coasting
or traveling downhill, you can turn off the engine and your e-bike will continue to move without slowing.
This feature will allow you to achieve faster speeds when coasting, moving downhill or moving with the
wind. It will also allow you to conserve electrical power, because you will be able to let to the motor rest
while moving.
The Controller
Daymak pioneered the development of intelligent component control in e-bikes. The “D- Drive” technology
developed by Daymak is the brain of your e-bike. It allows your e-bike to achieve faster acceleration, to climb
steeper hills, and to save energy. In future, it will allow for other ways of recharging your e-bike’s batteries,
such as by using solar or wind power.
The electronic controller is located under the seat assembly. This controller effi ciently regulates the speed
and electronic functions of the bicycle. It allows for stepless speed adjustment, shuts off the motor when
the brakes are activated, has low voltage protection and has fuses to prevent excess current from damaging
the e-bike’s systems.
The Governor
A key component of the controller is the Governor. The Governor regulates the speed of the e-bike. It pre-
vents the motor from assisting riders when the e-bike’s speed surpasses
32 km per hour.
The governor’s primary function is to make sure that the motor functions effi ciently. If the governor is not
functioning, the mileage of the e-bike will be dramatically reduced, and its performance will suff er.
Disabling the governor voids the warranty, and may damage your controller.
This speed limitation to 32 km per hour is required by government regulations. Traveling faster than 32 km
per hour through motor power alone is illegal in Canada and could result in serious fi nes or penalties, unless
your vehicle is insured for liability, is registered and you are licensed to drive.
