In all modes/levels, the drive assist system power reduces
progressively and cuts off as the bike reaches a speed of 25 km/h,
(15.5 mph), or sooner if you stop pedaling. The drive assist re-
engages when speed drops below 25 km/h, (15.5 mph) as long as
the pedals are turning.
Whenever the drive assist system is turned OFF, You can pedal the
bike normally. The drive system will not engage.
Basic Operation of the PedElec
When the system power is ON, power assist is triggered when you
pedal forward. The torque sensor monitors how hard you are
pedaling and the system calculates the amount of assist you need.
The power assistance stops when you stop pedaling (i.e. no torque
is put on the pedals). In other words, power assist happens as long
as you pedal.
When you apply one of the brakes, power assist will automatically
stop, allowing the e-bike to slow down and stop.
Power assist will turn itself off when the e-bike has reached the
maximum speed of 25 km/h.
You should use the gear shifter at the handlebar to set the gears
appropriately according to road conditions and pedal as usual, you
will find that you need to exert a lot less effort.
Power output ratios
(applicable to Japanese version ONLY)
The system provides extra power to assist the rider at startup and
low speed situation (< 10km/h) in a human power to motor power
at a ratio of 1:2.
When the bike is running at a speed higher than 10km/h, the power
assist ratio reduces to 1:1. The power assist will gradually reduce to
1:0 when or before the bike’s speed reaches 25km/h to ensure
safety, which is also conforming to the EU standard.
