The Dash 350W/500W e-bike is equipped with a throttle, which is
mounted near the rider’s left thumb, to propel the bike without
pedaling. To use the throttle, start pedaling (one pedal revolution)
then push down on the throttle while pedaling. Once the bike is
moving on throttle power, you can stop pedaling entirely and use
your thumb to control the speed of the bike. The throttle can propel
you at speeds up to 20 MPH.

BATTERY AND CHARGING
6
SERFAS E-BIKE OWNER’S MANUAL
The Dash 350W/500W uses a Lithium-Ion battery which can be charged
on or o the bike. We recommend charging the battery o the bike
indoors, in moderate temperature conditions. To charge the battery,
plug the charger into the charging port and then connect the charger to
a wall outlet (Fig.3). The LED indicator light will be red when charging
and will turn green when charging is complete. When finished, unplug
the charger from the battery and from the wall outlet.
Take care of the battery to ensure a long service life.
To optimize the performance of the battery over time, try and use it
(discharging and charging) at least monthly. But if you won’t be riding
your Dash 350W/500W for an extended period of time, it’s best to store
the battery fully charged. EVERY 2 MONTHS: Put battery on the
charger to maintain optimum level.
After many charging and discharge cycles, runtime and range will be
reduced. Replacement batteries are available from Serfas to extend the
life of your e-bike. The lifespan of the battery is about 500 charge /
discharge cycles for properly maintained batteries.
When you install the baterry on the Dash 350W/500W, it locks into place
automatically. To unlock for removal, use the supplied key.
DO NOT ride the bicycle if the battery rattles or moves - it should be
firmly attached.
The Dash 350W/500W battery contains a USB port for transmitting
diagnostic data only, not for charging. It will not charge or power devices
via USB.
• Charge and store the battery indoors if possible. The battery
can be removed from the bicycle for this purpose.
• Avoid extreme hot and cold temperatures.
• DO NOT submerge your bike or any of the components in water.
This action will void the warranty.
MAINTENANCE AND SERVICE
SERFAS E-BIKE
• When cleaning your bike, use a damp cloth and gentle dish soap.
NOTE: DO NOT use a pressure washer or sprayer.
• Periodically apply a light lubricant to moving parts, including the
links of the chain, derailleur pivots, and shifter cable inner wire
where it enters the cable housing.
• If you ride in wet / humid environments, clean and dry electric
connections and apply an anti-corrosive.
• Keep tires inflated to their recommend pressure (30-50 PSI /
2.0-3.5 BAR / 200-350 KPA) and check weekly.
• Clean the drivetrain and lubricate the chain (monthly).
All bicycles will need a periodic tune-up or adjustments by a professional.
An annual “check-up” is beneficial. Your bike’s service schedule will
depend on the frequency of its use. In-between expert services at a bike
shop we suggest:
