GETTING STARTED

SERFAS E-BIKE OWNER’S MANUAL

The Dash 350W/500W is operated using the control pad on the

handlebars. The control pad is located near the left-hand brake lever.

First, push the power button on the battery to turn on (Fig.1) The

current charge level will be temporarily displayed on the LEDs (4=full,

1=near empty), then one green LED to show the battery is turned on.

Next, press and hold the button on the handlebar controls to turn

on the display (Fig. 2) Display should light up. Now, your e-bike is ready

to ride. To turn o, press and hold for 3 seconds. The battery will

automatically turn o.

The Dash 350W/500W bike oers pedal assist. When using pedal

assist, an electric motor supplements the rider’s own eort. To use the

pedal assist, simply start pedaling, then push the arrow to increase

assist or arrow to decrease pedal assist (Fig.2). 0 is the lowest 5 is

the maximum. Pedal assist will engage at speeds up to 28 MPH (Dash

500) or 20 MPH (Dash 350).

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.

THE MOTOR STOPS WHEN YOU:

1) Stop pedaling 2) Squeeze the brake levers 3) Release the throttle.

Simply begin pedaling again to re-engage the motor.

BATTERY AND CHARGING

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:
