ADDITIONAL TROUBLESHOOTING
SERFAS E-BIKE
Having trouble with your Dash Plus 500W? Most problems are easy to
correct.
1. Start by making sure you have a charged battery.
2. If the motor of your bike will not engage, or only engages
intermittently, double check the cable connection where the
motor plugs into the rest of the system. This connector
must be firmly and fully plugged in to function correctly. If
necessary, loosen the clips holding the cable to the frame to
create additonal slack in the cable, then re-tighten the clips after
you have the motor cable firmly plugged in.
3. The throttle on the Dash Plus 500W will only engage after the
motor is turned on via pedal assist. This is a safety feature
designed to prevent you from accidentally engaging the throttle
while parking or walking the bike. If you are having difficulty with
the throttle, remember to make one revolution of the pedals
first, then engage the throttle. You can stop pedaling after the
throttle function turns on.
4. If you bent the derailleur hanger on your Dash Plus 500W in a
fall, don’t worry. It’s actually designed to fail, sparing the more
expensive frame, and is inexpensively replaceable for this reason.
If you need another, they are available on www.serfas.com or at
partner bike shops.
5. If your bike powers up normally and shows no error messages,
but will not run when you turn the pedal assist on, check to
ensure the cadence sensor under the left crankarm is plugged in.
