ADDITIONAL TROUBLESHOOTING
Having trouble with your Sinch? Most problems are easy to
correct.
1. Start by making sure you have a charged battery. You
may wish to leave the battery on the charger overnight
to ensure a 100% charge before doing additional
troubleshooting.
2. If the motor of your bike will not engage, or only engages
intermittently, doublecheck the cable connection where
the rear wheel 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 additional slack in the cable, then
re-tighten the clips after you have the motor cable firmly
plugged in.
3. If you bent the derailleur hanger on your Sinch 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 more, they are available on
Aventon.com or at partner bike shops.
4. 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.
