Maintenance
–
After strenuous rides, and every 500 miles or six months
1.
ALWAYS check the integrity of the battery case and battery system. Make sure the battery
padding is usable, and each battery is secured well in its case. If you notice wear marks on the
battery casing, use duct tape to cover the wear marks and add padding in the wear area
(packing foam is fine).
2.
Check spokes on all three wheels. The rear wheel often requires more attention due to the
torque of the motor. Spoke and wheel maintenance are part of a normal bicycle maintenance
procedure and will be accelerated with an electric motor. Do not take chances with the spokes
and if you think they are loose, chances are you are correct. The spokes should all have the
same tension. If they are loose, tighten them yourself, or take it to your local bike shop to get
fixed.
3.
Check and replace tires as necessary.
4.
Check all electrical connections making sure that they are all tight. Bad contact means energy is
wasted as heat, which can cause a breakdown of wire insulation. Any wire with melted
insulation indicates a poor connection nearby. Disconnect the batteries and do not operate if
insulation is melted or wire is exposed.
5.
Inspect and lubricate your chain (as described earlier), or if necessary, replace the chain. If you
observe gear changes to take longer than normal, it may be time to replace the chain. Contact
or consult the Internet for the most appropriate replacement chain on
the market at the time.
6.
Inspect the cassette cogs for wear. If you experience chain skip at higher power levels, your
cassette cogs may be worn and require replacement. Contact
, a
qualified bicycle technician, or the Internet on sourcing and exchanging your replacement
cassette.
7.
Service your brakes and brake pads. You can source maintenance supplies from Rungu, but
Bicycle stores also have equipment to bleed the hydraulic system and replace the mineral oil.
The same is true for brake pads. Check the components tab on the Support page of the Rungu
Website to find links to useful maintenance videos appropriate for the Dualie. Standard Bearer
Machines periodically updates these links, if you cannot find information you need send an
