After Each Ride
1.
Clean and inspect the MDV. Hose off (Use a shower mode or light spray, avoid powerful spray
settings) or wipe down the MDV and dry it with a towel. Look for any damage to the frame or
components that may need maintenance.
2.
Wipe and lubricate the chain. Depending on the riding environment apply a dry or wet lubricant
after wiping the chain clean and dry. We use brands like Boeshield T-9 and White Lightning;
there are others with similar reputations available worldwide on line.
Maintenance
–
every 500 miles or six months
1.
ALWAYS check the integrity of the battery case and battery system. Make sure the battery
padding isn’t worn, or the battery is moving inside the main battery case or the Range Doubler
case.
2.
Check spokes on all three wheels. The electric 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.
Service your brakes and brake pads. Bicycle stores have equipment to bleed the hydraulic
system and replace the mineral oil. They can also replace the brake pads. If you want to do it
yourself, you can find out how to do these replacements on Youtube and order the components
for the service online or through Rungu.
