• Clean the bike thoroughly. Do not use a high-pressure cleaner. Use a
bucket of water and gently sponge off any accumulated dirt and salt from
your bike. Dry your Pedelec after cleaning to prevent rusting.
• Lightly lubricate the chain's rollers with a good quality bicycle chain lubricant. Wipe off
excess lubricant with a lint-free cloth. Lubrication is a function of climate. Talk to your Dealer
about the best lubricants and the recommended lubrication frequency for your area.
• Squeeze the front brake and rock the bike forward and back (fig. 14). Does it
feel solid? If you feel a clunk with each forward or backward movement of the
bike, you probably have a loose headset. Have your Dealer check it.

• Lift the front wheel off the ground and swing it from side to side. If you feel any binding or
roughness in the steering, you may have a tight headset. Have your Dealer check it.
• Grab one pedal and rock it toward and away from the centerline of the bike; then do
the same with the other pedal. If anything feels loose, have your Dealer check it.
• Take a look at the brake pads. If they're worn or not hitting the wheel
rim squarely, have the Dealer adjust or replace them.
• Carefully check the control cables and cable housings. If there's any
rust, kinks, or fraying, have your Dealer replace them.
• Squeeze each adjoining pair of spokes on both sides of each wheel between
your thumb and index finger. Do they all feel about the same? If any feel
loose, have your Dealer check the wheel for tension and trueness
• Check the tires for excess wear, cuts or bruises. Have your Dealer replace them if necessary.
• Check the wheel rims for excess wear, dings, dents and scratches.
Consult your Dealer if you see any rim damage.
• Check to make sure that all parts and accessories are still secure, and tighten any that are not.
• Check the frame, particularly in the area around all tube joints and hinges (fig. 15); the
handlebars; the stem; and the seatpost for any deep scratches, cracks or discoloration.
These are signs of stress-caused fatigue and indicate that a part needs to be replaced.
