A. Service Intervals
Some service and maintenance can and should be performed by the owner and require no
special tools or knowledge beyond what is presented in this manual.
The following are examples of the type of service you should perform yourself. All other service,
maintenance and repair should be performed in a properly equipped facility by a qualified Ebike
mechanic using the correct tools and procedures specified by the manufacturer.
1. Break-in Period: Your Ebike will last longer and work better if you break it in before riding it
hard. Control cables and wheel spokes may stretch or “seat” when a new Ebike is first used
and may require readjustment by your dealer. Your Mechanical Safety Check (Section 1.D)
will help you identify some things that need readjustment. But even if everything seems fine
to you, it’s best to take your Ebike back to the dealer for a checkup. Dealers typically suggest
you bring the Ebike in for a 30-day checkup. Another way to judge when it’s time for the first
checkup is to bring the Ebike in after three to five hours of hard off-road use, or about 10 to
15 hours of on-road or more casual off-road use. But if you think something is wrong with
the Ebike, take it to your dealer before riding it again.
2. Before every ride: Mechanical Safety Check (Section 1.D)
3. After every long or hard ride; if the Ebike has been exposed to water or grit; or at least every
100 miles: Clean the Ebike and lightly lubricate the chain’s rollers with a good quality Ebike
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.
4. After every long or hard ride or after every 10 to 20 hours of riding:
• Squeeze the front brake and rock the Ebike forward and back. Everything feel solid?
If you feel a clunk with each forward or backward movement of the Ebike,
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. Feel smooth?
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 Ebike;
then do the same with the other pedal. Anything feel loose? If so, have your dealer check it.
• Take a look at the brake pads. Are they worn or not hitting the wheel rim squarely?
Time to have the dealer adjust or replace them.
• Carefully check the control cables and cable housings. Any rust? Kinks? Fraying?
If so, have your dealer replace them.
• Squeeze each adjoining pair of spokes on either side 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.
