APPENDIX C
The lifespan of your Ebike and its components
1. Nothing Lasts Forever, Including Your Ebike.
When the useful life of your Ebike or its components is over, continued use is hazardous.
Every Ebike and its component parts have a finite, limited useful life. The length of that life will
vary with the construction and materials used in the frame and components; the maintenance
and care the frame and components receive over their life; and the type and amount of use to
which the frame and components are subjected. Use in competitive events, trick riding, ramp
riding, jumping, aggressive riding, riding on severe terrain, riding in severe climates, riding with
heavy loads, commercial activities and other types of non-standard use can dramatically shorten
the life of the frame and components. Any one or a combination of these conditions may result
in an unpredictable failure.
All aspects of use being identical, lightweight Ebikes and their components will usually have a
shorter life than heavier Ebikes and their components. In selecting a lightweight Ebike or
components you are making a tradeoff, favoring the higher performance that comes with lighter
weight over longevity. So, if you choose lightweight, high-performance equipment, be sure to
have it inspected frequently.
You should have your Ebike, and its components checked periodically by your dealer for
indicators of stress and/or potential failure, including cracks, deformation, corrosion,
paint peeling, dents, and any other indicators of potential problems, inappropriate use or abuse.
These are important safety checks and very important to help prevent accidents, bodily injury to
the rider and shortened product life.
2. Perspective
Today’s high-performance Ebikes require frequent and careful inspection and service. In this
Appendix we try to explain some underlying material science basics and how they relate to your
Ebike. We discuss some of the trade-offs made in designing your Ebike and what you can expect
from your Ebike; and we provide important, basic guidelines on how to maintain and inspect it.
We cannot teach you everything you need to know to properly inspect and service your Ebike;
and that is why we repeatedly urge you to take your Ebike to your dealer for professional care
and attention.
