The rims are subject to wear which must be checked to ensure they are
intact.
The motorised wheel is also subject to higher stress than a standard
bike wheel, and although it is reinforced, it is possible that spokes may
break. If a spoke breaks, contact your DECATHLON store.
If the bike or battery suffers a fall, check that your battery is intact.
Caution: the watertightness of your battery is no longer guaranteed
following a fall.
