The lithium manganese batteries used in our high-end electric bikes are one of the most expensive parts on the bike. They represent great technological achievement, giving the light weight, high power feel of our bikes. With proper care, such as keeping them charged, they should last for many years. But because they are expensive, we realize that customers wonder what will happen if or when they need to be replaced.
So, we are going to do something that nobody else in the electric bicycle business does, with a unique warranty policy on the lithium-manganese batteries that come with our bikes. Our original 6 month warranty will remain in effect, where if there is any battery failure in that period due to manufacturing defect, we will replace the battery.
But, on top of that, we will offer an additional pro-rated, 2 year warranty on the lithium batteries*
. That means the batteries will be covered by an unprecedented 2.5 year warranty. So, for example, in the unlikely event that your battery fails after 1.5 years of use, replacement would go as follows. The first 6 months would count as the free replacement period. The subsequent 1 year of use would count as 1/2 of the two year pro-rated warranty period. We would replace your battery at 1/2 the original retail price (as of 5/1/08, $399 is the full retail price). And, at that time, if you want to upgrade to a different type of battery, such as the long-lasting Li-Fe-Po4, we will apply that credit towards purchase of this type of battery.
*The warranty covers manufacturer’s defects, and excludes neglect and abuse of the battery, such as: opening or modification of the bike or battery, discharging the battery further after its low-voltage self protection circuit has been activated, failing to keep the battery charged, intentional short-circuit of the battery, using the bike for offroad and/or stunt riding, using the bike for racing, etc. This warranty is only for Cycle 9 brand electric bikes that will be arriving late May/early June. Other hub motor kits and bikes may have different warranty periods depending on the manufacturer.
