What's the advantage of Lithium Ion?

Lithium Ion battery packs provide a much greater power to weight ratio than any other standard electric bike technology around at present. You can expect somewhere between 400-500 discharge/charge cycles from the Lithium Ion battery pack.
However, unlike NiMH or Lead Acid batteries the Li-Ion battery prefers a partial rather than a full discharge.
Please try and avoid full discharges if at all possible. In other words, when you get the bike back from a run, simply plug the bike into the charger until fully charged again.
