It's the technology rather than the supplier which determines battery performance Dirk.

Both eZee and Wisper use the same Lithium-ion manganese type of battery, and the performance will probably be similar.

It's important to compare like with like when assessing bike weight.

The Wisper is without mudguards lights etc, and has less gears, so weight is saved on all of those. It's well suited to shorter riders as it has a compact frame, so may well use less metal in that.

So those things should be born in mind, do you need mudguards and lights, which cost extra on the Wisper, how well does each bike fit you? Do you need a higher quality 8 speed gear system to cope with hills, or the basic quality six speed?

Basically we have two marketing models here, eZee using the one they've used for several years, a complete package, and Wisper, a quite new company using a minimum package model with some of the differences available as extras.
