| Batteries
Our lifestyle and e-bike road range
of products all use deep discharge battery packs,
that are specially designed for high current drain
applications. All of the e-bike range and the UM70
have detachable batteries for ease of charging. One
of the decisions you make when you buy an electric
bike or electric powered motorcycle is what kind of battery you should opt
for. Different kinds of batteries have different performance
characteristics and costs to own and operate.
How far can an electric
bike go on one charge?
Similar to conventionally
fuelled cars, EV range depends on a lot of factors:
model, weather, terrain and road conditions, and driving
style. The range in Urban Mover’s electric bikes
can vary from 20 – 60 km from each charge dependant
on the model.
Do I have to worry about
a battery 'memory' loss?
No. The "memory loss"
that you've noticed with batteries for some consumer
electronics (laptops, cellular phones, etc.) is usually
associated with nickel-cadmium (NiCad) batteries.
Electric bike batteries don't have this problem, whether
they're lead-acid, nickel-metal-hydride, or lithium-based.
You can recharge an EV whenever you want, for however
long you want, and it generally won't affect the batteries
storage capacity - no matter what charge level they're
at when you start.
