The EV Sunny Solar electric bike is an odd product. Aside from the fact that a bike doesn't really need an energy saving power system when you have a pair of legs and and a few extra inches of fat to burn, the EV looks, on paper, like a particulary poor realization.
First, it weighs a hefty 75 lbs. Second, the front hub motor puts out 500 watts, which seems a little steep. Using my bad maths and a little algebra, Power (watts) = voltage x current, which means that a standard 12v battery would have to be pumping out 500/12 or 41 amps.
Third, those shiny wheel covers are the solar panels. Could they really pull in enough juice from the sun to shift a 75 lb. bike and its rider? They don't even look like photovoltaic cells.
And did we mention that the EV comes from Thera-P Products, the makers of the Thera-P-Anti-Snoring Cradle Pillow? The bike will cost you $1300, while the standalone converter kit is $800. Both come with a confidence eroding 90 day warrantee.
