The 2011 GIANT CROSS CITY 4 is a sporty, fast and comfortable
bicycle that is ideal for electrical conversion. The quality running
gear, good price and chromoly steel forks make it an excellent choice
for a very fast transportation machine. This model pictured here I
converted using a 500W motor and a 36V 10Ah lithium ion battery
(LiFePO4) that comes in a custom designed lockable double layered rear
rack. It offers a speed of about 35km/h and a range of approximately
30km with light pedalling. The bike retails in many shops for around
$600. The kit is $890 through Solar Bike, Solar Powered Electric Bikes . The
triple walled deep V rim that comes with the motor kit are a good
improvement. Installation took about 1 hour.

Hybrid System to Solar Charge an Electric Bicycle Video

There are a few different ways to solar charge an electric bicycle but
this is probably my favourite system; I can use one 48V panel through
a custom regulator to go straight to a lithium ion battery or else I
can use the same panel to charge a battery bank to store the energy
and then use an inverter and the normal battery charger for the bike
battery. I've made a short video to show how to do this and put it on
youtube. You can also access it through my Solar Bike website -
