Using an electric bike instead of a car is the best way you can reduce
your fuel usage and increase your fitness. They're ideal for commutes
of up to 50km a day and ideal for people from 15 year old to 80 years
old and from 40kg to 120kg. Finding a really good electric bike
conversion kit for your bike can be difficult. We've done a lot of
research and testing and have a great simple systems at very fair
prices that we can send anywhere in the world - though we specialise
in Australia. We're also making some progress towards getting them all
solar-powered and appreciate any help and ideas on this. Please see
our website for lots of information on electric bikes and making them
solar powered - and eventually algae/hydrogen powered. Matt - Solar
Welcome to the forum!
Have you got a kit that gets around the ridiculous 200W power limit in Australia?
I'm thinking along the lines of auto-resetting switch (?latching relay?) that switches batteries from parallel to series.
30Ah @ 40V or 15Ah @ 80V - strictly when on private land, of course!
As soon as the bike stops or is turned off the relay would reset to the 200W default position.
Or have you got a kit that could be adapted that way?
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, www.solarbike.com.au . The
triple walled deep V rim that comes with the motor kit are a good
improvement. Installation took about 1 hour.

How do you explain to a friendly police officer (or not-so-friendly insurer) that your motor has only 200W? Your bike is 2.5 times over the legal limit....
