Over the past 3 years I’ve purchased 3 kits from Solar Bike. The first 2 are always being used by family members. Recently, I decided to build a high power electric bicycle. I had been looking for a downhill frame but then I noticed the Phasor Prototype frame and the fun began. It has a Fox rear shock and Marzocchi forks, with 200mm front and rear travel. The bike produces 4000 watts and the battery has a 1.3 kWh capacity. The 100 volt battery can be charged in 1 hour. The battery was made here in Perth and the charger is a 1500 Watt Elcon charger. With moderate pedalling, I get 60-70 kilometers out of the battery. My commute to work is 46 km, so plenty left in the battery – especially if speed is kept to 30-40kms per hour with some pedalling. I have the controller in a position for airflow and also easy to touch to make sure it’s not too hot. I’ve had this bike up to 88 km/h on a slight downhill. The battery reads 100.8 volts hot off a charge and drops down to 94 volts after a 25km ride. It’s set to cut off at 84 volts for protection.
It wasn’t cheap but it’s awesome and I’m absolutely loving it. I paid the following for all the main parts:
$1500 Dual suspension components
$750 Kit (Motor, controller and throttle)
$2400 Frame (including postage)
