Sunstar Review
Here is a link to an independent review of the Sunstar.
Sunstar e-bike kit reveiw
Crank drive kits have a different perspective compared with hub motor drive kits... Because the motor has all the gears of the bike to run through, this gives i a distinct advantage when it comes to the factor of weight, because if you have a smaller motor working through lots of gears the motor can always be running at it's most efficient, therefore consuming less electricity and conserving weight. Also the motor can be reduced in size because it doesn't have to struggle outside of its peak efficiency zone. The Vivax Assist is a perfect example of a small motor working with a lot of gears. it weighs less than 2 Kg's. This kit weighs 4 Kg's with Sunstar's lightest battery.
This kit can also be de-restricted for off road use, also because the weight of the motor is central the back end is lighter. The low center of gravity with this kit is appreciated too.
The Sunstar SO3+ is very versatile when it come to fitting because it replaces the bottom bracket. It is also has a very quiet motor.
The Sunsar Kit works very nicely with many different folding bikes. Also the battery can be removed instantly by key
There are 3 levels of assistance depending on the amount of help you need on any given day or time of day, this can be chosen by pressing the M (mode) button. There are 3 LED's to indicate the amount of charge remaining in the battery and an on and off buttons at the bottom of the unit.
