Green Werks Specialized one off etrike and ebike conversions
GW has invested a substantial amount of time and money testing different motors batteries and controllers to find out in real world with out the BS what really performs the best.
GW decided to use the Humble Direct Drive Hub Motor for their power output and simplicity.
All hub motors are not created equal and using the right one makes a big difference in it's hill climbing ability and efficiency for long distance.
Our controllers are sine wave 18 fet programmable they are efficient and run cool under loads
It will handle up to a 100 volts and 100 amps of power
The battery is probably the most important and expensive component of the entire build.
In a nut shell (the battery is everything.)
Many miles of testing has proven that the 52v 24 or 28 amp hour Panasonic GA cell battery
with a 50 amp continuous and 70 amp burst bms is good for about a 60 to 70 mile range on a ebike with 26 inch wheels.
The long range battery is a 72v 30 amp hour Samsung 30Q cell with a 70 amps continuous and 100 amp burst bms,
this will yield a 100 mile range using a 26 inch rear wheel.
When talking about range all of our numbers are based on flat and hilly terrain combined with out peddling
To keep a handle on everything we use the Grin Technologies Cycle Analyst
It is a remarkable tool for setting up and fine tuning everything in the power system
you will be amazed at what you can do with it.
