Specialized ebike etrike conversions
Green Werks New custom one off etrike's 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 Direct Drive Hub Motor for their power output and simplicity.
No gears to shift, It's real simple with a hub motor you either have the right motor to climb hills or you don't
All hub motors are not created equal and using the right one makes a big difference in it's hill climbing ability.
The controllers we use are very efficient and run cool under loads
They can handle up to a 100 volts and 100 amps of power
and still stays cool which means a longer range.
The battery is probably the most important and expensive component of the entire build.
With many miles of testing we have found that the 52v 24 or 28 amp hour Panasonic GA cell
with a 70 amp bms battery is good for about a 60 mile range on a ebike with a 26 inch wheel.
The long range battery is a 72v 30 amp hour Samsung 30Q cell with a 100 amp 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 with out peddling )
To keep a handle on everything we use the Grin Technologies Cycle Analyst
It is a remarkable tool to use for setting up and fine tuning everything in the power system
you will be amazed at what you can do.
