Again i make some improvements and i also interesting in how fast the bike actually drive !
So two weeks ago i mount a GPS Watch on the Handle Bar and first time i really measured the top Speed !!
The V-max is 67Km/h and i believe that really fast for this not speed dimensioned for.... 9 to 87 Tooth ´Sprocket transmission´ .
I always believe the Bike´s Vmax is around 45to 50km/h but on street i overtake some small Motorcycles(moped) so I guessed it .
(my new improvements)
3 weeks ago i had some trouble with the new VEC200(speed controlled) (sometime it want work and i dont know why )meantime i try to fix the problem
but i still want to drive so i took the old VEC200(torque controlled) from my E-Chopper.
The Old VEC200 is much better there is more Power on hill drive i also believe that it reach top speed faster and the motor generally spinning faster .
(learning never stops).....it seams to me "torque Control" is much better for drive without gear Box !
And i modify my Charger to 63 Volt (turn a poti inside) before changes happened it was only around 60-61 Volt .
Its unbelievably how 2-3 Volt can make so much distinction !!
*If i would do this project again i would choose the 72 Volt 3kw version not the 48volt .
*the 5 Kw is a little bit heavier and the controller too also the battery,cable etc. must be bigger and heavier .
If 5 kw is the better choose ......!? difficult to say in my Opinion i always drive 50cc or 90cc Gas-Cycle so the 3kw is a good choose to have similar Power .
But if you drive 100cc-125 Cycle before on the track the 5kw or 10kw..... take the bigger one !
*with my e-chopper i drive 45minutes+ and the Motor is a little bit covered in the front and sometimes it getting hot (so in this case the water cooled would be a better option).
With the E-Hispania i drive max 20-25 minutes off-road-track ,the motor get air-stream while i drive it.
The motor gets warmish but not really hot !
in this opinion i would keep the Air cooled motor .
(hope I could help)
And i would take a other Controller Kelly or Sevcon .
