Drivetrain Delerium

I have finally got around to replacing the drivetrain that gibbed, so I can stop constantly playing with the ebikes.ca calculator to pass time (as if I will!), now I have a functional electric scooter at last!
Changes include:

  • New motor (Align 700M 510kv) replacing a perfectly good motor I wrecked!
  • New ESC (Hobbywing 80A HV ESC OPTO)
  • Flange holding the belt onto the wheel
  • Batteries powering the servo tester.

I rode it around my local recreation ground briefly, I found it to have a lot of power (that old classic where you apply too much power and wheelie off the deck!), It handled a dirt track admirably, and it was surprisingly easy to ride once going (though it seemed to get bored with going straight and wished to turn a bit as soon as you applied miniscule control force).
The major problems are the aforementioned acceleration, the deck rattles too much and the controls are both fragile and unpredictable - the handle will need 1/4 of a turn to reach the bottom of the throttle and the handle came off at one point :(

If I were to do this again:

  1. More compact body
  2. Hub motor
  3. Integrated battery and ESC tucked away inside the frame
In short I would build something that I could just kick along whenever the police are nearby and jet off again when they aren't ;)
