Ok... if we are encouraging it...
My first ebike went 45MPH out of the gate because I did my research. I bought it as a kit and modified it.
Nothing but a cruiser bike with 4pcs 6S 4.5Ah in series (original plane white shrink Hobby City packs, no markings)
No BMS, No special charger - bulk charged with a supply.
Motor was an old Crystalyte 5405 (the lower KV)
Controller was standard Crystalyte 12 fet - but I swapped the fets and changed LVC
Brakes were PEDAL BRAKES
Know what? Went 45MPH...
Accelerated hard
Then I took a long journey
Added a drum brake to the front
Welded bosses and added a V-Brake to the front
Bought full face helmet, Jacket, gloves
Doubled the battery
Started bumping current limits further - got into Kelly controllers
Twisted the axle out of the shaft of the motor...
Discovered that I need suspension and lots of it
Big tires with a strong bead
Disk brakes - large - front and rear
Bright lights
In the end... what folks are talking about is building a light weight motorbike.
Industry capped ebikes at bicycle limits. This was stupid.
I would cap them at 35MPH and as much thrust as you can handle (no power limit).
Over 35MPH what you have is a Moped or Motorcycle or some other device which can destroy your body in surprisingly subtle ways.
As far as regulation goes... in the US there are 20,000 laws on the books... JUST FOR GUNS.
That's just guns... not everything else... so - what I propose is that its time for a clean sweep.... or a timer starts on every single law such that it takes a lot of work to keep it in place.
How did I get off on that rant?
