Vehicle1999 EVGlobal 24V
Lee Iacocca design bike for EVG. Very sturdy and unusually shaped frame (for example, no seat post tube) with only rear derailleur - which is an issue as I have mounted additional chain rings in front to get a decent gear ratio, but I mostly use a single (largest) gear anyway, so it kind of works.
MotorHeinzmann Permanent Magnet DC
Drivetrain300W rear hub DC motor and usual bike pedals, chain and gears.
Controller 24V
dedicated 24V controller, designed for EVG
Batteries8 20Ah, 32.00 Volt, Lithium-Polymer
4 packs of 4 series LiPoly 10Ah batteries of older (cheaper) chemistry, advertised much higher than the power they have. Capacity wise they are OK though, so with 2 parallel strings of 8 cells the discharge stays under 1C and they do not sag too badly.
System Voltage24 Volts
Top Speed18 MPH (28 KPH)
Faster when pedaling, this is the speed from the 24V DC motor alone (at approx 30V)
Accelerationlifts front wheel up on initial take-off if not all weight is on the bike.
Range20 Miles (32 Kilometers)
Endless range when pedaling it yourself.
Watt Hours/Mile20 Wh/Mile
estimation - most time I pedal the bike so it is hard to estimate the consumption of the motor alone
