Vehicle2012 Naked ELF 2FR
This is an Organic Transit (OT) ELF 2FR
prototype which never had the distinctive
fairing of the production OT ELF. As with all
Electric Light & Fun (ELF) vehicles, this
includes a bicycle drive train in addition to
the electric bicycle drive.
MotorKelly Brushless DC
600 watt DC motor
DrivetrainSRAM 8 speed internal rear hub shifter in rear wheel with right hand sprocket. Fixed sprocket chain from mid-mounted electric motor to left hand sprocket freewheel on rear wheel.
ControllerKelly Basic
Batteries1 BMZ Custom for OT, 48.00 Volt, Lithium Iron Phosphate
Organic Transit had custom battery packs built for the different configurations over their 2012-2019 production run. This Naked ELF 2FR had one of the original blue plastic packaged 48v@10Ahr packs. This one is still working at about 75% capacity as of 2Q2020! We have a second 48V 6Ahr battery on board for longer rides.
System Voltage48 Volts
Charger Grin Tech Satiator
I replaced the generic 1.5a charger with a
Grin Tech Satiator 8A/48v charger:

Top Speed32 MPH (51 KPH)
As a Class 2 electric bicycle in US, the controller cuts out at 20mph. Pedaling in the highest gear downhill gets us to 32mph. Typical speed is 16mph on flat ground with some pedaling and some electric assist.
Range40 Miles (64 Kilometers)
25 mi is as far as we have ridden the Naked
ELF at a time, with total 16Ahr capacity.
The range is very dependent upon how much and
how hard one pedals and the terrain.
Watt Hours/Mile20 Wh/Mile
This is very dependent upon how much one
pedals and the terrain.
EV Miles
Current: Miles (0 Kilometers)
Seating Capacity2 adults, possible to have 1 adult and 2
children
Curb Weight125 Pounds (56 Kilograms)
Though weighing only 125 lb, this OT Naked
ELF can carry over 500 lb!
Conversion TimeRefurbishing took less than 20 hours. New rear tire, refurbish SRAM controls, small amount of rewiring, and updated battery pack is all the Naked ELF needed! It was languishing in a garage for several years.
Conversion Cost$550: $375 of that for an updated battery
pack.
