|Location||Las Vegas, Nevada US map|
|Vehicle||2008 Caddie Up |
This is a Chinese-brand folding bicycle (20 inch).
|Motor||Unite Motor MY1016, 350 Watt, 2750 Max RPM,19.2 Max Amp Permanent Magnet DC|
|Drivetrain||Friction Drive. I have a 2 inch diameter roller attached to the motor, which gives an overall ratio of 10:1. This seems to be a good compromise between speed and torque. The roller was made from using a BMX axel peg and then JB Welding a 1 1/4 gavanized coupling pipe around it in order to increase the gear ratio. So far the JB Weld seems to be holding!|
No controller. Just a simple on/off switch.
|Batteries||2 Universal Batteries 18 Amp, 12.00 Volt, Lead-Acid, AGM|
|System Voltage||24 Volts|
|Charger||Schumacher 6 amp|
|Heater||Las Vegas desert heat is enough!|
|Instrumentation||I have a wireless speedometer to measure my speed.|
|Top Speed||20 MPH (32 KPH)|
This top speed can be reached by going down a slight incline. Normal cruising speed on the flat with a 200 pound rider is around 15 mph. Up a slight incline it will go around 10 mph, but usually I pedal with the motor so it doesn't drain down the batteries.
|Acceleration||I usually pedal up to about 15 mph and then turn on the motor. I can get up to 15 mph in a few seconds.|
|Range||14 Miles (22 Kilometers)|
This range would be for flat conditions. Any inclines or wind and the range will be decreased.
|Curb Weight||67 Pounds (30 Kilograms)|
The batteries and controller alone were 26 pounds.
|Tires||20 x 1.75. I have a Cruiser Tire on the front and back.|
|Conversion Time||3 months (working a few hours here and there when I have time)|
|Conversion Cost||$300 (See comments for price break-down.)|
|Here is a breakdown of my costs:|
Folding bicycle on Ebay: $105
Batteries, Charger: $70
Motor (350W) $50
Controller (350W, 24V) $20
Misc. Parts and Tools $55
The motor can pivot and can be lifted on and off the rear tire. When I don't want to use the motor I can lift it up with a bungee cord and then let it down on the tire when I want to use it. The motor's torque will apply pressure to the back tire when engaged.
My controller stopped working so now I just have a simple on/off switch.
NOTE: My current YouTube video is for my old set-up. I will be updating this soon.
