This is a quick 8 hour project to tied me over till funds for the float increase. It is called EBaycycle because most of parts come from EBay (bit obvious but it was better than calling it “The bit on the side”). I was given the main bike by a friend all the running gear was brought from EBay all the other bike bits brake cables, pads etc were from a stall at Cornish Market World that were selling all there bike stuff of cheap. I picked up a second donor bike from a recycling centre for £10 it’s a shame the frame is smaller than the main one as it is in better condition.
MotorUnite Motor MY1016 Brushless DC
2500RPM, 250Watt, 14A peak.
DrivetrainDirect drive from motor to second fixed gear on rear wheel. It was 4.2:1 10 tooth on the motor and 42 tooth on the wheel. Now I have redone the entire bike I have used the rear hub and gears I will make them adjustable later. The ratio now is 6.03:1, 42 tooth on the wheel to 13 tooth on the low gear and 28 tooth high gear to 10 tooth on the motor. It works along side the standard pedals and gears so it’s useable as a push bike as well.
ControllerYi Yun Electron 24v 350W
Cheap
Batteries2 7Ah, 12.00 Volt, Lead-Acid, Gel
From a UPS I had lying around. Not my first choice. Makes it a bit back heavy. Come on Lithium-Ion!
System Voltage24 Volts
Charger
For the moment I’m paralleling them up and charging them with a 12V charger also charge at 24V using two 40W solar panels.
InstrumentationWireless Bike Computer
Top Speed25 MPH (40 KPH)
On the first test run I found ones you start it off it will build up speed. I had 24.7 Mph without pedaling on a slight downwards hill. I’m going to alter the gear ratio to try to get more power rather than speed, I need it to help up hill not down. Mk2 not yet tested
AccelerationIt struggles on the flat from standing, starts off at walking pace the slowly builds up. If you start off like you would a normal bike it picks up a lot faster. Mk2 not yet tested
RangeWatch this space still testing
EV Miles
Current:1 Miles (1 Kilometers)
Seating Capacitya adult
Tires26" x 1.75
Conversion Time8 Hour Including repairing the bike. I think it will take longer to tweak it than it did to build it. Mk2 took about 5 hour.
