Finished building my 25mph Ebike

[snellemin]

Current setup:

1. 24s2p A123. Sometimes 28S2p A123. Cooler weather 22s1p 5000mah lipo.

2. Magic Pie Golden motor, external controller version. Using 4mm bullet connectors.

3. Lyen 12fet sensorless controller.
Options added at time of order: Cycle Analyst connector, Cruise control connector, USB interface, two voltage setting jumper.

4. Cycle Analyst with external speedo. The current version can handle higher voltage and saving up for it w/associated controller to handle 26S lipo on the same motor.

5. cruise control interface

6. Half grip twist throttle

7. Added precharge resistor for zero sparks.

8. 9 speed freewheel with the smallest tooth being 11T.

Lipo setup uses ec5 connectors. A123 setup uses ec3 connectors. I got the battery bag at Bicycle Barn and the rear rack at Performance cycle.

I want to have nicer Schwalbe Big Apple tires in the near future.

I got the Cycle Analyst, throttle, cruise control, sensorless controller from Lyen of Endless-sphere.com. He is located in San Fransisco.

Mud guards from Performance cycle and REI.

Hope this helps.
