Non-functioning E+ wheels arrive! (Tons of pictures

A fellow ebiker sent me his non-functioning E+ electronics for me to play with! I can't believe his generosity!

He sent everything that was for the E+ bike. The front battery hub, the rear motor, the console, the ebrakes, and all of the various cables. His bike stopped working after the motor started making some odd noises. Separate from that, the console also died. He replaced the console so there is now an extra non-functioning one. I opened the huge package last night and took a lot of photos. Here are some with a link to all of them if you want to see them...

I know what I'll be doing this weekend. Expect more photos of the front battery hub and rear motor opened up. I can't wait to get a look at the insides of an E+ system!

The big box arrives with both front and rear wheels inside. 
 The two wheels extracted.

 Rear motor hub showing the disc brake mount and the connectors

 The two connectors on the rear motor wheel.

The wheels are truly very wide. They measure just over 1.5" wide on the outside.

 They measure just over 1.25" on the inside.

 The freewheel cassette. I need to reattach this somehow!

 The connectors from the ??? (I'm not sure where these go!)

The rat's nest of twist lock wires! I will definitely need to make these stronger and permanent once I get it working.

Here's the data connector going to the rat's nest.

Electrical wire nuts for quick connections.

 6-way Delphi connector

 There are these unused openings on the battery hub at 120° angles from each other. Wonder what they are?

Another detail of the battery spokes and cover screws.

Vent holes and keyed axle of the front hub.

Slight surface scratches.

I'll do a detailed take-apart of the front battery and rear motor shortly. Hopefully this weekend if all goes well.

  1. Here is a link to my inspection of EPLUS motor after 14,000 kilometers/!!!/
    As you can see pristine condition inside that Eplus motor.
    Also Eplus above you got was clearly modified , this 3 pos connector does not belong to EPLUS drive. Modification went obviously wrong.
