Hybrid Electric Bicycles

No, I don't recall the brand but his batteries were in an oversized frame. At least that was what his wife said when Ed couldn't find an obvious battery pack. It seemed to be a good choice for Ed's B-Day present and Ed let her turn the water fountain on for the big occasion.

 

Ours too!

I'm hoping my wife will start using it to get out and about the neighborhood. She needs knee replacement but getting out and about will help. It will also be a good addition to her RV.

Do you have a picture of the bike?

 

Here is ours:

I didn't see how they attached. There is a pin for the brake handles and another clamp for the light controls and throttle. I agree the rear view mirrors would be very useful but I just didn't see how they were supposed to attach.

IMHO, the 'Owner's Manual' is a bit sparse on details. I understand the original may be written in Chinese but having an illustrated parts break-down and schematic would be very useful. I feel like I need to take it apart and make my own documentation.

Overall, I'm not impressed with the instrumentation and technical data. There is no speedometer; no odometer; the battery charge level indicator has no engineering units; and no motor or electronics temperature. Also, when I brake, I feel a 'clunk' suggesting something is not as tight as it needs to be.

Still, it worked quite nicely on Sunday. Monday morning I had to pickup some stuff at Krogers, a mile away, and it worked perfectly for this short trip. In the past, I might have driven a 3,000 lb car over and back and now it is just the ebike and the dog on a leash.

I also see this as potentially a test rig for some of my refurbished, NHW11 batteries and other things I'm curious about.

Excellent! BTW, I submitted my request to join the Yahoo group.

I would like to suggest we see if Jim would join. If he could post some of his technical materials there, we would all benefit.

When I get home, I plan to look carefully at the rear fender clearance with the rear tire. I hadn't noticed it until looking at the photos but it sure looks close. I didn't hear any rubbing but that doesn't really tell us anything.

As for vehicle instrumentation, this is something I enjoy doing. I'll try to build a couple of units and share what I put together.

Do you have any sort of laptop or portable electronics device (aka., PDA or otherwise?) For engineering studies, I tend to use a Macintosh laptop, which is not really the right type of 'operational display' unit. But I have some ideas for a microprocessor and an ordinary bicycle and electronic speedometer(s).

Once we get the Yahoo group going, we can collaborate without 'hijacking' a PriusChat thread.

So far, I tend not to pedal. The control electronics detects pedal motion and that triggers and extra surge of power to the motor. So if you were laboring up a hill, it would provide some extra 'ommph' to reach the top.

I did have one strange case of riding back and noticing it seemed to be 'full on.' Apparently the pedals were 'turning' because I didn't have me feet on them as I was going down the road. The pedal motion triggered the extra ommph and it felt like it wanted to 'run away.' It took me two blocks to figure it out and hold the pedals motionless. When you apply the brakes, it cuts power 'RIGHT THEN.'

Just one of those weird things.
