Re: Mobility Trike Build With Coaster Brake

How is it that she can't shift? Maybe a different shifter needed? Yes, there are some out there that might work better for her, but running in low gear gives her more speed than she requires, depending on the PAS level she chooses. She has a hard time controlling her left hand and fingers and has t...

Re: Mobility Trike Build With Coaster Brake

I will try to answer a few comments and questions that have been posted above: I ordered the Coaster Brake Hub with a 3 speed IGH because I did not know exactly how she would use it in practice. Turns out she can not shift on the fly and just uses low gear all the time. I am still glad that I put in...

Mobility Trike Build With Coaster Brake

At 80, I had decided not to do any more electric assist projects, but a little background will help explain why I am doing this one: On Wednesday, August 28, a friend in Eugene that I had converted his tadpole pedal trike to electric assist using a BBS02, introduced me to a friend of his that wanted...

Re: new eZip motor

LC, what Sunder said is correct. If you purchase a 500 Watt kit (motor, controller, throttle, etc.) the 500 Watt rating means that is the continuous Wattage that the system can use without overheating, etc. A good example is my current 48V 750 Watt Bafang BBS02. The controller can be set to any maxi...

Re: Bafang BBSHD and Nuvinci N380 cvt combo-anyone else using this?

My comment about the N171 is efficiency. I put together two TerraTrike tadpoles, a Rover and a Path, both with an auto shift N171 and a brushless hub motor mounted as a Mid-drive chain puller. The auto shift was set up to keep the cadence at the pedals between 60 and 70 RPM. These trikes worked out ...

I personally like dc circuit breakers appropriately rated for your needs, namely 30 amps. Here is an example of one suitable up to 30 amps: https://www.ebay.com/i/252424298342?rt=nc&_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D2%26asc%3D20160908110712%26meid%3Dd05210ffa1824658b68953e46...

Re: new eZip motor

Good price on the breaker, and with free shipping. Should be good for the job based on what the seller wrote. In the first diagram the positive doesn't go to the meter. Probably just a drawing error? Otherwise all three diagrams are identical going from the battery to the controller. Depending on th...

Ok LC, I have edited my previous posts, mostly related to your diagram that labeled the two switches as kill switch 1 and kill switch 2. I think it reads better now and will be less confusing. One thing though, in my experience, even if a controller provides for an on/off power switch the capacitor ...

Re: new eZip motor

I do normally leave my meter running for my entire ride even though I sometimes turn off the power switch which makes the trike inoperative and also turns off some lights that come on automatically when the power switch is turned on.

Re: new eZip motor

To read my comment correctly, I always think of all current flowing from the battery, at least in the case of the positive current. So the word ahead of the meter would mean between the battery and the meter. I do use the DC breaker in place of the fuse since they have the same purpose. Think about ...

Charge at too high a rate at too cold a temperature and you've instantly murdered the pack, rendered it to scrap, unrecoverable. Thanks John.

I understand that you are looking for some special monitoring capabilities, but I have been sold on the Signalab BMS that Ping uses on his batteries. All his batteries are LiFePO4 so his 12s BMS should be perfect for your application. The main reason I like these is the 12 LEDs that all light up whe...

Brad, nice that worked out for you. The problem at low speed that you mentioned is also present in the older BBS02s that worked "properly". I think what happens is right at the point where the throttle takes over for the PAS system there is a very small dead space where the throttle signal...
