As the Hub Motor Turns and the LiPo Fire Burns. Mid Summer e bike project.
I had to return downtown today to drop off paperwork for food stamps finishing up what I started yesterday. Again the 20" bike performed flawlessly climbing State street hill and getting me home. Voltage was at 3.84V per cell and is currently on the charger downstairs charging back to 4.2V.
I was not sure when DSS closed so took a chance and rode it almost all the way down Crane st. hill. The steepest hill in town I think. there was quite a lot of squeaking but the brakes passed the test and slowed the bike down and stopped it close to the bottom.
I have the funds to rebuild the 24" Huffy. I am not ordering the 80T spoke kit but leaving the 56T spoke kit on the 20" back wheel and will be mounting the six SLAs on the triangle rack for 36V@20Ah 750W 2250 rpm and 26 mph respectively. It will be geared about two mph faster than the Currie was with the same motor but the 11T #25 motor and 80T wheel sprocket. The Currie had no problem climbing up State street hill either.
The 24" Huffy currently has the 48V controller. That controller is one that DA recommended I think.I could use the variable controller I got with the built in pot however even though a pot is good for slow sidewalk speeds I actually prefer a thumb throttle over a pot. Better yet I like both and did in fact have both hooked up before with a three wire throttle splitting it off running two wires from a kill switch one to the throttle and one to a pot. The other two wires splitting off into two wires going to the thumb throttle and the pot. I could set the pot to slow speed and engage the throttle to speed up when I wanted to.
I may hook it up that way again but first must order a 36V controller the same make as the 48V one on there now. The next step is finding the soldering iron and solder and soldering the alligator clips to the wires instead of electrical tape. That last run with the Diamondback was a temporary set up as I have had the wire separate from the clips before more than once. They are only good for a few times before they fail. The last step for this build is getting new bearings in the 24" wheel. I may also install rear brakes by installing metal brackets. I think U brakes should work well. This bike will be heavy with six SLAs so it will be better with both front and rear brakes.
Since it is a 24" frame with a 24" tire on the front and 20" on the back with a big fat seat from wall-Mart it will sit higher up than my 20" bikes and be more comfortable to ride. It will be my daily commuter as I can bring the 20" bike upstairs and lock it up down on the front porch.
The 36V 20Ah SLA pack can also run the Schwinn however I will be taking the Schwinn out with Dan's LiPo packs soon to find out what state they are in also. Thanks.

I just ordered two 36V brushed 800W controllers. One is from China and may not get here until the end of August $14 free shipping. The second is being shipped from the US and should be here by the end of the month. I figured as cheap as they are two is better than one anyway so if one burns out like the one I had before I will have a back up.
I thought about it awhile walking to the store and figured I may as well take a chance and order a second 10.0 pack to go with the one I already have but never charged or ran. Unlike the other 8.0 LiPos I am running this one came in like that and has sat for at least two months and voltage has not dropped at all.
I will now be able to run the Schwinn as a cargo bike as A LiPo pouch nice and lightweight can go on the back of the rear basket enabling me to fill the basket with cargo if I wish. The Schwinn is my 44.4V ride officially now. The 24" bike will be my 36V ride and I am building a third 20" 22.2 or 24V bike with the 500W 24V motor, the 80T #25 sprocket that bolts on the freewheel and that 9T #25 sprocket from electric scooter parts. I have all the parts and gearing will be for 16 mph. Yes I will be mounting the motor with a 2 by 4 or other pieces of wood. :lol: Thanks. LC. out.
