As the Hub Motor Turns and the LiPo Fire Burns.
I am not sure why one would think that. I went to Doug's again across town approx 4 miles round trip with the cargo bike with the Unite motor on the rear. The LiPos are past their half way point in their life and at 6S or 22V I am only doing about 10 mph top speed now to make them last.
Also since I changed the flat tire at Doug's about 6 weeks ago now there has been a noise where the chain is hitting against something. I think it is the metal bracket. It is no big deal as it still gets me around and probably have close to 100 miles on that build now if not more.
Doug has a 2014 Blue Diamond Back frame he is giving me for $10 for a spare. It has quality brakes on it which he is moving to the Black Diamond Back outlook. You will see that the brakes are adequate for a 27 to 29 mph top speed bike which is all I expect from the 800 watt 36V motor which is going on that bike.
He moved the axle over on that 20" rim so I can attempt to make the 20" bike on my front porch work as the 24V 500W motor and variable controller is already installed. That 9T standard bike chain sprocket DA posted is simply plan B if I can't get the 80T #25 chain and sprocket to work on the front of the 20" bike.
I am NOT Trolling or anything of the sort. I simply don't wish to order any more parts which are wrong and don't work. I don't feel like throwing money away. DA is correct about contacting the company however and the shaft on the motor DA posted does not look like the shaft on the 500W motor I have.
The trolling statement may have been about the cro motor on the front and winch motor on the rear of the 29" bike next summer. It will be a miracle if I can come up with the money for one motor let alone two. However that is at least 6 months away. For the winter time I am just building 20 and 27 mph bikes to make use of the parts and 6S LiPo batteries I currently own instead of just letting them sit around.
My hold up now is money for the few parts I will need. The ol ladies SSA check was held up this month for a week and I paid all the rent and she is reluctant to give me money for electric bike parts when I already have three e bikes running. That and I am looking for a 4K TV and a 22 to 27" monitor for Christmas and will probably be building a gaming machine which will push 4K resolution at 60 frames per second at Doug's house.
Doug plans on upgrading again to Skylake and his stuff is only three months old. He is selling his i5 Devils Canyon with the board and 8 gig ram for $200 and I will be getting a 1050 graphics card and already have a case with full side panel 8)
Also I want to put about $30 on my pirate game. All with a Wall Mart money card that only has $2 and change on it currently. All I really need to get two more e bikes rolling is that 9 tooth sprocket and a new spoke sprocket install kit for that 56T sprocket I am removing from that 29" wheel as I will be getting a stronger sprocket which bolts to where the disk brake goes for the 29" rear wheel sitting on Dougs back porch No type of spoke sprocket would hold up to a 6 HP winch motor as Chalo stated on my other new post refeering it as a rag tag sprocket or something :lol: :lol: That 56T sprocket can then be used for a 500W 20 mph build which it will support as that is what I am riding around on now.
I hope I cleared things up and thanks DA for posting. It has been awhile since I heard from you. LC. out.
see bottom picture below. I think Sunder said that that Magic Pie 5 could handle three times the rated 3 kilowatts. How about 6 kilowatts for each wheel which would be 12 kilowatts total. Maybe that is not enough. 7.5 kilowatts each for a 15 kilowatt All wheel drive bike. 
Thanks.
