I got the 200 22p from this supplier:
I think the Samsung 25r 18650s are now under $3.00. Compared to Hobby King lipos, the 22p sags a lot. I should have gone with the 25r but at $4.50 each (last summer), they were just out of my price range.
Also, my experience is that chargers and power supplies that are packaged well, usually last longer.
Been riding the 500w bike this summer along with my road bike. In two weeks I start work (August 4th) and need to get the 1000w bike working.
I have been having an issue with the 1000w bike. While exerting force on the peddles, the bike was clicking/clacking so loud, joggers were ducking for cover when I rode by. I noticed the crank axel was a little loose, so I tighten it up and it seemed to work for a few miles, then the noise came back even worse. Next, I took the whole crank assembly apart and biked to three different bike shops looking for replacement ball bearings but could not find any. Apparently, they now just sell whole crank units. So a purchased one for $29.00 and put it on the bike. It did not help with the clacking, so I figured it was coming from the rear 6 speed cassette. Here are some photos:
I decided to take the 6 speed cassette off my extra 500w motor and replace the one on my 1000w bike, but could not get it off. The axel is too wide for my tool and banging it with a hammer/screwdriver did not get any movement. I am not a good bike mechanic. I was kind of stuck, however, yesterday while I was dropping supplies at my classroom, I called yescomusa.com to see if they had any 1000w rear kit in stock. Luckily they had one kit and a few minutes later,I picked it up for $230.00 cash. I could have gotten it for $180.00 if I brought the Ebay price/ad with me. This cut into my battery budget so I hope my current pack will last a while.
The new1000w kits are about the same. The controller is a little different along with the paint job. I do not like how visible the "1000W 48V" is etched into the motor.
The freewheel/6 speed cassette seemed stuck to the case. After playing with it for a few minutes, I could see that there was no space between the motor case and the cassette so it could not spin. I decided to file of the paint and some of the aluminum and that did the trick.
Also, I still had to remove the housing/connector, change the washer setup, and add rim tape.
So, I threw the new motor on the 1000w bike (did not replace anything else) and went for a test ride and still had the click/clank sound! I was slightly frustrated
Started playing with the derailer, adjusting the screws, and that seemed to do the trick. The chain looks shot so I plan to replace that and will probably put the old motor back on later.
This summer I cleaned up my balcony and purchased a motorcycle cover on ebay. Our condo association rules prohibit bicycles on balconies so I need a way to hide the bikes. I have been using more than my fair share of the living room with my ebike stuff the last few years.
Speaking of extra stuff. If anyone wants some 26 x 1.75 tires, heavy metal racks, or yescom rack bags, I have been trying to give this stuff away. PM me if you are interested.
My hobby king 25ah pack has been sitting in a tool box for the last 9 months. I opened it up and checked the balance. Its almost the exact same as it was when I stored it 9 months ago.
The bike path is getting more crowed and more bikers recognize my motor (cheating), so I am thinking of a stealthier setup for the future. Maybe a light carbon hybrid bike with a BB02 mid drive. I have a few more years before I can retire and the thought of spending 2 hours a day in traffic is unbearable.
