gameofbikes: I built the battery myself with A123 20Ah pouch cells. You can find the info on my pack build here: http://www.endless-sphere.com/forums/viewtopic.php?f=14&t=48947 The 12s 36v battery pack cost me about $400 in parts and I guess I got lucky and got good used A123 cell at about $15...

In case you are in need of a programming cable for your Bafang BBS02 middrive unit, here is a quick and dirty solution. You will need a TTL to USB serial cable using the PL2303HX chipset, a female-female jumper wire and some 3mm heat shrink wire wrap. The TTL to USB cable is readily available...

I was wondering about that rubber pad. I had a problem with my rear derailleur cable getting deflected and rubbing on that rubber pad. If I were to butt up the rubber pad to the downtube, it would pinch my cable. So I left a small gap between the pad and the downtube. I thought the rubber pad...

So here are photos of the completed Schwinn e-bike. Some of the Bike stats are as follows 29 lbs Weight of original bike 41 lbs Weight of e-bike with BBS02, rear cargo rack, dual kickstand 16 lbs Weight of 12s 36v 20Ah Lifep04 battery pack 21 lbs Weight of battery in trunk bag with tools 62...

So while I was waiting on the delivery of the BBS02 unit, I viewed the installation videos on california-ebike.com and the Czech girl at https://www.youtube.com/watch?v=Ia8lpz5J1pI. As I said, the installation was fairly easy. I purchased a crank extractor and bottom bracket tool from...

Following is my build of a Schwinn Searcher 1 hybrid/road bike with a Bafang BBS02 500w 36v mid-drive system. The build process was fairly easy thanks to all the helpful info from posters on the various threads here on this forum. So a big thanks to all those who went before me and posted on...

I got the Hub Cone Spanner BT-2919 tool for the Bafang lock rings on Dec. 9th. Ordered it on e-bay on Dec. 1st for $6.36 including shipping from China. It works fine as a spanner wrench for the M33 lock nut but does not work so well with the external lock ring. I finally got it to work on the...

I think I found a tool that will work on both the M33 locknut and outer locknut cover. The measurements look about right for the outer cover. I'm hoping it works since the tool is only about $7 on e-bay from China. I just ordered one so I'll post once I get the tool and test it. I was able...

There is another way to modify the brake switch with existing hydraulic or other brake levers. When I last e-mailed with Paul at em3ev.com earlier this month, he said he was carrying the new brake sensors that work with hydraulic brakes that are plug and play with the BBS02 kits. When I asked...

motomech: Thanks for the tip on fixing the T1220. Hope it's that simple. Worth checking out. At $95 for a new T1220, I think I will seriously consider the portable Cycle Satiator at $300.

I have been using the Thunder 1220 for over a year with good results. I usually bulk charge my 12s 36v 20Ah Lifep04 battery at 3 amps. Voltage differential is usually less than 100mv mainly because I have one cell#4 that charges to a lower voltage than all the other cells. Every 3rd or 4th...

Hello Melbourne. Thanks for the heads up on the AliExpress 11/11 day sale. I was just about to order my Bafang 36v 500w mid-drive from em3ev.com. Paul has been great answering all my questions on that unit and buyers on this forum highly recommend his company. However, I just couldn't pass up...

Thanks for the clarification. Let me try this scenario. Let's say I have a bike with a 48v 500w BBS02 unit powered by a 48v 15Ah battery. I then have an identical bike but with a 36v 500w BBS02 unit and a 36v 20Ah battery. Both batteries put out 720wh. Under the same conditions, how would...
