Am I asking for trouble? BBS02 on carbon road frame

Hi Guys, I know there's no black and white when building bikes to use in a way they weren't designed to be used, but I am just interested in peoples opinion on this build. I have a 3 year old carbon road frame which I wasn't using as often as I should have been, so I built the bafang on to it to use...

Re: Help with TSDZ2 programming

ound solution!!! Yes Here’s the wiki If the motor is connected to the ebike battery, you don't need it either. A pic of your connector would help.

Wanted TSDZ2 reprogrammed controller 48v 52v

I've failed over and over to flash the opensource firmware on my TSDZ2 and Iam ready to put it in the bin (to get back at it for all the time it stole from me.) Ive got a EM3EV 52v battery so I can't use the motor at all. When I did use it briefly on a friends 48v battery the ridiculously low cadenc...

Re: Help with TSDZ2 programming

Ok, I spent 4 more hours today, I am ready to put this thing in the bin. So I got the TSDZ2 then got a 52 volt battery from em3ev but hadn't thought of the voltage problem. I cant use the motor at all. I flashed the screen, slowly but got there. The motor is impossible; things I've tried: 5 differen...

Re: Help with TSDZ2 programming

Thanks for getting back to us Aquakitty. Potentially my connections are fine but maybe the drivers for the ST link are not correct, or conflicting choice of wires to connect. I did have a similar problem for a long time in flashing the screen, but eventually got there. I am losing hope that this wil...

Re: Help with TSDZ2 programming

Thanks a lot guys. My cable has six wires. Black Brown Orange white green purple Just to be clear its the cable to the motor I opened up, planning to re-soulder inside the motor afterwards. I've taken the motor off of the bike to make the whole fiddly process a bit easier. Aquakitty, your scheme is ...

Re: New build TSDZ2 not working

I had this problem too, confirmed when I fitted the battery on 30 percent charge and it worked fine. Then charged it wouldn't work again. Iam in the process of trying to upgrade the firmware to get around this problem.

Re: The snobby cyclist's noob guide to TSDZ2 & BBS02

Awesome post! Really good info. Just to second that the frame mounting bolt is a really bad idea. I snapped my aluminium cyclo-cross frame on the second ride. I put it down the the flex in the frame when getting out of the saddle (rack mount battery) and climbing 20km mountains in the Pyrenees. In h...

Help with TSDZ2 programming

Really hoping that someone could help me get back on the road with my tsdz2. I installed it and found that the low cadence that it works at is unbearable for me, so started down the route of flashing the open source upgrade, which sounds like it will make this motor work exactly how I need it to. I ...

PLease, what kit do you use, and what is the final bike weight :?: :!: Hi Thierry, The bike is nothing special. Planet X london road, aluminium cyclocross frame, drop bar set up with sram road hydraulic disc. Comfortable enough to ride for a sustained duration in a road racing type position. Settin...

Re: Offer to range test E-Bike kits in the Pyrenees France

I would also be happy to test ebike systems in the sonoran desert. I guess a key difference is that the winner of the Tour de France is frequently decided in my neighborhood. Thats the main reason I mention location. There's a huge untapped market in getting regular road bike enthusiasts to at leas...

Re: Charging dolphin pack with a 5amp charger

Me, I'm charging some of my batteries at slightly over 1A per cell. but they are supposedly Panasonic 26F cells rated for 1.3A. Thanks a lot Docw009, Its some really helpful info. I don't feel much closer to the answer though. Do you think I should try it out, or it's too risky? I only plan to use ...

Re: Offer to range test E-Bike kits in the Pyrenees France

That's true! Its really interesting though, that although the Ebike trend at the moment is interesting for people who wouldn't normally cycle, I think there is space to convert hundreds of thousands of committed cyclists who might be interested in another bike, which provides a different experience....

Offer to range test E-Bike kits in the Pyrenees France

Hi All, I hope that this would be of interest to a retailer or manufacturer. I've been using a cheap generic E-bike conversion kit for about a year now (48V rear hub drive and 13ah battery) I am really interested to regularly ride the most extreme possible distance out of a kit for the pleasure of a...

Re: Charging dolphin pack with a 5amp charger

Thanks a lot for your feedback guys. I've opened the battery to take a look and attached some pictures. The plug looks pretty standard, and the power cables between it and the cells look pretty beefy. It seems that this type of circular plug must be neutral exterior, positive interior, otherwise it ...

Hi All, I have just got into the obsession of Ebikes after 20 years of serious cycling and racing on the road. I love being able to do my 40km commute to work in an hour, and more recently doing 150km and 200km rides, which were getting harder and harder to do on a regular road bike. Problem is, I'v...
