Hi all, as per the title my TSDZ2 has a sporadic fault where it stops allowing me to change the level of assist, and can't switch the VLCD6 off. The motor still works fine but is stuck on the that level of assist. If I turn the battery off and on again its OK and may work fine for a while or...

Hi all, hope you are well, the rocker switch on my battery is basically shot, I leave it on all the time as if I switch it off it can take 50 attempts of switching on and off to get it on. it’s no problem to just leave it on but slightly concerned that it could fail altogether at some point...

Hi all, the switch on my battery is starting to play up and can take 3-4 times switching on and off before it turns on. couple of questions: - if I just leave it in all the time will the battery deplete much overnight or during the day when not in use, I use it every day for a commute. - can...

Hi all, I hope you are well, I've had a TSDZ2 for a few years on an old Trek mountain bike, I use it daily for a 16 mile round trip commute, sometimes pulling a trailer weighing about 20kg. The commute is flat all the way, mainly on a canal path, I'm thinking of changing the donor bike as I...

Hi all, I hope you are well, I converted an old MTB with a TSDZ2 some years ago, use it every day and love it etc. I was thinking about upgrading the donor bike to something with disc brakes and maybe 700c wheels. However all recent hybrid bikes seem to have the cables for rear brake and...

hi all, my TSDZ2 set up has had an increasingly common issue with losing power, it fixes if I wiggle the wires coming out of the battery mount. On closer inspection the issue is one of the wires that comes out of the blade fuse, because of how the fuse sits the wire comes out a 90 degree angle...

Hi all, I was cycling today and the pedal fell off! The thread is completely gone on the crank arm where the pedal screws in, worth noting I have done thousands of miles on the bike and love it so not a complaint about quality. Can I use any crank arm to replace it or does it need to to have a...

Hi all, after browsing the web there seems to be different opinions on the best way to prolong the life of your battery. The two main schools of thought are to either keep it between about 40% & 80% or ensure you always charge to full to 'top off' the batteries. I commute about 16 miles per...

Hi all, any idea what I could have done wrong when changing the blue gear to mean the motor whines really loudly now?! many thanks Neil

Hi all, so I have a TSDZ2 on a mountain bike, 750w, and its all good, love it. I converted the bike so I could put some equipment in a trailer and cycle 7 miles to the beach to go kitesurfing. However I have just got another job which is 8 miles away, mainly flat and I want to cycle the...

Hi all, I converted a bike using the tongsheng and it was amazing, did what I needed to do which was allow me to cycle 7.5m to the beach with a trailer full of equipment. However my parents came to visit on the weekend on my step dad tried it couldn't believe it, he thought his cycling days...

Hi folks, I am looking at two batteries for a tsdz2, one has a continous discharge current of 30a and one of 25a, will this effect the power of the motor at all? thanks!

Hi folks, so I have just fitted the 48v 500w motor to an old mountain bike, with a 48v battery, I am using it to pull a bike trailer with kitesurfing equipment in to the beach. The pull is amazing, even uphill it powers up with a heavy trailer. However I can't seem to get it to go faster than...

Hi Folks, I am looking to get the TSDZ2 48v/500w motor from PSWpower. However I am a little baffled by which battery to get, PSW state the batteries as being suitable for the Bafang TSDZ2 which obviously doesn't exist as a model, I don't know if this means they will work for both Bafang motors...

Hi folks, looking to convert my bike to am ebike for getting to the beach and going kitesurfing. It is about 7 miles each way and nearly all flat. I will need to put about 20kg's of kit into my kids burley bike trailer. Would it be better to use mid drive or hub for this or would the usual...
