Woosh starts shipping Tongsheng TSDZ8 with 250W label

Featured Replies

Hi [mention=6303]Woosh[/mention] - back in your first post in this thread you said -

Gone is the anti-torque hanger on the TSDZ2B.
- why is the anti-torque hanger no longer need (that's really good new BTW) - is the 'triangular' retaining clamp more serrated than the one for the TSDZ2?

 

And can you tell me what is the gap between the crank axle housing and the main motor body (see pics below). On the TSDZ2 I estimate it is roughly 6.5mm at point 'X' and this is what it makes it a really tight for some frame/BB combinations.

 

The final mounting position of the motor looks to be 'swung forward' much more than the TSDZ2 and more like the Bafang BBxxx series and I wondering if the TSDZ8 might work with one of my bikes that has an eccentric BB - any thought? (and @Az - maybe you're in a position to answer some of the above?).

 

Thanks both.

yes.

On the TSDZ8, it's about 11mm-12mm.

Yes.

Still not. Search the net if someone has managed to fit an BBS01 to your bike. If there is, then you'll be OK because both have the same footprint.

Gap is around 1cm, but it is not only gap that has improved. Also the way how bracket is attached to motor.

I can run all cables I need between motor and BB. To install TSDZ2B I had to open the case, slide motor into BB and then close case. TSDZ8 I can just slide in. Big improvement.

I have just been doing a bit of off road and have realised that when you get to more technical bits, the Bafang BBS (on a Boardman 29er pro) has a bit of a disadvantage : if you are pedalling delicately a fine line on a slow section, then the cadence sensor kicks in and gives you a big dollop of power which rather ruins your finesse and gives you a bit of a scare if there was big drops on either side ! I wonder if the TSDZ8 would be an improvement - it just varies the power depending on the pedalling effort.

I was thinking I could get a full suspension bike and add a TSDZ8 if that is sensible, does it make the conversion complicated ?(apart from having room for the battery) - was the max current 15 amps on the Woosh version ? I could maybe change the tyres and used the Boardman / BBS as a road bike.

This guy had BBS02B before. Interestingly he says Bafang gear sensor works on TSDZ8.

that's interesting - I wondered if I could just ease off on the pedalling effort when I do a gear change it would reduce the power

Theoretically it should. I don't have any problems with gear changing on TSDZ2B, but it is installed on step through bike. MTB is a different story, so Bafang gear change sensor might be something to consider.

Hi there, is your offer still running for this motor at £329, if so I'll buy one today.

Thanks.

Please talk to Andy, he'll be back at 1pm.

Battery which I ordered over a month ago arrived yesterday, so today in the morning I converted my MTB and took it for a short test ride.

I recommend you buy this motor, install and don't look back. I am really impressed with performance. Much smoother power delivery comparing to TSDZ2B.

Trust me, you won't regret buying it.

Once converted my old MTB is back in action. I missed it so much. Now I can ride proper downhill again. I might end up in hospital bed next to Soundwave ;)

I really like TSDZ8. It is quiet and has plenty of power to offer.

Edited by Az.

Can the restriction be removed in the settings?

Void warranty though I know.

I have another bike I want to convert for off road. I was thinking if this motor can be unrestricted for that purpose, plus restrict for road use as a backup it would be perfect.

What restriction do you have in mind?

 

As per power, this motor offers plenty out of the box. At fully charged battery it is 54V x 16A = 864W of input power. Much more than I need, so didn't even try to alter it.

 

As per speed I didn't install speed restriction in the first place (yet), so don't feel the need to derestrict it LOL

Edited by Az.

Thinking about it, I guess the speed is based on your bike gearing with centre drives.

So how is it restricted to 15mph?

Something I've not considered.

I guess the controller monitors the magnet on wheel spokes and cuts power at 15mph?

I'm glad to see that the TSDZ8 is working well for you and I look forward to hearing how the motor performs over time and you've some serious miles 'on the clock'.

 

..... Much smoother power delivery comparing to TSDZ2B.

I regularly ride each of my two TSDZ2 bikes (both OSF) and find power delivery is smooth too and I can't imagine what 'smoother' power delivery would be like. Are you able to expand on your observation please?

 

Oh, and does the TSDZ8 take OSF?

 

Thanks, .

I was referring to TSDZ2B without any software modification. This is probably why you have different experience. Seneagle described similar feeling in his thread:

 

"There is a slight surge from the torque sensor. You can feel a threshold of pedal pressure that steps up the power. It's not a linear relationship. That's not so noticeable on other torque sensor systems that I've tried. The disadvantage is that you can feel the power switching up and down when you think you're pedalling constantly at constant speed. The advantage is that you can easily step up the power, probably to maximum, by pedalling a bit harder. "

I don't know if you can modify TSDZ8 software. I simply don't feel that need, so didn't explore subject. I have seen somewhere people saying that TSDZ8 is performing like TSDZ2 with OSF.

 

Together with my son we went on a trip to have some proper off-road experience. Motor performed brilliantly. It is exactly what I need.

 

One minor thing - brake sensors are essential. For some reason Woosh ships motor with cable breaks sensors. Who is still using cable brakes?

 

Woosh - there is a room for improvement there. Please include proper sensors.

Hydraulic brake sensors for tsdz are available but not from tongsheng. Just ask Andy. I buy stuff only from factories.

I didn't see them in your shop. Perhaps I should have asked Andy.

My point is it would be nice to have them in the box without asking. Just a suggestion as I know you like to go extra mile for your customers.

 

BTW do you know what displays accept sensor brakes? VLCD5 is huge, I would prefer something much smaller.

I can see your point. I don't like us to be involved with more items to support especially when they are not made by Tongsheng or Bafang.

Will ask Andy what he wants to do.

Thanks for clarifying all of that.

 

Given how successful OSF has been in improving the ride for the TSDZ2 , it would be daft if Tong Sheng didn't incorporate some of the better features into the TSDZ8.

 

If that is the case and from your experience that seems to be highly likely, then that is brilliant as faffing around with getting OSF installed is not straight forward and has defeated many.

 

One minor thing - brake sensors are essential.

 

Why do you say that?

 

On my TSDZ2 the power delivery stops almost immediate (the chain ring does continue to rotate maybe half a dozen chain links after pedalling stops, but there is no power/thrust in what I'd term residual rotation. In fact it is a good 'feature' in that sometimes I wonder if power has cut out (I ride exclusively in ECO mode) and so to check, I look for the residual rotation to make sure all is well.)

 

Sometimes (rarely) the software has a clitch and the motor will run continuously without pedalling, but there is little power delivery to the chain ring when this happens and the bike can be stopped with light brake pressure whilst you power OFF/ON. This also happens on my wife's TSDZ2 and that one is running stock firmware.

I use cable brakes and they stop fine! As this is a conversion kit, it is going to be fitted to mostly older bikes with cable brakes!

Not really... good hydraulic brakes are just much better. Try them.

I assume only small percentage would use rim or mechanical disc brakes.

Why do you say that?

 

On my TSDZ8 power doesn't stop immediately. I might test it more, for example on full assist while on a steep hill when I can hear motor a bit.

 

Much depends on how you ride your bike. On road it doesn't matter that much.

For off-road brake sensors are essential IMO and TSDZ8 is designed mainly for off-road.

Brake sensors are a bit like safety belts or air bags. Better to have them and don't need them than need them and don't have them.

 

For Woosh including brake sensors would probably cost less than £5, so considering price of this motor it would be a nice gesture (IMO of course).

I already ordered brake sensors and intend to install them.

Tongsheng does not make hydraulic brake sensors, that's the problem. I will have to buy them in and throw away the sensored levers.
