Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

I use a 52V battery and most terrain I ride is hilly. I'm lucky to get 30-40 minutes of ride time before overheating at medium assist levels. I'm not sure why you are bothering to be part of this thread, even you would have to admit to compare a Bafaung HD to a TSDZ2 is like comparing a mini to V8 ...

Re: New "TSDZ2 Torque Sensor Central Motor"

At that sort of level of sound, you have an un lubricated gear mesh which is very wrong, or a bearing which is damaged.

Re: New "TSDZ2 Torque Sensor Central Motor"

We are finding within our group that those who run the units consistently with high power, that their motor units do become noisier quicker. We have found that re greasing the big gear and helical drive gear helps as it is in reality a steel on steel gear that is working hard in a non oil bath situa...

Re: TSDZ2 wireless mid drive motor (like Specialized Turbo Levo) -- Flexible OpenSource firmware

An all singing and dancing bluetooth keypad solution is the ideal, the not so ideal is having one ver...

Re: paralleling in battery packs.

Yes the voltage difference is going to be some 14 volts and as far as I'm aware you could damage the cells or BMS if we were to simply parallel in the batteries. My original thought was that there maybe some small piece of electronics or simpler diode based way of isolating each battery from each ot...

Re: New "TSDZ2 Torque Sensor Central Motor"

Look up how an XRing seal works and you'll understand that the Oring part is actually stretched over the bearing and can't slide, its the outer lip that then seals against the inner section of where the seal sits within that plastic cover. Seems odd and contrary to a normal seal.

Re: New "TSDZ2 Torque Sensor Central Motor"

It does look like anti-seize but I can't think what purpose it would serve there and why it's made such a mess. My motor only had grease in that area. I found this picture of an older model (with silver spider) which shows a different cover with a wider gap, or is it an outer groove? My newer motor...

Re: paralleling in battery packs.

Yes that's what we do already, but it would be nicer if we could have the main battery as a semi permanent, frame mounted, that we didn't have to remove when we put the 2nd battery on.

Hey ho, what we do already is not that inconvenient, so we'll stick to doing what we already do.

Thanks All.

Re: New "TSDZ2 Torque Sensor Central Motor"

Be careful with all your shimming that you don't pull the torque sensor on the crank too close to the sensor on the controller by moving the crank too far towards the non drive side.

Re: Dreambuild EMTB Dengfu M09/Luna X1 Bafang M600 with a slacker fork angle/Increased wheelbase

Not sure, I would sooner have a minimum weight battery than over weight battery that you would only use 50% on a ride. If we can fit 14S3P of 21700 cells it will be more than enough for my needs.

A question why the M09 and not E10 ?

Have you ever weighed your bike all up less battery ?

Re: paralleling in battery packs.

Sorry yes we have the cutoff set at 44 volts and not 39 V ( 13 S battery ) A 13s battery only charges to around 54v, not 58v. So are you using a 13s battery *and* a 14s battery? Or do you just need to get all your numbers straight *before* you post? ;) If youre using two different voltage batteries...

Re: paralleling in battery packs.

If that's a 14s battery, based on the 58.4v full discharging it down to 2.7v/cell isn't really a great idea. Uusally about 42-45v is a more normal cutoff for a 14s battery. Otherwise you'll have to unplug the empty one, then plug in the full one. If you want to literally switch from one to the ohte...

Re: Dreambuild EMTB Dengfu M09/Luna X1 Bafang M600 with a slacker fork angle/Increased wheelbase

Dengfu's E10 frame already has a slacker head angle off 66.5 degrees and with a Mullet ( 29er front wheel ) arrangement would be even slacker. Would you need any slacker as the bike will be getting into that dull feel of too slack a head angle that used to be the realms of downhill bikes. Just about...

The question should be is the chain line actually giving problems, mine is similar and with the addition of a front chain guide ( previous front derailleur ) I'm not having problems.

Re: New "TSDZ2 Torque Sensor Central Motor"

Be careful on comparing drag with the motor off. The largest " human feel " difference to me is that most commercial motors are geared so that the outer chain ring is a 30T where as the TSDZ2 is a 42T. The commercial bikes are geared to 25 - 35 kmh max ( in the EU ) and thus can run the small gear a...
