Endless Sphere

the people that are discussing the hacked firmware in this forum I wish you guys could correctly refer to our efforts: we are developing just like Tongsheng engineers did. I am also an engineer and working professionaly as a firmware developer, for a Germany company that develops top technology for...

Hi guys. I wrote above that I had a problem with the motor. It looked like this. If I pedal without the support of a motor, then the bike perfectly rides off my leg strength. So the clutch that transmits the torque from the pedals to the wheel works. But when I turn on the motor support, volume whe...

Sigh. I give up. Not going to read this topic anymore since it's 99% hacking talk that's of no interest to most purchasers of the unit. Me too. Hi. There is another option available, it is not perfect but it is the only method that I can think of that might be of help to you. You can go into your s...

I respectfully disagree with the motor powering up the instant the pedals move. Perhaps this would be useful for racing applications (750w racing motors - lol), however you are just looking for trouble. Sometimes you get your weight on the pedals and then decide at the last instant to not go because...

Hmm ?? its not always clear which is the plug and which is the socket.. !!

I hear you. I thought it would be the connector that mattered but it appears to be the pins that take preference. The ones with male pins sticking out appears to be the male connector.

I am studying e-assist motor options for installing on a recumbent trike. I am not sure about greasing the bearings, I believe at least some of them are sealed bearings so you cannot get grease into them. People that replace the vinyl gear with a metal one have been greasing the motor gears due to ...

Are they also taxing parts (like mid drive motors and batteries) or just the complete bikes? 25% may sound like a lot but it is only $50 on a $200 motor. Perhaps these tariffs may also help people that are converting traditional bikes to electric on a small scale. A company manufacturing a $2000 ebi...

And what is with Portugal's National Obsession to tailgate? In ANY kind of weather? 140 kms/hr in a driving rain on the way to the Algarve & I'm being tailgated. haha - We pulled off at the next truck stop & waited for the weather to improve. I think everyone there thinks they are Formula One Drive...

We are glad you are ok! Hopefully you were not hit and run, California is a cesspool for hitting bicyclists and motorcyclists and then running home to buff out the damage before they get caught

We hope you and your bike have a full recovery!

Hopefully my display and battery charger will arrive this week. Everything else was already delivered except for the motorcycle mirror mount. I am so looking forward to having a mirror! I am surprised that bikes don't come with at least a left side mirror from the factory. I still need to order a 62...

Hi, it is likely the blue gear has failed however I have yet to experience that so perhaps someone else can help id the issue. You should probably replace it with a brass gear considering that you trashed it so quickly though. ;) The reason why you are pedaling faster than the motor can assist is be...

you can cut the display cable here and install your own connector here inside the housing ? What Eyebyesickle is suggesting is that instead of cutting that wire you attach a "quick splice" connector onto each of the individual wires and then run those "quick spliced" wires up to a new connector tha...

One option is to leave the stock connector intact, but of you open the small compartment behind the chain ring that the wires come out of, you can tap into the bare wires themselves, shove the stock connector end in there for safekeeping, then run out the new wire you made stemming from the small s...

It sounds like the lesson here is that 18a for sustained periods is quite bad for the motor. 18a might be ok if you ride in the upper rpm range most of the time and therefore mostly running at lower power levels. If I can run at 62v I think I will lower the amps to 13 or 14 to be safe. But if you ar...

Hi, About the purchase the TSDZ2 to swap out a Bafang BBS01B. One point giving me pause is the bottom bracket width. My bottom bracket is 70mm wide (Gazelle Cabby cargo bike). There appears to be two widths for the TSDZ2, 68mm or 73mm. Some advice on which way to lean from prior installations would...

Probably because you are the first person that got enough miles out of one of those blue gears to actually have the metal part fail I think Casainho only got 5 miles out of his blue gear!

I'm sorry you burned up your motor Casainho :( I have yet to have my motor cut out due to high temps. I am guessing that going over 750w increases the odds of overheating them, and probably especially when it is really hot outside as opposed to the winter. Also it probably makes a differnece as to w...

The controllers are the same!! Just use our flexible OpenSource firmware to unlock the full voltage possible: 24 volts up to 52 volts battery pack!! I know that Casainho. But they have to order the programming tool and an extension wire, then wire them up and figure out how to use windows to do som...

I think we are having the same problem. Editing the nominal voltage doesn't seem to affect the max voltage setting. The battery voltage has to drop to 55V before the assists works. I have given this much thought already, that is why I ordered the kt-lcd display for which Casainho is making a custom...

I agree that properly tightening the bb nut is going to be the most helpful in eliminating engine rotation on a fs bike. I tightened mine by feel but I suspect it is probably about 75 ft-lbs give or take. I guess it depends on your strength but I like very short wrenches for torquing, this way I don...

I implemented a new configuration menu where now user can: 1. define on LCD the battery numbers of cells (used only to calculate battery state of charge to indicate on LCD battery bars) 2. define on LCD the battery low cut-off voltage Nice dude, I am sure a lot of people are going to like this feat...

I love all the neat designs for motor brackets but you know they do make 250lb tensile strength cable ties. Truckers and air freight shippers use them to secure heavy loads during transport. This motor puts out nowhere near those kind of forces. I am using a 150lb tensile strength one now and it wil...

Adjustment for the pack voltage fron the LCD would be ideal,... Or even "open" voltage range ..30-60v would suit me fine... ......but can we do that with the new software yet ? John, .....i assume you are refering to trying 60v after you have reprogrammed the controller ? You (and others) have alre...

Seems that changing battery low voltage value on LCD could help you a lot, so you could drive with any cell/battery pack voltage combination. Yes, I ordered the kt-lcd already as well as the st-link but I suspect they will take a couple more weeks to arrive. :) I am going to first try the 56v batte...
