So where your at what does “moped regestation” let you do as far as speeds and trails? Insurance and motorcycle helmet? I like cruising around low speed.....20 to 30 mph and see all the sights. ‘Slow down and smell the roses” so to speak. I wonder if they will ever ship the EU street legal one to u...

You seem to be spending a lot of time and money for a few drag races that aren't that quick. I understand the attraction of buying and building but can't understand the lack of riding pleasure it results in. Why not built an electric motorcycle you can ride on the street and enjoy for many more mile...

Basically a "legal" mode that can be set easily when pulled over. As the speed and wattage vary per country or state, it needs to be programmable to the desired max speed (rpm) and output watts (amps). I think that a simple switch option could do that when you hide a wire with a reed switch glued to...

I was told all the newer MY1018's had the helical gears and were quieter than the early straight gear models

That might explain the great difference in noise from videos I found on Youtube. Some have the gear whining sound and some are much quieter and more pleasant to hear.

I can buy XYD16 for 74 euro

Do you have a link for that motor?

What an overload in specs... Maybe you could add the brand, type and arrangement (nr. series/parallel) of cells, how it is built (professionally/by you) with or without cell holders, what BMS, type of case, etc... And it isn't 13A but maybe 13Ah? So what is the maximum amperage and continuous rating...

Great to read these good results. I'll probably order a motor soon. Thanks for the contribution!

Watch out as some types of "regular" ferrofluid are based on more aggressive oils/fluids that may dissolve the glue that holds the magnets in place. There is a thread here on E-S about ferrofluid with this info.

Is it a series of SLA (lead acid) batteries or a Li-ion battery pack with a BMS (battery managment system)? If SLA: check each battery for voltage and connection to the other batteries. If Li-ion with BMS: check output voltage of pack at BMS and reset BMS. Check all your wiring from the charger to t...

...mass centralization is key. I rode a new Zerode Taniwha last week with a Pinion gearbox, and I can feel the difference not having a cassette/derailleur hanging on the back wheel. The bike is so planted, you can feel how light both ends are. Let's not sacrifice the ride for the sake of easy drive...

No.
Read back in this thread what is possible with the firmware.

--- as an aside ---- I've just tried to opt in for a 48V 750w TSDZ2 and no-one on Aliexpress seems to list it today. I only reviewed the options three days ago and there were plenty of sellers. Can anyone else bear witness to this? I'm in the UK. I was going to order from recycles-ebike.com but the...

DH frame would be a great choice and the slack head angle can be sharpened a bit by lowering the preload of the front springs or sliding the fork tubes up in the crowns. And a longer rear shock can help raise the rear end.

Would love to have that motor in a 24" rim with a PhaseRunner on 60V

If you mean the small brown weld spot that prevents the cover ring of the freewheel from loosening that seems "normal" as a solution for a problem some customers might have had.

Great build ingredients, I'm going to follow this. Good luck and enjoy!

The motor I have selected is an old school brushed MY1018 450W 24V that is stated to be able to run 36V without issues. It is the smallest and lightest geared motor I could find that seemed to meet my needs. The one I purchased is said to be rated for 25A as well, but I am not sure it will run reli...

Too bad they are so expensive but I always thought that for a cruiser/chopper build a powerful water cooled hub motor would be ideal: http://www.cnqsmotor.com/en/article_read/QSMOTOR%2017X4.5inch%2012000W-14kW%20273%2096V%20120V%20Water%20Cooled%20DC%20Electric%20Hub%20Motor%20For%20motorcycle/538.h...

With those requirements it seems a Qulbix is way overkill.
Why not just mount a mid drive motor kit like a BBSHD to a decent MTB?

:lol: First I thought you were very sensible to use a complete salvaged Nissan Leaf. But then I read that you're thinking of using the Beetle transaxle gearbox and mating the Leaf motor to it? Why on earth would you want to do that if you can just mount the complete drive train (including the gear r...

If you are looking at using a salvaged Nissan Leaf and using that powerplant "stand alone" in the Beetle you could use Paul Holmes' control board to get full control of the Leaf's drive unit: https://pandspowerelectronics.ecwid.com/#!/Nissan-Leaf-2011-2017-replacement-control-board/p/125965637/categ...

Great thread! I just started to look into these power supplies thinking of charging my battery pack with one. Seeing these mods I think I'll order one soon from AliExpress to see if I can get it to work on my 16S LiFePo4 pack.

It's exactly like my quality. I don't see a difference.sprocket.jpg

I'm confused, are you saying your quality is the same as Luna Cycles or the sprocket posted in the picture above with all the rough surfaces?

I think he forgot this emoticon:

I wonder if a large smooth pulley with no teeth at all might work, or possibly just some non-skid tape or sander belt material. Kind of the inverse of Kepler's friction drive... That is what Mike has done. He has gone from grip tape to a rubber tape surface for his large rear "sprocket/wheel": http...

That looks like an brushed motor not a brushless one. Then a simpler, cheaper controller will do the job.

No idea. You can ask the supplier who the manufacturer is but even then it's the question if the product that gets delivered is what they say it is. It's always an adventure if you order from China...
