Re: Sur-Ron - New Mid drive Bike

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...

Re: Suzuki GSX-R e899 K2

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...

Re: Nucular electronics - complete kit for ev! [beta]

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.

Re: 48 v 13A battery

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...

Re: Statorade vs generic Ferrofluid?

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.

Re: 2 chargers won't work TaoTao ATE501 scooter

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...

Re: DH frames for freeriding

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.

Re: Project Dirt Cyclone / DH frame / 52V Li-ion

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...

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...

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... :wink:
