Skeetab5780,

7 kw bursts? That’s low.

Be sure to get a big enough controller for 7kw++.

Mine may have did 136.6 amp x 80 v = 10,936 watts.

The Votol EM 150 controller that first powered the QS3000 edirtbike, then next moved to the QS2000 edirtbike, is now on the QS1000 edirtbike. The controller has never been programmed by the rs232/pc method by me as it worked quite well on both the QS 3000 & 2000 motors. Since the QS1000 motor/EM...

larsb,

I will be monitoring with a CA. I did try a 200 amp shunt but the analog RO needle bounced around too much for pinpointing an accurate amp reading.

Hi larsb, Thanks for informing me about how one may override the declared maximum current of this series of Votol EM controllers. I still have the 4 wire USB cable and have found a friend with a PC & USB port, so I may try changing the max current on the EM100. For now I will install on this bik...

I had a few hundred 18650 cells and wanted a useful way to employ them in an RV. The Magnum Dimension CSW 20-24 inverter can use either 12v or 24v as input. The upper voltage limit for when the inverter is set at 24v is 30 v. So I made 7s packs. 7 x 4.2 = 29.4 volts < 30v and the inverted works fine...

The Dun Electric store is in Malaysia and there is less or no email censoring there compared to what China does. So emails do get thru to your contact. The Dun Electric web store displays only a small selection of ebike parts but I have got specific items from them that are not on display on their w...

Amberwolf, Thanks for the suggestions. They were helpful and motivating. 71867BC5-D992-40BB-B81C-F662959DCD95.jpeg From the CA set-up calibration. We see B51F0EA8-23A1-4DF8-8B78-1DF0D5C62199.jpeg Amps corrected 107.8 amps x .76 mohms/1.0 mohms = 81.92 amps which is reasonable as another bike’s CA ha...

A CycleAnalyst was installed on the Broadie QS1000. This morning I converted an old CA-DP model to a CA-DPS so the bike now has a wheel speed sensor [it was a hub motor speed setup] The instrument does read out instantaneous watts. A new shunt from ebike.ca was also installed. After the CA installat...

Paul of SBP told me in December that he might continue selling items such as the White Industries hubs on eBay.

My last texts with him were in Dec. this # may still work:

liveforphysics,

Not all ‘proper bikes’ are tuned ideally — like yours? “Those That Forget History Are Condemned to Repeat It”

Encore?

Plugs aside it seems our vapor expert has vanished and dropped the ball of this topic? So be it, I will make a statement of my mildly empirically gained knowledge of lessening vapor intrusion — no pico meters used here. If you want good conduction in those Hall Wires under “wild” environmental condi...

liveforphysics, Sorry to hear about the wheelie accident that hurt your leg using this machine. Were you experimenting with Newton’s Second Law of Torques when applying the Dirac Delta Function as IC’S to the DEQ’s while expecting to get the erogodic progression of a random event for the mechanical ...

DanGT86, Yes, there is a niche where you have a good lightweight elec MC that has more durable components than are available as bike add-ones. We are both looking at ways to get such a fitting? As for getting such an item, I have so far acquired the kx100 and 2 QS geared motor sizes. It has been goo...

DanGT86, Quality exits — you state 8” of travel but you fail to state what brand of fork? The Rock Shox dual stanchion fork is cheesy mush. Certainly bike components used in conversions have the obvious additional weight limitations for a rider. If you seek a mere 20% sag with the Fox X2 Float on an...

harrisonpatm, Certainly there is room on the trail for those that bought the UltraBee or any of the other like edirtbikes for whatever reason. As cool as these bike/MC hybrids look, I suspect I would be underwhelmed having paid for one. The cost of converting a good DHB to make an outstandingly good...

DanGT86, Thanks for posting the specs of the Super Bee. They do give me a useful reference as to whether to buy one or put my skills to use on a used MC conversion. A comparable [or likely better ] MC frame would be that of the Kawasaki kx100. You can pick up a running used one for under $2000 and s...

Having built 3 edirtbikes with 3 different motors — the Cyclone 6k, the QS2000, and the QS3000 — I was left wondering about what the QS1000 motor could do? The wattage this series of QS motors can handle is about 10x the model number or 10,000 watts for the QS1000. The very lightweight QS1000 motore...

$9299 but OOS.

Fitting the Rear Fox Float X2 shock 8F52AF83-D2D2-4633-B53C-A763A798784D.jpeg The Fox Float X2 rear shock does not have a big steel spring, just air and oil to allow it to out perform the older heavy steal spring versions on downhill installations. It does come with two spacial costs. The high volum...

liveforphysics, Thanks for vapor intrusion issue detail of the 6 pin plug I mention. For zone 2 protection, how does the thermal glue enhanced heat shrink tubing applied with a tight fit to single wires hold up to vapor intrusion? It does seem to [am I getting serious vapor intrusion?] work with mos...

There are two regions of electrical conduction impeding processes/sites that happen in, on and around electrical contacts. 1. The zone on a contact that is the pathway for current carrying likely does better at conducting with a conducting grease applied to it’s mating surfaces. The connection must ...

Electrical wires in operating ebikes corrode, but not all claims of satisfactory conducting agents lead to what will work well for the low and high DC voltage contacts of these machines. Dielectric grease. Why not? It is non conducting. [AC]Electricians use: F2AD67DB-C1C1-444A-84C4-B432311A5679.jpeg...

Mxlemming, You have asserted “…the conclusion is so blatantly correct…”. What conclusion? That the fella did not assert any conclusion is my point of the thread. You now are making conclusions about conclusions out of thin air. Please, what premise, what conclusion? And this nerdy statement aptly ap...

Does that motor need the $1900.00 High Voltage tuned ASI BAC8000 controller to break 70mph at the mere high voltage[ as displayed in video] of 72 volts using some 14,000+ watts? The Fardriver ND72530_24 can get my bike to 70 mph with just over 10,000 watts at a cost of <$300. Or get the Fardriver ND...

The Sur Ron was considered a motorcycle not an ebike by the site administrators. It’s site location was then moved out of non-hub motored ebikes to electric motorcycles.
