I have been watching to see if there are any updates in the last 2 months. are there any ? When do you think you will have a rolling chassis for sale with wheels wind screen etc. ? What does it weigh without the motor and batteries and controller ? Not sure if you plan on selling a complete bike , o...

I did not see it on ebikes.ca , I did e-mail them a few days ago but they have not gotten back to me yet, I understand they are always busy . So / means divided by ? in other words Dived the Volts by the amps ? , so if I have 10 amps I would divide the volts by 10 amps ? It is so much easier in the ...

1) Looks like the controller is not working as it should, don't know if the factory that makes the controller for GNG made a mistake on programming , or , if the Fets / Caps / and or Shunts are not good enough for a Real 72 volt controller . A real 72 volt controller should have at least 90v or 100 ...

Has anyone one used a regular hobby lipo charger to find out the shunt value on a controller ? ( I found a you tube video from someone who used a iCharger that has a 10 amp Foam Cutting feature , however , none of my DC to DC chargers have this foam cutting feature ) https://www.youtube.com/watch?v=...

I will have to check to see if those cheep $ 40 controllers have the C.A. plug. I had a chance to buy one but it did not have the C.A. plug so did not buy it, I have no idea at this time how to make a C.A. work with a controller that does not have a CA plug. Shipping from Grin to me is at least $ 12...

From What it looks like in the picture it has a white protective cover over the wires , and under that it looks like they have a wire that spirals around the main wires , It looks like they are the only two parts that touch the rotor bolts , not the main wires. Cut back an inch or so of that white c...

I have a Lyen Controller 9 fet 3077 mosfets , from what I can see on the outside it is exactly like the controllers vendors like eM3ev.com and others , sell that list them at 48 volt 30 amp controllers. How do / Can I exchange a couple of parts inside to make it work on 36-72 volt and 40 amps ? High...

Trophix, Since others here have stated how you look more like a motorcycle when using obvious motorcycle gear , I need to explain myself more than I did above. The items I listed can look like bicycle gear in the following ways. First There are Long Finger Gloves that Down Hill Riders use, they look...

Wtuber, I know, I am always looking to the Future, and even without a crystal ball or being a psychic I know those laws will change. The young generation is wanting a green deal, and the best and cheapest and at first the only way to lower transportation pollution , is with high speed bicycles and t...

ozzzz , Thanks it was a real nice ride , I had the hall sensors replaced on the motor and at the same time the person who did it put larger phase wires on it a real tight fit for the wires going into the axle after that mod. I sold it many months ago , during the rainy season to a local person who s...

Bump, to let readers of the original Electrom thread know about this new and improved version.

davidmt, What happened to you is the reason I now only buy Shimano Rotors . ( no rotor bolts coming loose on any of my 3 conversions ) When buying a new Shimano Rotor it comes with the following ...' 1) Rotor Bolts that have Quality Locktite 2) A thin metal strip with a tab on it that helps keep the...

Besides a good helmet, 1) Good Gloves 2) Kevlar lined Jeans ( buy at any motorcycle shop or online ) 3) Icon (or any other brand ) of Chest and Spine protector ( Also Down Hill Bicycle Versions that are sold at bike shops that have down hill bikes and /or are located in Mountain areas ) 4) Good foot...

I am not sure what quad you have ( You should post make and model ) so I do not know how the rear wheels are driven with the chain, But with a Guess , the best system for you would probably be a " Stoke Monkey " system from Grin. That would also allow you to use gears , helpful if you live anywhere ...

All the tadpole designs I have seen have what is called a " Unified Rear Triangle " , and with that kind of design the pivot points are well ahead of the axle .
So
The Rear seat and chain stays will flex a little, and thereby put less torque on the pivots than a Horst LInk Design.

Interesting Voltage , are you saying you are getting a 12s battery pack ?

23.8 Ahr pack Nice , I look forward to the day when I will have a frame that will hold such a good size pack.

Also the putty/epoxy that Jackson flicked off with his finger that was put on to balance it is a Big Problem. It would only take another 10-20 minutes to balance it properly , however until GNG balances it right they will be spending Hours dealing with pissed off customers demanding they fix the mot...

I laughed when Eric was confused about the price, early in the video he was hinting that it was not worth $ 600 , then one of his crew clicked on the GNG website and showed it is $ 800 which got Eric even more disappointed in it. Eric , it was $ 600, $ 638 give or take a couple of U.S. dollars, but ...

Which part failed ? the piece that looks like a Sram XD Driver ? or the cog/cogs on that piece ? Is GNG going to ship you new parts under warranty ? ( no cost ) Let us know how long they take to get your new parts to your home. First ride on my kit today. This thing decided to desintegrate. Other th...

Would like to see a review and tests of the LiHV lipos that HK sells. ( Does anyone else sell them ? Can just the cells be bought ? ) As much as I like the design work and manufacturing of the Luna Wolf packs, the Em3ev packs with fuses , and the Grin LiGo packs, they are all way over my budget rega...

Excellent, When you get time after you get it ready for market , designing and installing outrigger wheels that deploy when coming to a stop so that you do not have to put your feet down would / will be a good option to buy . that way you can install some sides and a top for the fall/winter/spring w...

Interesting, How much resistance will be in the 16 awg wires that are left in the motor ? Won't they heat up for the amps you will be pulling through them ? Would like to see an electrical engineer compare the difference in the ability between replacing the phase wires from the inside of the motor t...

What guage wire are the Phase Wires ?

What does it weigh before the freewheel / brake disc rotor ?

Very Good, to have different plates for the different style frames . :thumb: In regards to someone saying that 350 watts in enough ... No it is not. I live in a Hilly area , I often am seeing over 1k watts on the Cycle Analyst when going up hills. Add to that at my Age I have arthrits/ inflammation ...

Paul, I see on you have installed this motor on about 6 or so bikes ... all of which have straight down tubes . ( Straight from the head tube all the way down to the BB shell of the frame ) Many people have full suspension bikes that have what is called a dog leg , down at the BB area of the down tu...
