Endless Sphere

Exactly what I was thinking about too...I will try But can they ship to EU? No idea, and I don't even know if they are reputable, I find it strange they are that much smaller, I would want to see pictures of the pack being built with a tape measure next to it... It is also expensive for such a smal...

Hi folks, I made a paper mockup of this pack: https://em3ev.com/shop/50v-14s7p-rectangle-battery-pack/ Dimensions: 81mm thick. 324mm long, 140mm wide. https://em3ev.com/wp-content/uploads/2016/08/Rectangle_14S7P.jpg Did you try a mockup of the ElectroRide I mentionned in my post above it is a bit s...

From my preliminary work (I got all hub dimensions for Kindernay), but without the info I am looking for, I believe there may be a way to do it. Yes it would require machine tooling an extender for the torque arm, which requires machining the spline profile so it would require access to a CNC machin...

Hi again, I would really love the LMX64, but without a derailleur (to each their own, don’t shoot me :) ) While my ideal gearbox solution would be a Pinion C1.9XR to get the range with less gears, and centered weight distribution, this would require major surgery on the frame, and poses a problem wi...

You should also investigate the vertical layout. At least for the bottom half of the pack, I think it might result in better energy density. I checked, but when positioned vertically, 4 rows in honeycomb comes to 69mm and 5 rows to 85mm. If we could do the 5 rows we would gain substantially, but it...

Humm... I just checked the highest capacity Samsung 21700 and I got the following Samsung 50E: 21.1mm x 70.7 mm = 24,722 mm3 3.6V x 5Ah > 0.2023 Ah / mm3 That is only 2% more than their 18650 35E So where is the 20% increase in energy density?? Am I missing something here, or the 21700 just have not...

I can do some 21700 mockups, but I wonder if these have proven easy to make work in battery packs...
I only remember Luna saying they had huge problems when they first tried to do the Apex battery pack with them. They ultimately gave up and went back to 18650 from what I read.

here are the dimensions we have to work with .... Brian, can I solicit your measuring skills one more time ? :) Could you measure the space between the Rear engine sprocket (the large one) and the rear disk brake (between two sides facing each other). I am trying to see what is the minimum clearanc...

Also, regarding the higher capacity battery, I think it might be easier and allow higher capacity to run pouch cells. It would just be a matter of finding some that are the right dimensions to fit. This is what I already tried (and failed) when I ordered 14 x 40AH cells with the idea of stacking th...

Based on the dimension Brian gave me, I played with the following scenarios for an extended battery inside the frame. As a One piece battery, It would seem we could do 14S-7P (98 Cells) or about 1,200Wh and may be even 14S-8P (112 cells) or about 1,350Wh, with an optimized pack and a cover (see draw...

Perfect, Thanks

Thank you so much Brian.
To make sure I understood your pictures properly

• Inside width: 94 mm

• Length: 340 / 350 mm

• Clearance at the top (between down fram and to tube: 90 mm

• Clearance at the bottom: 140 mm

• Height of the frame U box: 74 mm

Hi Brian,
Can you give me the width and length of the open area inside the frame, as well as width length and height in the covered part at the top (if not full of other stuff)
Thanks

I think It would really benefit of a 14S6P but I test-fitted a cardboard model of the big 91 cells Hailong case and unfortunately I think it would not fit, well it fits once installed but you can't install it. Has anyone considered making an extra battery made of 2 or three layers of cells in honey...

Regarding the cadence thing, it is something I requested from our controller supplier a while back and recenteley asked about again. It's not really the cadence, but the human watts that should be used when the torque gets lower due to higher rpm on the cranks. Adam Thanks Adam, Appreciate the upda...

Thanks ,
So 57.5mm on the motor side and 70mm on the pedaling side.
Did you measure the center of the chain?
On the pedaling side 70mm sounds like a lot, did you have the chain on the middle gear?

Thanks again

This is when i notice that slow pedaling on a singletrack is not ideal on the LMX64. The pas delivers power very unevenly and is far from the feeling you get on a Shimano steps system. This might not be surprising due to the raw power of the 64, but it would be nice to enjoy a smoother pas ride. Th...

What do you mean? Are you looking for chain length or sideways chainline (if so, how do i describe that)? What I mean by chainline, is the distance between the centerline of the bike (middle of the bike in the longitudinal axis) and the center of the sprocket. https://bike.bikegremlin.com/1755/bicy...

Anyone knows the Motor chainline and the pedaling chainline on the LMX 64?
Thanks

Hi everyone, I came across a bike called Steiner Ultra E bike online on two different sites below https://www.orangebc.com/de/produkte/fat-e-bikes/steinerdesign-ultra-ebike-fully-27-5-plus-rohloff-gates-karbon-riemen-speed-pedelec-zulassung.html https://www.steinerdesign.net/produkte/bikes On paper ...

Nice design.

It reminds me of the old Husqvarna prototype
https://www.topspeed.com/motorcycles/mo ... 27835.html

I hope they come up with an extended battery solution. 1.8kWh seems quite small for such a bike...

So, my EX has arrived. First impressions? WOW IT'S HEAVY I opted for size medium, the dropper post, front/ rear mudguards, front/ rear lights. RockShock Lyrik upgrade and the rack. This monster [without the battery] tops the scale at a monster 34.74KG or 76.b Lbs. There's no way my Mrs will be lugg...

Hi everyone. I have not been on the forum in a while (since we lost all hopes about the Neematic :) I had not been following LMX in a while and was thrilled to find out they had implemented a torque sensing based pedal assist and have apparently done a good job of it, and that they also managed a Ca...

Initially gates forbid ALL tensioners until riese and mueller decided to do it anyway and find that it worked fine. When you see what belts can do and take in other usage scenarios, I still believe these belts have a lot of extra strength and that they could probably take it, but someone will have t...

The belt drive has no tensioner (like the chain drive has) to take up the slack as the suspension arm moves through it's travel. You won't find much when searching for FS with belt drive. The reason tensioners don't work with the belt drive, to my understanding, is even without them, keeping enough...
