Endless Sphere

Awesome build, fast and it looks fantastic, and you built it on a pretty tight budget which takes a lot of commitment. Glad you are happy with the result

Looking forward to more video. The construction of this bike is so awesome!

Great build and thanks for sharing. Very nice mix of power with low weight and a touch of hand crafted design. The floating triangle battery imbues a lightness to the asthetic.

CD that blue looks amazing, great choice. What's the rim width?
Component wise I'll probably run a Sun Ringle Duroc 35 front (30mm), spare 180mm Rockshox lyric, used 57mm Fox CTD, TRP brakes supplied by LMX,11-46 cassette with SLX shifter and mech.
Better turn my attention to a battery.

Polycarbonate, what do you intend to use it for? Keep in mind it's hygroscopic. Edit, just realised your comparison thickness varies so maybe the acrylic depending on the application.

Congratulations, inspiring to see such focused collaboration and engineering capability benefit the EV community. This is a so awesome!

Polycarbonate is hygroscopic, I am not sure if this affects the suitability but worth considering.

Thanks Adam, fwiw I think those looking for a larger battery should consider inserting a pack with the rear wheel and shock removed, or a two piece welded pack, or a modular NESE at 14s8p. Note, this opinion is based on my rudimentary estimates so consider with caution.

Also still after the detail on the second battery mount...is it an option or not?

Exactly, these bikes are a significant investment please keep the early supporters informed. Also, if paint options available a customer email might be a better idea than an ES post.

The discourse about measurement accuracy and precision is fascinating and worthy of a standalone thread with examples/ industry standards. I appreciate EG's effort and those skilled in analysing the real world charcteris of motors, controllers and measurement devices.

Lots of charts and various sources in this thread so I thought this report is of interest: https://www.lazard.com/media/450773/lazards-levelized-cost-of-energy-version-120-vfinal.pdf The premise of the link is an Illustration of how the levelised cost of energy (LCOE) derived from wind and utility-s...

Congratulations Chris, really cool is a huge understatement. I've followed your work, and the research and development to produce this as a viable product deserves its own paper. Massive respect for pushing the envelope to adapt LiPo to such an unforgiving Australian climate. I can only imagine the ...

Hi Chris, did you fill your recent order MoQ and complete the order? Let me know if you didn't, thanks

Congratulations on achieving your goals. In the preorder offer, can you please consider supplying a small batch of developer kits? For example, supply frame only with motor, rear hub, and drive sprocket. Might help those that want to support LMX but struggle with the full cost of 4583€. Does this ve...

Congrats Recumpence, you build some wild ideas and this is so unique I've been following with interest, thanks.

Hi Dan, I am in Brisbane and I have been looking into purchasing a carbon frame with the M600. Are you selling the ultra frame because I am after a bike for my better 3/4's. I hear some of the suppliers will ship to multiple locations so may not have to be Aus only group buy. Although, would be easi...

Hi James, I'm interested in a new controller. Based in Brisbane.

Outstanding write up, thanks for sharing this information. Much milling did the case? Looks like a .5mm on the large section. Please let us know if/ when you hit thermal protection on the phaserunner. Cheers

Fantastic design, congratulations on improving your design. I am suprised trellis frames are not more popular. The Dogatti bike had a trellis frame if I remember correctly. Great work and thanks for posting the geometry details.

Nice progress, the cat seems happy. Amusing/ interesting design evolution considering the original design, and now the twin spars are working with a spaceframe to holding batteries that replace a very traditional stressed member. Off topic but seeing a KTM freeride battery made me consider options f...

Freaking awesome, thanks for sharing the renders and details. I've ridden a few Buell's and my impression is the front end can be a little twitchy on change of direction under power. I imagine you'd have a better idea. From a semantics perspective over constructed equates with under engineered not o...

Great project, nice to see the motor didn't go to waste. Did you fabricate the gears?

I have the same question and would love to hear from anyone who has regularly transported two adults on a cargo bike. For example, a Yubda Mundo or similar. All opinions welcome, prefer not to go with a tandem.

Thank you for sharing the test results. Logging cell temperature or even just peak temperature would be a very interesting, particularly at the higher discharge rates.

If you are willing to optimise the system for 16S you could use this product: https://www.energusps.com/shop/product/ ... 0a-750a-36
Discharge/Charge/Regen current 750A if used with external relays, current sensor and mounted on a heatsink.
