Re: Assembled Hi-Power LiPo battery packs - any interest?

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 ...

Re: LMX 64 : Freeride Ebike with dual drive and torque sensor

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...

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...

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.

Thanks for posting the detailed images. Inspirational for an amateur like me. I hope you can successfully repair the controller. Did you choose the PTFE to reduce size or just for general durability?

Hi Maddin, thanks for posting, quite an inspirational build. Interesting use of adhesive. Couple of questions if you don't mind, did you include a 'fence' on only one side of the pulley to aid machining? No need for a fence on the second side?

Alex, I share your beliefs and agree cooperation between niche builders could reduce fixed costs and offer scope for innovative ebikes, as opposed to motorcycles like the Suron. The difficulty will be to agree on design scope and functionality. I'd suggest a 0 to 3kw design (continous) and 3kw+ desi...
