Re: Nomad - Brat Enduro ASI8000 build

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 :bolt: :bigthumb: :bolt:

Re: 27.5 plus mid drive

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.

Re: E-S LMX 64 Bike Owners

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.

Re: 2mm Polycarbonate vs. 3mm Acrylic

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.

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

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

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.

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.
