Thanks for the kind words! Totally agree that consumer eMTBs are pretty astronomical in price for the latest and greatest tech (although right now, depreciation is hardly a thing for eMTBs!). EX-E and Relay are both amazing contenders, and ride great. I do get much more power from my build, but...

Just a video overview: LINK

Thanks for the data point! Good to know you're doing it successfully. I do fully charge and balance for each charge cycle. I suppose it's worth trying - I have the materials needed to do it. This is great, I'd rather parallel than series for many reasons.

Fair enough, I could switch to a BMS with a shared charge/discharge port. What's an ideal diode? I thought that was a mental model to use for calculations, is it an actual type of diode as well? Wondering how I'd test if my separate charge/discharge ports are really behaving this way... Also...

Thanks! My concern is that I do want to push these cells at their MCC, since the controller can take so much. The solution here is probably to just make smart choices in BMS output ratings, which I should just go ahead and do. In the previous post, I'm just ruling out a parallel config without...

Wow, it's been a while! I have small updates and then next steps: I removed the winter camo livery from the bike and took it to Red Rocks in Las Vegas: Those rocks are gnarly and left me with a real bad pinch flat! WHAT'S NEXT: I'm starting to think about a range extender. It's not really...

Thank you kindly! Much appreciated, clean is what I'm going for haha There's not room in the shock cavity, the shock movement uses all the room :( I've considered enlarging an existing hole at the bottom of the frame (a mounting hole I don't use anymore), but it's hard to justify cutting into...

Okay I upped my Street Mode to 500W instead of 250W and it completely changed the ride. Now my lowest assist setting is too powerful to not ghost pedal! I think I'll set my lowest assist setting back to the original setting and give myself the option of upping all the way to high power on...

You're totally right. My last post was a brain-dump riddled with logical holes that I hadn't worked through yet. I have the 11/53 gearing, which is the lower torque / higher speed gearing. Shame on me. I haven't found a 10t 219H B-type sprocket that would fit my motor shaft, and I'm not trying...

I rode my build side-by-side with a Specialized Levo SL this weekend. My takeaways were that my bike feels considerably bigger (in suspension travel, frame size, and weight) and that the SL feels like the motor puts out considerably more power than mine. The second takeaway really bugs me. I...

Update on the cable organization: I found some offerings from some bike companies that I might try instead of designing my own. Jagwire alloy guides at Jenson...

MONEY TALKS (how much did I spend?) This was quite a build - I dug into my credit cards for a bit on this one. Below is a screenshot of the cost tracker that I keep: Takeaways regarding money: For a performance mtb build, the frame is by far the largest cost. I don't think I overpaid - the...

Here are some pics I took today: Two cables, zip-tied together and hot glued Big harness junction hot glued Another that already came off Blurry pic of my speed sensor

FIRST LOOK ...And here, we catch up to present day! I installed the battery according to the SOP that I created in my head - it's very regimented now. I tweaked a few settings in the CYC and ASI apps (battery voltages and thresholds, assist levels, and speed limit so far). I've been on a...

Did the location, thanks! I have the DD casing for the extra weight and gnar, and sealant inside everything. For riding here for several years, no problems even without the DD casing. (I hate tubes) Thanks! Hey, part of the reason I'm posting this is so others might get the idea to do the same ;)
